Re: ibm thinkpad r40
This could be a problem with the battery, try removing the battery and starting on the adapter only. If this doesn't work, then I'm afraid it is going to be a motherboard problem, most likely with the power management system, this is the most common area with this type of problem. You can take it in for diagnostics, but I'm afraid you're going to end up having to replace the motherboard in order to fix the problem.

The problem youve discribed does seem to point to your back light has failed on the laptops lcd display, i dont know exactly how this would accure just using a projector though, go into bios again and try loading factory settings.
This problem could also be the inverter if you cant make out even a slight image on the screen.
The IBM beep code error 1 long 2 short beeps means there is a video card fault. Reseat your RAM because the video card uses some of the RAM. If it doesn't work then the video chip on the motherboard is faulty, the only way to fix is to replace the motherboard - this may not be a cost effective solution.
Connecting an external monitor to the laptop won't work because the video card also sends data to the video port.
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.
According to system specs your system is not compatible with the Core 2 Duo or Centrino Core 2 Duo. To upgrade to those chips you would need to replace the motherboard with one capable of running those chips. If you decided to do that you would almost surely need new RAM as newer boards use newer technology. By the time you did this the upgrade would not be cost effective. Hope this helps & please remember to rate my answer. Thanks.
is the windows cd for ibm specifically? if not then you will need: a sound card driver (optional) a graphics card driver (optional) a cd rom driver (maybe) drivers for usb ports (optional) and any other drives/ input devices on your laptop will need drivers. when formatting bear this in mind. All data will be lost! proceed knowingly and with caution. one mess up will land you in problems up to your shoulders! i recommend finding out how to do it safely
