My experience is that OFW warns if no external power is present. But it seems to be silent on the main display about the low battery reflash failure condition unless you attempt to reflash firmware from the "ok" prompt, or are not in the TS=SHIP (and therefore in a verbose boot) state.<br>

<br>
</div>No. There is no such threshold in Open Firmware.<br>
<br>
Open Firmware does not check the state of charge when assessing<br>
whether there is enough power for reflashing firmware.<br>
<br>
Instead, Open Firmware relies on the battery status flags provided by<br>
the embedded controller:<br>
<br>
- external power must be present,<br>
<br>
- a battery must be present,<br>
<br>
- the battery low status bit must be cleared.<br>
<br>
Therefore on your SKU296 the battery low status bit must have been<br>
set.<br>
<br>
Can you provide power logs from the duration of the olpc-update?<br>
<br>
You can find further information in the embedded controller source,<br>
for the bit name bat_low<br>
