MSI Laptop Repair

MSI GS66 Stealth Disassembly (RAM, M.2 SSD upgrade options)

Almost half of the bottom cover of MSI GS66 Stealth is covered with densely packed small holes, which serve to ensure heat dissipation. The bottom cover of MSI GS66 Stealth is made of metal, which can minimize the thickness while ensuring the stability of the fuselage structure.

In order to remove the bottom cover, we need to remove all the screws that fix the bottom cover. It is worth noting that there is a screw covered with MSI’s fragile label. If the fragile label is damaged, it means you will lose the warranty. So during the laptop warranty period, it is not recommended that you upgrade the memory and SSD yourself.
Remove the bottom cover

After removing the bottom cover, let’s take a look at the inside of MSI GS66. Its cooling system has three fans and seven copper pipes, which can ensure the stable operation of MSI GS66 at high power, and the thinner body is not prone to overheating. All the memory, solid state drives, etc. are covered with black thermal pads, which play a role in heat dissipation.

    Can someone at Best Buy do this for me without voiding the warranty?

    1. Your best bet is to contact MSI by email and ask them how you should go about the upgrade… Might take a couple of days, but they’re very nice to communicate with… The machine has to be registered in your name with them, so if you haven’t already done so, do that first…
      I say they’re very nice because they issued me a one year warranty on a non-functional MSI GE62VR laptop that i completely rebuilt using parts (motherboard and screen) that i bought on EBAY… I sure didn’t expect that…
      Take Care…
