Hi:

Restart the PC and enter this unlock passcode...

Please try this Password :

Steps to be followed:

1. Use the unlock code posted above to enter the BIOS

2. Disable all passwords that are enabled

3. If asked for current password - type the unlock code

4. For new password, just press ENTER key

5. Repeat the same for verify password column.

6. Then leave the BIOS by saving & exit option to save the changes.

That worked, and I checked the bios settings and both passwords were clear. I'm not sure how that password got set, but thanks for the help and speedy reply.

You're very welcome.

Sometimes that kind of thing happens.

If a BIOS password hadn't been set and that code appears, in the rare occasion it does happen, it is usually because a hardware component failed, such as the hard drive.

Must have been a glitch in your case.

If that ever happens to you in the future, just save that code and use it again.
