Plugged in, says its charging but its not


Dec 29, 2014
My Toshiba Satellite C55t-A5287's battery is not holding a charge. It was last night but now its not. When my computer is plugged in it says that its charged at 54% but when I unplug it from the adapter it immediately shuts off. I already tried unplugging all cables, taking the battery out, and pressing the power button down for thirty seconds. I also tried going to the device manager and uninstalling the ACPI Compliant Method Battery and then scanning the hardware for changes. I don't know what else to do.
