For batteries with the ExpressCharge feature, the battery will typically have at least an 80% charge after about an hour of
charging with the system off, and fully charged in about 2 hours with the system off.
Enabling ExpressCharge requires that both the computer and the battery used be ExpressCharge capable. If these
requirements are not met, ExpressCharge will not be enabled.
