Self-diagnosis laptop

It is enough to type the words "laptop diagnostics" in the search engine's line, as a lot of pages will be issued from Russian-speaking companies, private traders and small firms that offer high-quality performance of this service.

Well, if you take into account the prevalence of portable computers, it is clear that now it is in demand.

It's amazing to read the bold statements of some service centers that independent diagnostics of the laptop at home is almost impossible, since it requires the use of special tools and devices. In fact, this is only partially true. To perform repairs that require interchanging chips, controllers and other electronic components, it is really necessary to do without special equipment, but simple diagnostics of the laptop will require only three things from the owner: a blank CD or flash drive, a program for testing components and about an hour of free time . Quite a bit, is not it? That is, it is possible to independently diagnose the laptop.

To do it well, do it yourself

Few of the owners of portable computers, having decided to contact the service center, where the diagnostics of the laptop should be performed, is thinking about the potential danger of such a deed. And completely in vain!

Although there are repair shops in which the check is carried out at the client, most work on the principle of "today gave - tomorrow took". This is quite understandable, given the number of people who want to form the most current queue. Now let's imagine that the family's photos from the "nude" archive are stored on the laptop's hard drive. Leaving such a computer in someone else's hands, it is possible to expect the early appearance of such pictures in the public access on the Internet.

The security of access codes to online banking sites located in cookies (browser files) can also be affected. And in the presence of unlicensed software there is a theoretical probability that it will take a long time to explain where it came from on the notebook storage device.

Thus, it is much easier to verify the efficiency of all the systems of the electronic friend yourself.

Let's move on to practice

We have previously indicated that the assertion that it is impossible to independently verify is only partly true.

There are two types of diagnostics - software and hardware. The first one is used if you can turn on the system and download programs. The second requires disassembling the case and working with some components. In particular, you may need to remove the battery, check the power cord and connectors, remove the housing cover and inspect the internal components, including cleaning them.

For software testing, you need to download and write to the media the following programs: OCCT Perestroika (CPU and power supply test); 3DMark (testing the video subsystem); Memtest86 + (definition of possible faults of memory modules); Victoria (hard drive); Battery Mark (laptop battery diagnosis). Each of them can easily find the documentation, so with the start, as a rule, no problems arise. By checking the operation of components with the help of the specified software, you can easily determine the current state of your irreplaceable assistant.
