Solved: HP 22-B000NV PC AIO - HP Support Community

fritz57 · ‎08-19-2022

Hi. I have a problem with a PC HP 22-b000nv All-in-One, when turned on it emits 3 long beeps and 4 short beeps, this can last from two to three minutes then windows starts normally and no longer gives any problem. I downloaded the program for the diagnosis but it does not reveal any problems in the ram in the processor and in the hard disk, I also changed the ram but nothing remains the problem. Some idea? Thank you

Good morning. Thanks for the reply, I tried another power supply but the problem persists, ram changed, bios updated, disk changed, can't change CPU because it is soldered on the socket.

sorry, like i said, you should go see a professional
It could be the motherboard that is damaged, but it could be anything.
maybe a specialist can do other tests!

hi

The red light blinks three times, and then four, short white light blinks (3 long red, 4 short white)

This condition indicates a potential power system failure.

Reduce to minimum configuration (CPU, System board, PSU, 1 DIMM of memory), and then isolate the failed component.
Reduce further if issue persists.
Test your system with a known good PSU.
Contact HP Customer Support for further assistance to replace the component, system board, processor (CPU), or PSU if the issue persists.

quite fragile all-in-one computer, I advise you to consult a specialist

Buongiorno. Grazie per la risposta, ho provato un altro alimentatore ma il problema persiste, ram modificata, bios aggiornato, disco cambiato, non riesco a cambiare CPU perché è saldata sul socket.
