i followed the guide over at arch wiki, but im having serious power issues.

currently i have my charger unplugged and it says that its charging and 1hr 58 min till 100%. battery life is abysmal

may or may not work, worth try..

Turn off your laptop, unplug all wires, remove the battery, and hold the power button for thirty seconds. Afterwards, reattach the battery and connections.

turn on and check
