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.
Thanks

Having to start your laptop repeatedly may corrupt your OS and cause wear to your HD.

A Cmos battery will cost you a maximum of $10 USD or 100 ZAR.

Hi Ambucias, thanks for the reply. The 'expense' of replacing the Cmos battery lies in getting to it. For Acer laptops, the whole machine has to be stripped down to the mother board. I watched a video off the internet by an expert who took an hour to do it.
But if you think it's my HD that's causing the problem, then I'll replace it. But, won't I lose all my OS and Windows programmes? I have saved my User folders, should I also save my Windows and OS progs?
