Hardware Maintenance Manual - ThinkPad T40, T40p, T41, T41p, T42, T42p

The 24RF08 eeprom is located right under the network card, which is under the mouse touch pad, very simple to open, and very simple to locate the eeprom as well.

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

NOTE: you may have another eeprom installed at location U3, that other eeprom may be a 93C46, just ignore it.

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 or partially re-assemble your TP [depending on your chosen connection method] 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.
