Power Control in Power Assistant

[zaanton]

hi,
last power assistant has this power control feature, in which is included battery charge control. According to hp it allows to schedule a time period in which AC power charges the battery. It is supposed that no other time period will battery charging be allowed. But it is not working. Battery is charged beyond scheduled time period. How to make this feature working? I have set in Bios power control. My laptop is 6465b.
