Thermistors exceeds critical temperature - HP Elitpad 900

[MartijnG]

Hi,

When i started my tablet HP Elitepad 900, i go out of nowhere this error: “One or more system thermistors exceeds critical temperature. System will shutdown in 5 seconds…”

I didn't change everything and it was running fine before. I cant start my tablet anymore, also in bios/boot option the system shutdowns.

Does someone know how to fix this error or where to look at?

Model: HSTNN-C75C
Motherboard: QPJ80 LA-8781P , SPS: 724353-001

Thank you!

Greetings,

Martijn

Does any point on the board of this tablet get hot?

I measure between 40 - 45 degree Celsius on a Hynix H9TKNNNBPDMR chip.
See attachments for pictures.

For what i know it's not really a critical temperature?

I tried to start-up with cooling spray on the hottest part (Hynix chip). But still the same error appears and system is not booting.

Can it be some kind of faulty temperature sensor? (Where to find that sensor?)
Or maybe some software lock (how to (factory) reset a chip?)

Hopefully someone can help me further
