    I would please appreciate some feedback from fellow dv6000 series users on the following. If you have your laptop *unplugged* and do not use it, how fast does the battery loose charge even though the laptop is not being used?

    As an example, if I fully charge the battery on my laptop and then unplug it, according to the battery icon (hover over it in the icon tray), I will lose about 5% a day.

    I have run the battery checking utility that HP provides and it says the battery is OK. I think losing 5% a day is terrible and wonder if it is normal. Other devices that I own with the same type of battery do not self discharge this fast.

    I only use my laptop occasionally. If I leave my laptop in its case for a week and then want to use it, the charge level is only 60-70%. That sucks because even with a full charge these batteries only provide about 2 hrs max of use.

    Thanks for any feedback people can provide.

    i have a dv2500 with 6 cell battery , it also loses about 5% if it remains unplugged for a day. The charge level is about 95-97%.

    My DV9060 will go down to 50-60% after a week if unplugged.

    The discharging rate of your battery is not so much that it is leaking. It is more likely caused by the monitoring circuit that requires some power even on its idle state. However, I would be alarmed if the discharging rate is constant, as it would mean that there is a great chance of deep discharge that can cause pretty severe damage. But hopefully the engineers designing the battery are not complete morons to let the logic drain power to that state. :p

    Just to be clear, I am referring to when the laptop is supposedly fully shut down. Not in sleep, hibernate, or whatever mode. Full shutdown.

    The thought that there must be some sort of circuit running and consuming power had occurred to me but HP support did not indicate this was the case when I called them (for whatever that is worth).

    They are then most likely mistaken. I wouldn't imagine any notebook batteries these days to be so called 'dumb', seeing as how even handheld devices use smart batteries.
