I have an Asus A42F-VX019D notebook. This problem happens after I update my bios. I have downloaded the right bios (Bios 409) for my notebook, but when I tried to update, Easy flash warned me that bios is not the same type. Because I'm sure it's the right one, I just update it. After update process reach 99%, my notebook suddenly turned off. And I cannot turn it on again (The power led doesn't on, which means total dead). Anyone know how to reset bios without turn on the laptop ??('Cause I can't turn it on)?? There are five led indicator on my laptop. Power, charging battery, HDD,activity, Wireless, and padlock symbol. Usually if I plug the AC cable when the battery is unpluged, the charging battery led wouldn't on. But, after this problem happens, the charging battery led is always on whenever I plug the AC cable or install the battery.
