If your HP Z2 Mini G4 will not start, shows no picture, runs hot or has become slow, we can diagnose and repair it at our Bermondsey workshop. It is a workstation from 2018. Parts are matched to the exact chassis, so the model number matters when we quote.

What we repair on the HP Z2 Mini G4
Power supply repair
We test and replace failed power supplies. Many branded desktops use a manufacturer-specific unit, which we match to the exact chassis.
SSD and storage upgrade
The HP Z2 Mini G4 has room for SATA drives and, on most boards, an M.2 SSD. The usual upgrade is an SSD for Windows and programs with the old drive kept for storage.
Price confirmed before work starts
Memory upgrade
The HP Z2 Mini G4 uses standard desktop memory. We check the board’s limits and fit matched modules.
Overheating and fan repair
Overheating and noise are usually dust or a failing fan. We clean the system, replace what has failed and check temperatures under load.
Windows repair and reinstall
The HP Z2 Mini G4 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.
Graphics repair
We diagnose and replace failed graphics cards, and check that the power supply and case can take the card you want before an upgrade.
We also carry out motherboard repair, virus removal on the HP Z2 Mini G4, along with 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
- Power supplies and motherboards are specific to the chassis on most workstation towers, so we match parts by exact model.
- Workstations often carry several drives, sometimes in RAID, and ECC memory. Tell us the configuration before any storage or memory work.
Data recovery from the HP Z2 Mini G4
Desktop drives are removed and imaged on our own equipment. If the HP Z2 Mini G4 has more than one drive, or a RAID array, bring the whole machine so we can see how it was set up.

Questions

Drives can be added or replaced. Memory uses standard slots and can be increased.

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.
Can the HP Z2 Mini G4 run Windows 11?
Yes, in most configurations.
