HP All-in-One - 22-df0023w

[BixMan19]

Hi there. When I try to boot up my 

HP All-in-One - 22-df0023w the screen stays black but the power light flashes and the pc makes beep tones. 3 slower lower tones followed by 4 faster higher tones. This just loops back around and doesn’t boot up. I tried replacing the mobo battery just to be safe but it didn’t do anything. Can someone tell me what I’m supposed to do here please?

Welcome to the HP Forum.

The 3:4 error indicates a component power problem.

You would have to run the PC in a minimum config using only components required to get a good POST.

1. External power brick

2. One stick of RAM

3. CPU having onboard graphics

4. MB

Then swap in each component, one at a time, until the PC will POST if the PC will not POST using factory components in a minimum config.

There is no way, I know of, to quickly ID the bad component.
