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.

  1. 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.

An overview of the machine

Click to enlarge

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.

Getting Started

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

Power button

The Power Button is located in the bottom right-hand corner of the bezel surrounding the screen. Note that it takes approximately two minutes for the machine to boot. However, the green power LED should come on immediately. 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. (With B4 units, the power button no longer gets caught under the bezel.)

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.)

Power off

Update

There is no longer a shut down mode, just power the device off by using the power button when you want to turn it off.

The Frame and the icons

Bring up the Frame onto the screen by pushing the Key frame.jpg key (an “empty rectangle” on it) on the upper right-hand corner of the keyboard or by moving the cursor to any corner of the screen (aka 'Hot Corners').

Here is how the frame is organized and a screen capture of the frame.

Top-left icons (places)

Top-left icons
  • Circle with 8 dots: This icon shows you the entire Neighborhood. Brings up all users available on the mesh network;
  • Circle with 3 dots: This icon takes you to your Friends/Groups view. Shows all users on mesh network that you have identified as friends;
  • Circle with 1 dot: This icon takes you to your Home screen;
  • Circle with rectangle: This icon takes you back to the Activity you were working on.


Top-right icons (status)

Update: On Build 303+ only the bulletin-board icon is in the upper-right of the frame.

Bottom-left icons (actions)

Bottom-left icons

Different builds have different collections of activities. You should see something along the lines of the following:

  • Globe: This icon starts the web browser;
  • Shooting Star: This icon starts the Etoys activity;
  • Speaking Bubble: This icon starts the chat activity;
  • Abstract A: This icon starts the text editor;
  • Penguin in front of the TV: This icon starts the RSS-feed reader;
  • 3×3 Matrix: This icon starts the Memosono game;
  • Eye: This icon starts the camera;
  • Drum: This icon start the Tam Tam activity.

Other activities include BlockParty, an ebook reader, a slideshow viewer...

The Keyboard

Keyboard
Touchpad

The center part of the touchpad can be used as a pointing device. The entire surface can be used with a stylus.

Demo instructions

Patience is very important: the user interface does not yet tell you that it is busy starting activities, and we have just begun performance work. You are using alpha test software.

Demo Suite:

  1. Web Browsing
  2. Etoys
  3. Memosono Game
  4. Tam Tam
  5. Dual resolution monitor
  6. eBook and Camera
  7. Chat

Home screen

Home view

After you turn on the laptop you will come directly to the Home screen.

To begin, bring up the Frame by pushing the “Frame” Key frame.jpg key on the upper-right corner of the keyboard.

The Network

As many demos use the network (browser, RSS feed, mesh demos), before you begin, the laptop should be associated with a network. The laptop should be able to access any wireless networks in the area.

Click on the network icon (five bars on the upper-right of the Frame). A list of available wireless networks will show up in a drop down menu.

If you cannot see any networks, it may be because the embedded control did not properly initialize the USB ports (the network controller is a USB device)—you will need to reboot.

Switching between activities

You can have multiple activities running at once—moving between them by returning to the Home view (key with one dot—Key zoom.jpg) and then clicking on an activity that you'd like to go to.

Exiting Activities

To exit an activity, click on the Frame Key frame.jpg key to bring up the Frame.

Put the cursor over the activity icon at the top center of the frame and click on the X with the circle around it.

exiting the browser

1. Web Browsing

Browsing

To launch the web browser, click the "globe" icon Activity3.png at the bottom-left-hand corner of the Frame; place the cursor over the icon and click the left button below the touch pad ONCE.

Type search terms into the Google search field or type URL in bar at the top of the screen.

Please note that currently, the web browser does not support Flash, Java or Chinese characters.

2. Etoys

Etoys

From the frame, click the shooting-star icon Activity1.png, 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.

From the Frame, click on the icon that looks like a 3×3 matrix—Activity7.png.

Play game by giving each player a turn to click on pairs of blocks to reveal images with corresponding sounds. The object of the game is to make as many matches as possible.

4. TamTam

From the Frame, click on the drum icon—Activity8.png.

Each picture on the right-hand side of the screen makes its own distinct sound. Click on the drum icons on the lower-right corner to set a beat for your composition. The far-right slider controls tempo of the drum.

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.

Key slider.jpg

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.

Using the camera

The camera can be used in ebook mode, but needs to be turned on in laptop mode: from the Frame, click on the eye icon—Activity6.png. Turn off the Frame and then put the laptop into ebook mode.

7. Chat

Prerequisite--sign onto Wireless network—preferably an open network that requires no authentication.

  • Go to network view. (Key zoom.jpg—Circle with 8 dots: This icon shows you the entire Neighborhood. Brings up all users available on the mesh network;)
  • Add other XO icons as friends by selecting them.
  • Open Chat application by clicking on balloon icon—Activity2.png.
  • Return to network view
  • You should see the XO characters as well as the chat activity
  • Click on the chat activity
  • Wait a minute
  • Start chatting.

8. Write

Other HowTo's

How to see what programs are running

Turn on the Frame and click the circle with one dot in it at the top left hand corner of the frame or push that same button on the top row of the keys on the keyboard.

Key zoom.jpg — Buttons from Left to Right: Neighborhood, Friends/Groups, Home, Back to Activity

Home.jpg

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

1. Keys that do not work

Key camera mic.jpg — Camera/microphone toggle key

Key grab.jpg — Grab keys (on either side of the space bar)

2. The laptop does not turn on

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.

Battery-1.jpg Battery-2.jpg

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.

3. The touch pad and keyboard are locked up

This most likely caused by static. Try the "four-finger salute": depress the four keys in the four corners of the keyboard (Fn, Esc, Frame, and Right Arrow). If this does not help, follow the instructions for restarting the laptop by removing the battery.

4. I can’t shut an activity down because the icon does not show up in the Frame

Try restarting Sugar by typing Ctrl-Alt-Erase. It should take about 30 seconds for Sugar to restart. If that fails, then try power-cycling the machine by pushing the power button. If all else fails, unplug the machine and remove the battery. Wait 30 seconds and then reinsert the battery, plug it back in, and power on.
