------ T61 ------

You need to access the 8 pin chip U200, a P24S08 eeprom which is located underneath the system board as illustrated below.

The P24S08 eeprom is located underneath the system board as pictured below.

Keep individual modules and their screws separate to make it easier to re assemble it correctly

he eeprom is a Philips P24S08 which is equivalent to a 24RF08, so any reference in the following text to a 24RF08 applies to this eeprom

NOTE: VCC is NOT connected, the ThinkPad supplies power to the eeprom later on we will switch on the TP to analyse the eeprom.


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.
