It is enough to type the words “laptop diagnostics” in the search engine line, as many pages from Russian-speaking companies, private traders and small companies that offer high-quality implementation of this service will be displayed.
Well, given the prevalence of portable computers, it is understandable that this is now in demand.
It is quite surprising to read the bold statements of some service centers that the self-diagnosis of a laptop at home is almost impossible, as it requires the use of special tools and instruments. In fact, this is only partially true. To carry out repairs requiring soldering microcircuits, controllers and other electronic components, you really can not do without special equipment, but a simple laptop diagnostics will require only three things from the owner: a blank CD or USB flash drive, a program for testing components and about an hour of free time . Quite a bit, isn't it? That is, independent free diagnostics of the laptop are quite possible.
To do the job well - do it yourself
Few owners of laptop computers, having decided to contact a service center where laptop diagnostics should be performed, think about the potential danger of such an act. And in vain!
Although there are repair shops in which the check is carried out with the client, most work on the principle of "today gave away - tomorrow took away." This is understandable when you consider the number of people who want to form a real queue. Now imagine that the laptop’s hard drive stores family photos from the nude archive. Leaving such a computer in the wrong hands, one can expect the imminent appearance of such images in the public domain on the Internet.
The security of access codes to online banking services sites located in cookies (browser files) may also be affected. Yes, and with unlicensed software, there is a theoretical probability that it will take a long time to explain where it came from on a laptop storage device.
Thus, it is much easier to check the performance of all electronic friend systems on their own.
Let's move on to practice
We have already pointed out that the statement about the impossibility of independent verification is only partially true.
There are two types of diagnostics - software and hardware. The first 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, dismantle the housing cover and inspect internal components, including cleaning them.
For software verification, it is necessary to download and write the following programs to the media: OCCT Perestroika (processor and power supply test); 3DMark (verification of the video subsystem); Memtest86 + (determination of possible malfunctions of memory modules); Victoria (hard drive); Battery Mark (laptop battery diagnostics). You can easily find documentation for each of them, so with the launch, as a rule, there are no problems. After checking the operation of the components using the specified software tools, you can easily determine the current state of your indispensable assistant.
