When I boot my laptop I have a Black Screen Password to be entered?

BIOS password
Microsoft Windows XP
I have a IBM, Thinkpad T-22 with Windows XP. When I boot the computer a black screen comes up and asked for a password. I have taken that hard drive out and put it into another computer and the samething happens. Correct me if I am wrong but, I believe that the hard drive has a Bios lock out on it. Can any body help with this matter?

Thanks. We'll let you know when a new response is added.

You will need to pull the cmos battery. and then press and hold the power button with all batterys and power removed. That should clear the CMOS and the passwords. The battery is generally accessable in two locations. I usually find it under the keyboard or via the memory cover on the back.

Once you have cleared the CMOS put the battery back.

It will redetect the HDD and ram. You may have to press F1 to continue.

That should do it.

If you have problems I have had to pull the CMOS battery press and hold Power for 30 sec and then leave it overnight. Apply power and let it boot. It just makes sure it is cleared.

NOTE: There were a few models that wrote the password to a non-clearable space. If that is the case there should be a jumper marked PW or CLEAR PW on the system board.

Second Note: If you used Bit Defender on the HDD then you may be out of luck and need to know the password to enter your HDD as Bit defender encripts the data on the drive.

    If these devices are YOURS or you have LEGALLY OBTAINED them, then the advice provided by AndOrTech is correct and should work in removing the (system) password that has been set (startup) within the bios.

    However, if you have purchased the devices (and they may be stolen, previous company, etc) then they may have additional software "hard-wired" into the bios/security chip which means that you will be required to remove the bios chip/security chip and replace with a new one.

    I advise this purely on the grounds that the devices have been legally obtained but were locked prior to purchase.

    Perhaps you have one of the Chinese models that spies on you?
