    It is an Acer laptop and if I could find the battery or jumper I would know what to do. It can only be dismantled so far: I removed keyboard, all screws and it only open about an inch.

Unplug the computer, remove the computer cover(usually 2-4 philips head screws),remove the small round battery (cmos) from the main board for about 2 minutes, replace it, install cover, power cord, REBOOT.
this will clear the password and reset the bios to defaults.

How to Bypass BIOS Passwords


BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets their password, or changes the password to intentionally lock out the corporate IT department. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in the warranty. Never fear, all is not lost. There are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS v Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include:
Using a manufacturers backdoor password to access the BIOS
Use password cracking software
Reset the CMOS using the jumpers or solder beads.
Removing the CMOS battery for at least 10 minutes
Overloading the keyboard buffer
Using a professional service
Please remember that most BIOS passwords do not protect the hard drive, so if you need to recover the data, simply remove the hard drive and install it in an identical system, or configure it as a slave drive in an existing system. The exception to this are laptops, especially IBM Thinkpads, which silently lock the hard drive if the supervisor password is enabled. If the supervisor password is reset without resetting the and hard drive as well, you will be unable to access the data on the drive.
----------------------------------------------------------------------------------------------------------- Backdoor passwords
Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.
WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords

Remove hdd password


You can change it but not 'remove' it. Simplest is to use '00000' as the default password.
Instructions
1 Shut down your computer.
2 Press the power button on your computer. While it is booting, press F2 repeatedly (do not just hold it down) until you arrive at a system screen showing a series of
options. This screen is called the BIOS Setup.

3 Use the down arrow key on your keyboard to scroll down to "Security" in the left-hand column.
4 Arrow right to display a sub-menu under Security in the left-hand column.
5 Arrow down to "Internal HD PW" in the left-hand column. (That stands for Internal Hard Drive Password.)
6 Delete the old password (if any) and, in the same box, enter a new password of at least four characters in length in the main screen at right.
7 Write the password down and keep it in a safe place.
8 Hit Enter.
9 Hit the Escape button on your keyboard to exit the Internal HD PW menu, then hit Escape again to proceed to the Exit screen of the BIOS Setup.
10 Arrow right to save the changes you made to the password, then hit Enter on your keyboard to exit the BIOS Setup.
11 Restart your computer and use the password you created in the BIOS Setup to gain access to your hard drive.

if this fails to remove your password


The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.


click start control panel Open User Accounts in Control Panel. On the Users tab, click the name of the user whose password you want to change, and then click Reset Password. In New password and Confirm new password, type the new password, and then click OK. Notes You can change passwords only for local computer accounts, such as guest, administrator, or accounts you create for your computer. You cannot change your network logon password in User Accounts. To change your own password, press CTRL ALT DELETE and then click Change Password

as well as the password and you'll need to re-enter all settings.

Under the keyboard or bottom of laptop - If you are working on a laptop computerthe location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

If it fails, then try to remove the battery for at least one hour.

How do I get my Vostro to boot from disk instead of HD It has been password protected and I do not have the password.


Turn on your compter and repeatedly press F2 (or F12) to enter the BIOS set-up. When you get to the BIOS, change the order of the start-up to read from your disk first.

Good luck!

Dell dimension 3000 + maxtor hard drive. comp wont start


Try the following to see if it's helpful:

1) Turn the computer on

2) Press F2 to enter the BIOS ( a grey screen should come up)

3) Turn on caps lock,scroll lock and num lock on your keybord

4) Press Alt +E then Alt +F then Alt +B


If that doesn't work you can pull the CMOS battery to clear the BIOS. It is on the board and resembles a watch battery. You have to pull it for no less than 15 minutes to clear the BIOS.
