Hp ProDesk 600 G4 Mini Bios Problem.

Pc was getting powered on giving 3 long & 2 short beeps without ram. I tried to repair its main bios (25Q256) but something went wrong and it damaged 16Mb (25Q128) bios too. Now even with original bios, Pc gives 6 long & 3 short beeps and doesn't power on. Please help to fix these bios or if someone has working bios (16Mb & 32Mb), kindly share. Thanks.

Hoaca388, with your bios, pc is back to life but still in the previous state, i.e., 3 long & 2 short beeps but no display with ram. I have checked The processor/ ram & both are ok.

Open Q22_022300.bin with a hex editor,delete 0 - 21F (length 220) ,next select block 0 - FFFFFF (length 1000000) ,copy and paste into a new file and save.

Hi, I have an HP 600 G4 minitower computer. The BIOS was probably updated when the processor was replaced. The power went out and now the computer won't start.
Is it possible to rebuild? On another BIOS I get a 6 red 3 white or other signal

Thank you for your help. The BIOS did not help in repairing the computer. However, there must still be something damaged in the computer. Only the green LED is lit.

Please share a working bios dump for HP prodesk 600 g4 DM board F81 DA0F81MB6A0 REV A . There is no image and the usb is not active, it turns off after a minute, it does not show errors only when I remove the memory. The original firmware has damaged both images of the flash chips.

But according to the number on the case, I find that this is the Elitedesk 800 g4 dm and this number is written in the firmware, although the F81 board is exactly the same as in the Prodesk 600 g4 dm, I am confused.The computer was given away and said it would not turn on . I cleaned the firmware ME region, now it turns on itself and restarts every 30 seconds the image is not output , the USB keyboard is not active the backlight lights up for a short time .
