From past many days My laptop watch starts showing wrong time when ever i keep it in hibernate mode thus want to know why is it happening so ?
Is it my CMOS battery on Sony Vaio CR-363 series is dying and sign of replacing it or there is a way to remove this problem without opening my Laptop because i wonder if i open my laptop will it still remain in working conditions later .
My laptop is 7 year old at present so it normal after 7 year to show such signs of problems.
Guidance to it will be appreciated . Thanks in Advance .
Yes, wrong time and date is usually a sign that the the CMOS battery needs replacing, especially if laptop is seven years old that would be quite normal. Needless to say you can't replace the battery without opening the laptop case.
if you don't feel comfortable doing the job yourself, take it to a computer repair shop and ask them to do it for you.
