Excellent.  Yes, you've found a potential cause alright.

Most other non-XO laptops won't indicate the presence of external power
if that external power is below par in some way, such as a bad
connection in a surge protector.

OLPC XO laptops are different, because they are intended to be charged
directly from a solar panel as well.  The difference means that an OLPC
XO laptop may indicate with the power LED that it is connected to power,
yet that power may not be sufficient to maintain the battery charge or
upgrade firmware.
