T23 SVP gone

After changing the back-up battery on the T23 it booted-up again but....asking for a supervisor password which I can't remember anymore. Is there hope I can still use my T23 again. Please let me know if there is a workaround.
By the way I have the 2648 model

    Thanks thespark,
    I've solved it after accidentally the battery emptied itself and automatically the T23 went to sleep when I was still guessing for a supervisor password. After plugging in the power again to reboot using F12 to start-up from CD (Linux) to avoid the password => no luck again it kept on asking to change the time/date in the BIOS which I couldn't enter due to the forgotten password.
    Space (no reaction) enter => password not accepted
    enter => yes it worked!?! I was in the BIOS.
    Went to passwords section to clean/change all password => not possible however all passwords were disabled (YES!!) go to restart and no possibility to change anything as all was blocked. That should be a problem as all passwords were disabled anyway I thought. I've rebooted again as expected the question to change time/date hit enter to go into BIOS worked this time however Supervisor password was enabled again?!? and nothing could be changed to save. Rebooted F12 to alter boot still question to change time/date. I've used esc twice and it started form the selected boot options (HD) change time in the OS and rebooted. At last it started up as normal and is still working good in fact I've upgrade the memory with 512mb extra to work quite a bit faster. Next job get Linux working on a T23.

    If you don't try, you don't fix it!

    Best regards,
    M@x

Ah! Passwords.... Do you see anything about WINDOWS before it ask? Then its a windows password and you can go hunt all over filesharing land for a PE disk, preferably a Winternals PE disk.. or be nice and buy one.. On a borrowed computer of course..

Nothing about windows before it asks for a P/W? Oh goody bios password... Much more trouble.. On IBM machine really nasty... Your HD is probably locked too.. You can spend hours on google after this, but you may have a brick.. or be looking at building a custom board with instructions from this guy in Australia, hooking teeny tiny wires to a chip on your laptop baord, running a program and sending the result and $25 to him..
IBM laptops=great bloody bios password security.. Oh.. Co. up in Canada does it for $400, after proof you own the thing..

Good hunting..

I forget my lenovo 3000 y500 bios password, how do i bios open without open the cmos


Normally, you can just move a jumper or unplug the CMOS battery to clear the password. But, I found the following in the Ideapad Y500 repair manual:

"A supervisor password (SVP) protects the system information stored in the BIOS Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee."

Forgot My Pin Number. how do retrieve it .


Hola Sorry to say but if this is the right one i searched for the manual found
http://download.lenovo.com/UserFiles/UserGuide/en/User's%20guides%20and%20manuals/K1/Lenovo%20IdeaPad%20Tablet%20K1%20Hardware%20Maintenance%20Manual.pdf
IT said as following:

As many as two passwords may be needed for any Lenovo IdeaPad computer: the power-on password (POP) and the supervisor password (SVP). If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is turned on. The computer does not start until the password is entered.

Exception: If only an SVP is installed, the password prompt does not appear when the operating system is booted.

Power-on password

A power-on password (POP) protects the system from being powered on by an unauthorized person. The password must be entered before an operating system can be booted.

Supervisor password

A supervisor password (SVP) protects the system information stored in the BIOS Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup Utility and change the system configuration.

Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee.



Sorry hope this helps a little good luck

PLEASE I NEED A POWER ON PASSWORD FOR MY IBM T23


Hi there, sorry to hear you are having problems. Please follow this How to Reset an IBM ThinkPad Power On Password Using Hardware

If you cannot boot the ThinkPad, you will have to reset the IBM ThinkPad password via hardware.

If only the power-on password is set, do the following to remove the power-on password.

  1. Power off the computer
  2. Remove the DIMM cover on the bottom side of the computer.
  3. Short-circuit the two password pads or put a jumper on the contacts to short the circuit.
  4. Under the short-circuit condition, power on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The power-on password is removed.
  5. Reinstall the DIMM cover.

If both the power-on password and the supervisor password are set, do the following to remove the passwords:

  1. Power on the computer by pressing and holding F1.
  2. Enter the supervisor password. The Easy-Setup menu appears.
  3. Click on the Password icon.
  4. Click on the Power on icon.
  5. Enter the supervisor password and press the Space bar.
  6. Press Enter twice.
  7. Click on Exit; then click on Restart.

From your hardware maintenance manual:

Supervisor password: A supervisor password (SVP) protects the system information stored in the BIOS Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup Utility and change the system configuration.

Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee.

Unable to change bios settings


are you sure your are exiting the bios saving your changes?
if for some reason you are unable to save your changes it is possible that the cmos battery is going bad, replace the battery and test.

another reason why you may not be able to make any changes is because you may not be a supervisor or accessing the bios as a supervisor but as a user. you may have set a bios supervisor password. if you don't remember what that was you may have to reset the password:

to reset your password do the following:

  1. Turn off the computer.
  2. Open the computer case.
  3. Locate the blue J8C2 Flash/PWD jumper block on the motherboard.
  4. Place the jumper on pins 2 and 3 for clearing the passwords.
  5. Turn on the computer. Wait for an audible beep from the computer. A message appears stating that the NVRAM and password have been cleared.
  6. Turn off the computer.
  7. Place the jumper back on pins 1 and 2 for normal operation.
  8. Place the lid back on the case.
  9. Turn on the computer.
good luck!

How do I access BIOS if I don't know the Password?


If upon boot up and pressing DEL button asks a supervisor password, then you just need to take out the CMOS battery from your computer's mother board. Let it stay for like 3 minutes and return back the battery. This will remove the password in the bios. Good luck!

How to clear supervisor password in bios in 945 gccr


If you remember the password, simply enter into the bios/cmos setup, go to the section to change the password, and leave the new password fields blank. I haven't looked at the manual for this specific MB, but that is the standard way to clear any passwords stored in bios. Hope that helps! Let me know!
