3

3. Gently slide a plastic pick around the chassis boundary to disengage clips.

4

4. Remove bottom plate and disconnect the battery connector.

5

5. RAM slots are under the central metal cover; lift shield, push side tabs to pop RAM up at 45 degrees.

6

6. SSD slots are on the left and right; unscrew the metal heatsink shields to access M.2 2280 slots.

7

7. Insert replacement components, re-affix shields, re-attach battery, and secure screws.

Looking for Storage & M.2 SSD Upgrades?

Inspect underside M.2 clearance limits (≤2.38mm), secondary slot form factors, and avoid double-sided NAND clearance traps.
