So my 4.5 years old P751TM1-G decided to die this morning... When I press the power button it starts to bootloop:
Turns on for about a minute, black screen, no beeps, keyboard flashes in various colours. Then turns off and repeats.

* I have tried removing all 4 RAM sticks but no difference (was expecting a beep to complain about missing memory)

* I've removed the BIOS battery, tried holding the power button for 30 seconds with and without the BIOS battery and the laptop battery and with or without the power supply being connected. Tried the FN+D + power button for a BIOS reset but no luck...

Any ideas?

Does this sounds like a corrupt BIOS chip?

Can you boot into the BIOS and see what drives show in there

 

[geoiva]

How do I boot into the BIOS? Nothing happens on start up.

 

[Martinr36]

Normally press F2 or Delete as it boots

 

[SpyderTracks]

Have you serviced it since you've had it? ie repasted the CPU and GPU?

 

[geoiva]

The laptop doesn't boot so there's no F2 accessible or anything.
@SpyderTracks I've not serviced it, no.

 

[Martinr36]

press f2 as you turn it on

 

[geoiva]

@Martinr36 doesn't do anything.

 

[Martinr36]

So nothing happens when you turn it on at all

 

[geoiva]

That is correct

 

[Martinr36]

Sounds as though it's completely died 😔

 

[geoiva]

I think the BIOS is corrupted. What happens in that case?

I think the BIOS is corrupted. What happens in that case?

If you haven't serviced it since you've had it it's very likely burnt out. You need to repaste once a year to prevent overheating.

 

[geoiva]

Does that have anything to do with the BIOS chip though?

It’s likely the motherboard / cpu.

... so many months later and after pc-specialist have had the laptop for almost 2 months, the motherboard has been deemed un-repairable and there's no spare part available so my 2k+ 4.5 years old rig is now useless. What a disappointment :-(
