Hi everyone, I am running Debian Linux on a Dell Precision M4700 i7 laptop. When the power cable is unplugged, the computer shuts off seconds later. However the battery percentage shows 100% and a BIOS diagnostic of the battery reveals no problems, not End of Life or anything. I can't do a battery calibration, as the computer shuts off after moments of unplugging. This started after I replaced the factory provided battery (EOL) with one I bought from eBay. It was working fine, until it began shutting off when the power cable is unplugged. It doesn't work when the hard drive is removed, either (shouldn't be an OS problem). Thanks for reading, I greatly appreciate any feedback.

Ok, thanks. I suspected this was true but thought there might be slim chance of a systematic change I can do. I contacted the seller of the battery to request a refund.
