Hey guys, I'm a Mac Shacker, but I recently pulled my old Asus M5N out of the closet to start using it again (need to run GMAT program with it). I haven't used for quite a long time so I plugged it in and started charging it, updating and defragging it (8 hrs ) After all was said and done, I unplugged it to take it with me to another room and it just shut off. Basically the battery won't hold a charge anymore. Does Windows have a battery meter checking tool? Or does anybody have any suggestions about bringing this thing "back to life"?
