Can the CMOS battery stop the computer from turning on?

Although, usually you'll simply see information asking you to go to the BIOS and reset information that has been lost because the battery is dead.

But, I've seen completely dead or missing CMOS batteries prevent any kind of boot up what-so-ever.

If you need more information than that, you'll need to provide details of the system as well as what the current problem is.

Cause all sorts of problems with the system booting. They start off wanting the Date & Time to be reentered and then will fall over at different points along the POST process.

Generally when the battery is on it's way out you'll get different error messages but the Date & Time will always be incorrect causing the system to not proceed past the initial look at the files on the HDD. Because they appear to be written after the Date that the BIOS is showing the system hangs and can not proceed.

I just replace the BIOS Batteries in Desktops as they are cheap easily removed and replaced and you just need a CD2032 Type Battery. You should be able to get one of these for under $5.00 at any shop that has a range of Batteries available.
