Question about Dell Computers & Internet
Hi, i disassembled an N5040 laptop, for LCD panel replacement, so i did an extensive deep cleansing for all the parts. when i removed the heatsink, i there was a black rectangle material of some sort, surrounding the edges of the thermal compound residue. when i cleaned it (with alcohol), the black material, which was slightly resembling a sticker, was removed also.. first of all, what is that black material? is it necessary? (or i can ignore it while reassembling). if so, how can i replace it? P.S Im not talking about the thermal compound, i know i must replace that..
The black material can be a insulation sticker though u don't have to worry a lot about it .... Ignore it

Thanks Steel Breeze!! I did exact as you suggested and it was easy. I used a Dremmal tool to cut a squre holes. You can actaully see part of the battery (CR2032) through one of the existing holes.

Walk into a Computer hardware shop. Of course they will have all the required tool to open the laptop up and fix the new screen.

Here is one place I found thru google that sells your lcd for your laptop:
Price is about $89.00 before any S/H charges. I'm sure if you do some research you may find them cheaper.
When it comes to replacing the lcd on these laptops most of the time its done the same way. Unscrew the screws on the front lcd bezel and then remove the bezel so it will expose the lcd with a hinge on each side.
Remove the screws on the left hinge and also remove the screws on the right hinge.
At this point the screen will be loose. Disconnect the power connector from the bottom of the lcd that goes to the little rectangular inverter board.
There will also be a cable on the back of the lcd screen that needs to come out as well. Be gentle with the cable cause its sensitive.
At this point you can remove the bad lcd and then get ready to put the new lcd into place.
Go ahead and connect the lcd cable to the back of the lcd, don't worry it is slotted so it can only go in one way and it will kind of snap into place. Then go ahead and align the screen with the left and right hinges so you can put the screws back on so it keeps the screen in place.
Then go ahead and connect the power connector to the rectangular inverter as well. Now that you have the screen hooked up. Turn on the laptop and if you get video then you know the screen is good, turn the laptop back off and then go ahead and put the lcd front bezel back on and put the screws back into place and you should be good to go. I know this was lengthy but hope this information helps.
