press F2 to continue on boot up

HP pavilion
June 9, 2008 at 07:00:13
Specs: ME, 633\64
When I boot up I get a black sceen with white fonts telling me to press F2 to continue. When I do this it goes through the rest of the booting process. This initial screen didn't use to show up. What did I do to have this happen. I don't want to go through that step to boot up. I didn't use to have to do that. How do I get ris of that initial screen. Also sometimes I have to click on restore active desktop. What caused that? Thanks

Does any error accompany the F2 message?

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 bootup 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.)

If it's not the battery you may have a bios problem--seems to happen more often with HP's. Sometimes you can correct it by selecting the 'reset configuration data' (I think that's what it says) in cmos.

Other times you can clear the cmos. There should be a 3-pin jumper on the motherboard. It would now be jumpered in the 'normal' position. To clear it you'd move the jumper to the 'clear' position, turn the PC on for a few seconds, turn it off and then return the jumper to the 'normal' position. On next boot you'd be alerted that you need to enter setup.

But it's probably the battery. If you have a DC voltmeter you can check it. A new one would be 3.0 volts. Usually a battery will hold the settings even when it gets down to as low as 1 volt but it'd be a good idea to replace it if it gets lower than 2.8 or so.

For some reason my computertime and date got altered. I set the correct time but each time I restarted my computer the time would revert back to the same incorrect time that it was before. Then I realized the date said 1990 and it was also the wrong month. I set the date properly and it booted up properly. I don't know what happened to cause the date to change. I don't think this computer even existed in 1990. I think its from around 2000. However it is freezing up on me yet often. One time I got the message-Explorer caused an error in DIBENG.DLL and I think I was on firefox. I wasn't even using Explorer unless because of the date problem my computer wasn't using firefox when I clicked on the URL in my outlook express to reach this answer to my question. Thats when I got the error message but this time I got through. Thanks. If you have any comments let my know. If I have more problems I'll let you know or maybe its a different problem and then I'll post a new post.

The battery holds the time and date. With a dead battery the date defaults to whatever the start date is in the bios. Time defaults to midnight. So I think you can be pretty sure your battery is dead.

That shouldn't have caused the other problems unless you were running software that was date-sensitive and the uncorrected date caused an error.

Change the battery and we'll go from there.

>>>Then I realized the date said 1990 and it was also the wrong month<<<

Listen to DAVE. Your BIOS controls the current date/time, and when the battery dies (or is near death) the classic symptom is to reset the date/time to the earliest date the BIOS supports (no matter when the PC was manufactured). Other symptoms include losing or gaining time as well.

So far its been holding the correct time so Im' hoping it got corrected. If the battery is weak would that contribute to the computer freezing (mouse won't move and ctrl\alt\delete won't work). I have to turn of the computer then turn it back on and wait for the scan disc thing. When I have to do this , often if not always I have to click to restore active desktop then Im' back to normal. What is BIOS and how do I access it?

Cmos, bios setup and just 'setup' usually all mean the same thing in this context. When you first turn on the computer it'll either show the diagnostic screen where it counts through the memory and detects the drives or it'll show the HP logo. In either case, while it's doing that you hit a particular key, usually F1, F2 or DEL. I think it'll be be F1 for your HP but they'll probably be a message on the screen, something like 'Hit F1 to enter setup'. (In your case it's not going to be F2 since that continues the boot process.)

But it's unlikely there's anything there that is causing your problems. It sounds like a software problem.

The battery is only there to hold the settings while the computer is off. While it's on the settings are maintained by the power supply. And sometimes it can take up to an hour to deplete the capacitors that are holding the charge to the cmos. So when the computer is on or if it's off for only short periods of time you may not notice the typical signs of a weak battery.

"Explorer caused an error in DIBENG.DLL and I think I was on firefox."

Go into "My computer" then hit Ctrl+E and then put DIBENG.DLL into the search box.

Then right click the file(s) that are found and then check "read only" and hit okay.

Now that problem should be fixed [often there is more than one file that will do that so you have to do this for a few files]
