Just buy your self a new 42'' lcd screen tv and stay off line, this is better for your health. or just follow my recommendations:

Previously, I wrote about Resetting a BIOS Password , which outlined some steps that can be used to reset the security on a PC in which the password has been set in the system BIOS. Sometimes, this is referred to as a CMOS password , which is technically more accurate because password changes do not require a BIOS flash (see Computer Hope's article What is the difference between BIOS and CMOS? ), but even techs often use BIOS and CMOS interchangeably.

This information is being made available for those unfortunate people who buy a second-hand computer, say from a pawn shop, legitimately own the computer but cannot make changes to the system.

In that article, I went into how to remove the battery and discharge the motherboard in order to remove a password. Likewise, I give hints as to how to look for jumpers to reset a password if that does not work. I then wrote:


I don't know of any current motherboard where the above would not work. However, if neither of these works, then Tweaking with Vishal lists these and other methods in How to Reset / Remove / Bypass a BIOS or CMOS Password? . Personally, I would go to the end of his article and try one of the backdoor passwords before trying to use software to crack it. Resetting the CMOS with software is always a bit of a gamble, and even a small fluctuation in power while writing out new values can scramble your BIOS.

I should have written, I don't know of any current desktop motherboards where the above would not work. Laptops are a different animal, but it is valid to at least try the battery method with them. The motherboard can be difficult to get to, and it is a lot of work should there not even be a jumper to reset the password (which is very likely).

Dell Laptop don't really have an easily decipherable backdoor password, other than some older models which might have Dell (without the quotes, natch). You have to find a utility to generate the backdoor password for Latitudes.

Before going this route, I tried some of the other available password crackers, but none of them could read or wipe the CMOS settings. It takes a Dell specific site. It was a pain to find, since most of the articles I found were about Windows passwords instead of CMOS passwords, and Google for whatever reason mixed them together.

Even though I couldn't find much information on it, I was working on a Dell Laptop. Turns out that the same Dell utility site that works on older Latitudes also works on it. You can find the called Dellpasswords.com

I bought the password. I was then able to go to the other computer and unlock the Admin Password.

Please note that unlock is not the same as deleting the password! You will likely have to unlock it and then remove the password. You delete the Admin Password by entering the current password and for the new password simply press the [Enter] key. Deleting the Admin Password also removes the System Password.

I had wondered before about the debug commands listed in the external link (in my original article as quoted above). Out of curiosity, I did put the system password back on and try the debug commands outlined in the linked article:

debug
o 70 2E
o 71 FF
quit

This did nothing except waste some time. The system still required a password to get into it.

In short, only the http://dell-bios-password.biosremoval.com
worked, but it worked like a champ.

Answer 3

1) Is it a BIOS password or a Windows password?

2) If it's a Windows password, do you have the Dell Restore discs? Use the Restore Disc to reload the OS.

3) If it's a BIOS password, you can use the Service Tag Number to look up the status of the Warranty. If it's still covered they will send a tech out to remove the BIOS password.

The link below is for the warranty info. Hopefully the Service Tag is still on the bottom of the laptop.

Good Luck.

Answer 4

what is the password location when you power it up or when windows askes for a password. if its a bios password just remove cover and look for the battery there should be a 3 pronged jumper there close remove jumper from pins 23- and put on 1-2 power up nothing happens on screen power off put jumper back on 2-3 power on for a windows try Administrator no password, if thats not it email me at [e-mail]

Answer 5

There is a CD that will reset the password on any windows. The cd is called password reset cd look it up on ebay. Even if you had the OS disk you still need the pass word ..

Answer 6

In the start up menu tap f12 until the menu comes up and scroll to look for password reset

Answer 7

If it is a laptop you will have a lot of work to do. If it is a desktop you could unplug the battery. (it is about the size of a quarter and it is on the motherboard) Laptops have it also but they are really hard to get to. This could get you back to square one but not guaranteed.

Answer 8

get ahold of the person who sold it to you to get rid of the password, or call dell they will have troubleshooting tips

Answer 9

if it is not running Windows XP home Edition, I a pretty sure u could hit cancel, and it would let you go into the computer.
