The official method is to contact Dell Technical Support. Dell Technical Support will request the Service Tag and Express Service Code from the bottom of the Latitude. If the current user is not the original Latitude owner, Dell will transfer the used Latitude's registration from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.

  • For most Dell Dimension desktops, the steps to reset a BIOS password and clear all CMOS settings are:
    • Locate the 3-pin CMOS password reset jumper on the system board.
    • Remove the jumper plug from pins 1 and 2.
    • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
    • Replace the jumper plug on pins 1 and 2.

The another method is: by Using the Motherboard Jumper: In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off, and remove the battery and power cord
( if it is a laptop ) before you continue.

Here is a picture how it looks like:

The default setting is:pin 1 to 2, to clear cmos: 2 to 3.

Best of luck :-)

I forgot BIOS password for SONY PCG-GRX520


The best way for the Sony is to remove the cmos battery for at least 30 minutes. Remove the main laptop battery and leave it out. Make sure the power adapter is not attached. The cmos battery can be reached after removing the keyboard and is attached to the motherboard vis a small cable. If you have a "jumper" that come equipped on hard drives to jump the pins on the back, you can "short" the pin connections on the cmos battery socket, power the laptop up using the ac adapter and letting the computer go through the bootup process. When this happens power the laptop back down, take the jumper off and replace the cmos battery. Power back on with just the ac adapter and boot the computer. If the laptop still askes for a bios password just hit enter and it should allow you to log in. Once in go into the bios and reset the date and time. Once that is done power down and replace the main battery. Reboot the laptop and let Windows load.

Don't reset password BIOS HP DC7100


If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard.

Open the CPU casing locate the CMOS battery in motherboard and remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper.

This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.

If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it. Good luck!

Dell D505 BIOS Reset


Generally, all you need to do is get on to Dell Support and get in a chat with one of their people and tell them that you are locked out by a BIOS password, and needed to get around it. After they verify that you are the owner of the laptop, they should give you a password that gets you through it.
