Question about IBM ThinkPad R40 2722 Notebook
I got a IBM ThinkPad R40 off ebay. The laptop looks almost new accept for a crack on the front of the touchPad on the palmrest and missing the screws to hold the laptop together. I own a IBM ThinkPad T40 and bought the R40 just for games. I used the T40 AC Adapter on the R40 and press the power button and no power on, no fan or lights. The laptop is missing the CD Drive, Battery, AC, RAM ,Hard Drive cover and built-In WiFi adapter card. I fixed a IBM ThinkPad R31 along time ago with the same problem, I don't know if its because it don't have RAM in it or not. Some laptops will not turn on without RAM. Unfortantly I don't have any DDR RAM laying around only the old types like DIMM for the T20 series. So can't test RAM thought.
If the the ram is the problem of your system, there should be a power on light on the system. indicating that some of the component of the system is not working correctly. But since you mentioned there is no light, it is the possibility that the problem is the motherboard itself.

I have the 380z and the display quit. It lights up with streaks buts thats it. well it has a spot for an external monitor so i plugged one in. System does boot up and works for with an external monitor. If you indeed think you have a ram problem try this step first,it just might be your display!!!
