Laptop LCD Problem

Mar 17, 2008

- Hey, good news dudes. I finally fix it!!! It's easy to solve but it's a little bit tricky to open the notebook screen. I'll try to explain what I've done to fix that problem.(Sorry for my english,I'm still learning)
THIS IS THE HOWTO'S FIRST PART, TO BE CONTINUED IN A FEW HOURS. NOW IT'S TIME TO GO TO CLASS.SEE YA.
First of all, remember that the problem in my HP Compaq NX5000 was in the screen, because everyday had the same stupid trouble: the screen seem to switch off and switch on like a damaged bulbe light or neon tube,randomly, even if you don't touch the screen at all or move the laptop. So, I decided to dismantel my laptop, to search a bad contact between the laptop's mainboard and the TFT screen, because I suposed this probably was the problem. Here's a little HOWTO, only suggested to experienced people, because is easy to break plastic pieces from laptop if you aren't experienced enough.
0.Take a good place to operate, a good table, good lightning and a good set of screwdrivers and a empty cup or something like that to contain all the screws that you remove (They are too small and it's easy to loose them)
1.Remove all power supply and battery cell from laptop.
2.Touch the ground to discharge all static electricity that your body can store, avoiding high power discharges over the hardware.
3.Now you must remove a set of screws from laptop's behind side: those labeled with a keyboard sign and specially all near power supply plug(3) and around USB and VGA connectors(+3). Those are the most importants because when we take off that screws, we can release 3 components to start the job.
Now, open the laptop and using a plane screwdriver or something like that,trying to release the silver plastic piece that contain the switch buttons (power,wifi).Use the screwdriver in the slot between black and gray parts to help in the extraction of the gray section(remember,only the buttons container).Be careful on break that piece becasue it's fragile, and if you expect that will broke, test again the screws that you must already removed.(this must be a constatn checking in all the process:Don't force plastic, be patient and check all screws).
4.It's time to release the keyboard, so take care with this: the keyboard is connected to the mainboard by a special membrane connection. To release that membrane, where it's conneted to the mainboard, you must locate a plastic piece that acts like a secure to avoid accidental switch off. Pull Lift this piece of plastic.If you have released the marked screws, the keyboard is loose and you can easily pull off.
