HP ProDesk 600 G1 Repair — your questions answered
How much does it cost to replace the power supply in an HP ProDesk 600 G1?
A replacement 180 W proprietary PSU costs between $145 and $195 including labour when done in our workshop. We test the new unit under load before returning the machine, and the job is usually completed the same day.
Can you upgrade an HP ProDesk 600 G1 to Windows 11?
Yes. We fit a compatible TPM 2.0 module if missing, install a supported CPU if required, and perform a clean Windows 11 install. Most 600 G1 units meet the requirements after these changes; we provide a fixed quote before starting.
My HP ProDesk 600 G1 has an amber blinking light and won’t turn on. What’s wrong?
An amber blinking LED on the 600 G1 usually points to a failed power supply or swollen capacitors on the motherboard. We run a full diagnostic first; if it’s the PSU the repair is typically $145-$195, while capacitor work ranges from $220-$290.
Is it worth replacing the hard drive in an old HP ProDesk 600 G1?
Replacing the mechanical drive with a 500 GB or 1 TB SSD dramatically improves speed and reliability. The upgrade including cloning your data starts from $165 and usually takes only a few hours, extending the useful life of the machine by years.
Do you offer onsite repair for the HP ProDesk 600 G1 in regional areas?
Yes, our technicians travel to homes and offices across Australia. Onsite service is available for power supply, SSD and RAM work; motherboard-level repairs are completed in the workshop with a 90-day warranty on all parts and labour.
