Hi 996C4S,

Welcome to Microsoft Windows Vista Community site. For a better understanding of the issue let me know

A) From when did you start facing this issue, were you able to work successfully before without this issue; if so have you made any hardware / software changes?

B) Have any updates been installed recently?

C) Does any error accompany the F2 message? Mention the exact error message you receive.

I would suggest you to try out these suggestions and check if they can resolve your issue.

You likely have a defective CMOS battery or have lost the necessary boot files

Solution 1: The problem usually occurs because the CMOS battery on the motherboard is dead and the BIOS can no longer remember any settings once the system is powered off. Pressing F2 likely loads the defaults and allows you to continue. Replacing the battery will resolve this.

Likely you need replace the CMOS battery. If it's dead, or nearly so, it won't hold the settings. Then when you boot up the bios detects that the settings have defaulted and asks if you want to go into CMOS / BIOS setup and correct things. Otherwise, hitting F2 continues the boot-up with the default settings. The battery should be silver colored and about the size of a nickel. (You'll need to open the case of course.)

Solution 2: If it's not the battery you may have a BIOS problem. Sometimes you can try to correct it by selecting the 'reset configuration data' in CMOS.

IMPORTANT: Modifying BIOS/complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

Solution 3: If the issue persists, I would also suggest contacting the computer / laptop manufacturer for additional support and verify if they have any updates on this issue and if they can help to fix the same.   


Let me know if that does or does not work. Good luck!

Hope this is helpful.


Thanks and Regards,

Thanks Vijay

Unfortuately the PC is a laptop and I will have to get hold of a manual before I open the case to change the battery which is only 18 months old.

I will try to look at the BIOS (very carefully!) but I am going away next week and don't want to mess up the machine while it is still working just when I need it.

I appreciate your help and I am sure that your diagnosis is right, 

I will let you know how I get on.
