3. While still pressing those keys, press and hold down the Power button on the computer for 2-3 seconds.
4. Release all the keys.
5. At the completion of a successful CMOS reset, a message showing CMOS Reset (502) will be displayed.
6. Restart the computer.
7. Press F10 to get in to bios. Check Date and time.

If you do not see that 502 message then :

  • Press the Power button one more time (if necessary) to start the computer.
  • Tap the ESC key about once a second after you see the LEDs on the keyboard flash.
  • Do steps 7-9 above
