Repair FAQs
My ASUS mini PC won’t turn on — can you fix it?
Usually, yes. The most common cause is a failed power adapter or power circuit; we diagnose it and quote upfront, with no fix, no fee.
My ASUS mini PC overheats and shuts down — is that fixable?
Yes — compact chassis trap heat as dust builds up. We clean, re-paste and restore cooling so it runs stable again.
Will my data be safe during the repair?
Yes — we take care to preserve your data, and can image the drive first or recover data separately if a drive has failed.
How much does it cost?
You get a free Quick Quote and an upfront fixed price after diagnosis — and no fix, no fee.

ASUS Mini PC Repair — your questions answered
How much does it cost to repair an ASUS mini PC that won’t turn on?
A dead ASUS PN or ExpertCenter is most often the external power adapter or the DC-in jack on the board. We test the adapter first; if the board itself is at fault the repair usually lands between $220 and $380 depending on parts required. You only pay if we fix it.
Can you fix an ASUS ROG NUC that keeps shutting down from overheating?
Yes. The compact blower in ROG NUC units clogs quickly in Australian homes. We strip the chassis, clear the heatsink fins, replace the thermal paste and test under load; most units are back within two business days for $120-$180.
My ASUS mini PC won’t detect the SSD — is that a common fault?
NVMe drive failure is frequent on the PN series after three to four years. We clone your data where possible, fit a new 2280 drive and reinstall the operating system; pricing starts around $180 for a 512 GB replacement.
Do you repair ASUS mini PCs onsite or do I have to post it?
We offer onsite visits in capital cities, remote diagnostics Australia-wide, or you can send the unit to our workshop. The choice is yours and the 90-day warranty applies regardless of the method.
Will replacing the RAM fix random restarts on my ExpertCenter PN?
Sometimes. Faulty or mismatched SO-DIMMs cause POST failures and restarts. We test each stick individually; if memory is the culprit a matched 16 GB kit replacement is typically $140-$210 and resolves the issue.
