On my older 48SX it's the top-left foot, but on my newer 48SX (and I guess all 48G series), it's the top-right foot. Look for the letter "R" next to the hole. The "hardware reset" by itself forces a warmstart; useful when things are so fouled up that [ON][C] together won't do it.
It wouldn't hurt to check that the batteries are actually good. I once had a bad experience replacing low "N" cells in a 28S with new ones, and found that the new batteries were almost completely dead; not even enough power to retain memory. I doubt that that would happen with "AAA" cells, but if there are children around, they might replace the batteries in their toys and put the old ones back in the box.
