Sony VAIO GRT170 laptop fans wont run.

\015 Hello,\015\012ive had this laptop for about 5 years now. both fans will not work now and the laptop with shut down after about 3 minutes. i know the fans are not the problem, because they still run off of a 9v battery. i was wondering if there is anything i can do without replacing the motherboard.\015

Answers :

Overheating usually happens when the fan is not coming , therefore when the computer\015\012overheats.Or the fan is not cooling enough and computer is\015\012overheating.
\015\012\015\012\015\012
\015\012\015\012\015\012Monitor computer temperature using a software, check if Fan is coming up when temperature gets critical.
\015\012\015\012\015\012
\015\012\015\012If fan comes up but does not cool enough, then replace the fan, it is\015\012not efficient anymore because of a bad bearing or dust. ~Also ensure\015\012that fan is well mounted, if fan has poor contact with CPU surface ,\015\012cooling will be poor.
\015\012\015\012\015\012
\015\012\015\012If fan does not come up, and critical temp is not detected, then the\015\012sensor on motherboard is bad, this is very uncommon. When this happens\015\012the problem is usually related to system or power settiings , rather\015\012than overheating.
\015\012\015\012\015\012
\015\012\015\012\015\012If fan does not come up and temp is critical, then fan is faulty, replace it.
\015\012\015\012\015\012
\015\012\015\012\015\012There are also more than one fan on many laptops, check that one of the\015\012fans (CPU fan, video fan) is not completely ded, and therefore cause\015\012for the problem.
\015\012\015\012\015\012
\015\012\015\012By using the software below you can also find out if the problem is\015\012really overheating. If temperature results within normal range, then\015\012usually it is not overheating.In that case test systtem and check power\015\012saving settings.
\015\012\015\012
\015\012\015\012\015\012Here is the software to control your fan and temp. sensor state:
