Q2F12 added support for automatic power down if lid is closed while at<br>
ok prompt, per ticket #11095, svn 2991. If you have been using<br>
previous firmware, you may never have seen this message.<br>
<br>
It has been a feature of XO-1.5 and XO-1.75 already.<br>
<br>
On XO-1, the lid switch is wired to the CS5536 companion chip, as well<br>
as to the the embedded controller. Open Firmware is reading from the<br>
GPIO pin array in the CS5536. Hal observed a confused embedded<br>
controller or battery error may trigger this issue.<br>
<br>
Kevin, Robert, please remove the external power, and the main battery,<br>
wait ten seconds, then reinsert both, and see if the problem persists.<br></blockquote><div><br></div></div><div>Problem persists.</div><div><br></div><div>Just a reminder this lid message only appears upon entering firmware after a reboot from linux. Doesn't happen on entering "reboot" from firmware or a cold start. Noted one other "symptom": when I do the reboot from firmware, I do hear a little 'click' as the battery LED flashes, I don't hear that click on the reboot from Linux. It occurs whether doing a restart from the GUI on Linux or entering "reboot" from terminal.</div>

If it does, please get to the ok prompt, type lid-off and press enter<br>
(to stop the timer), then test the lid switch like this:<br>

This will print ffffffff when the lid switch is considered closed, and<br>
0 when the lid switch is considered open.<br>
<br>
Waving a magnet against the front bezel above the microphone is a<br>
useful way to test the switch without having to close the laptop. The<br>
switch works best with the north and south poles of the magnet<br>
pointing left-right or right-left. You'll soon learn which way works;<br>
I don't have a labelled test magnet here, I just know it works only<br>
one way.<br></blockquote><div><br></div></div><div>I'll search for a magnet; dont have one at my desk.</div></div></blockquote><div><br></div><div>At the risk of too much info. I have also noticed that the lid-off message when entering firmware does not ever happen on the XO 1.5. </div>

The case magnet is to the left of the touchpad. Drag a USB drive over<br>
there to find it; a typical USB connector will be attracted.<br>
