Hello,
I have an Acer Revo One RL85, a desktop PC connected to the TV, and I get a CMOS checksum error every time I start the PC (if there's no power), otherwise if I restart it works fine, so I think the battery needs to be replaced.
I can't press F1 or anything else with my Bluetooth keyboard....
Acer told me that out of warranty, if it's indeed the battery... it's 170 euros because the motherboard needs to be replaced as everything is soldered.
Thank you in advance if you have a solution

Hello,
You can find USB (wired) keyboards for around 10 euros,
the Bluetooth should not work on booting the PC.
The battery is not soldered to the motherboard, you can change it.
I’ve never seen a motherboard where the battery was soldered.... but there's always a first time.
If that's all, you can simply reconfigure the date and time on your PC manually with a USB keyboard, every time you turn it back on.
