Prompt to press F1/F2 each time computer boots
New hardware was recently installed
If new hardware was recently installed in your computer, you may receive the prompt "Press F1 or F2 to enter setup". If you receive this message, the BIOS needs you to verify the configuration of your new hardware. Enter the CMOS setup, verify or change your hardware settings, save your configuration, and exit. If you continue to receive errors, continue to the next step.
Error or confliction with settings in CMOS
If no new hardware was added or you continue to get this prompt, verify no error or conflictions exist in CMOS. Press the indicated key to enter setup and verify that all settings are correct.
If your time and date are not set correctly, your CMOS battery is more than likely bad. Try setting the correct time and date, save the settings and then reboot. If after turning off the computer the time and date get reset again, replace the CMOS battery.
If the time and date are correct and everything else appears to be correct, try resetting the CMOS values to their default settings.
CMOS battery is bad or failing
If you continue to receive the prompt to enter setup each time the computer boots up and you have attempted to follow the above suggestions, your CMOS battery is bad. We recommend that you replace the CMOS battery.
