It keeps overheating and then shuts down - Toshiba Satellite Pro L300 Notebook

Answers :

Overheating usually happens when the fan is not coming , therefore when the computer overheats.Or the fan is not cooling enough and computer is overheating. This may happen because of dust and dirt, because of damaged fan bearing or motor, because of scarce adherence with CPU surface.

Monitor computer temperature using a software, check if Fan is coming up when temperature gets critical.

If fan comes up but does not cool enough, then replace the fan, it is not efficient anymore because of a bad bearing or dust. ~Also ensure that fan is well mounted, if fan has poor contact with CPU surface , cooling will be poor.

If fan does not come up, and critical temp is not detected, then the sensor on motherboard is bad, this is very uncommon. When this happens the problem is usually related to system or power settiings , rather than overheating.

If fan does not come up and temp is critical, then fan is faulty, replace it.

There are also more than one fan on many laptops, check that one of the fans (CPU fan, video fan) is not completely ded, and therefore cause for the problem.

By using the software below you can also find out if the problem is really overheating. If temperature results within normal range, then usually it is not overheating.In that case test systtem and check power saving settings.
