Repairs we carry out on the Dell Latitude 3390
Screen replacement
We replace the 13.3-inch panel like-for-like, matching resolution and connector to the part number on the original.
Price confirmed before work starts
Windows repair and reinstall
The Dell Latitude 3390 meets Microsoft's Windows 11 requirements in most configurations. We upgrade from Windows 10, which reached end of support in October 2025, or reinstall Windows 11 cleanly with your files kept.
Battery replacement
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load. A battery of this age that swells should be replaced before it damages the trackpad or casing.

Charging port and power repair
Depending on the configuration this charges through a round socket, USB-C or both. We test the adapter, the port and the charging circuit to find which has failed.
SSD and storage upgrade
The Dell Latitude 3390 takes an M.2 SSD. We clone the existing drive to a larger one so Windows, programs and files carry over unchanged.
Price confirmed before work starts
Memory upgrade
Most configurations of the Dell Latitude 3390 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the Dell Latitude 3390, along with USB, HDMI and audio port repair, Wi-Fi and Bluetooth card replacement, webcam and speaker faults, BIOS password removal with proof of ownership and data transfer to a new machine.
Notes from the workshop
- Latitudes are built to be serviced: batteries, keyboards, screens and SSDs are all accessible and parts are easy to source.
- USB-C and Thunderbolt charging and docking faults are common on recent models and are usually repairable at component level.
- A forgotten BIOS administrator password can be cleared with proof of ownership.

Questions
Can the SSD or memory in the Dell Latitude 3390 be upgraded?
The SSD can be replaced with a larger M.2 drive. Memory is in slots on most configurations and can be increased.
My Dell Latitude 3390 will not turn on. Is my data lost?
Usually not. The drive is separate from the fault in most cases, and we can remove it and copy your files even if the machine itself is not worth repairing.
Is a 2018 Dell Latitude 3390 still worth repairing?
It depends on the fault. A battery, SSD or charging socket is usually worth doing. A major board repair on an older machine may cost more than the machine is worth, and if that is the case we will say so.
Where do I find the model number on my laptop?
The model name is on the base label or palm rest. The 7-character Service Tag on the base identifies the exact build. For this model, look for 3390.
