HP EliteDesk 800 G3 Repair — your questions answered
How much does it cost to repair an HP EliteDesk 800 G3 that won't turn on?
A no-power fault is usually the internal 180 W or 240 W PSU. Replacement parts cost $80-$110 and labour is $65-$85, giving a typical total of $145-$195 with same-day service available in most capital cities.
Can you recover data from a failed SSD in my EliteDesk 800 G3?
Yes. We clone the existing NVMe drive to a new module in our workshop using hardware imagers when the original drive is still partially readable. Pricing starts at $180 and includes the new SSD; unrecoverable drives are quoted separately.
Is it worth repairing an eight-year-old HP EliteDesk 800 G3 or should I buy new?
If the fault is limited to PSU, SSD or RAM the repair cost is usually under $250 and the machine will remain productive for another three to four years. A full motherboard replacement at $320-$420 is closer to the price of a refurbished newer model, so we advise case-by-case.
Do you offer onsite repair for HP EliteDesk 800 G3 desktops in regional Australia?
Our technicians travel to most regional centres within 200 km of capital cities for a $45 travel fee on top of the repair cost. Remote diagnostics via TeamViewer are free if the machine will still boot to Windows or a USB stick.
Will replacing the SSD void any remaining warranty on my EliteDesk 800 G3?
These machines are long out of HP warranty. Adding or replacing an M.2 SSD is a standard, reversible upgrade that does not affect any remaining third-party cover you may hold.
