Price confirmed before work starts
Memory upgrade
Most configurations of the Lenovo ThinkCentre M820z 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 M820z 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 M820z 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 M820z, 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
- 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.
