My daughter has an IBM R40 Thinkpad that is over three years old. This morning the disply screen began to dim and is now totally black. Even after re-booting the screen will not come on. I connected my dsktop monitor to it and the computer seems to work fine except for the display. A friend who is a programmer told me by phone it could be, the light bulb (?) for the screen has gone out. He thought it was not a simple task to replace.

When you connected the external monitor thto the laptop did it display?
If so then you have to reset the monitor port. Hold down the function key and find the FKEY that shows a picture of a monitor. Press that until you get the laptop screen back.

When I connected the laptop to the desktop monitor, only the desktop monitor would display. I tried to press the F5 key (monitor) without success.

An external monitor works fine, but my laptop screen is black. I have tried resetting the monitor port with the function key. I have tried resetting the computer by powering down and taking the battery out. Do I need to replace the LCD display or might there be some other software solution? Is there a technical website that tells how to do this? Mine is a 2005 Thinkpad R40.
