HP EliteDesk 800 G2 Repair — your questions answered
How much does it cost to repair an HP EliteDesk 800 G2 that won’t turn on?
Power issues are usually the PSU or motherboard capacitors. A full diagnostic is free; if the PSU has failed we quote $180-$260 for replacement. If capacitors need work the range is $220-$320. You only pay if we fix it and receive a 90-day warranty.
Can you upgrade my EliteDesk 800 G2 with an SSD and more RAM?
Yes. We fit a 500 GB or 1 TB SSD, migrate your data and install 16 GB DDR3 RAM. Typical cost is $240-$380 for the SSD job or $95-$145 for RAM alone. The machine will boot faster and feel like new without buying a replacement.
Is the HP EliteDesk 800 G2 still supported for Windows 11?
Officially it is not on Microsoft’s supported list, yet we perform a clean Windows 11 install after bypassing the TPM check with Rufus or via registry edits. All drivers remain available from HP and the machine runs well for everyday office and browsing tasks.
How long does a typical repair take on an EliteDesk 800 G2?
Most jobs are completed the same or next business day once parts arrive. Capacitor work or data recovery can take two to three days. We always ring with an exact turnaround time after the free diagnostic.
Do you offer onsite service for the HP EliteDesk 800 G2 in regional Australia?
Yes. Our technicians travel to homes and offices across capital cities and many regional centres. Remote diagnostics are also available if you prefer not to wait for a visit. All work carries the same 90-day warranty.
