tistou77 Posted June 24 Posted June 24 Hello Can Aida64 correctly read the battery voltage ? My PC was having trouble saving BIOS settings, Aida64 showed a battery voltage of 3.12v I removed the battery, and the multimeter showed 0.76v Thanks Quote

That's not the case, I did several tests, and it clearly indicated 3.12v for the faulty battery (~0.76v on the multimeter) The new battery fluctuates between 3.16 and 3.18v Quote

Can you make test runs with both a depleted and a good battery? Quote

tistou77 Posted June 26 Author Posted June 26 When I tested the new battery, the multimeter showed 3.23v (or 3.27v, I don't recall exactly). In Aida64, it shows 3.16v, if it helps Quote

Did you see the VBAT voltage drop to under 1 Volt in the UEFI Setup? Quote

Cela peut signifier que le registre VBAT standard dans votre puce capteur n’est en réalité pas pertinent pour la mesure VBAT. If this voltage isn't present in the UEFI BIOS, does that mean it can't be "properly read" ? Quote

tistou77 Posted June 27 Author Posted June 27 Ok thanks It's not a big deal, it would have confirmed to me that the battery was indeed dead, with the correct voltage. Quote
