Background and Identification
The Inspiron 15 5578 2-in-1 is a convertible laptop released by Dell near the start of 2017. As the phrases “15” and “2-in-1” in the name imply, it has a 15-inch touchscreen which can fold 360 degrees to lay flat on the back of the keyboard. Two hinges hold the two halves of the laptop together and allow for this smooth motion. The chassis of the laptop is mainly black and dark silver with both the bottom and top halves having rounded edges. As for internals, the laptop uses an Intel processor (a 7th-generation Core i3, Core i5, or Core i7 for most models) and can accept up to 16 GB of memory.
To gain access to said internals, you need to first remove the back cover by loosening the ten screws that hold it in place and undoing the plastic clasps at the edge with a spudger. The laptop has two memory slots inside and a standard 2.5-inch drive bay which can fit either a hard drive or an SSD. The battery is likewise easy to replace because it is only held down by two screws. Nice! You can find disassembly instructions for all these components—and most others in the laptop—here on iFixit or in the Inspiron 15 5578 2-in-1 service manual.
To identify this laptop, look on the bottom cover for a sticker containing either the service code or service tag. These two numbers are unique codes that you can enter on the Dell support website to find the exact name for your device.
