Is there any way to check the remaining battery life on an NEC Mobilepro 
780 running NetBSD? It seems like the "apm" program always reports 20% 
battery life, no matter how long I've been using the machine off of the 
charger. Is there something else I should be using instead?

(Sorry if this is a silly question, but for some reason I can't find 
anything in Google and I'm new to NetBSD on portable gear, so I've never 
had to do this before.)
