My dv6500 hp laptop cannot power with a flat battery after plugging into mains but will always show the blue light at the charging port, moreso it will eventually come up when i change the battery to another charged battery and then display charging at the notification bar when it boots up to windows, but will never comes up if i eventually makes the battery flat before charging

By saying flat, i mean when the battery has no charge or fully exhausted of its charges. the main point here is that without a battery, atleast my system should be able to power up when plugged to the mains, but it does not. how do i troubleshoot this.
