SSD/Storage Upgrade Guide
Storage upgrades are essential for performance. The Lenovo ThinkCentre M920 supports M.2 NVMe + 2.5″ SATA SSD, giving you options for expansion. Modern NVMe SSDs offer dramatically faster boot times and file transfer speeds compared to older SATA drives.
Check which storage bays are currently in use by opening Device Manager (Windows) or System Report (macOS) to see what’s installed. An empty M.2 slot or 2.5-inch bay means you can add a second drive without removing existing storage.
Step-by-Step Installation
Before starting: Power off the computer completely and unplug the power cable. Ground yourself by touching a metal part of the chassis to prevent electrostatic discharge (ESD).
RAM Installation:
- Remove the side panel or access door (usually held by one or two screws or latches)
- Locate the empty RAM slots near the CPU
- Align the notch in the RAM module with the key in the slot
- Press the module straight down until the retaining clips snap into place on both ends
- Power on and verify the new RAM appears in System Information
SSD Installation (NVMe M.2):
- Locate the M.2 slot on the motherboard (usually marked on the motherboard diagram)
- Remove the small Phillips head screw and standoff if present
- Insert the SSD at a 30-degree angle, then press down and secure the screw
- Close the computer and power on
- Verify the drive appears in BIOS or Windows Disk Management
