Need to reset power-on password on IBM ThinkPad 600

I have an IBM ThinkPad 600. I borrowed it to a friend of mine and he managed to turn on the boot password. Neither him not me know what the password is. I need to know how to physically clear the contents of the CMOS.

Thanks

This is fairly easy and involves invoking a short circuit behind the DIMM slot cover.

I recommend that you consult the hardware maintenanace manual. It's available online and explains better than I could here since the manual includes diagrams to show all the bits it talks about.

To get the manual, do the following....

  Go to www.pc.ibm.com/support?page=IBM+ThinkPad

  Under 'Select Family', click on ThinkPad 600

  Select 'Online Publications'

  Select 'Hardware Maintenance Manuals'

  Click on 'TP 600 Hardware Maintenance Manual (September 1998)'

  Download or open the file called '600hmm.pdf' (>800KB). This
  file is in Adobe Acrobat format. (If you need this, it's free
  from www.adobe.com.)

  Follow the instructions on page 13 'How To Remove Power-On
  Passwords' and refer to the diagrams in the 'Locations'
  section in the manual as prompted.

I hope this helps.

Best regards,

As I recall, the thinkpads can can be reset with a gizmo that plugs into the parallel port. Call a local IBM cert to have it done.
And be careful who you let play with your toys.
