Notebook Repair

Things to look for in a laptop repair professional

Competence – Only the professional who is competent enough to take up the job can provide reliable repair services. Repairing a notebook is not an easy job and requires specialized training. Only a certified professional is eligible to go ahead with the troubleshooting of the same.

Licensed technician – Look for the professional having a license to carry on with the damage control process. You must consider a master service provider for the job in your vicinity.

Why consider a specialized technician for help?

  • They are the people who are qualified only to focus on laptop support and repairs and can perform the repair work flawlessly. Not to forget that there are a very few companies that are authorized to handle the repairing job?
  • As they hold specialized training, they can quickly and efficiently figure out the source of the issue compared to non-technical professionals?
  • They have access to specific tools required for the job. With the help of these tools they can diagnose the problem with the equipment along with coming up with a related solution

There are many service centers authorized to do the repairs, but locating the one in your vicinity is always the smartest choice. Finding a professional near to your residential community is effortless. In today’s world of technology, the internet does the job for you. You need to type certified laptop repair professionals along with the name of the place where you are residing, and the search engines will generate the entire list before you. Once you have shortlisted your choice of a technician, you are just a phone call away from him.

The great thing is that they reach you within 24 hours.

All the authorized centers make use of original parts if the need for the replacement of the components arises. Hence, they ensure flawless repairs along with offering value for your money.

IT Asset Disposal

When it says “free”, it does not always mean that

There are IT recycling vendors that will offer to take the assets and dispose of them at no cost to the company. When you ask them how they can do this, they may tell you that they will make money selling the assets for scrap. This should throw up a red flag and make you suspicious. When an IT asset material does have some value as scrap, it is not usually enough to sustain a recycling business that is environmentally compliant. If your company does have to pay fines for a company who is practicing poor recycling those “free” services could cost your company a fortune. So if an IT asset disposal center offers to dispose of your company’s assets for free, look for another service.

Downstream does matter

Many of these companies have partners downstream who they hand off the assets to be processed further and it is usually material they cannot sell. One important thing to note is that your company is liable for all IT assets that you have disposed of throughout the chain of custody. This is from the time it leaves your company to the final disposition spot. To make sure that the company you choose is environmental compliance you need to make sure that all of the people involved are also in compliance. Make sure that you do know where your IT assets go.

Certification

This is the most reliable way to make sure that company you chose is environmental compliance. Generally, there is no one at your company who has the expertise or time to audit the IT asset disposal recycling center practices from start to finish. You do not have to rely on their word that they and any partners are in compliance. Ask to see their certification for compliant and safe IT asset recycling, which are one or both of these certificates, R2/RIOS and e-Stewards. To get these certificates they also have to monitor their partners and provide documented proof that the IT asset disposal is in compliance with all standards and laws.

Dangers of the Online World

As a computer forensic specialist I am currently involved in criminal and civil cases involving an array of different subjects, including corporate data theft and espionage, murder, drugs, fraud, theft, employee misbehaviour, child access applications and even probate. These are not just legal cases either; for example, I regularly receive instructions relating to marriage disputes that involve computers and digital media.

Increased media attention over the past ten years in cases such as those within Operation Ore (relating to 7,000 individuals who allegedly subscribed to websites displaying sexual images of children) and more recently, terrorism and ‘happy slapping’ incidents, have provoked a greater public interest in proceedings where digital evidence has formed a crucial part of the case.

Not only is there now a greater general awareness of the capabilities of digital evidence and its potential within legal cases, additionally, reports of websites containing indecent images of children are also continually rising each year (The Internet Watch Foundation reports that the number of websites confirmed as containing unlawful material has increased by 62% over the last three years). It would, therefore, appear that the use of this type of evidence is set to continue to rise.

Increasing resources are now being spent on examining data of this type as part of legal cases where previously it was thought unnecessary. In the past it was commonplace for a Police investigator to restrict an investigation to simply identifying ‘evidence’. Upon inspection of this investigation by an independent party, as part of a more in-depth review, it was frequent for the evidence as a whole to have been misinterpreted and the case against the Defendant was not as it first appeared.

Over recent years, the majority of criminal cases for which we received instructions have attracted greater attention from the Police. We now frequently encounter cases involving supportive evidence (such as user and/or Internet history) as well as the basic evidence that is relied upon as part of the Prosecution case. However, it seems inevitable that an increase in the number of cases limits what can be achieved within a Police Force’s Hi-Tech Crime Unit. Even today we identify the presence of new and previously unconsidered relevant material within approximately 80% of the cases in which we are involved.

For the majority of the time, this is the result of the initial question asked of a Police Hi-Tech Crime Unit investigator, being “What’s there?” The question “How did it get there?” is normally asked only when the Defence looks to respond to the initial allegations. Consequently, that question is normally answered until well after the case has been initiated.

Identifying the basic origins of a file is normally relatively straightforward. For instance, the location of the file normally provides the biggest clue; the activity surrounding its creation is another indicator. However, clearly, the presence of a file and even the identification of its origins do not confirm that the accused deliberately caused its creation nor was aware of its presence. To examine that point normally requires far greater levels of investigation, including the piecing together of items of data in order to build a history of that given file and the activity associated with it.

Identifying the basic origins of a file is normally relatively straightforward. For instance, the location of the file normally provides the biggest clue; the activity surrounding its creation is another indicator.

To examine that point normally requires far greater levels of investigation, including the piecing together of items of data in order to build a history of that given file and the activity associated with it.

When dealing with cases involving indecent images of children, for instance, there are various methods for an image to have been created on a computer hard drive, including, but not limited to, websites accessed whilst browsing the Internet, received e-mails and peer-to-peer software, such as KaZaA. Within each of these originating sources several possible mechanisms can cause the creation of a file without the deliberate and intentional actions of the user.

One such example is a case in which I was involved within the last 18 months. This related to a 19-year old male who, like most 19-year olds, lived at home with his parents. However, unusually, this young man faced allegations of making and possessing 9 static and 11 moving indecent images of children. The images had been stored in two folders within his ‘user’ profile on the family’s home computer. After two years of investigation by the Police, that included an examination of the family computer by the Force’s Hi-Tech Crime Unit and an externally sourced expert computer consultant as well as a number of interviews and Court appearances, the accused still had not made any admissions of guilt and claimed that he was simply unaware of the presence of the images.

The Prosecution relied upon the fact that the unlawful images were contained within manually created folders of the Defendant’s ‘user’ profile and they also identified the presence of keyword searches for terms that were likely to result in the creation of unlawful material.

I examined the case and noted that the 9 static images had arrived via a small number of web pages containing legitimate adult pornography and had been created automatically by image downloading software. This software, I noted, had searched for and downloaded any images present on any web page that it encountered. A number of further observations were made as to the apparent lack of awareness of the user regarding the presence of the images following their creation.

The 11 moving images had appeared to have originated via the peer-to-peer software named Limewire. The software had been used to download a significant amount of pornography, including these unlawful moving images. Furthermore, a review of the operation of the software confirmed that dubious keyword searches had been conducted and these specific images had been downloaded to a folder that was located within the ‘user’ profile of the accused.

It was only after a careful review of the system activity that was contained on the hard drive did it transpire that another user of the computer had been frequently accessing the folder containing the target images and had been viewing its contents, including the unlawful images. After 9 months of our involvement and nearly three years of investigation, the case was eventually dropped shortly before the set Trial date.

This case is not an exception. In approximately 20% of the cases in which we are involved we have been responsible for identifying crucial new evidence that has caused the case to be withdrawn. Due to the level of examination required to recognise such evidence, this figure is unlikely to diminish. For the Police, an examination of this detail is irrelevant for the majority of cases. Having previously worked within at a regional Hi-Tech Crime Unit, I noted that while I was there, for approximately 85% of the cases in which evidence was identified, the Defendant would plead prior to Trial. Only a small percentage of cases involved a Trial and even fewer were party to a review by an independent examiner.

Cases involving files encountered and downloaded via websites are also frequent areas of misunderstanding. The presence of a web page or file on a hard drive can be the result of intentional user access, or alternatively, the operation of one of a number of different scripts and software. These scripts can cause the user’s Internet browser to be automatically forwarded to web pages containing certain material or cause certain files to be added to the hard drive without the user’s knowledge.

As even legitimate websites contain scripts, the majority of computer users will have experienced (and may have found annoyance in having to close them) ‘pop-up’ windows. These are normally used to forward a user to an advert that often will comprise of a service vaguely relating to the content of the page that was visited (e.g. the autotrader website regularly contains pop-up scripts to websites for car loans or car manufacturers). However, identifying the presence of these types of scripts and software is often difficult. Furthermore, once a suspect item has been found, making the determination as to its nature, ability and activity can be even more complicated.

As digital media increases in capacity it allows users to store more data but also increases the possibility of software or anomalous mechanisms causing the creation and movement of files. This brings with it a corresponding increase in the amount of resources and time required to examine the greater number of processes and, clearly, the amount of data to be examined in order to identify such mechanisms.

Additionally, the increased use in the court room, within both criminal and civil proceedings, of digital evidence brings with it a greater need for the presentation skills required to provide simple explanations of a subject that can not only be difficult to comprehend but also to convey accurately, clearly and without prejudice.

Clearly, the prevalence of digital technology will increase as it becomes even more accessible, usable and capable. This will undoubtedly result in a continuous increase in the number of cases involving and relying on digital evidence as well as increasing the pressure on Police Forces to examine and collate evidence from a larger number of items of digital media.

Tips to Extend the Lithium-Ion Battery Life

Consider the Room Temperature Limits

Ideally, your room temperature should be 25 degrees max. If your lithium-ion battery is fully charged and exposed to a higher temperature, problems can happen. So, what you need to do is avoid leaving your battery in your vehicle if you have parked it in the sun. As a matter of fact, heat is the number one factor that may reduce the life of your lithium-ion battery.

Get a High-Capacity Pack

With the passage of time, batteries tend to deteriorate whether you use them or not. Therefore, it’s important to keep in mind that having a spare battery is not a great idea. Your spare battery won’t give you more power than the one you are using.

So, make sure you understand the aging characteristic prior to buying a lithium-ion battery. It’s better to buy a pack that’s recently manufactured. Another way is to opt for a higher-capacity battery.

Allow Partial Discharges

NiCad batteries have a charge memory but the lithium-ion batteries do not. This means is that you don’t need deep-discharge cycles. As a matter of fact, it’s better if the battery makes use of partial-discharge cycles.

However, there is an exception as well. According to battery experts, you should completely discharge a battery after 30 charges. Actually, what happens is that continuous partial discharges lead to a problem known as digital memory, which reduces the accuracy of the power gauge of the device. Therefore, you might want to allow the battery to discharge and then put it on charge. This process will recalibrate the power gauge.

Don’t Discharge it Fully

If you discharge a lithium-ion battery below 2.5 volts, the built-in safety circuit opens to stop the flow of charge. As a result, the battery looks like it has no charge. In this case, you can’t use the original charger. In this case, you need to use a battery analyzer that features the boost function to recharge the unit.

Aside from this, it’s not a good idea to recharge a deeply discharged unit if you have stored it for a long time like several months.

Store in a cool place at 40% charge

I had an additional battery for my laptop but it wouldn’t do better than the original battery. The reason is that the battery was stored fully charged. In this case, the oxidation rate of the battery was at its peak. It’s better to store this type of battery at 40% discharge in a refrigerator.

Computer Parts Online

When personal computers first entered the mass market, building a computer was an arduous and risky task. Getting the right computer parts was also difficult and without a guarantee. Putting the whole thing together was a risk because of the newness of the product as well as the absence of expert knowledge. But over the years, the market has understood the process of computer assembly and the heavy savings involved in making your own computer (you basically save on the branded company’s professional service charge for putting the computer together for you).

Customers are able to find everything needed to build a computer on the Internet. If you want to assemble the whole system at one go, you can get a barebone computer system and keep adding on later. Using quality but cheap computer parts is the key trick behind assembling computers.

There are thousands of cheap computer parts on the web today. A quick check list of the main components you need to build your computer is –

  • CPUs (Processors)
  • Hard Drives
  • Graphics Card
  • Monitors

You can find any of almost all of these computer parts in Internet individually. Cheap computer parts are easy to find and pay for securely over Internet. There are also many sites and services that help you build these types of computers on a professional basis and get you started. These sites help you step-by-step through the process of building a good quality computer using cheap and high quality computer parts – often with illustrated instruction guides to show you how to put your new computer together.

Bitcoin Security Tricks

Use a Reliable Exchange Service

Web wallets are risky as hackers use them to gain unauthorized access to people’s money. If you really have to use one, make sure you use a reliable exchange service. Once the exchange transaction happens, make sure you transfer the coins to your own wallet right away.

Don’t allow open access to your Wallet

According to Joe Steward, you should not allow open access to your Bitcoin wallets. If an employee accesses your wallet and makes a transfer to a wallet they have access to, your money will be gone. To deal with this problem, you can use sub-wallets.

Use Separate Wallets

Often, Bitcoin wallets that are connected to the web all the time are prone to network-oriented attacks. So, it’s a good idea to use offline wallets instead. Actually, what you need to do is keep your digital money in the offline wallets. As soon as you get a big amount of money in your online wallet, make sure you transfer it to your offline wallet as soon as possible.

Store Your Keys Offline

It’s a good idea to store your private keys on an offline computer, which will help you keep hackers and malware at arm’s length. After all, you want to keep the system as secure as possible.

Use a Dedicated Hardware

It’s better if you use a dedicated USB key to transfer data between two computers. Again, it will protect your data from potential viruses and hackers.

Use Linux for added Security

If you are looking for the best way to move data between two computers, you may want to use a USB drive. For this purpose, the most secure system is Linux as it is very good at fighting USB-based threats.

Create Backups

You will lose your Bitcoin or wallet if you end up damaging your computer. So, it’s a good idea to create a backup of your wallet someone else. Ideally, you may want to make several backups and store them in different locations.

Benefits Of Visual Inspection Systems

Many benefits of the visual inspection system are inclusive of the increase in uptime, improvements in production, as well as a reduction in the expenses. These types of systems also make it possible for the companies for carrying out the entire inspection of the parts for the purpose of quality control. This also guaranteed that all of the products will satisfy the requirements of the customers. If one wants to enhance the efficiency as well as the quality of their respective industry, with the help of a visual inspection system one can do so with ease.

These types of visual inspection systems are out in the market at competitive prices, and there is a wide range of them available on the market shelves. One can select out of these, according to the types of requirements and needs that they expect from it, along with the quality. The unique features that are present in amongst most of the visual inspection systems are plug and go configuration, quicker image updates, automatic detection as well as faultless integration of the data, filtered views of the image, a full display, colored images, as well as views that are in the form of about nine systems of vision, however, this is not the end to the less, there is more coming.

These kinds of inspection systems are quite a hit in the industrial sector, this is due to their efficiency, repeatability as well as a knack for accuracy. They are complicated & are inclusive of numerous variables which affect the equipment which requires to be put into operation.

Other advantages that one will come to experience after the purchase or after making use of the visual inspection systems, as well as the visual inspection machines, are inclusive of the following – The visual inspection machines are capable of being able to adapt accordingly, and while executing this process they are quite quick to adjust and are able to do so with ease in accordance to the various surfaces and products. The visual machines of inspection can also be programmed, as well as monitored with close inspection, this is another added advantage. The best part is that these systems and machines can work for about a day that is an entire 24 hours. These machines also have a higher speed of inspection, and this is the sole reason that they are preferred over human inspectors. There is also maintenance of the consistency during the process of inspection.

Advantages Of Cloud Based IT Infrastructures

Flexible:

If you have a growing or fluctuating business, this would be the ideal aid. When needs increase, it is smooth to scale up the cloud capacity. You simply need to draw into the remote servers of the services you need. Again, you can scale it down because it is flexible. This also makes CIOs and IT Directors think that operational agility is the driving force of cloud computing.

Saves Money:

After flexibility, saving costs in one of the advantages of cloud based IT infrastructures. Business, irrespective of their size, exists to make money and keep capital and operational expenditures low. If you don’t use cloud computing for your business, chances are that you are spending more than you need to. With lack of on-premises infrastructure you can reduce the operational expenses in indirect ways, like air conditioning, power, administration expenses, etc. You simply pay for what you have used and then disengage when you’re done. You don’t need to add IT capital for this. If you feel that only large businesses can afford cloud computing, then that’s a misconception. It is one of affordable alternatives to opt for!

Reliable:

Internet makes cloud computing a managed service platform, and way more reliable than in-house IT infrastructure. The services we choose usually opt for a ‘Service Level Agreement’, for assuring all time availability. This gives an opportunity to have IT resources at all times, and with minimal failover mechanism. Only if your server fails to connect the application or service, you might lose access. However, if you can shift into a new server, you can start all over.

Manageability:

With cloud computing, we have access to easy IT management services. These are maintained through the central administration of resources, SLA backed agreements and vendor managed infrastructures. The IT infrastructure keeps updating, and the service provider maintains the resources. It gives you access to using an application or software through the internet. Alternatively, you don’t have install and keep updating it. SLA provides guaranteed delivery, maintenance and management, and keeps our worries away!

Strategic Edge:

Computing resources help us stay at par or go above our competitors. The time you would have spent for IT procurement, reduces. You can deploy critical applications which provide business benefits without spending upfront and save time. With the advantages of cloud based IT infrastructures you can forget technical issues and only focus on main business objectives. With saving time and reducing software hassles, you are catered with quicker and safer IT usage.

Identifying Mule Accounts

Today, mule recruitment is carried out in the internet by using scam. Fraudsters will send a false email about job searches saying that the victim’s resume was reviewed and that they are suitable to work at home. Due to the fact that the economy is rough and it is an opportunity, victims will take the bait. In the next e-mail exchanges, victim will sign fake paperwork and receive instruction for his assignment. Sometimes mules will be told to accept funds from the compromised accounts, reshipping of goods that are bought using other person’s credit card or even receiving the money.

Soon the fraudsters stumbled upon a problem, when potential recruits are asking about the company website. To fix the problem, fraudsters even built their own website as the front of their activities and candidates can view the site and see the vacancies. They made it look like a legit company by listing current employees and their jobs; details about their work and others.

Online mule recruitment has changed the way fraudsters operate because they don’t need a physical presence in that country so that they can recruit potential mules. Since he is doing his recruitment online, he can further increase the number of mules to increase his profit. It has become a challenge for many law enforcement agencies and incident response teams of industries because the mules thought that they have legit jobs. Sometimes, even mules become victims as well.

Sometimes there are places where online recruitment may become a problem, thus fraudsters will still recruit mules in real world. Sometimes, these mules can be accomplices who know that they are working with fraudsters and they can open multiple banking accounts. Another type of mule is what police call as the vacation or tourist mules; mules who are flown to different country and opens accounts in certain banks for their operation.

Somehow it is difficult for banks to stop a mule in opening a banking account because mules can be like any other regular person who is trying to open a bank account. However, it is still possible to identify a potential mule and stop them before they make any wrong mistakes that they will regret. Since mules can either be accomplices who are trained liar or unwitting victims who are too willing to make money. Identifying the first one can be difficult but the second one is not.

Identifying unwitting mules can be very easy by asking simple question before they can open bank accounts. It is the same as security screening found in airports, where weird sets of questions are asked; questions that are not designed for liars but for certain individuals who were duped and place into a particular situation.

For example bank employees will ask the individual whether someone else told him or her to open a banking account in this bank; or asking if opening this particular bank account is related into a particular job offer he or she received on the internet or even in the real life. Or any other questions that would raise an alarm for the bank, but it doesn’t mean that the employee can truly assess if that person is a potential mule or not. In fact the answers will be recorded and opening the bank account will be put on hold until further results from the investigations made by the incident handling or security team is available.

Basically, banks do not need to perform additional special training for their employees, a simple information campaign regarding new procedures will do. Customer education is really not that important at all, but it won’t hurt the bank if they will try like giving away fliers or posting ads that explains the danger of mule scams would help. Instead, banking clients and the public will appreciate the information given by banks and can help deter frauds in recruiting more mules.

Build Digital Commonplace Software

The idea of a digital commonplace system has not escaped people. In fact, a number of companies / service providers have actually tried to deliver a solution using their own technology – Evernote being the most recognizable.

The problem with the current attempts at providing a “digital” commonplace is they are just taking the “note” taking aspect of a “commonplace book” and applying it to the digital medium. You’re essentially able to store more information in a variety of different ways, stored in a “cloud” server online.

There’s nothing wrong with this, but a “real” digital commonplace needs more than just notes. We have the capacity – and potential – to create something truly remarkable… and people mostly don’t see it. For this reason, I have committed to explaining how a “digital” commonplace should work…

  1. Systems
    By far the most important element to a digital commonplace system is the way it’s able to manage systems (rather than just notes). Specifically, by having an interface through which a user’s data is able to be put, it could give them the ability to “track” all aspects of their lives – allowing them to focus on the projects they actually want to achieve. The big mistake most people have been making with their interpretations of a “digital commonplace” is to provide the most basic level of interactivity. What’s really required is a way to manage the systems that someone may have in their life – essentially allowing them to focus on improving and developing said systems (for the betterment of their overall life).
  2. Scheduling
    Alongside systems, scheduling also needs to be introduced. This will essentially provide users with the ability to create specific systems / results / data-management at particular times throughout the week / month / year. For example, perhaps they’d want to do a “year review” – this would be possible by scheduling a “review” system to run every year. On a technical level, this is handled by using a daemon – the equivalent of a cron job. Basically, it allows users to utilize the timing afforded by an “always on” system (cloud) to provide specific functionality for their lives.
  3. Interactivity
    Finally, the ability to interact / interface with other people. What was lacking from *any* of the online system that could even be considered as a broach to the “commonplace” ideals of the past is the ability to interact with others (both in the capacity of developing new systems and in sharing results / data from their present ones). To this end, any digital commonplace in the future really needs to have an interactive element, whereby users are able to connect with each other and have a way to “share” the various objects they are tracking in their commonplace.

Ultimately, what this means is that we’re looking at developing a system which focuses on integrating API’s into a centralized “dashboard” type interface.

However, the dashboard itself is not what you’d expect. It’s not a 2D boring interface – it’s an immersive application designed around particular scenarios… from being in ancient Rome to a future sci-fi city on a distant world.

The point is that the digital commonplace – at its core – needs to be able to inspire the imagination of anyone using it. This not only means that you need to be looking at embodying a particular ideal with the system, but that each time the user is able to upgrade it etc, they’re able to essentially get a large number of different options to help further their development.
