The battery works and charges perfectly fine on another laptopĪlso suggests that the problem is elsewhere, btw it would have been helpful had we known this latest info from the start It does the same if I use someone else's charger. My laptop automatically turns on the led lights when the charger is connected without the battery but doesn't go through to login, the screen remains black and the fan runs for a couple of seconds then it goes off.Īs the present battery charges on another computer and the behaviour is the same with a known good charger you are now looking at internal hardware failure, for example, the computer starting and then shutting down when on mains power could suggest a system short circuit, if it was due to overheating you would at least get a BIOS screen and the notebook would behave the same when only the battery was in use.
