HP EliteDesk 800 G1 Repair — your questions answered
How much does it cost to repair an HP EliteDesk 800 G1 that won't turn on?
A no-power fault is most often the 320 W PSU. Replacement with a tested OEM-spec unit is typically $180-$260 and usually completed same or next business day. We test the motherboard rails before quoting so you only pay if the repair succeeds.
Can you upgrade my HP EliteDesk 800 G1 to Windows 11?
Yes. We perform a clean Windows 11 install after confirming the Intel 4th-gen CPU meets the TPM 2.0 requirement via firmware update. Cost for the install, activation and driver set is $130-$190 and the machine remains eligible for future updates.
Is it worth replacing the hard drive in an HP EliteDesk 800 G1?
Replacing the ageing mechanical drive with a 500 GB or 1 TB SATA SSD restores responsiveness and eliminates clicking. We clone your data sector-by-sector so nothing is lost. The job costs $220-$310 including recovery and usually takes one day.
My HP EliteDesk 800 G1 shuts down after 20 minutes — what is wrong?
Dust-clogged heatsinks and dried thermal paste are the usual cause. We remove the cooler, clean the aluminium fins, replace the paste and test under sustained load. The service is $89 and normally completed the same day.
Do you repair HP EliteDesk 800 G1 units that are out of warranty?
We accept all out-of-warranty and ex-fleet 800 G1 units. Parts are OEM-spec or quality refurbished stock with a 90-day warranty on both parts and labour. Onsite, remote and workshop options are available Australia-wide.
