Refer to -[http://wiki.laptop.org/go/Developer\_key](http://wiki.laptop.org/go/Developer_key) -for more information about developer's keys. - -1. With the XO off, hold down the "check mark" game button (above the - power button) while pushing the power button. After start up, the - screen displays "Release the game keys to continue" and shows a text - diagram of which key is pressed. -2. Release the "check mark" game button. -3.

Press the the escape key (circle with an x) again to exit the - keyboard test. -8. At the ok prompt, type reboot to restart. - -Repairing damage to the keyboard -================================ - -If your keyboard becomes damaged, normally it has to be replaced. -Replacements are available through the repair centers. Information on -spare parts and repair centers can be found at -[http://wiki.laptop.org/go/Repair\_center\_locations](http://wiki.laptop.org/go/Repair_center_locations). - -Troubleshooting the internal XO hardware -======================================== - -The XO can give you information about possible repairs that are needed. - -Start by pressing the power button for a second, and then answer the -following questions. Does the Power LED half-circle light up? - -When the power button is pressed once, and the power LED doesn't turn -on, first try resetting it. - -To reset the XO, remove all power sources from the laptop: - -1. Take the battery out and remove the power adapter. -2. Wait two minutes. This allows embedded hardware to lose all power - and reset itself. -3. Replace at least one source of power, either the battery or power - adapter, and watch the power/battery LED while you do so. - -The battery LED should flash orange momentarily (about a quarter of a -second) when power is first reapplied. If you do not see this flash, you -either have a motherboard hardware problem or faulty EC firmware -installed. Contact a repair center for assistance. - -If the power LED doesn't turn on or flash, but the laptop proceeds to -illuminate the backlight and even start, the problem may be either the -LEDs themselves or the power LED driver. The LEDs are in series, so if -one fails they may both fail to light. - -On rare occasions, the power button becomes stuck mechanically. In this -case, the laptop does not detect the depression of the power button, and -does not turn on. Ensure that the power button is moving freely by -pressing it a few times. - -If the battery LED flashed on restoration of power and the power button -isn't stuck, and no other signs of life are detected, then you can't -determine the reason for failure. Contact a repair center for -assistance. Does the display light up? - -After starting the XO and viewing the power LED, the next visible -feedback from the XO is that the display lights up. The LCD display -should be initialized with white, then begin to show text or graphics. -The backlight for the screen should be turned on, even if the backlight -was previously turned off. - -If this does not happen then the boot sequence may not be operating -correctly. Next, look at the Microphone activity LED to see if it is -lit. If the power LED and the microphone LED are both lit then a serious -boot error has occurred and you should contact a repair center for -assistance. Can you hear the startup sound when the XO starts? - -If the startup sound does not play, this usually indicates a problem -that a repair center needs to fix. Yes, the startup sound plays - -If the display doesn't initialize, but the boot sound plays, then this -is probably a problem with the display. No, the XO boots normally, but -no boot sound plays - -If no boot sound is played, but the machine boots normally and has -audio, it is possible that the default boot volume to has been changed -to 0. While the boot sound is playing, you can adjust the volume using -the volume adjust keys. This modified volume setting is saved and used -for future boots. Try increasing the volume right after starting the -laptop a few times, and see if the boot sound returns. - -If no boot sound is played, and the machine boots normally but has no -audio see -[http://wiki.laptop.org/go/XO\_Troubleshooting\_AV](http://wiki.laptop.org/go/XO_Troubleshooting_AV). -Does the display remains blank after starting up? - -Sometimes the display is active (including backlight), but no text or -graphics appear. This problem can be caused by removing the power to an -XO while it is upgrading the firmware. You should contact a repair -center for assistance. Does the display say "Connect power to proceed"? -Sometimes a firmware update requires two sources of power, both a -battery and a power adapter. If this is the problem, provide both -sources of power and reboot. The XO should proceed with a firmware -update and boot normally. Is the display is showing an XO icon only? - -This means that the XO has started the startup process. - -You can see much more information about your Open Firmware by holding -the "check mark" game button (above the power button) after powering on. -That makes Open Firmware display more detailed messages about what it is -doing during the secure boot process (including early boot messages from -the Linux kernel). The messages are in English only. Is it showing an XO -icon with a serial number and three icons below it? - -If the laptop powers up, but stops when displaying the XO icon in the -middle of the screen, followed by a serial number (e.g. CSN74902B22) and -three icons (SD disk, USB disk, Network signal strength), it is looking -for its activation lease. This should eventually print "Activation lease -not found" at the top of the screen and power-off soon thereafter. - -The solution is to re-activate the laptop. Obtain a copy of the lease -(or a new lease) from your country activation manager, place it (named -"lease.sig") in the top-level directory of a USB key and boot the -laptop. See the "what to do with activation keys" section within: -[http://wiki.laptop.org/go/Activation\_and\_Developer\_Keys](http://wiki.laptop.org/go/Activation_and_Developer_Keys). -Is it showing an XO icon with a "sad face" above it? - -This means that Open Firmware couldn't find a signed operating system on -the internal flash memory. Firmware bootup also looks on USB memory -sticks and SD cards for signed operating system software. - -Try upgrading or re-installing the software: -[http://wiki.laptop.org/go/Secure\_Upgrade](http://wiki.laptop.org/go/Secure_Upgrade). -XO icon with a single dot below it? - -If the XO powers up, but stops when just displaying the XO icon in the -middle, with a single dot below it, it means that something was wrong -when the Linux operating system started. When this happens, try -upgrading or reinstalling the XO. If this has happened to the same XO -more than one time, consider a repair center for full diagnosis and -repair at -[http://wiki.laptop.org/go/Repair\_center\_locations](http://wiki.laptop.org/go/Repair_center_locations). |
