820-3662-a Shuts down after 10 minutes

[iClub]

I have cleaned the ME BIOS region, the plate measurements are correct: PPBUS 12.6v ; PP3V42 3.48v; ALL_SYS 3.3; PLT_RST 3.3v;
Can you help me in this case please ?

You should test known good battery, to discard battery issue.

Can still be a problem with FDMF6808 chips.
Some software mods can disable CPU sleep states (Cx); you can then see if still turns off with battery.

It is that same defect.

Search and try that mod.
Or put new FDMF6708 chips; from Mouser, or other serious store...
