It is amazing what a little soldering or a few changed capacitors will bring back to life; I like to think the repaired unit may have even more life than the new unit as weak points have been located and attended to.

HI Subran,

You need to open it up and check. It can be bad filter caps, shorted diode and etc. If you do not have experience in electronics repair i suggest that you send to a repairer because inside have high voltage.

HI Samq,

Try use a fan to blow on the motherboard to see if it will shutdown. If no more shutting down then you know is the heat problem. Now try use your hand to touch on the board ics (make sure you have removed the static charge from your body first)ad see which component is getting very hot.

As for the laptop, if all the voltages are good then it could be the graphic ic problem which you need to replace.

HI Chief,

It can be bad ram, motherboard or even power supply. Sometimes it could also can be cause by virus (software).

HI Naitik,

From your description chances is high the power supply is the problem. It may be the problem of bad filter caps and you need to open the power supply to test it out with esr meter.
