We repair the Lenovo ThinkPad T550 at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. The Lenovo ThinkPad T550 is a 2015 laptop with a 15.6-inch screen, identified by machine types 20CJ, 20CK. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Lenovo ThinkPad T550 repairs and upgrades
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
SSD and storage upgrade
The Lenovo ThinkPad T550 uses a 2.5-inch SATA drive. Replacing a hard drive with an SSD is the biggest speed improvement available for a machine of this age.
Price confirmed before work starts
Memory upgrade
Most configurations of the Lenovo ThinkPad T550 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
Windows repair and reinstall
This model does not meet Microsoft’s Windows 11 requirements, and Windows 10 reached end of support in October 2025. We can advise on the realistic options, including a lightweight Linux or ChromeOS Flex installation.
Battery replacement
Most configurations have a clip-in battery that can be swapped in seconds. We also test the charging circuit, because an old battery is not always the only fault. On a 2015 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
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
A charger that only works at a certain angle means a worn charging socket. We replace it and test the charging circuit behind it.
We also carry out motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the Lenovo ThinkPad T550, 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 T Series range
- 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 T550
The Lenovo ThinkPad T550 has a 2.5-inch drive that we remove and image on our own equipment. If the drive is clicking or was dropped, stop powering it on: each attempt can do more damage.

Questions
Can the SSD or memory in the Lenovo ThinkPad T550 be upgraded?
The 2.5-inch drive can be replaced with an SSD. Memory is in slots on most configurations and can be increased.
My Lenovo ThinkPad T550 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 T550 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 2015 Lenovo ThinkPad T550 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.
