OK. Great. Is the attached version newer than the one in Sugar 0.88?? Because the latest dextrose image is mainly based on Sugar 0.88<br><br><div class="gmail_quote">2011/3/24 Richard A. Smith <span dir="ltr"><<a href="mailto:richard@laptop.org">richard@laptop.org</a>></span><br>

I'm planning to use different XO's, all of them 1.0 hardware. I<br>
definately won't be able to finish today because they all have different<br>
OS images and I think it would be best if I update them all (even for<br>
future tests). Maybe tomorrow, maybe monday.<br>

Yes certainly please use the same image on all of them. If you have to install software then please use the latest version of olpc-pwr-log. I have it attached to this mail.<div class="im"><br>

I think it will be very hard to perform the same test under the same<br>
conditions as you suggest because:<br>
- It will be very time consuming (though it doesn't need a lot of<br>
attention during the test)<br>

My goal is to automate the test and use a very short test window. ie 20 minutes or so.<div class="im"><br>

temperature is really variable (which is actually a lot worse for us<br>
humans than batteries ;) )<br>

Yes. Sorry my use of the word exactly was probably too strong. I don't mean that it has to be 25 degC ambient and only that temperature. The temp fluctuations in a air conditioned office should be within reason. I just don't want the profiles generated in an office and then the test run in a outside warehouse at 33C. Or the curves generated on a XO-1 with build 8.2 but the test run on a 1.5 with build 10.1.3. That sort of thing.<br>

The closer I might get, which I think could be pretty close is:<br>
- Install the SAME fresh OS image and firmware version on all the test XOs<br></div>
- Disable power management in every XO.<br>

and dpms. xset -dpms from the sugar terminal other wise the screen will turn off in 20 minutes and change the power draw.<div class="im"><br>

- The laptops batteries are mostly charged, so it will be a charge after<br>
discharge, so I think temperature there is less of a concern<br>
- Run the tests at the same time in every XO<br>

<br></div>
Yes. I believe that will work fine.<br>

Note: I'm getting on a plane in a few minutes so this will be my last e-mail until much later on today. Possible tonight or tomorrow.<div><div></div><div class="h5"><br>
