Price confirmed before work starts
Memory
Memory in the Dell Latitude 9420 is soldered and cannot be upgraded. It is worth knowing this before paying anyone for a memory upgrade.
Windows repair and reinstall
The Dell Latitude 9420 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
We replace the internal battery and check the charging circuit and adapter at the same time. A battery of this age that swells should be replaced before it damages the trackpad or casing.
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 9420 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
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 9420, 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
- A forgotten BIOS administrator password can be cleared with proof of ownership.
- The slimmer Latitude 7000 and 9000 machines trade serviceability for size, and recent generations have soldered memory.
- USB-C and Thunderbolt charging faults are the board repair we see most on these.
Data recovery from the Dell Latitude 9420
The SSD in the Dell Latitude 9420 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.
