Yesterday my battery was working fine (for an old computer). It could sustain a normal usage for three hours at least. Today I have the following symptomas:
- I noticed that it didn't charge, even though it is written "plugged, charging". The level stays at 61%.
- If I unplug the laptop, it shutdowns immediately and brutally, just as if there was no battery at all in it.
Just before I noticed the problem, I changed the power plan from balanced to powerful, then to balanced again.
I believe the battery is not the problem, or at least it is not the normal old battery die-out because it is so sudden. Not a slow death. Do you think it could be some settings that I changed wrongly?
The computer is a Sony Vaio VPCSA from 2012. The battery is the original.
Can I conclude anything from it? Is another part of it important?
I also checked the VAIO control center for battery health, and got all green:
Based on @DrMoishe Pippik answer, I followed the Vaio troubleshooting checklist. What solved the problem was to remove and replug the battery. I don’t know if this reset some parameters, or if it had moved or if there was some dust, but now it’s working again. Long life to my old Vaio!
