System running win7 losing time on my Acer 8930G laptop
I was hoping that someone may be able to provide some advice re a small problem I have. Since my laptop died and I've rebuilt it. The time is not correct on it. When I power on the laptop the time is wrong and I then reset it to the correct time. If I leave it on for a few hours it seems to lose time if this makes sense. I believe the CMOS battery controls the time when the laptop is switched off and this could be the problem, but I thought that once the system was fired up the time was controlled by the operating system. Is this correct?
Also if it's the CMOS battery that needs replacing is there anyway of knowing this is the issue before dismantling. Problem is that the location of this battery requires full dismantling and reassembly. Typical manufactures they put the CMOS battery in the most inaccessible place on my laptop.
Would anything other than the CMOS battery be responsible for this isue, could it be a virus or anything along these lines..
Any advice appreciated...
