CMOS reset 502

[REO51ST]

RDR.

This would be coming from Germany but some of the best programed chips are from there.

They have also helped with master passwords.

Hi,

I understand the  CMOS reset 502

Let's try some steps to help you.

✔️ HP Recommended Solution: HP PCs - 500, 501, or 502 error displays on a blue screen 

✔️ Reset the CMOS

In some cases, the automatic BIOS recovery fails because the Complementary Metal Oxide Semiconductor (CMOS) data is corrupted. The CMOS stores BIOS settings. Use this procedure to reset the CMOS and recover the BIOS.

Turn off the computer.

Press and hold the Windows + V keys, and then simultaneously press and hold the power button. After 2 to 3 seconds, continue to press and hold the Windows + V keys, but release the power button.

When the CMOS Reset screen displays or you hear beeping sounds, release the Windows + V keys.

At the completion of a successful CMOS Reset, a message similar to the following one is displayed.

Press enter to restart the computer.

If this does not recover your computer, see Recover the BIOS.

⛔ If the issue persists, I'm afraid this is a hardware issue. Please reach out to the HP Technical Support team in your region regarding the service/replacement options.
