I currently have a Lenovo G560 with a BIOS password that I do not know of and can't contact the previous owner either to see if they know it, but I am requesting if there is a way to remove it. I just get an error message saying the system is halted after entering the password wrong too many times and that's it other than it also saying I said the wrong answer 3 times and blah blah blah. Is there any way to remove it other than replacing it? I really need it because I can't access all my RAM 8GB (2.93 usable) and also want to use a virtual machine. Thanks! Update: CMOS battery cannot be removed because it is built into the motherboard. I also can't shorten out the CMOS because I can't find the points to shorten it out. I also can't cut power to it because there is nothing that can cut the power between the battery and the CMOS. Although, I am currently contacting the previous owner for the BIOS password. I might end up buying a new motherboard to replace it.
