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

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

Thank you.  We've double-checked it, and according to the information available to us, AIDA64 uses the right sensor register to measure VBAT voltage.  Did you see the VBAT voltage drop to under 1 Volt in the UEFI Setup?

I don't have the VBat voltage in the UEFI BIOS (or I have never seen it)

Thank you!  It may mean the standard VBAT register in your sensor chip is not actually relevant for VBAT measurement.

Merci ! 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" ?

In general, no, that's not the case.

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