Dealing with summer heat is extra awful when trying to get a good night's sleep. Rather than suffering through the warmer months, use a few appliances to keep your bedroom at a cool, comfortable temperature. This includes utilizing a dehumidifier, which will not alternate room temperature but will remove humidity.
A dongle is a small piece of hardware that connects to another device to provide it with additional functionality.
If the hardware switch is permanently off the only solution is to fix the switch. This will obviously require a bit of surgery on the laptop. You may not be so adventurous (and there is some risk in this), which leaves two choices: 1. find a repair shop to fix the switch. 2. use a USB wifi dongle. Apr 20, 2013, 5:41 PM.
