I should be asleep, but instead have been zigzagging through old http://xs-dev.laptop.org/~cscott/xo-1/streams/staging/ staging builds testing WPA and the dialogue cancel dance for the last 4hrs: 790 working 4 working 5 working 6 working <- 7 intermittent 11 intermittent 15 broken 800 broken Intermittent means it can occasionally associate with a WPA access point with no cancel dance, but usually I had to dance. Broken means I had to dance every time. One thing I noticed when testing the working 4, 5 and 6 that may help, is that if you do naughtily click an already connected WPA access point you'll get back to one round of the WPA cancel dance. If you make sure you first select 'disconnect' then click the AP again, you get correctly re-associated, no dance required. This suggests that clicking a connected AP should either do NOP, or should at least disconnect properly before trying to connect again.

The ACR register will decrease when you use the battery outside the laptop. The EC periodically takes a snapshot of the SOC and the current ACR and saves it into the EEPROM. When you insert a battery the first thing it does is compare the current ACR vs the saved values and then roll the SOC up or down depending on the difference between the values. -- Richard Smith One Laptop Per Child ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

In q2e32 I've pulled in some of my batman.fth stuff. As James mentions the EC won't try to charge if it thinks the battery is full because the battery full flag is set. I've added some commands that let you reset that flag. ok batman-start ok bg-clr-full-flag ok ec-reboot The EC should then charge your battery. -- Richard Smith One Laptop Per Child ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Tested 6 times in a row for open access, WEP, and WPA, and some misc. comparative runs with an XO running 8.2. Access point is a D-Link DSL-G604T (Wireless ADSL router). Summary: 8.2.1 has regressed relative to 8.2 for WPA access points. You now have to enter the security string; it will fail to associate and prompt you for the security string again; you have to cancel this dialogue; it will start trawling for a mesh; you have to click the AP again; it will now connect. Open access == First connection: 4 successful auto associations, 2 times a 2nd click on the AP was required before it would associate. After OS reboot: 5 successful auto associations, 1 failed to re- associate and required clicking the AP. After restart of Sugar UI: 6 successful auto associations. After sleep: 5 successful auto associations, 1 failed to re-associate and required clicking the AP. WEP security == First connection: 6 successful WEP dialogue followed by association. After OS reboot: 6 successful auto associations. After restart of Sugar UI: 6 successful auto associations. After sleep: 5 successful auto associations, 1 failed to re-associate and required entering WEP key again. WPA security == First connection: Prompts for the security string and then fails every time, until you subsequently click a dialogue cancel button, then clicking the AP again will associate (8.2 connects without a hitch). After OS reboot: A 6 attempts failed to re-associate and shows the security string dialogue, clicking cancel and then clicking the AP again will re-associate (8.2 connects without a hitch). After restart of Sugar UI: 6 successful auto associations. After sleep: All 6 times dropped back to mesh, 3 of those times manually clicking the AP auto re-associated, the other 3 times prompted for the security string which you had to cancel then click the AP again (8.2 did not automatically re-associate, but clicking the AP connected immediately with no dialogues). Hope this helps, --Gary P.S. Interestingly we had what seems to be the same behaviour, but with WEP, for a while early last year in the (long) run up to 8.2. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Discharge to 90% and then charge to completion. Power off, then remove the battery. Travel as fast as possible to the place that does not have electricity, do not delay by a month. Insert the battery and power on. You will have the most minutes of use. > And if it is not 'well charged up', what do I need to do to make it > so? In particular -- if it *were* 90% "charged up" when I took > it off the shelf, would I have to fully discharge it in order to > then "charge it up" (using the XO as the 'charger') closer to 97-99% ? No. Assuming a battery that has only been used in the XO, you need only complete one charge cycle, from orange LED to green LED. Since you cannot cause this cycle unless the state of charge value was low enough, you need to manipulate the state of charge value down, and the only way to do this in the design is to discharge for a short time. Usually about five minutes, but it depends on how busy the XO is. -- James Cameronmailto:qu...@us.netrek.org http://quozl.netrek.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Even if they get more "charge", the battery doesn't hold it. Or perhaps the software estimated the capacity a bit too high. In short, the % you see is a fiction, a bad simplification. This is increasingly apparent as you use older batteries, and in general as you gain experience with different batteries... m ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Have you tried either of the tools/procedures at: http://wiki.laptop.org/go/XO_LiFePO4_Recovery_Procedure Either olpc-pwr-log (download and run in terminal) or bat-recover (download a batman.fth file and use from Open Firmware), display actual charge going into (or out of) the battery, so you could use either of them to charge and see when your battery stops getting any more juice. Of course, without testing full discharge/charge cycles occasionally, you could never be quite sure where a batteries max is/ was (but that just takes us back to the email loop on precision). --Gary > And if it is not 'well charged up', what do I need to do to make it > so?

[ANNOUNCE] Sucrose 0.84 Release Candidate 1 (0.83.5)
Dear Sugar Community, This is Release Candidate 1 for the upcoming 0.84 Release - see [1] for more details. Only two more weeks to go in this release cycle. Please test this release and report all the bugs you find that we are able to fix them in time. A friendly [2] will be available to triage those bugs accordingly and the developers can never have enough bug food. If you have non-bug feedback about features you can use the sugar-devel mailing list to share it with us. From a user point of view we want to highlight the following changes that have been made in this release: === Journal === The translation of the dates in the Journal is working now again. Please verify with your favorite language that this works for you. A 'Clear search' button has been added to the 'No matching entries' message, following Eben's specification. Also the space used and left is now displayed in the volume palette in the Journal. Journal entry palette The journal entry palette has seen some great improvements. We have a 'View Details' option that brings you to the details of the entry directly. Also the icon for the file transfer was designed and added by Gary C. Martin. Furthermore you do not need to go to the detail view any more to select the activity you want to start or resume the entry with - this option is now available in the palette as well. === Naming Alert === When you stop an activity from the Frame the activity is resumed and one can refine the activity metadata in the Naming Alert. As well a saving error of the activity will not prevent one any more from closing the activity due to the Naming Alert. === Palettes === There were some positioning issues of the palette that got fixed. Please report back any issues you still find. Another palette related fix was that on right click on an Access Point icon we do reveal the palette as it is the behavior in all the other places in the UI and do not try to connect to the Access Point. === Keep error when displaying a file in Browse, Read, ImageViewer === This is one of my favorite fixes as this has been broken for quite a while. When trying to display for example an image in Browse or the ImageViewer there was an keep error when closing the activity. === Resume activity === Last release we added the ability to resume an activity by default instead of creating a new instance. The list of the available entries in the palette when you hover of the activity in the home view is now updated directly. As this is an interesting new feature, we would like to hear about any issues you might have with it and positive feedback of course as well. === Control Panel === We now hide any OLPC-specific fields on non-xo machines. For example in the 'About my Computer' section we display the build dependent on the distribution (i.e. Fedora). As the Power section was only relevant on the XO, it is hidden in non OLPC distributions. === Frame Devices === Right-clicking on the speaker device icon does not mute the speakers anymore. === Clipboard === Several fixes were made to the detection of images dragged and dropped to the clipboard in the Frame.
