    do the Cpu's of the 920xm users with clevo laptops have also the orange protective film? I ended up removing mine since i thought it was just there to protect the cpu from the air transit butI later realized that it is factory applied to other 920xm cpu's.

    Can anyone confirm?

    Isnt it there just to make application of themal paste easier in a way that conductive thermal paste does not touch the substrate? BTW some GPUs also have this protective film - I removed it when I replaced my 8600M GT after it failed with a MR HD 3650 and it had no effect whatsoever. I think other than that the film does not serve any purpose and can be removed without harm.

    I would leave it on if possible. It's there to protect the capacitors and exposed traces from possible shorting from the thermal grease. As you know some thermal greases can have electrically conductive properties. (arctic silver comes to mind). If Intel is putting it on they have a reason that may not be so obvious to the rest of us. The stuff is Kapton tape, I use it at work for various reasons on printed circuit boards. It's insulative type of tape.

    Well yeah I understand that but I never thought that this was "factory" applied. I thought Alitunay just put this film on purpose when he sold it to me here in NBR Marketplace. The GPU dies have black protection films and they follow the shape of the substrate perfectly (without any excess or lacking in the edges) unlike this orange protective film which was like just put there by somebody intendng to protect the CPU in its packaging or something.

    And what I'm confused at is most Clevo 920XM users do not have that film right? Cna somebody confirm this?

    All the OEM CPUs have the film unless someone ripped it off ... All the ES 920s i have seen do not have it ..

    If your laptop is running fine I would not worry about it. You risk more problems taking apart your laptop to put that back on, versus the benefit of having it on. Just leave it on next time if you see that in the future. In other words relax and enjoy your laptop.

    Just use thermal paste that is not electronically conductive and you don't have much to worry about.

    Yup I was just very curious if that film serves a special purpose but in the end it may just be really there for protection and at the same time for EMI shielding.

    Its there for protection only, there is no EMI shielding going on. To shield it needs to be electrically conductive and at some point make a connection to ground.

    Here is a site that sells the stuff, it has brief descriptions on its properties. If it is of any interest to anyone.

    Kapton tapes, Polyimide Tapes
