RISOLTO: How to remove top cover from display assembly - Alienware M18x

How to remove top cover from display assembly

My LCD screen failed so I extracted the display assembly but failed to find a replacement for it but did find parts available from some disassembly outlets but only for the assembly minus the back cover. I succeeded in removing the back cover and top cover on my assembly but cracked the LCD panel when trying to pry off the top cover. I have managed to purchase and assembly minus its back cover but the top cover is not the correct one for my m18x so need a good way of prying the top cover from the LCD.

I found that the glue used to attach the LCD is so tough that using plastic prying tools does not work and as I tried and failed using metal ones need to find some way of softening the glue.

Anyone any hints for me?

Hi @mrmajorthorburn

Try a syringe filled with Isopropyl Alcohol 99%+ (available from electronics parts stores) and use it to run a line of alcohol along the LCD panel edge and the cover to start softening the adhesive.

It's a slow process as once the adhesive has softened you will have to gently pry the cover from the panel a bit at a time and then apply more alcohol to the next section that it still stuck and so on

When you finally have removed the cover, use the alcohol to clean the inside of the cover of any residual adhesive.

Once clean use thin double sided adhesive strips to secure it to the new LCD panel

Failing that here's a lid/back cover parts list that may help.

Search online for Dell (insert required part number) to find suppliers that suit you best. e.g. black cover = Dell 122RP, red cover = Dell J1C2G

Here's the service manual that may also help.
