Instructions
on how to actually unlock your ThinkPad (TP) are in the User's
Guides
EEPROM
Location and Type
R60
you treat as EEPROM Type 24RF08
----------R60 Password recovery procedure
----------
The following steps requires CARE read
all the information first, before you do ANYTHING, get a feel for the
overall procedure, ONLY THEN start to follow the procedure.
Locating the R60 connection points
Switch the R60 OFF.
You should have already downloaded the
hardware Maintenance Manual for your ThinkPad model, if you have not
done so use the link below to download it now,
Download
the Hardware Maintenance Manual (HMM) for your TP model
The links above are to the Lenovo site, if it
doesn't work, don't panic, it isn't broken, their site is shut down
daily for maintenance and at those times they display spurious
messages like the page you requested cannot be found, wait a good
while and try again.
Scroll down this page to see different versions of the System Board
and connection points
Once you have your HMM search the manual
for "Removing and replacing a FRU" then scroll down to System
Board, follow the instructions in the manual to remove all the other
FRUs to gain access to and remove the System Board.
You need to access the pads as
illustrated below, note the connection points are just under the front
left edge of the keyboard.
Alternate connection points on some R60
models
The IC is under black tape, in this image
the black tape has been cut away
In this case a customer soldered fine green
coloured insulated wires to SDA SCL, you can do that or use the sharp
probes, your choice.
close up image of the ATMEL 8356908 chip
SCL and SDA points are shown above.
GND is connected to either of the metal
fingers which normally clip in the RAM.
You can attach to the GND connection using an
alligator clip.
Alternate connection points on some R60
models
No shortcuts on this version, no easy
connections near the BROADCOM CHIP, the system board has to be removed
to gain access to ATMEL 8356908
The IC is under black tape, in the image
of the underside of this R60 System board the black tape has been removed
It is much easier to
connect to the two pull-up resistor rather than the closely spaced pins
on the ATMEL 8356908

If your R60 is under Warranty cutting the
tape will most likely void your warranty, so you will need to totally
strip it down so you can carefully peel back the black tape without
cutting it.
In some of the different R60 System Board versions pictured
above, this is not easy, you will need to have the Keyboard
and LCD plugged into the system board in such a way that none touch any
contacts on the system board, use paper as an insulator to keep things
from electrically shorting out, later you will need to plug in the AC
adaptor and switch on the TP while holding 3 probes to the GND SCL and
SDA points under the system board. Do NOT switch ON the R60 now, that
will be done LATER.
See my page on Options
for Clips and Probes including making your own probes.
I receive many emails asking about the GND
connection, in reality it is very simple, you use some kind of a clip so
that you don't have to hold it in place, you DON'T HAVE 3 HANDS and there
are 3 connections, GND SDA and SCL, so have a clip for GND, then you can
use the 2 hands YOU DO HAVE to hold your SDA and SCL probes in place.
Almost any large piece of metal or the
screws for the external connectors of any ThinkPad are a good GND
connecting point.
Anyway a picture is worth a thousand words
Click

Basically
you make the System board functional outside of it's case
Once
you have taken care of the GND connection.
You
push the sharp probes onto SCL SDA , this is the reason you need 2
persons, not enough hands to hold the probes and run the software.
This is not easy, you will need to have the Keyboard
[and optionally the LCD] plugged into the system board in such a way that
none touch any contacts on the system board, use paper as an insulator to
keep things from electrically shorting out, later you will need to plug in
the AC adaptor and switch ON the TP, then you will need to hold 2 probes
in place to the SCL and SDA points on the system board.
See my page on Options
for Clips and Probes including making your own probes.
Assembling your TP - AFTER - you have finished.
Follow the Hardware Maintenance Manual [FRU System
Board], very carefully, double check screw type and size for each
individual module. Assemble the TP in the reverse order used to
dismantle it.
This page ONLY describes how to
connect the KeyMaker Interface to the EEPROM.

clear a Supervisor password are in The "User's
Guides" click here
I make no warranty that any of my
information is correct, or safe, or does or does not breach any warranty
clause, or anything else, it is up to you to decide if you will
follow all or any of the instructions to recover the Supervisor Password
from a TP. It is up to you to decide, I am not responsible for the
results or for any consequential or incidental damages whatsoever.
