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

Alternate connection points on some R60 models

The connection points are under black tape, in this image the black tape has been cut away

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 here for pictures of GND Connections

Basically you make the System board functional outside of it's case [ IF you had to remove the System Board ] which includes mounting heat sink and fan on CPU.

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.

The instructions on how to Recover or clear a Supervisor password are in The "User's Guides" click here
