Removing the computer cover
Attention
Turn off the computer and wait 3 to 5 minutes to let the computer
cool down before removing the computer cover.
Note
It may be helpful to place the computer face-down on a soft flat surface for
this procedure. Lenovo recommends that you use a blanket, towel, or other
soft cloth to protect the computer screen from scratches or other damage.
