I'm running Ubuntu 20.04 LTS on a HP 15-ac152. When I check the battery details using upower -i, I find
native-path: BAT1 vendor: COMPAL model: PABAS0241231 serial: 41167 power supply: yes updated: Sun 08 Aug 2021 18:42:53 BST (66 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 0 Wh energy-empty: 0 Wh energy-full: 33.1712 Wh energy-full-design: 41.61 Wh energy-rate: 0 W voltage: 12.702 V percentage: 0% capacity: 79.7193% technology: lithium-ion icon-name: 'battery-caution-charging-symbolic'So the battery's detected and ubuntu thinks it's charging, but it always stays at 0% on the battery monitor and when I unplug the machine while running it powers straight off so I think there must be no charge in there.
I tried turning the laptop off, taking out the battery and holding down the power button for 30s and turning back on, but this didn't help. So I also tried following the instructions here, which involves disabling the battery in the BIOS, but I had a look through the BIOS and I couldn't see an option to disable the battery.
Does anybody have any advice on how to disable the battery from the BIOS or elsewhere, or any other kind of method to fix/diagnose what's going on? I'm happy to buy a new battery if I need to, but I suspect I can reset something and get it working and I'd like to rule that out before spending any money.
