IBM ThinkPad R40 wont power on was on left room seen it just start to say entering hybernate as I was comming back in the room. It has 2 light on the battery light and the light just right of the battery that looks like a sidways Z. According to IBM site that light indicated the computer is on and running. I hit the caps key and nothing the display is blank. Hold power buttion down for 30 seconds light go off. Rewmoved battery power coard and left for 4 hours nothing so did it again but removed the internal cmos battery too left for 24 hours nothing. If I put in a bootable cd in the drive and turn it on the cd will spin up and then down and change speeds several time but nothing. I connected an external disp to pc and nothing there either. Help I love my little R40 was given to me when I lost every thing from a best friend.
Sorry should of given more info when that happened the unit was running off of power adapter. The battery light is Greennot orange.

remove the battery and adapter. press power button for 30 sec. then connect the adapter. press power button. if this didnt work. you need to ask for an help of a local tech to check for the video card and cable.
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.
This could be a battery problem. Remove the battery and start on the power supply only. If this doesn't work, then check the power supply with an ohm meter to see if it's getting the proper output to the machine. If the supply checks good, then I'm afraid that you have a problem component on the motherboard, and will need to have it professionally diagnosed in order to track down the exact problem component.
Batteries can develop a dead short and cause a no start. Try starting without the battery. Other things you can try is checking the power supply with an ohm meter,or plug it in and stick it in your mouth, but me personally, I'd use the ohm meter. Also check the memory, a faulty memory chip can cause this. If none of these work, them I'm afraid the problem may be with the power management chip on the motherboard. If the pm chip is malfunctioning, then motherboard replacement is your only option.
