Hi, and welcome to FixYa
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 issue can be caused by any of the below possibilities.
1. New hardware has been recently installed.
2. Error or confliction with settings in CMOS.
3. CMOS battery is bad or failing.
Solution:
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.

Error or confliction with settings in CMOS
If no new hardware has been added to the computer or the new hardware has been removed and you continue to receive the error, it is likely that there is an error or confliction with the CMOS. Press the key requested to enter setup and verify that all settings are correct. If everything appears to be correct try resetting the CMOS values to the defaults and/or Reset Configuration Data. Additional information about how to do this can be found on document CH000976.
If all settings appear to be correct, save changes and exit CMOS setup. If the error continues to appear, enter setup again and restore all CMOS values to default.
· See our CMOS page for additional help and information with the CMOS.
· Additional information about getting into the CMOS / BIOS setup can be found on document CH000192.
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, it is also possible that the CMOS battery may be bad or failing. Generally; when this occurs, the computer is not holding the time or date correctly. If this is occurring it is recommended that the CMOS battery be replaced.

I think that possibly the keyboard isn't completely plugged in. Several things to try.

1] re-seat the keboard
2] swap keyboards with a 'known' good one [swa[ back is ok as well]

These 2actions should narrow done the issue, I have gotten replacement keyboards at re-sale for $3.00

Try resetting the bios. There should be a hole on the underside of the laptop with letters reading "RESET" in white text.

Stick a toothpick in there and hold it for a few seconds and then try booting up again
