By the Community, For the Community: Introducing the XO

A community of people built the XO laptop and everything within it, with YOU in mind.

The XO laptop is designed to help you, your family, and your community to learn and grow. It is meant to be explored, and enjoyed. It has tools and games to help you expand your knowledge and to have fun. Another purpose of the XO laptop is to help you make new friends, in your own area or across the world. There are groups and communities that you can join, and you can also start your own.

If you have spent time on the Internet, there's a good chance you have heard of Wikipedia, which is a free online library created by people around the world. Wikipedia is one of the most recognized names in the world, thanks to the contributors, and there are many other projects built around the same principles. This includes all of the interesting new activities that have been developed as part of the laptop project, such as Colingo, and many others. We'll be adding more all the time, and so can you!

The important thing to remember is that there is only one serious mistake you can make on the Wikipedia website, or on the XO laptop:

The Mistake: thinking that your contribution would not be helpful.

The reason Wikipedia has been so successful is because it is very helpful; and the reason it is helpful is because of all the people who have taken the time to add or improve something. (And they often end up having fun in the process!) With the community approach, there is something for everyone.

Like any community effort, the XO laptop has great things about it, and it also has room for improvement. Ideas and feedback are one of the greatest gifts that you can give; you don't need to be an expert, you just need to be willing to share your thoughts. And the community would be glad to hear them.

We hope that the XO laptop is helpful, that you enjoy and learn from it. And we hope that someday you will join us in making it better.

All are welcome.

About computers

Your XO is a computer.

What is a computer? A computer is a tool, a classroom, a toy, offering a way to communicate with others. Use your computer for learning, for fun with pictures and games, or for communication. A computer can be whatever you want it to be. Many people use computers to write, to perform mathematics, to create art, to play games, to record sound and images, to communicate with others, to read, and to learn.

What can the XO do? Your XO can store written stories, videos, pictures, an entire library. It can play music, and you can make music with it. It contains Activities that you can use to learn math, play games, create pictures, and communicate with others. You interact with the XO using the touchpad, or graphics tablet, keyboard, microphone, or camera.

How does it do it? With your XO, you can figure out how it works for yourself by reading about computers and learning the basics, then learn about hardware and software.

Opening the XO

How to open the XO.

Physically you can open, flip, and close the XO to position it in different ways.

To open it, position the handle away from you and lift both antennae up and toward you until the laptop clicks open. Lift the screen up from the keyboard; you may have to hold the keyboard down as you lift the display.

To open:

For handheld mode, lift the "bunny ears."
Listen for the laptop clicking open.

How to switch screen positions.

To flip:

Bring the display up to a 90-degree angle and put the antennae down.
Rotate the display 180 degrees until it is facing backwards.
Lay the display down onto the keyboard.
Enjoy the XO in this mode!

Starting the XO

When you press the Power button, the XO starts up after about two minutes, and then asks your name. Enter your name, and then look at your XO camera (small round dot on the right next to the screen) while it takes your picture.

Connecting your XO to the network

Thanks to network connections, you and your XO are going places while staying close to home.

Your XO connects to and networks with other computers. The XO can take up to five minutes to find network connections. While it's searching, the inside of a colored circle or triangle icon blinks. You might need to ask your teacher what to enter if your XO asks you to enter an access key.

While your XO remains connected, the outline of the shape blinks.

Mesh Icon Mesh Icon Network or Access Point Icon

More information about your XO's connection:

If you connect to an wireless network, your laptop becomes a network point; other XO laptops within about 100 meters can connect to the Internet through your XO laptop.
Similarly, if there is another XO connected to the Internet nearby, you can connect to that XO laptop—and the Internet—through the other XO.
If there are no Internet network points available after five minutes of searching, your XO laptop defaults to Channel 1, which enables your XO laptop to connect to other XO laptops.
Please be patient; it can take your XO up to five minutes to find a good connection.

Cleaning and caring for your XO

While your XO is tough, you should try to keep your XO dry and clean. If it gets dirty, wipe it with a damp cloth and dry it. It can survive an occasional accidental soaking in a rain storm, but don't dip it all the way into water.

The XO laptop has no hard drive to crash and only two internal cables, so it is less likely to fail than other laptops. For added robustness, the XO's plastic walls are thicker than the standards for other laptops. Its green mesh network antennas, or "bunny ears," have improved wireless capabilities over the typical laptop. Plus, they double as external covers for the USB ports, which are protected internally as well. Internal bumpers protect the screen display by offering cushioning.

Personalizing your XO

When you start your XO, you'll see a small O on top of an X. This symbol represents you when you use your XO. Click this person symbol to choose colors that represent you best.

Avoiding loss of your XO

Although your XO handle is sturdy enough for you to carry your XO by it, you may want to put your XO in a bag with a shoulder strap for easier carrying. When you first start the XO, if a school server is available, it registers with your school's server to give you additional storage for pictures or stories that you make. Also, to ensure that no one other than you can use your XO, the XO sends a security code that lets officials track down your XO if needed.

Copying the XO contents (backing up)

Your XO will automatically copy items from the Journal to your school server, which provides a way to "back up" your information. This "back up" process means that if you ever lost a song or image or story that you wrote, you can get it back (recover it) from your school server and put it on your XO laptop. If you think you have lost something, ask your teacher to run the backup-restore command.

If you needed to replace your XO laptop with a new one for some reason, then your teacher can follow these instructions for copying all of your songs or stories or other files.

(optional) Insert teacher USB key into laptop, which identifies the administrator for the school server. If a teacher USB key is present, you do not have to enter a password for the restore command.
Press Ctrl Alt F2, also called the world view key.
Log in using the root username and password.
At the command line, type

identity-restore "nickname"

If teacher USB key isn't present, you must enter the password for the xoreg user on the school server.
Return to the Sugar console by pressing Ctrl Alt F4, also called the application view key.

Also, in the Journal, you can click the Backup tab and if your laptop is registered to a school server, the XO laptop copies your files to the school server.

Keeping information in the Journal

Use the Journal to view a collection of all your Activities on the laptop. Click the Journal icon at the bottom of the Activity Circle on the Home View. From the Journal, you can search by keyword and sort by activity or date. Clicking on an entry brings up a detail page from which you can resume an activity (by clicking on the Activity Icon or Key ) or copy its contents onto the clipboard (by pressing on the Copy Icon ).

The Journal also supports external media. When you plug a USB key into the XO, the contents from the USB key are entered into the datastore of the XO laptop to access using the Journal. Click on the USB icon to access the content. You can also drag and drop Journal entries on to or off of a USB key.

Charging the XO battery

Your XO needs power to run. Power is electricity, and there are two ways for your XO to get it: from its battery or from a power cord. Your XO laptop battery should run for about three hours of use on a full change.

Using Battery Power

Your battery is like a suitcase for electricity. When you first get your XO, the suitcase is empty, so you need to fill it up. That means you have to store some electricity in your battery before you can travel away from a cord.

The battery icon does not indicate the number of hours or minutes remaining for the XO to run but displays a percentage of the battery life remaining.

The battery is on the back of your XO.

Here's how to charge up the battery:

Plug the power cord into your XO.
Plug the other end of the power cord into the nearest power source, such as the one connected to the school's generator or a car battery when used with the proper adapter.

Plugging in your XO

You can use your XO when you're charging the battery or when you have a good source for power. For power sources, you can use the generator supplied by the OLPC Project to your school or another source of electricity.

When to charge the battery

The battery icon fills with color, showing you the current charge, or amount of power in the suitcase. Move the cursor over the battery icon to see more information. Also, when the battery is charging, the battery light displays color from yellow to green. A red light tells you that the battery is running low and you should charge it soon.

Removing the battery

[[Image:Removing-the-battery.gif|thumb|100px|right|Removing and replacing the battery. You shouldn't need to remove the battery, unless it is faulty.

To remove the battery:

Switch off the XO.
Close the lid, and turn the XO over, so that the XO logo is on the underside.
Slide the catch on the right to the right. It will stay there.
Slide the catch on the left to the left. You will have to hold it in position, as it is sprung.
Lift the battery out from the central indentation between the two catches.

To replacing the battery:

Line up the four notches on the battery with the long edge furthest from the catches.
Drop the battery into place, then slide the left catch to the left, and press the battery gently into place.
Slide the right catch to the right to lock the battery in place.

Being safe with the XO

Your XO laptop is checked for safety against the European Union's RoHS Directive which ensures that it contains no hazardous or unsafe materials. Its NiMH batteries contain no toxic heavy metals, plus it features enhanced battery management for an extended recharge-cycle lifetime. The XO also uses alternate power-charging sources, such as a car battery, with a modified adapter. Ask an adult for help with chargers other than the provided AC adapter.

You might also be concerned about protecting your XO laptop from a computer virus. The unique security system isolates each Activity so that a virus cannot easily infect the XO laptop. Currently you do not need to install separate anti-virus software or firewall software.

Please realize that the XO laptop is designed for easy-to-use wireless connection to the Internet and other networks, but you should be careful and ask your teacher or parent for help and protection. They need to know that "Internet access must be purchased separately through an independent Internet Service Provider (ISP). In selecting an ISP, you should remember that, in addition to the many wonderful sites and educational resources on the Internet and World Wide Web, there are places where you wouldn’t want your child to go and people you wouldn’t want your child to meet. That’s why many ISPs offer “filters” that assist you in monitoring and/or controlling your child’s Internet access. So your child can have a safe and healthful experience, OLPC FOUNDATION RECOMMENDS THAT YOU USE AN APPROPRIATE INTERNET FILTER, REMAIN INVOLVED IN YOUR CHILD’S USE OF THE INTERNET AND, OF COURSE, STAY ACTIVELY ENGAGED IN YOUR CHILD’S EDUCATION."

By our estimates, your XO should last at least five years. To help ensure such durability, take care of it well.

Navigating the XO screen

The Frame

The entire XO screen has a dark gray border called the frame. The left, top, and right sides of the frame represents nouns: persons, places, and things. The bottom of the frame represents those elements that require action: activities, invitations, and notifications.

Bring the frame onto the screen by pushing the key (an “empty rectangle” on it) on the upper right-hand corner of the keyboard or by moving the pointer to any corner of the screen

Views (places) A view is another word for a place. You can open different views (places) by clicking on the pictures in the top left corner of the frame. The different views are neighborhood view, friend view, and home view.

Home View

If you leave the Home View to engage in an Activity, you can return to the Home View at any time by pressing the Home Key (circle with one dot) on the keyboard or by clicking on the Home Icon (image), on the frame.

Activity Circle

The circle around the XO icon shows Activities that you are currently using on the XO. The Journal icon is always at the bottom of the circle. You can resume an Activity by clicking on its icon in the circle. If you leave your Activity without closing it, you can resume your current Activity by pressing the Actitvity Key (circle with rectangle) on the keyboard. You can keep opening new Activities until the ring is full, but when the Activity Circle is full you cannot start any more Activities until you close some.

Right side of the frame shows your XO buddies (image)

The menu on the right-hand side of the frame contains the XO icons of the people with whom you are collaborating on XO online projects.

Left side of the frame shows the clipboard

The menu on the left side of the frame contains the icons for the clipboard. You can drag and drop most Activities on and off of the clipboard.

Neighborhood View

From the Neighborhood View (also called the Mesh View), you can see

who is currently on the network
which activities and objects are being shared
which networks are available

You can access the Neighborhood View by pressing the Neighborhood Key on the keyboard (circle with eight dots -- ) or by pressing the Neighborhood Icon on the frame.

Your XO icon appears in the center of the screen in the Neighborhood View. Moving your cursor over another XO icon brings up a menu that provides additional details (user's name) and actions you can take (add to list of Friends).

Friends View

From the Friends View, you can see which friends are on the network. You can access this view by pressing the Group Key (circle with three dots) on the keyboard or by pressing on the Group Icon on the frame.

Adding a buddy

Hovering over an XO icon creates a pop-up window with the name of the person associated with that icon and a menu that can be used to add this person to your Friend View as a friend. Move the cursor to and select "Make a Friend" to add this person.

Understanding XO Hardware

The XO laptop contains 256Mb of RAM and has 1Gb of flash disk space. Additionally, three USB sockets are available for external or portable storage devices, and with the wireless network, you can store additional files to your school's server or to other network storage locations. There is also flash storage expansion capability with an SD Card slot.

The XO laptop has a built-in microphone and the built-in video and still picture camera takes pictures of 640 x 480 resolution at 30 Frames Per Second (FPS).

The wireless networking capability uses an integrated 802.11b/g (2.4GHz) interface and it supports a unique 802.11s (Mesh) networking protocol in addition.

Understanding XO Activities

Activities are fun things to do and share on the XO. Start an Activity by clicking on the picture for it in the bottom part of the frame or click on Activity in the Activity Circle.

Exit an activity

Every activity has an Activity tab that includes a Stop Icon. Click this icon to exit the Activity. Press Alt C to exit an Activity quickly. In the Journal, the Keep Icon keeps previous versions of the Activity.

You can rename a saved version of the Activity by typing into the text field on the Activity Tab.

Sometimes you can share the Activity with another user on the XO network by selecting "My Neighborhood" within the activity.

Joining an Activity

From the Neighborhood View, moving the cursor over an Activity icon and pressing the Enter key launches that Activity on your laptop as a collaboration. Details of the collaboration vary from one Activity to another.

Getting support for your XO

An entire community built this XO and everything on it, and we want to help you with it. If you have any questions about the XO, ask your teacher for help, or search on the Internet. The wiki.laptop.org website contains helpful information for using and fixing your XO.
