I have a fairly new Sony Vaio laptop that had some power problems, and they put in a new motherboard yesterday. It fixed my old problems, but now the clock is acting weird. The BIOS clock gets reset whenever I restart the computer, and the Windows time is slow: For example, it lost 40 minutes after being left on for 3 hours. Sometimes the Windows date changes to strange values, like making the year 2017.
From searching around, it looks like there is something wrong with the CMOS battery. Most places I read talked about it being too old and failing, but mine should be brand-new. So what I want to know is:
Is it possible there was something that needed to be done to enable the battery when the motherboard was being installed? Like a tab needs to be pulled or a jumper needs to be changed somewhere? Is it something I could conceivably fix myself?
Is it dangerous to run the computer with the system time unstable? I'm worried about programs getting confused thinking it's 2017 and wanted to delete files more than 5 years old, or something like that.
