I have an HP laptop that has an old battery. The battery is working but lasts for short time.
However I don't need the battery as most of the time I am using it plugged. I tried to remove the battery and run but it does not run without battery. I purchased a new battery (not original, since HP stopped producing old batteries) but it does not boot with it (even it is the SAME 7.7V - 41W). I now returned the old battery and the laptop is working. Can I somehow remove the battery and run the laptop without it? (maybe plugging the power cable directly to input caple without going through battery?)
