Thermal

The vent hole of the POC-W211 rear cover functions as a cooling air flow inlet and
outlet. These air inlets and outlets transfer heat from inside the computer to the
cooler air outside. Do not block these holes/vents with any soft material.
When using your POC-W211 system, it is normal for the rear metal heatsink to get
warm. The rear metal heatsink of the POC-W211 functions as a cooling surface that
transfers heat from inside the computer to the cooler air outside. Do not block this
heatsink with any soft material.
Warning! Do not place your POC-W211 system on a pillow or other soft material
when it is on, as the material may block the airflow and cause the com-
puter to overheat.
5.4

Disconnect the Power

The only way to disconnect power completely is to unplug the adapter power cord.
Make sure at least one end of the power cord is within easy reach so that you can
unplug the computer when you need to.
Warning! Your AC cord came equipped with a three-wire grounding plug (a plug
that has a third grounding pin). This plug will fit only a grounded AC out-
let. If you are unable to insert the plug into an outlet because the outlet is
not grounded, contact a licensed electrician to replace the outlet with a
properly grounded outlet. Do not defeat the purpose of the grounding
plug.
