Removing bios passwords


Disconnect power from the computer, then open the computer up and remove the BIOS battery and wait about 30 minutes for all power to drain from the computer. Replace the BIOS battery, reconnect power and turn on. The BIOS password should now be cleared.

The BIOS battery in most desktop/laptop is usually a lithium button battery, round and silver like a very small flat coin, located somewhere on the motherboard. It is fairly easy to remove in a desktop. Laptops are more difficult.

REMOVE BIOS AND POWER ON PASSWORD ON THINKPAD LAPTOPS


THINKPAD BIOS AND POWER ON PASSWORD
The BIOS password is configured from the BIOS setup and this password is stored on a 20RF08 EEPROM chip. There is no backdoor password available and IBM/Lenevo support says the motherboard needs to be replaced. Also removing the BIOS battery to discharge the BIOS and reset it to the default settings will not allow you to bypass this password.
This also applies to the Power On Password and the Hard Disk Password.

There is a way to crack the password but you need electronic skills, electronic components and several programs plus a working computer to carry out this task.
For details on how to do this, check out this WEB site.

I can't reset my bios password


BIOS password can be removed using either of these two ways:

1) Take you BIOS cell out for a while and then plug it in again and your BIOS password shall be removed.

2) You can also change your BIOS Jumper Setting. Generally the BIOS jumper resides on pin 1 and 2. You simple take it out and then plant it in on pin 2 and 3. Power on your computer and then power it off. Then change the jumper to default setting that is pin 1 & 2 and then once you shall power on your laptop the BIOS password shall be removed.


The BIOS jumper resides on the motherboard and there is a marking on it stating "BIOS" which shall help you identify the correct jumper.

How do i reset the bios password for my lenovo a310?


User passwords:
Power on
BIOS execution can be controlled by a Power On Password. This password is set in the BIOS Configuration screen, accessed by pressing the F1 key after pressing the power on switch to turn on the PC. If the person at the keyboard does not know the Power On Password, then BIOS execution halts.

Hard drive
The hard drive is controlled by the Hard Drive Password. After the Power On Password is entered, the person at the keyboard must be able to enter the Hard Drive Password, otherwise the disk drive will not spin up for use. Like the Power On Password, the Hard Drive Password is set in the BIOS configuration screen.

Administrative passwords:
Each of the two user passwords can be controlled by a Master or administrative password. If the administrative password is not set, then anyone who knows the user password can change it in the BIOS configuration screen. If the administration password is set, then it is impossible to reset the user password unless you know the administrative password. The Supervisor Password is the administrative password for the Power On Password. The Master Hard Drive Password controls the Hard Drive Password.

Password Recovery is a feature of Client Security Solution 6.0. This makes it possible for an end user to recover from the problem of "I forgot my Power On Password or Hard Drive Password."

Remove administrator Password.BIOS password


Hi

This is really, really strange but the BIOS password can be removed only by a local ASP. The technician will remove it and will update the BIOS to prevent such further, unexplained password settings.

ACER ASPIRE 4730Z. How do I clear the CMOS (password)?


Below is the steps for clearing the password. Below that is the link for the manual, the picture of the jumper tabs is on pg. 153, good luck

Steps for Clearing BIOS Password Check

If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:
• Power Off a system, and remove HDD, AC and Battery from the machine.
• Open the back cover of the machine, and find out the HW Gap on M/B as picture.
• Use an electric conductivity tool to short the two points of the HW Gap.
• Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.
• Restart system. Press F2 key to enter BIOS Setup menu.
• If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.
NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).

Power On password has been enabled on the notebook


The power on password is configured from the BIOS and removing the BIOS battery will not reset the BIOS and remove the password as it is stored on an EEPROM chip.
This password is to protect unauthorized access to data on the laptop and the hard drive. There are no backdoor passwords available.
Ask the person who set the password, then you will be able to remove it by going into the BIOS setup.

I set the power on password on my ibm 600e and now cant turn it off. How do I do that


go to www.ibm.com go to support page, download the service manual of your model first, it will show you how to reset your bios password or remove your bios passord, usually remove the bios password, it is your CMOS battery (look like a calculator battery) unplug it, and put it back on again, your bios password should disappear. make sure remove the battery first.
