If you let a Lithium Ion cell phone battery die COMPLETELY, not just to zero%, but beyond that(and yes, it can happen), you phone may not be able to charge it. This is a BIG problem with both HTC made phones and Windows Mobile, they do not posses a strong enough charging circuit to be charged over USB. What you have to do, is either connect the phone to a wall charger that outputs at least one amp to get it to charge, or jump the battery off with another Li-On, or with a 9 volt battery to get it a tiny bit of charge, and then your phone will recognize it.
“The HD2 is a magnificent monster. It is a hulking, intimidating, massive slab of a gadget. If you think the device looks big in photos, it's nothing compared to how it seems up close.”
