Dell Precision 3620 Repair — your questions answered
How much does it cost to repair a Dell Precision 3620 that won't turn on?
A no-power fault is usually the internal 365 W PSU or swollen capacitors on the 0F6T8G board. Parts and labour typically fall between $180 and $340 with a same or next-day turnaround and 90-day warranty.
Can you upgrade my Dell Precision 3620 to Windows 11?
Yes. After confirming the Xeon E3-12xx v5 meets the TPM 2.0 requirement via firmware, we fit a supported NVMe or SATA SSD, add at least 16 GB RAM and perform a clean Windows 11 install for $160-$280.
Is data recovery included if my hard drive has failed?
We clone any readable sectors to the new SSD at no extra charge. If the drive is clicking or has bad sectors we quote a separate recovery service starting from $250 before any work begins.
Do you still repair out-of-warranty Dell Precision 3620 workstations?
Absolutely. We stock OEM-spec PSUs, ECC memory and quality SSDs for this 2016–2017 tower and provide a 90-day warranty on every repair completed onsite, remotely or in our workshop.
How long will a Dell Precision 3620 last after an SSD and RAM upgrade?
Most units remain productive for another three to five years once the original spinning drive is replaced and the system is kept dust-free, making the upgrade far cheaper than buying a new workstation.
