T30
EEPROM you treat it as 24RF08
Locating the T30 connection points
Switch the T30 OFF.
You should have downloaded the hardware Maintenance
Manual already, if you have not done so,
Download and save to your PC the T30
Hardware Maintenance Manual from my TP
HM Manuals page
The eeprom can be accessed underneath the
TP by removing the RAM expansion cover and the RAM Module if fitted.
NOTE: VCC is NOT connected, the ThinkPad
supplies power to the eeprom later on we will switch on the TP to analyse
the eeprom.
The photo below shows a 24RF08 EEPROM from a DIFFERENT
MODEL ThinkPad with the Pomona clips attached to SCL and SDA pins.
See my page on Options
for Clips and Probes including making your own probes.
Assembling your TP
You need to re-assemble your TP as you will have to have it
switched ON and running to read the eeprom.
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.

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

incidental damages whatsoever.
