Power Supply
If the power-on indicator is not on and the power supply
fan is not turning, check the power cord for continuity and
correct installation.
If the power cord is not the problem, either the power
supply is defective, or another component is defective
causing the power supply to cut off. To verify that the
power supply is operating correctly, do the following:
1. Power-off the computer and disconnect the IBM
ThinkPad Dock I power cord.
2. Remove all internal and external devices, and the
computer from the IBM ThinkPad Dock I.
3. Undock the IBM ThinkPad Dock I.
4. Remove power supply connector 1 from the riser
card.
5. Install jumpers between pins 1 and 10, and pins 3
and 8 on the main card.
