I have a Lenovo thinkpad 12 and it no longer charges properly. I plug in the charger and the outlet is fine but when I try to turn on my laptop it gives me the error message about critical battery. I have tried the take the battery out and hold down the power button for 20 seconds that I saw elsewhere on this forum but it did not work for me. Any other troubleshooting strategies I can try in order to fix it? I have had the laptop for 1.5 years now.

Figured out that the laptop will nharge for a few seconds when I first plug it in then the red charging light goes off. If I move the laptop around while plugged in the red charging light will sometimes blink as well
