New laptop store the password without requiring a continous power so removing the battery should not help in this case. Ask to your manufacturer for your password.

In some cases for example, like Dell laptops, the password will be given by customer support.

Hi. Can someone help me with the BIOS password on my dell latitude e5500? Service tag is: 7KBVQ4J


Hi Mar Mar,
As far as I know once the you forgot your BIOS password no more options to get it anymore. You may also wanted to talk to Dell Tech Support 1-877-542-3355 in order for them to check if they can still do something about it. Worse scenario would be replacing your MOBO.

I have lost the bios password... any body help me to recover without opening case


This is a tricky one because the BIOS password is made to be the hardest password on a computer to break. Some manufacturers allow you to enter BIOS without the BIOS password but most do not. Here are some troubleshooting methods starting with the easiest and moving on to the hardest.

To enter BIOS hit the F2 key repeatedly as the computer boots up. You should enter BIOS after the first loading screen. If this does not send you into BIOS, try the ESC, DEL, and F1 keys. Once in BIOS find where you can set the password and reset it or enter a blank password as your new password.

If you can't access BIOS or are prompted for a password once you enter BIOS, try the following methods to flush the BIOS password cache:
1. Contact your manufacturer's support and ask if they have a backdoor BIOS password that they will allow you to use. This works to allow you to enter that password instead of your own and easily fixes the whole problem, but not all companies will tell you their password. You can also do a google search for your manufacturer's backdoor BIOS password since many of them have been discovered.
2. Send your laptop to your manufacturer to have them reset the password manually, although this takes an undisclosed amount of time and they will often make you pay a fee if you are not under warranty.
3. If you don't want to pay your manufacturer, open your laptop and locate the motherboard. On the motherboard there is a CMOS battery, if you don't know where this is use your PC manual. Remove the CMOS battery for an hour and then place it back on the motherboard. This should reset the password. After this turn on your computer and enter BIOS. This will reset all your BIOS settings so it may take a few minutes to open. After it is open, just exit BIOS and everything should be working properly. Just be very careful when opening the laptop and handling the CMOS battery because you can severely damage your laptop if you don't handle it properly.

Thanks for using FixYa and good luck!

My laptop Toshiba Satellite Pro A210 is locked with password in BIOS SETUP It does not recognise the original password


Wow, as I have a Toshiba Satellite Pro. I'm sorry, but there is no easy way out of this if you have enabled a bios lock. It is looking for a password that "someone" set up. I say that because there is no bios password when you setup the machine. Also, the bios password is completely different from the user or system password. (Although you could make them the same.)

Please find the person you got the computer from; type in the correct password; and be aware that it is case sensitive. Make sure the caps key is not accidentally down.

Recap:
- there is no original bios password; you would have needed to set it, and remember it. There is no recovery (that I'm aware of) to a mis-placed bios password.

Hmm...you might try opening up your laptop (or have someone do it for you if you don't feel comfortable doing this) and taking out the CMOS battery for a couple of minutes. This should reset the BIOS password.

BIOS Password


Enter the bios

You should see something that says Administrator Password, hdd password, etc.

Not all bios menus are the same so you gotta poke around a bit.

Let me know if you need any more help or if something is unclear.

Best of luck!

NEED TO BREAK THE BIOS PASSWORD ON MY SON'S DELL INSPIRON 8500


Usually there is a jumper to clear the cmos which will reset the bios password should be near the battery.
There is 3 prongs the jumper is on 2 you need to move it to cover the one that the jumper is not on.
Either that if there is only the jumper just remove it and then reseat it.

Bios password


when I was doing some research on my mysterious BIOS password problem with my Toshiba.

Long story short, Toshiba is aware of the problem and has released version 2.20 of the BIOS software which states that they have "Added a workaround for a BIOS password anomaly."

I know this is not the forum to discuss this stuff but felt compelled after the many hours of frustration, diconnects and name-rank-and-serial-number talk with Toshiba Support and Toshiba Customer Service.

Bottom line is that depending on who you talk to a Toshiba or Toshiba Customer Service, they may or may not cover the up to $200 charge for removing a BIOS password..."Toshiba does not warranty software issues". If you have this problem just be persistant until you get ahold of someone who is aware that the problem is real and who will listen. And not that morron who told me "that there is no way a BIOS password can be set without someone setting it"...idiot. They will send an "exception code" to your service provider to do the work under warranty...I mean how can they not if they're aware the problem exist and post a fix on their own website.

I just got my lab top back from my Service Provider for the second time for this problem so I don't have many hours running it to see if it happens again...I've got my fingers crossed. The first time was in July '06 and the updated software didn't come out until Sept'06. So although Toshiba gave me an exception to remove the BIOS password, the software was still corrupt and it happened again in Nov '06.
