If your Lenovo ThinkPad X1 Extreme Gen 4 has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. It is a 16-inch laptop from 2021, identified by machine types 20Y5, 20Y6. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

What we repair on the Lenovo ThinkPad X1 Extreme Gen 4
Screen replacement
A broken 16-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
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
Most configurations of the Lenovo ThinkPad X1 Extreme Gen 4 have two M.2 slots, so a second SSD can be added, or the existing one cloned to a larger drive.
Price confirmed before work starts
Memory upgrade
Most configurations of the Lenovo ThinkPad X1 Extreme Gen 4 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 X1 Extreme Gen 4 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. On a 2021 machine a worn battery is the likely cause of short runtime, and we measure its capacity before recommending anything else.
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 X1 Extreme Gen 4, 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.
Known issues with the ThinkPad X Series and X1 range
- Memory is soldered on the X1 and recent X-series machines, so it is fixed at purchase.
- USB-C charging port wear is the board repair we see most on these.
- A forgotten supervisor password is stored in a security chip and cannot be reset from software.

The SSD in the Lenovo ThinkPad X1 Extreme Gen 4 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.
