Used lenovo t400 supervisor password reset

Bought a used thinkpad T400 from the bay.
It has the BIOS supervisor password set and the seller doesn't know it.

Trying to decide if I should send it back or keep it.
The seller never indicated the BIOS supervisor password was set.

Shipping cost is a pain, but this machine is limited with the BIOS locked!

Looks like you have to solder a few wired on the bios chip to extract the password, yech!

Not sure what to do.

  1. Forum rules do not allow answers to "Laptop BIOS Passwords Reset" questions - Please contact the seller or the manufacturer - Thanks for your understanding.
  2. Hello jsmakkar;

    Where is that rule about "Laptop BIOS Passwords Reset"?
    I've been around a while and never seen it.
  3. Hi WR2

    Thanks for poiting that out. My understanding was that questions about password resets can't be answered here. I am pretty new to Forums and maybe I might have misunderstood something. My apologies.
  4. As far as I know it's no problem to help someone do work on a laptop they own.
    Usually, we point at the sticky FAQ topic: LOCKED OUT OF YOUR LAPTOP?
    But you're not the only one to suggest there is aspecific rule or something similar.

    So I've kicked that question upstairs to see what's up.
  5. There's a big difference in helping someone crack/bypass passwords, and pointing them to the manufacturer.

    As we cannot verify the owner of the PC, we are very cautious about helping people break thru password protection. The standard answer for BIOS passwords, is probably just point them to the manufacturer.
  6. Thanks aford10 for clarifying that.

    I'm simple asking if I should keep it ir sent it back to the seller!
  8. Will I be able too upgrade the memory without knowing the bios password?
    Anybody?
  9. Yes, you can increase the RAM, without needing the BIOS password. That just involves adding RAM chips to the slots.
  10. Thanks, I may just keep it then.
    It works ok, and if I can add memory then it suits my needs.

    Moderator aford10 already clarified that above.
  12. Remove the battery and remove the backup battery (CMOS Battery).
