Random Shutdown - HP laptop

[IamPritesh]

The Laptop shutdown randomly. Sometimes in few seconds as soon as you start and at then there are occasion when it works fine for an hour and then shuts down.So there is no fixed time ..it can few seconds, few mintutes of few hours. Most the of the time it shutsdown within a minute ..even in BIOS menu.


Model Name : HP Pavilion Notebook - 15-ab029tx

What does these symptoms point to ??

Remove battery and try again.

Tried it . Doesn't changed anything. Even replaced the cmos battery

Sounds like a heat issue to me.
Or maybe a bad solder connection somewhere. Try to flex the laptop in all directions a little bit while on.

Re: Random Shutdown - HP laptop

very difficult to say what is the fault in such scenario as symptoms are not constant. as@kvntm has said may be bad solder joint, corrosion somewhere on the board. Can be 'coz of bios also, so do flash a tested bios. In some cases it is caused by a bad sio chip as well.

Thanks for your valuable inputs
Can BIOS cause such issue? I thought it is only responsible for the startup ..

Re: Random Shutdown - HP laptop

Last time I had this problem with HP, I reprogrammed BIOS, which did not help and then removed battery, which did help. Maybe it was somehow the combination of these two actions.

In your case did it work for few hours occasionally ?

Did not test much, usually in a few minutes.

Re: Random Shutdown - HP laptop

If it was a bios issue it won't shut down randomly or after hours. Someone on this forum pointed out that intel cpus will shut off if the me region is incorrect/corrupted but that will happen after 30 minutes.

Just give the laptop a few flexes or shake it a little. This problem is very hard to pinpoint. I'll bet for a bad solder connection that fails due to heat expansion.

Mb marking?? It has to do with thermal protection of SIO.

Re: Random Shutdown - HP laptop

Review the voltage readings to ground from the thermal sensor.

What is the voltage to ground for PM_THRM# pin ? If this voltage is LOW, then this sensor is alerting the logic board that the temp is too high so shut it down.

Meter in DC volts mode -> red probe to PM_THRM#. Black probe to ground.
