    Hi guys,

    First post so go easy on me.. I'm trying to fix my friends Asus notebook which won't boot up. My main problem is that it won't let me access the bios and I'm using the right bios key. So, my main question is, how do I reset the bios? I stripped it down looking for the cmos battery to reset the bios from there but I can't see one. Does anyone know if this board actually has a cmos battery, if so where's it located and if it doesn't, how do I go about resetting the bios?

    Thanks, Stevie..
