Answer» I've had my current laptop battery for about 3 years. Now, I can't take the computer off the AC adapter without the computer saying the battery was low and then shutting down a few minutes later. I bought a new battery. I got it in the mail yesterday, put the new battery in and plugged the computer into the AC adapter to charge overnight. When I woke up this morning, I UNPLUGGED the AC adapter and the computer shut down. What's going on?? What's wrong?? I have the same problem with one of my experiential laptops. I think it MAY be a hardware problem. What model is your Laptop?What laptop mfg and model do you have? Did you buy an oem battery or a third party? Unless there is a re-calibration scheme required for your laptop, the suspects, of course, are the new battery or the power adapter. Power adapter works to power the laptop, therefore, I would assume that you got a bad battery; assuming that there is no procedure to follow to replace the battery.No help to you but - my rather ancient HP laptop (Pavilion xl328), which I bought used - had a pretty ''tired'' battery so at vast expense bought a new one. Was not overjoyed when I found that the improvement was way less than stellar. I had EXPECTED something like a 2 hour session on battery but it seems to still be very poor. Maybe not quite as bad as yours but far from impressive. Odd tho, as I have seen numerous instances of folks on air flights using a laptop for absolutely ages - obviously on battery.Quote Odd tho, as I have seen numerous instances of folks on air flights using a laptop for absolutely ages - obviously on battery.

Li-ion batteries have a self-monitoring circuit - I don't know why the laptop manufacturers can't tie-in to that and get an exact readout of remaining capacity instead of the highly inaccurate (imo) 'battery' meters used.
