Demo notes/542
This page, a work in progress, will describe the demonstration instructions for Build 542, the Trial 2 Build for the B4 laptops. It is modeled after the B1 Demo Notes page (See Hardware release notes, Software release notes, and Library release notes for additional information).
Important Notes
Please note that the B4 laptops are Beta units and that the software is Alpha; we expect that Trial-3 software will be our first Beta software release). There are bugs (please refer to the bug tracking system at http://dev.laptop.org); not all components are yet operational.
- There are still some outstanding issues with power management; battery life will not be as good as it will get.
More detail regarding the status of various software components is available on the OLPC Trial-2 Software Release Notes page in this wiki.
Getting Started
An overview of the laptop
This figure will be replaced by a B4 unit. Perhaps the most significant change is the position of the microphone, which has moved over to the left side of the bezel and the addition of LED indicator lights above both the camera and microphone.
The keyboard
The center part of the touchpad can be used as a pointing device. The entire surface can be used with a stylus.
Opening the laptop
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 up on the display.

Note that the laptops in these figures are B2 units (B4 units have a dual-tone XO on the back of the machines).
Power on and power off
The Power Button is located in the bottom right-hand corner of the bezel surrounding the screen. The green power LED should come on immediately, but it takes approximately two minutes for the machine to boot. If, for some reason, you do not see text appear on the screen within 15 seconds, or if the machine does not power on at all, please see the #Bugs and or Known Issues Section at the end of this document.
Once the laptop is running, the Power Button is used for suspend. You must hold down the button for 10 seconds to shutdown the laptop. (You can also shutdown the laptop from the hover menu on the XO figure on the home view.)
Using the laptop
Home View
Features of the Home View include the XO icon; the network-status indicator; the battery-status indicator; and the Frame;
You can return to the Home View by hitting the Home Key (circle with one dot) or by clicking on the Home Icon on the Frame (as per below).
XO icon
Each laptop is assigned a color dyad that is used as an identifier throughout the interface.
There is a menu that appears when you place the cursor over the XO icon in the center of the screen. As of Build 542, this menu is only used for shutdown. It may be used for setting user preferences, such as colors, in the future.
Activity circle
The circle around the XO icon is used to display any activities that are currently running on the laptop. (In later builds, e.g., 547, the size of the sector is proportional to how much memory the activity is consuming. If the circle fills up, you will run out of memory.) The #Journal is always displayed at the bottom of the circle. You can resume an activity by clicking on its iconic representation in the circle.
Network status
The status of the wireless network is indicated by either a circle (mesh) or triangle (infrastructure) on the Home View. Details regarding connectivity are described below.
Battery status
The battery status is indicated by a battery icon. The icon fills with color from the left to indicate the current charge. Putting the cursor over the battery icon brings up more detail. Please note that the battery LED is illuminated when the battery is charging; it varies from yellow to green. Red is used to indicate that the battery is running low.
Frame
The Frame appears by default on the Home View. (It does not appear by default in any other view.) You can toggle the Frame with the Frame Key on the most upper-right corner of the keyboard 
or by moving the cursor to any corner of the screen (aka 'Hot Corners').
Upper-left icons (places)
- Circle with eight dots: This icon takes you to the #Neighborhood View, where you see network resources and the other users on the mesh network;
- Circle with three dots: This icon takes you to the #Group View, where you see those users have identified as friends;
- Circle with one dot: This icon takes you to the #Home View;
- Circle with rectangle: This icon returns you to the #Activity View, where you resume work on the current activity.
Bottom icons (actions)
Different builds have different collections of activities. In Build 542, you should see:
- #BlockParty: a falling-block game;
- #Draw: a drawing activity;
- #Calculate:a calculator;
- #Write:a word processor;
- #Chat:a text chat program;
- #Etoys:a programing environment;
- #Browse:a web browser;
- #News':an RSS news feed;
- #Connect4:a Connect4 game;
- #Watch and Listen:a multimedia player;
- #TamTam:a music activity;
- #TurtleArt:a programing environment;
- #Record:a video capture activity.
Right-side icons (buddies)
The XO icons of the other people with whom you are collaborating show up on the right-hand side of the Frame.
Left-side icons (clipboard)
The left side of the Frame is for the clipboard.
Neighborhood View
From the Neighborhood View (sometimes referred to as the Mesh View), you can see who is present on the network, what activities and objects are being shared, and what networks are available. You can access this view by hitting the Neighborhood Key (eight dots) or by clicking on the Neighborhood Icon (as per above on the Frame).
Your icon will appear in the center of the screen. Putting your cursor over an icon invokes a hover that provides some additional details or actions to take.
Getting connected
The circle and triangles represent the mesh and infrastructure access points. (The access points are color-coded by a random hash generated from the ESSID.) By default, Network Manager first tries to connect to a School server; then an access point; if that fails, it resorts to a mesh point on Channel 1. This searching process can take up to five minutes, since there are many channels to check and timeouts associated with each one. You can override Network Manager by clicking on a triangle (access point). The interior of the triangle will blink while the connection is being established. The exterior of the triangle will blink when the connection has been established. (If you are connecting to a WEP access point, you will be prompted for a hexadecimal key. We currently do not support WAP access point.)
More details re the connection:
- if you connect to an access point, your laptop will become a mesh portal point -- other laptops in the vicinity will be able to connect to the Internet through your laptop;
- similarly, if there is another laptop connected to an access point, you should be able to connect to it -- and the Internet -- through the mesh;
- if there are no access points available, your laptop will default to a mesh point on Channel 1, enabling it to connect to other laptops;
- please be patient: it takes Network Manager up to five minutes to walk through all of the options.
Joining an activity
Clicking on an activity icon from the Mesh View will launch that activity on your laptop as a collaboration. The details of the collaboration varies from activity to activity.
Adding a buddy
Hovering over an XO icon reveals the name of the person associated with that icon and a menu that can be used to add them to your Groups View.
Group View
There is not much you can do from the Group View (sometimes referred to as the Friend View) except to see which of your friends is present on the network. You can access this view by hitting the Group Key (three dots) or by clicking on the Group Icon (as per above on the Frame).
Activity View
There Activity View is where you run applications. You can resume the current activity by hitting the Actitvity Key (rectangle) or by clicking on the Activity Icon (as per above on the Frame).
Activities
Switching between activities
You can have multiple activities running at once—moving between them by returning to the Home view (key with one dot—) and then clicking on an activity that you'd like to return to. (There will be hot-key tabbing between activities in future builds.)
Exiting Activities
Every activity has an Activity tab that includes a Stop Icon. Clicking on this icon exits the activity. Alt-C works -- in most cases -- as a shortcut for exiting activities. (The Keep Icon will be used for version control in the Journal.)
Journal
The Journal is accessed from the Journal Icon at the bottom of the Activity Circle on the Home View. The Journal automatically logs your activities on the laptop. 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 one can resume an activity or copy its contents onto the clipboard.
Web Browsing
To launch the web browser, click the "Globe" Icon 
on the Frame. The browser has two tabs: the standard Activity Tab and a Browser Tab. The latter has a address field, forward and backward history buttons, and a reload button.
2. Etoys
From the frame, click the shooting-star icon 
, ONCE. The Etoys activity will load and show a launch screen:
- yellow "demo": shows a "welcome demo" that will run in a loop. You can exit the demo by clicking "PREV" in the orange "Navigator" bar at the bottom left.
- orange "tutorial game": a nice tutorial to learn about Etoys "handles".
- violet "new project": start creating your own projects. Journal integration is still missing, but you can save your work to the MyEtoys folder by pressing "PUBLISH" in the orange navbar. There is extensive documentation on Etoys in the wiki (start here) and at squeakland.org.
- green "project gallery": Load example science and fun projects
- blue "load project": find a project on disk.
3. Memosono game
This is a memory game for two players. Winner matches the most images and completes his/her ice-cream cone on the right-hand side.

Use the keyboard to play sounds at different pitches.
5. Dual-resolution display
These are instructions for demonstrating both the color and the black-and-white modes of the display from any activity. In black-and-white mode, with the backlight off, the screen is high resolution and viewable in sunlight; it is the most energy-efficient setting.
On the top row of the keyboard is a long button with different-sized solid circles.
The two larger circles control the B&W and color modes on the display.
- Pushing the largest circle (far right) puts the display into B&W mode.
- Pushing the second largest (second from the right) circle puts the display into color mode.
The two smaller circles on the left side of the button control the backlight.
- To turn off the backlight, press the smallest dot (on the far left) 12 to 15 times.
- To turn on the backlight, press the second dot from the left between 12 and 15 times.
6. Handheld mode (or eBook mode) and camera mode
When in this mode, keyboard and touchpad are covered, so only game controller buttons (which can be used for scrolling), camera, and microphone work.
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!

— Buttons from Left to Right: Neighborhood, Friends/Groups, Home, Back to Activity
Home screen will come up, but this time, icons that represent the programs running will appear in a circle around the XO logo. This is called the activity ring. When the ring is full you will not be able to start any more activities.
Click the icon to access that activity.
Bugs and or Known Issues
Keys that do not work
— Journal search key
— Bulletin-board key
— Grab keys (on either side of the space bar)
The laptop does not turn on
The fix is probably to reset the embedded controller (EC):
- You must unplug the laptop and remove the battery;
- Turn the XO over and move the button on the right side to the right; this will unlock the battery;
; - Move button on the left side to the left while lifting up the battery.
- Remove the battery and wait at least 30 seconds.
- Replace the battery and lock the battery in place.
- Plug the laptop back in.
Note that if you have completely discharged your battery, you will have to run the laptop without the battery—a bug in the battery-charge circuit prevents the charging of a completely dead battery.
