content: Really? Does it work in Windows? Sounds like a hardware problem, but you can check BIOS. You should be able to shut down the computer all the way and when you turn it back on (when the Asus logo appears) press F2 a couple of times. (can be another button like F10 or something, but I think it's F2 on Asus computers) This would get you access to your BIOS, and checking the BIOS will make sure that there isn't any software preventing it from charging. Check to see what it says about your battery. I did come by someone with a similar problem ( http://ubuntuforums.org/archive/index.php/t-2176915.html , where they had problems charging it after installing linux. ) It was solved by letting the battery completely discharge and THEN connecting the charger.  There is also advice about disconnecting the battery and powering the laptop back up. I suspect that this causes the battery controller (in the laptop) to reset itself so it starts the calibration process over. For some reason this then allows the battery charging circuits to start back up. Sounds like a fail safe to me. I found one solution you might try. Just going to quote it, it seemed to solve the battery problems people had:  The solution:   Remove the T5 Torx screws from the bottom to access the battery.   Remove the battery.   Plug in the AC power and turn on the laptop.   Shutdown the laptop and put the battery pack back in and you are good to go.   The battery will NOT reset by just taking the battery out and re-seating it. I've tried, it doesn't work. You have to cycle the AC power first.  The problem does not seem to be related to Linux, other people have similar issues when installing Windows. I am not a hardware guy so I can not answer what might be the issue, but here you have some things you might try out. Hopefully it will solve your problem.
