Sometimes you fix things, and they don't turn out fixed. This is one of those stories.
I have this old Thinkpad T60 (circa 2004 - they built these things well), where windows finally gave up the ghost on this fellow, so I put on Ubuntu, but it consistently had issues with the screen - after a few minutes of operation the backlight would go out. I thought that the screen power inverter might be the problem.
It wasn't, but it was still a fun replacement, so I thought I would share:
|Screw locations - four on the front and a few on the sides.|
They're hidden behind small black covers, you can use a flat
screwdriver to pry them off.
|Here we are with the screws removed, you can pull up on the|
screen-front to reveal the power inverter - the green and
white strip at the bottom.
|It pulls right out and you can swap it with the new one.|
One side connects with the screen, and the other with the chassis
