If you replaced the entire LCD panel, then it seems you could have (a) a bad replacement panel, or (b) a bad circuit on the motherboard that the panel plugs into. <br />

I have a T61p in the basement. That computer has a video output. Plug in an external monitor. Does the external monitor work?

The old and new LCD panels work the same. Getting a new LCD did not change anything. Sorry I should have mentioned that I can use the computer fine with the video out-plug. It is the only was i can still use the computer.

Hey all, I have been struggling to fix my Lenovo T61. One day the back-light stopped working. I experienced no warnings, it just happened. I replaced the inverter with no luck. I then replaced the whole LCD panel to still have the same problem. I checked the motherboard for any loose connections but everything looks ok. When I turn on the computer I can faintly make out whats on the screen but it is very dark. I look forward to some advice, Thank you!

My Lenovo T61 backlight is not comming on.

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.

Displays / Monitors

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
