Explain Hot Spots, Cell Extenders

A hotspot is a location where you may obtain Internet access using WiFi. A smartphone can act as a hotspot using your phone service. You may obtain a hotspot device from a cellphone provider that is exclusively used to provide access to the internet using WiFi. Version’s is called a JetPack. Local businesses such as Panera Bread, MacDonalds, Walmart, etc provide hot spots for you to access the internet. These are public and caution should be used as others could be sharing the access with you.

A cell phone extender is a device that takes a weak existing outside cell signal, amplifies it, and then broadcasts that boosted signal to an area inside of your home.

Power Options

In the bottom right of your screen, right-click the battery.

Choose Power Options

Note: if you are on a desktop, right-click the start button and click Power Options. Then click Additional power settings to see the following window.

On the left side, select Choose what closing the lid does

I have mine set for Do Nothing. That gives me the option to close the lid and use an external monitor, keyboard, and mouse without the laptop screen visible. It is like having a desktop that I can travel with. I also have the power button set to take me through a normal shutdown when I press it. I do not have a sleep button so that one means nothing to my laptop.

USB Explained
USB, short for Universal Serial Bus, is a common type of computer port that makes it easy to charge a device or transfer data between two devices.

USB speed and colors

USB 1.1 1.5 mb/s white

USB 2.0 60 mb/s black

USB 3.0 625 mb/s blue

USB 3.1 1,210 mb/s red*

What is the difference between USB 3 and USB C?

USB 3.1’s is double the bandwidth of USB 3. USB Type-C isn’t the same thing as USB 3.1, though. USB Type-C is just a connector shape, and the underlying technology could just be USB 2 or USB 3.0.

Note: many of the new computers are coming in with USB 3 installed but black connectors. Check the specifications for the computer to be sure of what is there.

*Orange: the connector does not power off during sleep or standby mode.
