This laptop is not very difficult to repair. Once the back panel os removed, the laptop components are easily accessible.

One downside to repairability is that the CPU is soldered directly to the motherboard. This means neither the CPU nor the motherboard can be replaced without replacing the other.

Identification

The Dell Latitude 5420 has "Latitude 5420" etched on the bottom cover of the laptop. Flip your laptop over and check for this engraving at the center of the bottom cover.
