🛠️ Step-by-Step Installation Instructions
Power Off & Static Discharge
Shut down Windows completely (not sleep or hibernate). Disconnect the AC adapter. Press and hold power button for 10 seconds to discharge residual capacitor power.
Remove Bottom Panel
Unscrew all bottom base cover screws using a Phillips #00 screwdriver. Use a plastic pry tool around the perimeter seams to unclip the casing without scratching the chassis.
Disconnect Battery Before Touching RAM
Carefully unplug the battery cable from the motherboard. This prevents short circuits while inserting metal contact pins.
Seat Memory at 30° Angle & Clip
Align the gold pin notch with the slot key. Insert the SO-DIMM module firmly at a 30-degree angle, then gently press down flat until the two side metal clips click into place.
First Boot Memory Training
Reconnect battery, clip cover back on, and plug in charger. The first boot may take 30–60 seconds while the motherboard trains the new memory timing.
