Possible errors

To deal with the problems a laptop will have any user, so it is better to establish in advance how to spot each of the errors leading to disconnection.

Clogging the system with dust

Heating of laptop is in the process of functioning can be explained by simple laws of physics: electric current passes through the wires and generates heat. The higher the frequency the processor, the more powerful will be the heat.

In this connection, modern laptops have:

  • strong built-in coolers;
  • special ventilation holes in the bottom of the housing;
  • additional stand for cooling.

However, if the ventilation gateways litter clogged, and the blades of the cooler dust accumulates, the cooling system ceases to be carried out properly, resulting in:

  1. when you run heavy games and programs back PC becomes hot, after which it abruptly terminates;
  2. when you disconnect the laptop doesn’t make any noises, does not give blue screen and does not display any inscriptions;
  3. in 10-15 minutes after startup computer freezes and the front panel heats up, the fan starts making a lot of noise;
  4. just 30-60 seconds of operation the temperature of the system, which can be viewed in the BIOS, approaching 80-90 degrees.

The solution here can be only one: full hull cleaning from contamination.

Viruses

Malware can enter in PC when user visits specific sites, attaches to a laptop infected external storage media or open letters of questionable content.

Disabling a portable computer in contact with the virus may manifest itself as:

  1. on the screen the message «Windows is blocked», after which the device terminates;
  2. the operation of the programs stops and displays a blue screen;
  3. when you run any browser window appears «Computer will shut down in a minute NT:AUTORITET/SYSTEM».

Certain types of modern viruses cause the processor to operate in emergency mode. Which results in a few minutes to heat up the body and restart.
