CMOS Error leads to no audio input

HP Recommended
HP Laptop ca1-xxx
Microsoft Windows 10 (64-bit)

So I thought it'd be a great idea to run my laptop without the battery, since it acts mainly just as a desktop and never really leaves where it's at. Took out the battery, fairly certain I didn't damage internal components, and booted it up. I was met with the whole CMOS invalid 502 screen, but I didn't really pay attention to it and continued. Just because I'd never seen it before, I turned it back off and put the battery back in. Computer booted relatively normally, if not slightly slower than usual. However, I noticed that now I get absolutely no audio input through my jack? Output works just fine, but no input from my mic. The jack is one of the 2 in 1s, and it was working just fine before, on the same headset. I've tried multiple headsets, no input from them either. My built in mic works as well. I've checked all of my settings to make sure that I have the right input and output devices, but to no avail. It now says that there is some digital jack that my input is connecting to....? idk what to do anymore
