battery being consumed even in shutdown/hibernate/pc complete powered down state?

[silverstone75]

HI! I am owning an HP dv6 3008tu notebook since the past few months. Its working fine for all my (not so heavy) needs. With the help from HP support assistant software things are much in control.  I am satisfied with the product except just a single but extremely curious issue & that is of battery resource. Since I am using it as a desktop, so my battery needs are bare minimum. But still then I am finding that system is using the power from battery as well, though occasionally.

My observations in this regard-

1.       Even when 100%  charged, after 3 days it use to dip to 94% and start charging again to 100%

2.       As a matter of caution I am calibrating the battery once in 2 months & the status of battery on support assistant is good. My calculation is on the whole I would have used not more than 18-20 life cycles of the battery at the maximum.

3.       Recently I happen to download the HP protect smart hard drive protection version 4.0.2.1.  But after that battery has started troubling me. Now instead of 3 days it is dipping daily to 92-93%  (for 2 days 82-83%, for 3 days 72-73% and so on). It usually happens just at startup in morning/first use in the day i.e. once in 24 hours, as if some timer is set. I have tried newer version 4.2.2.1 as well but no avail. Now I have removed the driver as well as software but the battery issue still persists.

4.        It seems as if system needs resource more than it has and is draining it from battery even when a/c connection is very much on. However the windows 7 admin/performance tools do not identify any such issue and reports all is fine, same is for HP support assistant.

                           I have even disabled this device (now unknown device) in device manager. But resource setting is still pointing to irq 017(23). Is it relevant or should it show - no resource is being used?

5.       On the whole I have kept my system quiet clean and have limited software only. Earlier also once such a thing happened in the earlier days as well, then the support assistant helped by tuning up and downloading the appropriate drivers and things remained fine after that. But this time even support assistant is found dumb.

My expectations & suggestions-

1.       Please help to diagnose this issue.

2.       I have removed the battery for the time being.  Here when battery is removed negligible charge is lost even after days together at a stretch.     Also I have a few suggestions in this regard-

a.       HP must provide an additional battery compartment cover, just a plain simple cover, even may be as an accessory that could be purchased from retail outlets.

b      HP should provide a switch, hotkey (or may be a software!) so that without removing the battery from the compartment I could stop/bypass the battery use if I so wish, especially when it is shutdown/hibernating & is not in use. It will be a great relief.

This is common with Lithium Ion batteries and there is nothing to worry about. There is a a slow loss of charge when battery is not in use.

Some loss in charge will be there, that I understand, but the trouble is when battery is attached the loss is 8-9% per day whereas when the battery is removed the the loss in detached battery is only 2-3% even in 18-20 days. So the trouble is somewhere in the system itself, especially when once earlier also I got into such situation but then HP support assistant tuned up the system and replaced some drivers and the result was immediately noticeable in the next 3-4 days itself, but not this time.

             My intuition is it is the result of 2-3 bad software and the 3D drive guard/ HP hard drive protection is not the only culprit. Now how to locate/ identify the energy suckers is the real challenge. I have uninstalled all those I recently installed but no respite. It is here I need Hp expert's help in identifying those troublemakers!!!!!!!

Depending on temperature and heat level of battery, the battery leakage can increase. Also when you connect the battery inside the notebook, do you keep the notebook in sleep/hibernate/shutdown state?

[silverstone75]

In 80% cases it is shutdown state & in 20% cases it is hibernate state with main power supply off always. But the result is same in both cases.

I never use the sleep state in any case.

Hello experts, can you help me?                   I am in search of a comprehensive & a sureshot solution to this issue!!!!

If support assistant can once identify it earlier, there is no reason to believe that it is beyond reach, just this time SA is bit unlucky!!!!!!!!!!!

My basic search is to identify the power consumption of softwares, OS, drivers  etc. It could be with the help of HP's or some external software you may suggest.

Also though not in my laptop model's recommended list but I have heard of an HP power assistant for premium model or an HP software framework. Could these help in some way?

Hi experts, is any one there!!
