Disconnect the AC power cord and remove the battery.
Prior to handling the memory module(s), always touch an unpainted and grounded metal object or use a grounded antistatic wrist strap to prevent electrostatic discharge (ESD).
If necessary, remove pre-existing memory by gently pulling the lock/ejector tabs (located on both sides of the memory socket) away from the memory module. The memory will unlock and pop-up 30 degrees for removal.
Note: Never apply pressure or handle the memory module on or around the Integrated Circuits (IC)! Always handle the memory at the upper-most corners of the Printed Circuit Board (PCB).
Align the memory module key along with the memory socket key and insert the memory at a 30 degree angle.
Rotate the memory downward until the lock/ejector tabs engage and click into place.
Replace the battery and plug in the AC power cord.
