Acer One 10 battery discharges overnight

I've used an Acer One 10 S1002-145A, with Windows 10, for about 15 months. Now, overnight with power-off, the battery discharges very rapidly, and can reach 0% after 2 nights. The unit does fully charge and operate properly with the AC charger. I would think I need to replace the battery--however, I see no instructions or physical access to replace the battery. Is this a situation of needing to ship the unit to Acer or buy a new unit? I will contact Acer support later this week--I just wanted to ask the Community first.

(NOTE: I realize the Acer One 10 is not strictly a Switch Series unit, but I didn't see another suitable choice among the Forum boards.)

I have concluded that the battery is operating properly. I examined the Windows system
logs, and observed that the unit was going to sleep instead of shutting down. I then forced a
shutdown using the command prompt "shutdown /s /f", and verified that the battery did not
drain over several hours. I also tried the hibernate option, and the battery did not drain for
hibernate. I am continuing to experiment with the power management settings to correct the
shutdown->sleep issue, but I am confident that the battery is OK.

I thank laurent_14 for requesting the Wear level. The low wear of 9 suggested the
alternative situation of the power not really shutdown.

Hello,

First could you check the Wear level value in using HWMonitor zipped version (no installation)?

With the unit operating from the AC charger, the Wear level is 9% and the charge level is 100%.

Also, is it possible that the problem is that "Power Off" is not really off, as opposed to a defective battery?

Thank you.

Just an added note that Shift+shutdown also creates a proper shutdown, similar to Command Window "shutdown /s /f". The normal shutdown continues to sleep, with battery drain.
