For your problem the computer may display a prompt to press F1/F2 or any other key to enter setup each time the computer boots as a reminder on how to enter CMOS. However, if the computer asks to press F1/F2 (or another key) to enter setup and does not continue, this may be caused by any of the below reasons.
New hardware has been recently installed
If new hardware has been recently installed into the computer, it is likely that you are receiving the prompt "Press F1 or F2 to enter setup" because CMOS needs to verify that the new detected hardware is properly being setup in CMOS. Enter CMOS setup and save the settings and exit. If you continue to get errors continue to the next step.
Error or confliction with settings in CMOS
If no new hardware has been added or you continue to get this prompt verify no error or conflictions exist in CMOS. Press the key to enter setup and verify that all settings are correct.
If your time and date are not set correctly, your 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 battery.
If the time and date are correct and everything else appears to be correct try resetting the CMOS values to the defaults.
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 recommended that the CMOS battery be replaced.
hope this will help you.
