We repair the Lenovo ThinkBook 14s IWL at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. It is a 14-inch laptop from 2019. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Lenovo ThinkBook 14s IWL repairs and upgrades
Screen replacement
We replace the 14-inch panel like-for-like, matching resolution and connector to the part number on the original.
Price confirmed before work starts
SSD and storage upgrade
The Lenovo ThinkBook 14s IWL takes an M.2 SSD. We clone the existing drive to a larger one so Windows, programs and files carry over unchanged.

Memory upgrade
On most configurations of the Lenovo ThinkBook 14s IWL, part of the memory is soldered and there is one free slot, so it can be increased but not replaced entirely.
Windows repair and reinstall
The Lenovo ThinkBook 14s IWL 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. On a 2019 machine a worn battery is the likely cause of short runtime, and we measure its capacity before recommending anything else.

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.
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 Lenovo ThinkBook 14s IWL, 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
- USB-C charging faults are the common board repair.
- ThinkBooks combine consumer-style chassis with business features; most have a replaceable SSD, and memory is part-soldered on many.
Data recovery from the Lenovo ThinkBook 14s IWL
The SSD in the Lenovo ThinkBook 14s IWL 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 ThinkBook 14s IWL be upgraded?
The SSD can be replaced with a larger M.2 drive. Part of the memory is soldered, with one slot free on most configurations.
My Lenovo ThinkBook 14s IWL 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 ThinkBook 14s IWL 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 14s.
