Lenovo ThinkCentre M900 Repair — your questions answered

How much does it cost to repair a Lenovo ThinkCentre M900 that won't turn on?

Most no-power faults on the M900 trace to the 280 W PSU or swollen capacitors. A replacement PSU is typically $180-$260 and capacitor work runs $220-$340, both completed with a 90-day warranty and no fix, no fee policy.

Can you upgrade my Lenovo ThinkCentre M900 to Windows 11?

Yes. After confirming the Intel 6th-gen CPU meets the TPM 2.0 requirement via firmware, we perform a clean Windows 11 install on a new SSD with updated drivers and a 90-day warranty on labour.

Is it worth replacing the hard drive in an older ThinkCentre M900?

Absolutely. Swapping the mechanical 2.5-inch drive for a 500 GB or 1 TB SATA SSD plus data cloning usually costs from $165 and transforms boot times and responsiveness without replacing the entire machine.

Do you come to my office or home for ThinkCentre repairs?

We offer onsite service across Australia for the M900. A technician can visit for diagnostics and many repairs on the same or next business day, charged from $110 for the visit plus any parts required.

What warranty do you provide on ThinkCentre M900 repairs?

All parts and labour carry a 90-day warranty. If the same fault reappears within that period we return at no extra charge under our no fix, no fee guarantee.
