The only real thing you can do is to remove your cmos battery for about 5 mins and reset the password. The battery is on the mother board, It looks like a watch battery.Just pop it out and wait for about five mins and you should be good to go. Make sure you unplug the computer before you do this.

Why do I keep getting a pop up asking for my password over and over again on a black screen?

If this occurs on a Window-based PC prior to seeing the Windows Start screen, it most likely means that someone has entered a System Password into the CMOS/BIOS that requires entry before the system will boot. If your CMOS/BIOS was not password-protected anyone who had access to the machine would be able to enter the CMOS and set up such a password, effectively locking you out. Of course, it they did not put a password on the CMOS itself, you may be able to enter the CMOS yourself and remove the password, as long as you do not have to know it to remove it. If you MUST know the password, you may have to do a CMOS reset to release the password. Ensure that if you do that, you know all settings in the CMOS that need to be modified from default or you may have operational issues later. If there is a CMOS password on the system as well, and you did not place it there, someone is messing with your head.

How do I run a set up program

Generally, one enters the BIOS Setup screen by pressing either F2 or Del. There is usually a message on the bottom of the first boot screen that indicates what button is correct for that model.

Looking further into the details that you have given, it seems that your CMOS battery has died, so you will need to replace that. (This is what is causing the "Time of Day Not Set" message most likely.) You can get the appropriate battery at Radio Shack (if nowhere else) for about $5 or $6.

I fired an employee, but before he left he has set up restrictions on my inspiron,how can i override password protect and special privalages obtion?

If the password is software driven, and your company purchased the software, with proof of purchase the software help should given you a contact number to their tech department.
(I had forgotten my password to my security suite, and with proof of purchased (and registration) they were able to send me a password reset option.

If the password is in your bios on your system, remove the CMOS battery and this will reset the motherboard to the default setting (without passwords)

Reset cmos password on hp 8430 notebook

My friend, you are out of luck. HP has one of the better BIOS password protection in the market, and only HP has the tools to reset it. Of course they must charge about $200, once you provide proof of ownership.

Dell2 2400 BIOS F2 reads backwords.

It sounds like you may have the IDE cables hooked up backwards on your motherboard.. The IDE cable slot on the motherboard labled IDE1 should be where your Hard drives are if you want them to read as primary. The Optical drives are usually on IDE2, designating them as secondary.
Let me know if you need more help.

Hi i'm Rain.
Ye it sounds like you BIOS is corrupted. If your unable to get to DESKTOP to save anything you may have lost it all . you could replace the harddrive and save the old one to see if you can have the data pulled from it. Reinstall Windows . Windows has the correct bios settings . This will correct your problem . If the time and date will not stay set you may need to replace your CMOS battery.
