Locating the eeprom

Using the TP 600e Hardware Maintenance Manual and your nice small Philips screw driver, dismantle the TP

Follow the Hardware Maintenance manual "FRU System Board" to dismantle your TP and gain access to the underside of the System Board where the 24RF08 eeprom is located.

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

The 600e has 2 EEPROMs, one is a 24C01 located near the Flash BIOS, this eeprom does NOT contain any passwords,  leave it alone.

The other eeprom is located on the other side under the PCI made by Intel, it is a 24RF08 this eeprom contains the Supervisor Password and the Hard Disk Password.

 

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

This image is of the same type eeprom in another model TP, it illustrates which eeprom pins you solder the 3 wires to.

 

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.
