Well, i guess flashing led is not that power hungry?
I don't know of any computer that wakes up from sleep to complain about low battery. Back in the APM days, a BIOS option allowed waking up from sleep to hibernate to disk. It knew how to do so before there was not enough power to save everything to disk.

The ARM CPU is able to sleep and wake up much faster using much less energy than a typical PC. Anyway, the whole idea is to determine when it is not quite too late and complain then.
