I don't see anything that looks obviously wrong.  So here's a test to see if the EC is going to sleep or not.  Run the battery down to where the red LED is active.  Then power off the laptop.  If the EC goes into stop mode the red LED should go out after a few seconds.  If you press a

This battery is really strange... After an O/N with the battery out of the XO tried to run it down and suddenly none of the info in /sys/devices/0.baterry/power_supply/olpc-battery/ was changing after an hour of CPU burn and the battery was showing as Full Shutdown and removing the battery

I'm very 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. Hard FP status depends on if Yioryos is running 11.3.1 or 12.1.0.

then.  Do you have a XO-1.5 or 1.75? Something with an EC serial connector loaded? I have the adaptor on the J1 of an XO-1. Will it do? No. If not, where is CN24? (a picture or a reference to the XO-1 board will help) XO-1 did not ship with an EC connector loaded. That's why I asked about

  Most of the test had empty values but the informative ones (below) show that the XO-1.5 is better in basic integer operations and memory bandwidth while the XO-1.75 is better in float and double operations as well as in memory latency. I'm not sure how much this means for real life
