Hi everyone, welcome to HowFixit. In this video guide, I will show how to replace
motherboard on Alienware 15 R4 laptop To disassemble Alienware 15 R4 laptop,
you will need the following tools: Phillips 1 screwdriver
Plastic opening tools Tweezers
Antistatic brush Thermal grease
I also recommend using a magnetic mat during the repair process, which is especially useful in case
of this laptop. Throughout this disassembly, keep track of each screw so you can put them
back in the right places - this will help successfully reassemble your device. And
don't worry about losing any of screws, all of them will definitely remain on the magnetic mat.
