Thats alright, I think I forgot about this Q around the same time ;-)<br />
Changing motherboards in a laptop just to test an issue like this is so time consuming, but that looks to be where you're at on this issue.

I've had 3 notebooks in shop recently that had no display --&gt; not even a faint one. Additionally, there was no display on an external monitor for 2 of them. All powered on and went through at least some POST sequence (removed memory and they beeped). Two Compaqs and a Toshiba.<br />
<br />
My experience with notebooks is somewhat limited but assume that inverter and/or backlight failure is not the cause. Those with no external display would appear to be motherboard or graphics adapter related (integrated graphics).<br />
<br />
Looking for assistance from notebook experts in determining root cause. Thanks in adavance.<br />

Notebook Blank Display Cause

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.
