MacBook powers off if not powered via AC?
MacBook will only stay on if plugged into wall outlet. When running solely on battery, it will randomly power down. If it is able to be rebooted, it resets clock to Jan 1, 2000 and time to 12:00. It also doesn't recognize the wireless network it automatically connects to. Can this be solved by installing new battery? Based on other forums, it could be the logic board? Is the expense worth fixing or buying new computer. MacBook is from 2009.
Is this a good question?
