Yes, that is a good video for resolving such an issue....with one major exception. When a person is going to work on a computer, they would be wise to turn the computer off before doing anything to the computer. If it is a desktop, turn it off and then unplug from the wall outlet before making a repair. If it is a laptop, turn it off and remove the battery. When repairs are completed on the desktop, plug back into the wall outlet and then turn the computer on. When repairs are completed on the laptop, re-install the battery and then turn the computer back on. For some people this may seem like elementary information, but for others this information is not known. I would say that if that young man in the video works on his computer enough times with the power on, he will probably experience ESD (ElectroStatic Discharge) and will be headed to the store to purchase a new motherboard.

Does anybody have a clue what might be causing this? Sounds like the backlight is bad, it's a little lamp that's located in the lower backside of the screen that lights up the screen. Search google for lcd backlight to learn more. There is another component that could be a problem, but the name escapes me now. Good thing you don't have dead pixel lines, that would mean a screen replacement, very expensive. Good thing you have the extended warranty.

She brought it over and the LCD was completely undamaged. In the corner, it was slightly separated from the frame. The frame was damaged a bit, bent so that the corner of the LCD would not "snap" into place. It would stay in place if we held it with our fingers, but wouldn't be secure. There's also a dent in the base by the keyboard (same corner when it's closed), but that's cosmetic. I turned it off, pried the corner of the frame a bit and snapped the LCD back into place. We both heard it snap in and I could feel it make the connection. To be on the safe side, we used some clear packing tape. You can certainly see the tape, and if you look from certain angles, you can see that it's not quite square, but all in all, it's in pretty good shape. When she called, I thought the repairs would be a couple of hundred dollars if I did them myself, so I'm VERY relieved that it was so easy to fix. And I'm also relieved that my daughter, a senior in high school, didn't insist that we needed to replace the entire case since it no longer looked new.

One of the best ways I have found to combat this, especially with a laptop, is to wear a pair of those skintight latex gloves that one can get by the boxful/drugstore...futher, when removing modules such as memory or mini pci cards, grasp then between to fingers on the edge and keep fingers off of the face and back where the electronic components are..stay away from carpeted areas and use eg kitchen table Here is a link that might be useful: ESD-Electro static discharge
