T60 T60p EEPROM you treat it as 24RF08
Locating the T60 connection points
Switch the T60 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,
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.
There are 2 possibilities with T60, different
versions of the System board.
The Easy one just below or another one further
below if your T60 does not match the easy method.
Easy method connection points are just under
the keyboard, refer to Hardware Maintenance Manual Remove Keyboard and also
Palm Rest and or Palm Rest and Fingerprint Reader.
Remove the palm rest, lift up Keyboard and put
it aside backwards while it remains connected, on the left you can see a large
LSI with the connection points for SDA and SCL, GND is connected to one of the
metal clips holding the RAM cards.
Overview, GND clip already connected, using the
KM9AUSB with Optional LCD to recover T60 SVP
The GND clip visible in the middle of the photo
This is the area of interest on the left side
under the Keyboard
SDA and SCL connection points identified
GND clip connected, SCL and SDA connection
point contacted using 2 probes
NOTE: On some T60 variants
there is a shield over the connection points just under the keyboard - thereby
forcing you - to dismantle it in order to gain access to the connection
If your T60 doesn't look like the images above,
then try the next image, the not so easy method.
note you do NOT remove the fan
Once you have your HMM search the manual for
"Removing and replacing a FRU" then scroll down to 1200
System Board, it's on Page 97 of the manual, 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 underneath the
intel 82801GBM as illustrated below.
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 T60 now, that will be done LATER.
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
here for pictures of GND Connections
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.
This page ONLY describes how to connect
the KeyMaker Interface to the EEPROM.

clear a Supervisor password are in The "User's

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
