Background and Identification

The Inspiron 15 3558 is a budget laptop released by Dell in 2016. It is part of the Inspiron 15 3000 series, each of which has a 15-inch screen but features different specifications. The 3558 has an Intel processor inside along with an Nvidia GeForce 920M graphics card on some models. It is made from black plastic with a dotted texture. The sides contain three USB ports (one USB 3.0 port and two USB 2.0 ports), an HDMI video output, an Ethernet port, and a headphone/microphone jack along with a tray-loading DVD drive.

Most components in the laptop are replaceable, which makes it easy to repair. The battery is swappable and comes off the back of the laptop once you released a single clasp. Similarly, the optical drive slides out from the side of the device and is held in by a single screw on the bottom case. Unlike some other Inspiron 15 3000 laptops, getting to further components of the 3558 requires removing both the keyboard and the full back cover. Luckily, Dell provides excellent instructions in their service manual. Both the memory and hard drive are upgradeable, with the laptop accepting up to 8 GB of memory and any 2.5-inch SATA hard drive or SSD (for a faster experience).

You can identify this laptop by looking on the bottom side for a sticker containing the model name “Inspiron 15 3558.” According to this Dell support article the sticker may also be located on the outside of the computer in the battery compartment. The sticker likely also contains the service tag or service code (a.k.a. the serial number) which you can enter on the Dell support website for complete information about your machine.
