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.
We also carry out motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the Lenovo ThinkPad T14s 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.
What we see on the bench
- A forgotten supervisor password is stored in a security chip and cannot be reset from software.
- ThinkPad keyboards, batteries and SSDs are accessible and well supported with parts, which makes most repairs economical.
- From the T480s onward many T-series models have one soldered memory module and one free slot.
- On the T480 and T580, USB-C and Thunderbolt charging failures are a known fault, often linked to out-of-date Thunderbolt firmware.
Data recovery from the Lenovo ThinkPad T14s Gen 4
The SSD in the Lenovo ThinkPad T14s 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.
