recently my laptop ran out of charge, and when i turned it on it beeped a few times and asked to set date in bios. but when my android phone has powered off suddenly, it successfully booted but with a nonsense date many years ago. why does a PC-laptop require setting date before booting the full OS?
TPM chip relies on it for security. If you’re not using that it would work but you’d still have network issues.
Are you sure there was no way to just skip that dialogue? It makes sense that it would ask about it, in case the device is supposed to run offline while still having a correct date/time set. It usually allows you to just hit Esc or some F key to continue booting tho. Might just be an odd BIOS.
The BIOS on that is clearly a bit odd, I haven’t seen that as a requirement before. That said, the BIOS battery is probably dead. Replace that and it should fix the issue.
I am fairly certain that I have had a PC before that had exactly the issue that the CMOS battery ran out. It was able to boot just fine, I just couldn’t get it to connect to the internet properly. Took me ages to figure out that the date and time in the OS were completely wrong, because I never really use my computer as a clock anyways.
