missing something really simple?
"F2 to enter setup" probably means to enter your BIOS configuration
screens after the POC (power-on check) has completed. So do you end up
in the BIOS screens? Hard to know since you never identified WHICH
laptop you have. Someone with the same brand and model could tell you
what F2 does on startup. That is not a trigger key for Windows to alter
its startup (i.e., by showing an OS boot menu) unless the OEM modified
Windows.
How long does the laptop sit unpowered before you boot it when the
problem reoccurs? If it is okay for a week then maybe it is because you
didn't let it sit as long unused before using it the next time. In that
case, maybe you need to replace the battery. You never mentioned if the
laptop was on battery or AC power.
The BIOS issuing the message that you need to enter it often means the
CRC for the CMOS table is invalid (i.e., the BIOS copy of settings in
the CMOS table is corrupted). You have to go into the BIOS and save its
settings to force a rewrite of the *copy* of the settings saved in the
CMOS. If this is what is happening and it happens more than once then
maybe you need to replace the CMOS battery.
