How to check whether a Notebook PC is equipped with a wireless
card?
A. Enter Control Panel -> Device Manager. You will see whether
the Notebook PC has a WLAN card under the "Network Adapter"

Why is the cooling fan always ON and the temperature high?

to decrease system load.

software to detect them.
4. If none of the above help, try restoring your system using the
recovery partition or DVD.
