VBAT Battery monitoring (Asus Rampage VI Extreme Encore)

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

It should be able.  What motherboard do you have?

On that motherboard VBAT monitoring should work accurately.

Sur cette carte mère, la surveillance VBAT devrait fonctionner avec précision.

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

It means AIDA64 may use an incorrect sensor register to measure VBAT.  Can you make test runs with both a depleted and a good battery?

I reassembled the PC and I no longer have the old battery, sorry
