How do i unlock my bios password on a blue screen i forgot it

Are you needing to bypass the Microsoft Windows password or the Acer BIOS password?

For the BIOS password, try the password three times, and a dialog box should pop up with a code. Enter the code to unlock the bios here. It may work for your model.

If you forgot both your password and security question, you can call Nintendo and they can help you unlock your DSi. The number is 1-800-255-3700. The number displayed is what the support personnel will need to help you unlock your DSi. Hope this helps!

When you boot up to the log in screen type in administrator to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up

Press and hold that key during the boot up process to enter BIOS scroll down to set user password or supervisor password you can change or remove your password from there

or

control panel user accounts

on the users tab,click the name of the computer administrator you can change the password there

hope this helps

Every laptop has a different configuration and hardware setup so knowing what your brand and model is helps. Unless your computer is part of corporate inventory there is no reason to set a bios password. Check ebay for bios password as there are store fronts that can help you unlock it for a fee. Some places require you to send the machine in as it can be complicated to reset this security feature. If you want security then buy a notebook lock and put a power on, user and screen saver password but never enable a bios password.

Here are a couple of links that may help you to reset the password.

Why not just go to safe mode with networking support then scan the drive with housecall over at http://housecall.trendmicro.com/ or one of the many other free online virus scanners.
Seems to me it would be easier than removing the drive.  ut if your dead set on removing the drive usually if you look at the machine there will be a pannel on the front about an inch wider than the drive itslf.  flip the computer over and there should be one screw in the middle of that pannel or paossibly one on each end. 

Unscrew them and the drive should slide right out. If you take them out and it still is stuck in there then pull the pannel out a bit and look inside for an extra screw, but most of the time its just the one.
When putting it back in make sure you have it back in the hard drive enclosure correctly and the addapter on if it was on it when you pulled it out, then just slide it back in and put screws in.

hope this helps.

There are several types of password lock ups.
If you forgot the password on the log on screen where it asks for the username and password, you need to do recovery on the computer with the recovery disc that comes with it.

If the lock up is upon powering on the computer where you can see a blue screen and asks for a password, it is a BIOS power on password and there is no way to bypass this. You need to send it to an authorized service provider to reset it.

If it is an HDD password upon boot up, sad to say, the HDD needs to be replaced.

Hope this helps.

If you dont know the password you have to clear the bios to unlock it. Post the motherboard model number and i'll tell you how.

try the last 4 digits of your phone number.
