When my battery in my 1st PC was very low or even exhausted the computer date was completely back years of course.
I found that I got the messages saying that web certificates were invalid and couldn't proceed.
So by updating the time all was well, no certificates problem. I did this for a couple of years. This was with XP.
Later having a new PC I stored that old one away and took out that battery in case of leakage. Now I am trying to get Linux on that old one (now Win 7) without the battery.
The certificate warning comes up even when I have updated the time - why?
Also I cannot boot from a CD/DVD. (It auto reverts to HDD boot up). Also trying to make an ISO file in the DVD Rom drive I get the Message that, The DVD drive is not compatible with the media' (or words to that effect).
Is all this due to having no battery in the CMOS? Any advice please.
