Acer A515-54-749U shows battery at 64% available (plugged in), but it will not run without the charger plugged in and turned on. It behaves as if the battery is dead flat. This is using a brand new battery. The old battery was doing a very similar thing, so I replaced the battery, with no change in behaviour.

I have deleted and reinstalled the 2 drivers under Battery in Device Manager, and tried to update the SBMBus - 02A3 in system drivers. "Best driver is already installed"

I have unplugged the charger/power supply, held down the Power Button for 30 seconds, and used the Battery Reset pin-hole for 30 sec with a paper clip.

I still have the problem - Laptop will not start unless the charger is plugged in, and the laptop dies immediately the charger is disconnected. Using the new battery or the old battery.

Running Windows 11, up-to-date. BIOS ver 1.16

What should I do to fix this issue?
