Does a desktop machine have a cmos battery? If so, could you tell me how to find it? Yes, every machine has one... as mentioned above it is usually a CR2032 and is about the size of a US nickel, mounted on the main logic board in a small black housing with a spring clip. The battery holds the cmos (bios) settings, and powers the on-board clock. Sometimes if they have a low voltage (or if they become corroded) the main logic board will complain on startup (usually a couple of beeps) with some kind of message about faulty cmos settings "loading from default" (although some systems aren't that specific) and the machine will either proceed with default cmos settings or it will "hang" waiting for user response. Sometimes the machine will give no such warning and it will either not boot, or it will behave in an erratic way. If

The CR2032 is very common and can be found almost anywhere batteries are sold... they can be pricy though... $5 -- $9 depending.

When my problem raises its head, I don't even get a bios screen. I mean, there is absolutely no output to the monitor period. Could a bad CMOS battery cause that? Greg Wallace
