Screen dark: Open/Close of lid makes screen bright
My Thinkpad T22 works well except for the dark background problem. I believe that if I re-seat the data flex cable into the motherboard it may solve the problem. My problem: How do I take the laptop apart without destroying it? I have worked on PCs for 7 years however never taken apart a laptop to the level which I require. Sometimes when I start Laptop it beeps at me telling me (I beleive) the data flex cable is not seated properly. If I open/close lid it starts without beeping and screen lighted well. Thank you for your time. - Todd

I am having a problem just like this
here is a link to the service manual from ibm
copy and paste in your browser.
use egg carton or something that you can hold and label your screws or you can use a color marker to
mark the screws. different color for different screws also have good lighting
i have a dell inspiron 1000 that the lcd goes black. i am not getting any beep codes and i cant find a service manual for it.
good luck let me know if and how you fix your laptop [email protected]

Function F7 will enable the external video monitor connection and will toggle between the screen, the screen plus external monitor, and the external monitor only. Try hitting function F7 and see if that helps. Also there is a small switch that is activated when you close hte lid to turn off the display when the lid is closed. make sure that this little switch is not stuck.
It is unlikely to be the cmos battery as there are signs [music] that your laptop is booting - shine a light into the screen if you can see an image but it is very dark then it is likely that the screen backlight is not working. If this is the case the most likely causes are a faulty inverter or a faulty screen cable - both can be obtained as a kit quite cheaply on ebay if you have the ability to fit them.
