HP 20-c020 error code

[NotABigGamer]

I got a hp 20-c020 all in one from a friend to keep. However when I turn it on before it boots it lets out a ear piercingly loud error code. It goes 3 long lower pitched beeps then 4 shorter higher pitched ones. It repeats 5 times then turns on like normal. I have taken it apart and unplugged the speakers. I have tried with and without anything plugged into it. I have replaced the cmos battery and that didn't work either. The only think that I can think of is that I am not using an oem power cable. Would that effect anything? Is it something else? I can't find anything from HP about this computer.

Thanks!

That's a CMOS checksum error. 

1st step, try and clear the cmos one good time.

 

1 short beep
Legacy floppy drive or CD/DVD drive not detected
2 short beeps Floppy diskette or compact disc not detected
3 short beeps
Unble to start flashing (such as when missing a utility or BIOS image)
4 short beeps Flashing failed (checksum error, corrupted image, etc.) 
5 short beeps BIOS recovery successful

To clear the cmos all I have to do is take the cmos battery out for a while right?

 

I tried that and replaced the battery and still the same error.

Must remove the power or switch off the psu.

Ok I think I did it right then.  It wasn't plugged in when I took out the battery.

The only other 2 options is 

 

A. Flash the bios and hope it recovers.

B. Replace the bios chip. (Bios Depot on E-bay)

I flashed the bios to the latest version and still the same error code. 

 

I don't think I have the skill or resources to replace the bios chip if that's the issue.

 

Could it be possibly anything else?

 

It sucks that hp added this annoying feature. I would still be usable if the light only flashed instead of it playing the error code extremely loud.

 

Thank you for your help and time!

There's really no other way that I know of unless it's some weird issue with something that's plugged into the board or possible memory errors, but typically it's a corrupt bios or bios setting that causes it.

 

You could simply disconnect the speaker so you don't have to hear the beeps, and just wait for the PC to post after the 5 cycles of errors.

I already have the speakers unplugged. The only issue I have with it is that it adds quite a bit of time to start up. It wouldn't be a big deal to me but it might be to the person who I am giving it to.

Oh I see. There's not a whole lot you can do at this point. I'd call the board shot and perhaps an alternative for your friend honestly.

I got it for free so it's not a big loss. 

 

It works perfectly fine otherwise. I wonder if there is a way to disable the error code somehow. 

 

Thanks again for your help!

Nope, the bios is borked. It happens. I've had a few boards similar. Would work fine after a cmos checksum error. But the aftermarket boards usually post after a soft reset. Some occasions, won't save bios settings with the checksum error also. Just depends on how they fail.
