Dell Inspiron 17 3780 certainly does feel a little bit dated. However, it is rather easy to dig inside. You just need to take care of something, that is rarely seen on a modern laptop.
1. Remove the bottom plate
If you haven’t figured it out yet, we were talking about the DVD optical drive. There are a couple of screws you need to undo before you pull it away from the chassis. Then just continue with unscrewing everything you see, and you are free to pry the bottom plate up.
2. Battery and storage
Most of the bottom side of the body is taken by the battery and the storage devices. Fist, you would want to unplug the battery, so you don’t accidentally damage something while disassembling. After that, remove all four Phillips-head screws, located at the edges of the 42Wh battery. On both sides of the battery, you can see the storage options – a SATA slot on the left and an M.2 PCIe slot on the right.
Memory-wise there are two RAM DIMMs that support up to 32 GB of DDR4 memory.
4. Cooling system
Cooling is realized by the classic single heat pipe and fan design. Nothing special here, but it seems to be enough for just the CPU itself.
