Self-diagnosis laptop

It is enough to type in a line of the search systemthe words "laptop diagnostics", how many 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 bold statementssome service centers that independent diagnostics of the laptop at home is almost impossible, since it requires the use of special tools and instruments. In fact, this is only partially true. To perform repairs that require interchanging microcircuits, controllers and other electronic components, one can not 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 laptops,having made a decision to contact the service center where the diagnostics of the laptop should be performed, thinks about the potential danger of such an act. And completely in vain!

Although there are repair shops in whichcheck performed at the client, most work on the principle of "today gave - tomorrow took." This is quite understandable if we take into account the number of those who want to form the most real queue. Now imagine that the laptop's hard drive stores family photos from the "nude" archive. Leaving such a computer in someone else's hands, it is quite possible to expect the early appearance of such pictures in the public domain on the Internet.

Security of access codes to banking websitesOnline services that are 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 electronic friend systems independently.

Let's move on to practice

We have already indicated earlier that the assertion that it is impossible to independently verify is only partially true.

There are two types of diagnostics: software andhardware. 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, remove the housing cover and inspect the internal components, including cleaning them.

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