Question Optiplex 745 Beep Codes

I have a video of the beep code for greater clarity on the issue. Any help greatly appreciated.

Thanks for the pdf, but can you tell me what these beeps mean? I can't even fully discern where the patterns are. I need help desperately!

Check you motherboard battery. Had a 745 same as you and if not plugged in wall for a long time it would do all kinds of beeping on re hookup.

Okay, I will do. Did you just replace it, or take it out and put it back in? Mine has indeed been unplugged for some time now.

Most of the time just pull and replace same battery. But check it while you have it out 3 volts is a good battery 2.8 is not.
