I have an IBM Thinkpad T60 2007 laptop with a 14-inch 1024x768 screen. Some time ago on one occasion I turned it on, Windows booted without any problems, but in the exact moment I plugged in my webcam (Logitech C905) the display went totally dim - the picture was still there but no backlight.

Could the webcam or the USB port I was plugging it into have caused this? I'm using that port all the time and it's working fine.

Since then I have ordered and changed the following components:

  • inverter (twice)
  • LCD panel
  • display ribbon cable

but neither of those has helped.

I've been using my TV as a display since the light went out and it works totally fine, but I'd really like to use it as a portable computer again.

I've run out of ideas, does anyone have anything that could help?

Sounds like the motherboard power section has failed. –  Moab Jan 7 '12 at 14:58
That doesn't sound too good, would that mean the motherboard needs to be replaced? –  Imre Kószó Jan 8 '12 at 16:11
That is my guess, unless you got another bad panel or inverter. –  Moab Jan 8 '12 at 17:01
Thanks mate, I'll have a look around if there are any system boards available then. –  Imre Kószó Jan 9 '12 at 16:18
Here is a good forum for Thinkpads, you might ask for diagnostic help there also...forum.thinkpads.com/viewforum.php?f=29 –  Moab Jan 10 '12 at 0:29
