Lenovo ThinkPad L390 Repair
We repair the Lenovo ThinkPad L390 at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. It is a 13.3-inch laptop from 2019, identified by machine types 20NR, 20NS. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Lenovo ThinkPad L390 repairs and upgrades
Screen replacement
Cracked, flickering or lined 13.3-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
Keyboard and trackpad repair
The keyboard is a separate part on most ThinkPads and is replaced without disturbing the rest of the machine. Trackpad and TrackPoint buttons are replaced the same way.
Charging port and power repair
Charging is over USB-C. A loose or dead port is replaced where it is a separate part, or repaired on the motherboard where it is soldered.
SSD and storage upgrade
The Lenovo ThinkPad L390 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 Lenovo ThinkPad L390 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 Lenovo ThinkPad L390 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. At this age, short runtime and sudden shutdowns usually point to a worn battery and not a board fault.
Price confirmed before work starts
We also carry out motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the Lenovo ThinkPad L390, 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
- ThinkPad E and L series are simple to work on, and most have a replaceable SSD and at least one memory slot.
- Plastic chassis parts around the hinges can crack on older E-series machines.
Data recovery from the Lenovo ThinkPad L390
The SSD in the Lenovo ThinkPad L390 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.

Where the Lenovo ThinkPad L390 sits in the range
Its nearest relatives in the Lenovo ThinkPad E and L Series range are the older Lenovo ThinkPad L380 (2018) and the newer Lenovo ThinkPad L13 Gen 2 (2021). Memory differs: SODIMM slots on the Lenovo ThinkPad L390, soldered on the Lenovo ThinkPad L13 Gen 2.
Questions
Can the SSD or memory in the Lenovo ThinkPad L390 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 Lenovo ThinkPad L390 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 2019 Lenovo ThinkPad L390 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 base label shows the model name and a machine type, four characters such as 20W0 or 82H8. For this model, look for 20NR or 20NS.
