Yeah, that does not sound good. Does this also happen if you first switch to a text console, (CTRL-ALT-F1) and shut down from there? What drivers are you using for that ATI chipset? The bottom is where the back-light tube is. This is a florescent tube about as big in diameter as a toothpick and 13.3" long (in your case). Very fragile. It sounds like this tube is getting over-driven pretty severely. This can shorten the backlight's life quite a bit. The tubes are not particularly expensive (about $12) but putting them is is a real pain in the neck. There is a high voltage supply in there too, and it may be part of the problem. The LCD itself is likely not involved in this, just the backlight is my guess. -- _____________________________________ John Andersen
