Actually its a minor problem. The screen flickers if I move it, occasionally. I can adjust it and it works but I know that the connector is failing. However Best Buy are a bunch of turds on this problem and want to send it away for 4 weeks. Like most of you 4 weeks is too long to be without my baby...anyway, is it difficult to fix this issue? Is it soldered (sp) or is it a pin connector to the mobo? THey tell me its soldered to the mobo, hard to believe but possible. Any help would be great.
Ok now about hardrives, has anyone upgraded to a faster one? The 7422 comes with a sluggish 4800 and Im ready to move up. Again any help, advice, or guidance is much appreciated.
The calvary has arrived! LCD screen flicker repair:
Here's how it works: there are two cables that you need to worry about. One cable is between the motherboard and the inverter (the inverter is an electronics board for the LCD). The other cable is between the inverter and the LCD. The inverter is located in the lid underneath the LCD panel (it's just a green strip; you'll see it in the pictures below). There are is a plug going into the inverter from each wire. Two plugs, two wires, one inverter - with me so far?
Over time, those connectors get loose (due to poor design) and thus give you flicker. Occasionally the inverter is bad, but from what you described, it sounds like your problem is that the plugs are loose.
The way to solve the loose plugs issue is to secure the plugs to the lid chassis so that they don't move. My solution for that is hot glue. I actually stole the idea from Compman55, but modified it slightly. To begin, you will need to disassemble your LCD monitor. This sounds scary, but it isn't that hard. Note that this will probably toast your warranty, so you're on your own if anything goes wrong. Here is a guide that shows you how to disassemble the LCD:http://emachines.fizi.ca/guides.php?ID=2
Next, cover the LCD with a piece of paper and warm up your hot glue gun (you can buy mini hot glue guns from Radio Shack for a few dollars). The paper is to protect the LCD just in case you mess up and spill the hot glue. Here's the procedure:
1. First, push both connectors into the inverter securely.
2. Second, position the wires such that there is enough slack for them when you open and close the monitor. You can test this out by putting your finger against the wire and the lid chassis and moving the LCD back and forth. If it's too taut, the wire will slip out from under your finger.
3. Once you have it where you want it, cover the connector (the one going into the inverter) and the wire near the connector with hot glue. You may have to hold it with a toothpick or something until it dries. Do the same to the other connector; both connectors going into that middle inverter should be hot glued. When it's dry, test it out to ensure that it works well - it should hold the wires in place and allow enough slack to fully open and close the monitor without any strain. Here are some photos of the hot glue on the wiring in my thread about my flicker fix:http://www.notebookforums.com/showth...hlight=flicker
You can take a look at a short video of the hot glue technique in action here:http://www.wiredbynature.org/gateway/flicker/hinges.wmv
I have been flicker-free ever since I completed this procedure. The monitor looks and works great. From the sound of it, this should do the trick for you, too.Hard drive upgrade:
Hard drives come in three speed flavors: 4200rpm, 5400rpm, and 7200rpm. The fastest available are 7200rpm hard drives; they only cause you to lose about 4 minutes of battery life compared to 4200rpm drives according to tests. Hitachi and Seagate currently make 7200rpm laptop hard drives. Hitachi offers a better value because (1) their drives are second generation, (2) their drives are cheaper, and (3) their drives are available in a wider variety of capacities. You can get a 7200rpm Hitachi hard drive in 60gb, 80gb, and 100gb varieties. The model number to look up is "7k100", the Hitachi TravelStar drive.
I actually just purchased a 100gb 7200rpm Hitachi hard drive. It dramatically improved boot time and also makes programs open faster. I got the drive for under $200 shipped. Good online sources to buy from include Newegg.com, ZipZoomFly.com, and Buy.com. I wrote an article on how to upgrade the hard drive, available here:http://www.wiredby.com/comp/gateway/hdd.php
The hard drive is much easier to upgrade than fixing LCD flicker. It takes about five minutes and you only need a screw driver. You can read my post about the drive and the upgrade procedure here:http://www.notebookforums.com/showthread.php?t=141374
You can also put your old hard drive in a USB/Firewire case to use for backing up your system and storing files. See the link above for a link and more information.
If you have any questions, feel free to ask. Good luck!
