</div>The full stop condition for battery charged is when the constant<br>
voltage taper current drops below .12. I suspect you have some sort<br>
of cell defect that keeping the taper current above that.<br>
<br>
Next time you are using the machine stop powerd and run olpc-pwr-log<br>
in a terminal (you can use it normally) and let it run down until it<br>
powers off. Then remove the battery, power back up, run olpc-pwr-log<br>
again and then re-insert the battery. Let it charge until you see the<br>
got to 100 and the 3rd and 4th column of numbers reach some sort of<br>
steady state where they don't change much. Ctrl-C and then send me<br>
the file.<br>
<br>
FYI. Col 3 is voltage in uV and col 4 is amperage in uA.<br>

<br></blockquote><div>Darn, I did something else first.<br><br>Yesterday, before I left for the day, I figured what the heck, let me try and load batman.fth and run the bat-recover command. That started off cranking about 30-35 uA, and the uAh was increasing by about 1uAh per minute. But when I left after about 90 minutes, the uA was seemingly decreasing and was averaging about 17-20 uA, and the uAh was now only increasing by about 1uAh every 3 minutes.<br>
<br>When I returned this morning, it was running at about 1.2 uA, and the uAh had stagnated at 98.75. (The routine was running in total for about 14 hours)<br><br>The indicator was still yellow. I removed the battery ( to get the keyboard back ) when I reinserted the battery and .... the led turned GREEN. I then went to my email, and alas then saw your procedure. Sorry.<br>
<br>So, I have put a little tape indicator on the battery, and if it misbehaves again, I will instead run what you sent me. (Unless you think it still instructive to perform that test, but I fear my dabbling may have trumped the evidence.)<br>
<br>Thanks for your quick reply, sorry I didn't get to it first to provide a better analysis.<br><br>Cheers<br><br>KG<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
