 Hello,I've just joined this list which I discovered after coming across
this exchange trying to troubleshoot my own problem via google.  This
problem seems quite similar to my own.  I have logged a ticket for my own
case and attached the files requested in the instructions.  Is what I post
below  (and described in the ticket) what I should be doing or are there any
updated ideas on this problem?  Thanks very much for any help you can
provide. My daughter absolutely loves her XO and I hope we can get back to
using it without being plugged in soon.

my ticket:

Best regards,
Jason

Interesting.  Yeah. Something is up.  That 4th number is battery current

in uA.  So if it does not have 6 or 7 digits then you aren't doing much
in the way of charging the battery.

Make sure that you a copy of the battery.dmp file into the help system.
  I think all you need to do is send mail to help at laptop.org
<http://lists.laptop.org/listinfo/community-support> describing

that its a dump of your batteries eeprom.  We should get it all route to
the right ticket.

I made a tweak to batman.fth  Grab the latest copy from dev.laptop.org
and re-run.

But change the procedure a bit.  This time after you run 'bat-set-low'
and remove all power from the laptop.  But the battery back in (No ext
power) But don't power up.  Watch the battery light and see if it turns

red for 10 or 20 seconds and then turns off.

Then you can repeat the steps.  ie (remove battery, power up, run
logbat, insert battery)

And actually if the same thing happens then repeat the procedure several

times to see how consistent it is.

>* 1199993698,91,5572350,-943691,2318….(I wasn't writing quickly
enough to get these last numbers – I haven't figured out how to find
the bat-log, so I was copying those numbers by hand)
*
You use olpc-logbat as root so its in the root users directory /root

do this:

start terminal app
'su -'  (This makes you root)
cp log-* /home/olpc
chown olpc.olpc /home/olpc/log-*

Now you can find the log files in the olpc users home directory.

>* I started getting the same error messages as I did when it couldn't
find the battery (because it wasn't inserted)
*>* I got a few more lines that looked normal, then another set of
error messages associated with not being able to find the battery.
*
That version of EC code has some periodic timeout issues.  So when
logbat constantly queries the battery you will get times where you don't
get any info.  Its ok.  Its fixed in my new (unreleased) EC code.
