Why does the BIOS setting reappear with old values even after changing in BIOS Setup?

Applicable Products and Categories of This Article

Changes made to the BIOS settings were not reflected after restarting the computer.

The occurance of this symptom could be due several reasons:

- Forgto to save the changes made to the BIOS settings
- Selected the Exit without saving option instead of the Save and exit option in the setup program.
Note: These 2 options are usually located right next to each other on the BIOS Setup menu.

If the changes cannot be saved, there may be a problem with the CMOS battery. Please bring the VAIO notebook to the local service center for inspection.
