Temperature exceeds critical temperature - HP Elitpad 900

Hi,

When i started my tablet HP elitepad 900 (Model: HSTNN-C75C), 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?

Thank you!

Greetings,

Martijn

PS. i got electrical engineering knowledge/solder experience.
