Dell Latitude 3400 Repair
If your Dell Latitude 3400 has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. The Dell Latitude 3400 is a 2019 laptop with a 14-inch screen. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Repairs we carry out on the Dell Latitude 3400
Screen replacement
Cracked, flickering or lined 14-inch screens are replaced with a matching panel. Where the picture comes and goes as the lid moves, we check the display cable and hinges first.
Price confirmed before work starts
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 3400 takes an M.2 SSD. We clone the existing drive to a larger one so Windows, programs and files carry over unchanged.

Memory upgrade
Most configurations of the Dell Latitude 3400 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
Windows repair and reinstall
The Dell Latitude 3400 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
A new internal battery is fitted and tested through a full charge and discharge. A battery of this age that swells should be replaced before it damages the trackpad or casing.

Data recovery from the Dell Latitude 3400
The SSD in the Dell Latitude 3400 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start. Recent Windows machines often have device encryption or BitLocker switched on. If so we will need the recovery key, which is normally saved in your Microsoft account.
