    IBM 2648 t-23 has a blck screen with a humming can you help their is a little white at the top of the screen

    Screen light doesn't come on at Power Up. I have to wiggle a latch on the bottom of LCD, next to an opening which I believe is for the lamp. The screen eventually lights up so it's not the lamp. Don't know how to access the insides of this machine and don't understand either of the posted solutions. Thanks.

How to remove the display on IBM T21 laptop


The laptop screen is secured to the laptop with screws at the hinges.
There are usually two screws per hinge. The LCD screen has one ribbon cable and possibly a power connector for the back lighting attached to the motherboard near the hinges. Disconnect these before you lift the LCD off the base, they are under the plastic panel above the function keys next to the hinges.
