Lenovo ThinkCentre M90a repairs and upgrades
Screen replacement
The 23.8-inch panel is the front of the whole machine. We replace cracked, dark or lined panels and check the backlight circuit, because a black screen on an all-in-one is not always the panel.
Price confirmed before work starts
Memory upgrade
Most configurations of the Lenovo ThinkCentre M90a 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 ThinkCentre M90a 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.
SSD and storage upgrade
The Lenovo ThinkCentre M90a has an M.2 slot and, on some configurations, a 2.5-inch bay. Machines that shipped with a hard drive are much faster once moved to an SSD.
Price confirmed before work starts
We also carry out motherboard repair, overheating and fan repair, virus removal on the Lenovo ThinkCentre M90a, along with stand repair, no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
Notes from the workshop
- Lenovo all-in-ones have laptop-style parts behind the panel, and most repairs start with removing the back cover or display.
- A dark screen with the PC still running is usually a panel or backlight fault.
Data recovery from the Lenovo ThinkCentre M90a
The SSD in the Lenovo ThinkCentre M90a 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 ThinkCentre M90a be upgraded?
The M.2 SSD can be replaced, and some configurations also have a 2.5-inch bay. Memory is in slots on most configurations and can be increased.
My Lenovo ThinkCentre M90a 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 2020 Lenovo ThinkCentre M90a 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 all-in-one PC?
The model is on a label on the back, side or underside of the machine. For this model, look for M90a.
