You turn off the XO at night and then in the morning the battery is
12% less?

- Battery does not lose charge outside the laptop.
- Tested the battery in 2 different laptops and the loss is the same.
Roughly 12% overnight.
- A different battery in those same laptops does not lose 12%

into
stop mode the red LED should go out after a few seconds. If you press a
game button the EC should wake up briefly and the led will turn back on
then in a few seconds go back out.

suspect of this measurement. The 1.5 has a hardware floating
point unit and the 1.75 is still using soft-float. Its extremely
unlikely that the floating point performance on 1.75 is better than the 1.5.

hook up the EC serial port and log the output. Then charge up the
battery. b3 to get some readings. Disconnect external power and then b0
. You should see it go into stop mode. In 24 hours wake the EC up do
b3 to get a 2nd set of readings and then send the log output.

but the output is not valid.
Perhaps your comm settings are wrong? 115200,n,8,1 is what they
should be set to. Its exactly the same as if you were connected to the
OFW or Linux output.
The EC output is readable text and if you press enter with no command
you get back a prompt.

If you want to understand whats going on the please run olpc-pwr-log so

things based on those values.

since a reset fixes it I wonder if there is something that is going

too much current from the laptop and forcing a reboot. It
doesnt matter which usb port i plug it into.
What production rev model is your 1.5? Did you get it from the
developer program? I have a vague recollection that some of our earlier
runs of 1.5 had a USB issue like that.

was wondering if you could leverage
the existing infrastructure for this.
The thread dies after that. So I think anyone wanting this to get
integrated as a stock feature should investigate if you can use a NM
hook to send the DBUS message to powerd to inhibit.

for a setup
like Adam is describing in Haiti where they have laptops in the mix that
are secure. Unless they first un-secure every laptop a custom OS build

them a Haiti key thats installed via keyjector.

or provide a keyjector to insert custom keys, upon their request.
Nod. Kejector for small deployments is new to me. I thought keyjector
was only for special cases.
I don't think most of the folks on say the support-gang list have any
idea that keyjector is an option for them.

We would be interested in a confirmation or otherwise of this in the power

I guess you are comparing to 13.1.0 build 36?
The big difference here is that 13.1.0
are behind a 71k laptop lease generation request. Which looks like
it still has another 40 hours to go before it finishes. If you
absolutely gotta have it now then send me your serial number and I'll
see if I can get it generated for you.

to the EC about the state of the CPU booting. It's mostly just
EC timers. I won't say its impossible but I don't have any memory of
anything like that and a quick look at the system power up code doesn't
bring back an memories.
