    Hey guys, I've got a problem.

    I've just flashed my T410 to the latest BIOS version (1.34 I), but now the laptop does not recognize when it's plugged into the AC. When I plug the laptop in to the AC, there is no "beep" that usually comes on that tells me that the battery is charging, the green battery icon does not light up on the outside, and Windows thinks I'm always running off of the battery. The battery still charges at the normal rate, however (Hopefully the battery is not being OVERCHARGED but I think the battery's circuitry prevents this).

    Obviously this is the result of a bad BIOS flash, the question I have for you guys is how to reflash my BIOS. Lenovo's BIOS utility does not allow me to flash it if I'm not plugged into the AC, and since the laptop is unable to realize that it is in fact plugged in, I am unable to flash the BIOS!

    tl;dr Anyone have any ideas on how to circumvent these safety features and reflash my BIOS? Thanks.

    Call lenovo. Chances are, you'll have to send it in anyway.
