I know there is another thread exactly like this but I was looking for some help troubleshooting the problem. I realize its most likely the motherboard but I was following a guide (I can't post the link since I'm a new user)and the guide is taking me through steps, such as disconnecting the bios battery to reset it, trying to see if I could solve the problem. I have a Lenovo Ideapad Z565. I took the entire thing apart but I cant seem to locate a bios battery or dip switch. The guide says to remove the battery and put it back in to reset the bios but Im thinking the battery in this model doesnt come out. Do you guys know if there is a bios battery or dip switch I can mess with that Im not seeing? Also, is it pretty likely that my motherboard is completely shot anyways? A dead motherboard isnt really worth replacing on a laptop right? Any help would be appreciated. Thanks guys.
