My laptop can not came on but the fan and the power button LED came's on what can be the problem?

is make sure battery is charged i.e. the adapter is working and the connector on the laptop is not desoldered.

Hi, this is a mother issue, you must get tecnical service for

Reflow, Reballing, before your mother do not reponse any more.

I doubt there is battery problem, have you tried switching on laptop without battery and connecting through the laptop charger? most probable your battery is not taking the charge. so suggest you to disconnect the battery and try using laptop with charger then you'll find the problem.

my laptop is sony PCG-7173L. No thing display on screen and i even cant shutdown and there is no power led on power button and no sound of fan too....i cant go to advance boot option also..Please can any body help me...

That would leave the processor ic, usually most motherboards do not include that.

Hi

Before your computer running fine, you just remove the fan and heat sink, and fix properly.

1) Check your VGA cable both of side fix properly
2) Check your Monitor power button is switch on.
3) Remove your RAM and fix again.
