If you can find a way to open the laptop, removing the CMOS battery for a few mins and reinserting it will return the BIOS settings to factory defaults and thus no more password.

*Latitude L400*
You can clear
the password from this
laptop simply by removing
that CMOS Battery for 5 minutes.

Most painless way would be to obtain a bios upgrade for the make/model of the Dell system. Flash with the DOS utility. This will reset the bios to factory setting. Ask around to find some one with a Dell user account. They can access the necessary utility and bios version for you. The whole install takes about 5 minutes...

I have a Dell support account. I"ve located the file you need to flash & update the Bios.. You need the Dell File C610-A16.Exe. This is a Dos based flash utility. You copy it to a Floppy formated with a Dos system file then reboot and follow the promts.. If you can't access Dell just e-mail me and I'll forward the file.

Hi, I am helping my Brother fix his BIOS on the above computer. I installed a new hard-drive and downloaded drivers from the Dell website. However, I need to update or fix the bios. When starting up, I hit F2 to go into the BIOS and when It comes up, it hangs and the only way to get out of it is to hold the off button a few seconds and then let it reboot properly. I went to Dell Website and found the upgraded BIOS but didnt want to mess with it becasue the computer is working fine just the fact the BIOS hangs when pushing F2? Any help would be greatly apprecaited.

It is not a bios password, it is a boot password. You will have to contact the manufacturer. If there are jumpers, then you are lucky, but newer models have a security chip installed. You may need to contact the manufacturer in order to obtain the master admin password for that laptop. You could also replace the security chip, if you want to get crazy.

Have you considered contacting the seller???

This URL has the information to eleviate your worries or increase them twofold.
You need to be fairly confident working with electronics (no soldering or repairing).
I've used this method on CPiA 500Mhz no problem.

Follow the instructions to the letter and read all the information advised.
It's not complex just fiddly.
Good Luck.

...for the '***ware' infested link. Joke. Thanks, the site has some solid info. :)

You can replace the 24u05 chip, but I would suggest simply shorting the chip.
Saudering on a laptop requires alot of skill and the extreme heat can damage it very easily. I sale guides on shorting the bios chip at http://www.aleman-core.com

JP1 on the motherboard- short the jumper amnd apply power to the MB for about 3 seconds this should clear the password. If it is not designated JP1 it should be CMOS clear. More info can be found on the Dell website (Dell.com) under product support. You can look up the exact system using the service tag on the back of the machine. The tag is usually a 5 place combination of digits and letters.
Hope this helps.

you will need to take keyboard off and palm rest. You will find the cmos battery unplug for a few minutes

Have you considered shoving it out the nearest window? The crack will happen when it hits the ground at 32 ft/sec-squared.

Isn't their technical support a treat?

After my own particular nightmare with them that went on for months as a mission-critical system went into the dumper, they finally admitted, "Well, it looks like the disk controllers are failing." I knew that when the drive would scramble on a repartitioning.

Suffice to say, not a brand I have any faith in.

And Dell should be accepting the service tag number located somewhere inconveniently on the box.

Did you try the cmos battery? Can it be pulled out? Pull out the cmos battery for 30 seconds. This should work. LEt me know if it doesnt

Removing the Reserve Battery
NOTICE: The reserve battery provides power to the computer's RTC and NVRAM when the computer is turned off. Removing the battery causes the computer to lose the date and time information as well as all user-specified parameters in the BIOS. If possible, make a copy of this information before you remove the reserve battery.
NOTICE: Disconnect the computer and any attached devices from electrical outlets, and remove any installed batteries.
NOTICE: To avoid ESD, ground yourself by using a wrist grounding strap or by touching an unpainted metal surface on the computer.
NOTICE: Read "Preparing to Work Inside the Computer" before performing the following procedure.

1. Remove the hard drive.

2. Remove the keyboard.

3. Disconnect the reserve battery cable from the system board connector.

4. Pry the reserve battery free from the system board. The reserve battery is attached to the system board with a piece of adhesive tape.

5. Remove any remnants of the adhesive tape from the system board.

Replacing the Reserve Battery

1. Connect the reserve battery cable to the system board connector.

2. Position the reserve battery above the speaker connector on the system board.

3. Update the BIOS using a flash BIOS update program floppy disk or CD. For instructions on how to flash the BIOS, see "Flashing the BIOS."

See, that is the problem with the mail today. It just takes FOREVER for a package to get delivered.

Your post for example is almost two years too last, as the original post was back in 2004.

I really hope that the user is not still waiting for your answer in order to resolve his issue. :p

Are you having trouble with a bios password or a Operating system password?

If it is a bios password you can replace the 24u05 chip or chort it to erase the password.

I sale a guide that shows you how to do it. Heres the link
http://www.aleman-core.com/hoobly.htm
The quick reference guide is for someone that knows how to take a laptop apart..etc..its 4$..
Worth it though.

A. 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 before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds
