Stupidest HDD location EVER! You have to fully disassemble your device for the simple operation.

Who the !&&* designs a hard drive location that requires complete disassembly of the motherboard and the laptop to replace. Horrible, horrible design.

It’s possible to skip removing the display and the WLAN card, which saves a bit of time and trouble. I think I understand why this guide and Dell’s user guide recommend removing these parts, it makes other steps a little easier, but I didn’t find it was worthwhile.

I’ve done this upgrade twice now, and I think the iFixit Opening Tool (along with the spudger) makes this job easier. Besides releasing latches for the palm rest and the memory door, it was very helpful to pry up the System Board from the Input/Output Panel.
