Intel NUC 11 Pro NUC11TNHi5 repairs and upgrades
Power supply repair
A mini PC that shows no signs of life often has a failed external power adapter. We test with a known-good adapter before looking at the board.
Windows repair and reinstall
The Intel NUC 11 Pro NUC11TNHi5 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 Intel NUC 11 Pro NUC11TNHi5 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
Memory upgrade
Most configurations of the Intel NUC 11 Pro NUC11TNHi5 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
We also carry out motherboard repair, overheating and fan repair, virus removal on the Intel NUC 11 Pro NUC11TNHi5, along with no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
Known issues with the Intel NUC range
- The H in the model code means the taller case with room for a 2.5-inch drive; K is the slim case without one.
- NUC mini PCs use laptop-style memory and M.2 storage, with an external power adapter.
- A NUC that appears dead often has a failed adapter, not a failed board.
Data recovery from the Intel NUC 11 Pro NUC11TNHi5
The SSD in the Intel NUC 11 Pro NUC11TNHi5 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 Intel NUC 11 Pro NUC11TNHi5 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 Intel NUC 11 Pro NUC11TNHi5 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 do I get my Intel NUC 11 Pro NUC11TNHi5 to you?
Bring it to our workshop at Unit 1 The Willows, 80 Willow Walk, London SE1 5SY, or call 020 7237 6805 to ask about courier collection. We confirm the price before any work starts.
Can you upgrade the graphics card in a Intel NUC 11 Pro NUC11TNHi5?
In most cases, yes. We first check the power supply, the physical space and any manufacturer-specific connectors, then fit and test the card.
