Dell OptiPlex 5040 Repair — your questions answered
How much does it cost to repair a Dell OptiPlex 5040 that won’t turn on?
A no-power OptiPlex 5040 is usually the internal PSU. Replacement with a tested 250 W or 315 W unit costs $145-$195 and is completed same or next business day with a 90-day warranty.
Can you upgrade my Dell OptiPlex 5040 to Windows 11?
Windows 11 is possible if the 6th-gen CPU passes the TPM 2.0 check via firmware update. We install a clean Windows 11 image after confirming compatibility or stay on Windows 10 if the CPU is unsupported.
