cool down before replacing a memory module.

soft flat surface. Lenovo recommends that you use a blanket, towel,
or other soft cloth to protect the touch screen surface from scratches
or other damage.

shut down the operating system, turn off all attached devices, and the
computer.
2. Unplug all power cords from electrical outlets.
3. Disconnect all cables attached to the computer. This includes power
cords, input/output (I/O) cables, and any other cables that are
connected to the computer. Refer to “Locating connectors on the rear
of the computer”.
4. Remove the computer stand. Refer to “Removing the computer stand”.
5. Remove the computer cover. Refer to “Removing the computer cover”.
6. Remove the motherboard cover. Refer to “Removing the motherboard
