Screen replacement
A cracked or dark 23.8-inch display is replaced with a matching panel. Where the picture is there but very dim, we test the backlight and its driver before condemning the panel.

SSD and storage upgrade
The Lenovo ThinkCentre M90a Gen 3 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.

Memory upgrade
Most configurations of the Lenovo ThinkCentre M90a Gen 3 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 Gen 3 shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
We also carry out motherboard repair, overheating and fan repair, virus removal on the Lenovo ThinkCentre M90a Gen 3, 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.
What we see on the bench
- A dark screen with the PC still running is usually a panel or backlight fault.
- Lenovo all-in-ones have laptop-style parts behind the panel, and most repairs start with removing the back cover or display.
Data recovery from the Lenovo ThinkCentre M90a Gen 3
The SSD in the Lenovo ThinkCentre M90a Gen 3 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.
