Why My Laptop Battery Is Not Detected. One or two cells in the old battery pack have failed. Process for calibrating the battery.
It may be a counterfeit or an aftermarket replacement battery. For this you must turn off the device and give a 100 charge. If the battery IS recognized but the adapter isnt.
Change the DC power jack in the system.
Sometimes it just says the battery is not detected - and upon unplugging it the laptop remains on. If you lose power in the middle of updating the BIOS you can serious damage you computer. I attempted to flash the bios but when it started to run it asked. Press the Win key and R key together type appwizcpl in the dialogue box and click OK to open Device Manager.
