|When I hover my mouse over the power icon in the taskbar, I perpetually receive "28% available (plugged in, not charging)". Yet, as soon as I disconnect the power cord (with battery still attached), my laptop powers off. Under my monitor, the battery button keeps flashing orange.|
I'm running Windows 8 on a Lenovo T500. My low battery levels are set to 15% and my critical levels to 7%.
This problem arose out of the blue. It was just sitting on my desk on battery power and then suddenly powered off.
Lastly, this may not be related, but when I first took a look at my battery to figure out why it suddenly powered down, the laptop was unusually hot, something I've never noticed before. I'd just dusted my peripherals recently too.
When I run my laptop w/o the battery in (cord only), I still get the same readings on the taskbar's power gauge, "28% available (plugged in, not charging)".
This leads me to believe that there is a problem that would not be resolved if I simply bought a new battery.
