Having problems with your IBM ThinkPad T40 2373 Notebook ?

T40 IBM Think pad turns on, green lights in front turn on and the fan turns on but the screen stays black. Does this mean the screen is bad?


Answers :

Hello.

Test by connecting an external monitor.

If an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim rather than a slow degradation, the inverter would be indicated.

Hope this helps.

Hi I have a compaq fs7600 pc. For the past few weeks I have been experiencing sudden "black screen" and then my hard drive shutting down. Or it will go black screen and my hard drive will beep. It is usually one fairly long beep, then repeats about 3 or 4 seconds later. I only have 512mb of ram, which came with pc. I plan on buying a 2g of ram next week. Will that solve this problem?
