My Acer Aspire 5542G takes 3 or 4 'switch on' attempts to start each day. I know the Cmos battery is not working properly because I lose time if the laptop is off for more than 2 days. The problem is: Acer Cmos batteries are extremely difficult to replace and I don't want to go to that expense if it won't help with the start-up. I can live with an 'incorrect' clock - it's easy to fix.
Can a faulty Cmos battery cause a laptop to not start up
