If your Lenovo ThinkBook 15 IML has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. The Lenovo ThinkBook 15 IML is a 2019 laptop with a 15.6-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 Lenovo ThinkBook 15 IML
Screen replacement
Cracked, flickering or lined 15.6-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
Windows repair and reinstall
The Lenovo ThinkBook 15 IML 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. At this age, short runtime and sudden shutdowns usually point to a worn battery and not a board fault.

Charging port and power repair
We replace worn charging sockets and repair USB-C ports and charging circuits at component level. The adapter is tested first, because it is the cheapest thing to be wrong.
SSD and storage upgrade
The Lenovo ThinkBook 15 IML 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
On most configurations of the Lenovo ThinkBook 15 IML, part of the memory is soldered and there is one free slot, so it can be increased but not replaced entirely.
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 15 IML, 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
- 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 15 IML
The SSD in the Lenovo ThinkBook 15 IML 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 15 IML 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 15 IML 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 15 IML 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.
