HASSLE-FREE WARRANTY
This HP ProDesk 400 G9 system is backed by a 1-year warranty that protects you against electrical and hardware component failure. If your system encounters a hardware issue within the first 30 days, it is covered by our standard Collect & Return service for fast and hassle-free support.
After the initial 30 days, a fully qualified technician will be arranged to assess and resolve the issue at your convenience — either remotely or in-store at our London location.
If, for any reason, the system cannot be repaired under the terms of the warranty — such as unavailable parts or repair costs exceeding the device’s original value — you’ll receive a brand-new replacement of equivalent specification, ensuring minimal disruption and maximum peace of mind.
