I'm using an old (2005) desktop as a spare. The CMOS battery has been mostly dead for years. It'll only hold settings for a week or so if I unplug the PC, but has always booted up fine - I just need to hit F1 & reset the date/time and if I'm using it a lot i just leave it plugged in anyway.
Yesterday it booted fine but there was a continuous beeping from the mother board - 1 beep per second. This does not seem to be a standard beep code for a Pheonix/Award 6.0 PG bios, but others report it as well. The RAM is fine & after leaving the PC plugged in overnight there is no beeping today...
If the CMOS battery is the issue I'd just remove the mother board speaker, but it looks like it's mounted directly to the board (I guess i could crush it )
Anyone heard of a dead CMOS battery triggering a "beep" error & if so, why would it start now... it's been dead for years
