Lenovo ThinkPad L15 Gen 1 Repair
We repair the Lenovo ThinkPad L15 Gen 1 at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. It is a 15.6-inch laptop from 2020, identified by machine types 20U3, 20U4, 20U7, 20U8. 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 Lenovo ThinkPad L15 Gen 1
Screen replacement
A broken 15.6-inch screen is replaced with a panel of the same resolution and finish. We check the display cable while the lid is open.
Price confirmed before work starts
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
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 L15 Gen 1 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 L15 Gen 1 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 L15 Gen 1 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.
We also carry out motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the Lenovo ThinkPad L15 Gen 1, 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.
What we see on the bench
- 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 L15 Gen 1
The SSD in the Lenovo ThinkPad L15 Gen 1 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.

Questions
Can the SSD or memory in the Lenovo ThinkPad L15 Gen 1 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 L15 Gen 1 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.
How much does a Lenovo ThinkPad L15 Gen 1 screen replacement cost?
Price confirmed before work starts. The exact figure depends on the part your machine needs, and we confirm it before any work starts.
Is a 2020 Lenovo ThinkPad L15 Gen 1 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.
