Laptop HP ST09 long duration of life: battery secondary load problem

I recently bought a HP laptop computer ST09 long battery life, but it does not load how as I expect and cause me pain.   My computer is a Zbook of 15.

Both batteries are detected by my Windows 7 number of functioning, however when an AC adapter is connected only the original battery charges.  This way in order to charge the secondary battery, I need to physically disconnect the original battery and have only the ST09 in.

It is a very annoying procedure have to do whenever the secondary battery is discharged.  Is anyway at the same time load at the same time or just charge the secondary battery when the two are connected?

OK done something that essentially solved the problem. There is a 'Quick Battery Charge' feature that can be enabled in the BIOS which stop the primary battery to 90% charge and launched a secondary battery loading to optimize the charge cycle.

  • Portege M900: Battery and load problems

    I hope someone here could have helped me out in my problem. I bought my last Toshiba Portege M900 2010. I always want to plugin the charger my laptop when I am at work.

    It presents a time that when I turned on my laptop, the battery was about to be empty as the remaining 7%. I took my charger and plugged. After 5 seconds it turns off without any warning or so.

    I checked the lights in the laptop, the "light of load" is not on although charger is plugged into the outlet. I tried to use my Toshiba Satellite laptop charger and it worked.

    I tried to disconnect the battery from the laptop Toshiba Portege M900 its place and plug the charger again but there still does not turn on.

    So I took my Toshiba Portege M900 to nearest service center. But surprise when I arrived and on the problem of the technician, the laptop turned on after it was plugged. The technician said, he saw no problem because the laptop was in charge and it works right.

    But when I took it home, whenever I have remove the magazine from the taking of the laptop, it turns off immediately without any warning eventhough that battery is charged to 100%.

    And there were times, even if I remove the battery from the laptop but always plug the charger... the laptop will always be NOT PUT on.

    I tried to check the Toshiba PC Health Monitor, but it seemed that the battery works well. What do you think seems to be the problem? Is it the charger, the battery, or the power supply or the motherboard?

    > Is the charger, the battery, or the power supply or the motherboard

    I put t think its battery problem.
    Why? Because the laptop does not power upward even if the battery is removed but connected to the power adapter.

    Jack _Power? _
    Perhaps. It might be possible to equip jack or connection between the power supply and the card mother isn t ok.

    _Motherboard? _
    It could be a problem with electronic control gear that is part of the motherboard but once more; It's just an idea

    _Charger/AC adapter? _
    Hmm, you said that the adapter has been tested with another laptop and it worked. So maybe it s question no AC adapter.
    But are you sure that other phones have not run to the battery power?
    The adapter has been tested correctly? It is an open question.

    Another idea:
    What version of BIOS you have installed the M900?
    Find an update of the BIOS for the M900 protégé
    + Updated BIOS version 2.40 for Portege M900 and Satellite Pro U500 (for PSU56 *, PSU5C *, PSU5J *, PSU5Q *, PSU86 *, PSU8G * and PSU53 * ONLY) +.

    You will find a detail on the correction of a problem:
    + System can not turn on without using the AC adapter / CC after the battery has been detached and attached again. This problem has been fixed. +

    Please check if your Portege M900 is one of the mentioned models and check if a BIOS update is available for your device.

  • Equium A200: Matter of life battery

    I just bought this new Equium A200 computer laptop and the battery runs really fast - at least 1 hour. I have to keep constantly plugged in to keep his performance.

    I have implemented energy saving battery, but y at - it an extra battery that I can buy to improve and do better? Or is there anything else I can do with the settings to make this race more effectively? I need to take a lot and right now that it would not last very long and defeas the object to have a laptop.

    The battery life depends on the use of the laptop! So it's not easy to say how long the laptop needs to run on the battery.
    However, if you want to run the laptop a little more time using the battery then, you could buy a stronger battery which delivers more power for a long time
    You should take a look at the value of mA; more better

    Also please don t forget that the Vista operating system needs more power as an early OS like XP.
    Vista needs more power because it wastes more computing resources.
    I read that a same notebook would run 2 times longer on battery with preinstalled W2K or XP.

  • How to maximize battery life battery with Lithium-ion batteries?

    Hi all

    There are discussions severay about the duration of battery life.
    Toshiba said on http://support.toshiba-tro.de/kb0/FAQ35007L0020R01.htm that:
    Discharge the battery completely before recharging, will allow the battery to be charged to its highest capacity
    But this and other points do not comfirm maximum lifetime of the battery of the http://en.wikipedia.org/wiki/Lithium_ion_battery information

    Question: What is the best option to maximize battery life battery with Lithium-ion batteries?

    Hello

    I wonder why you n check the user's manual t or have you checked it?
    The manual provides many useful tips, it confirms the information provided in document Toshiba

    However, I assume that the information provided in the document of Toshiba relate to Toshiba laptops and the wikipedia article is general information

    I have several laptops at home and I still have the battery charged and completely acquitted in the first three, four times.
    You know, you can compare the situation of a laptop with the batteries of mobile phones battery. It s always advised to load and unload completely the battery because of the effect of stack memory.

    But from my personal experience each battery loses life after 1 performance 1.5 year.

    There, Windows XP had a battery drain fix (patch). How can I determine if this hotfix is installed on my laptop? I haven't used a battery for years, but I would like to order a.

    If the hotfix is not installed, how can I get it to install?

    Your question is too vague.  Most of the life themes battery by Windows XP tasks occur only in some computers - and yours may or may not benefit from all the suggested fixes.  In addition, some of these plots have been released a long time ago and were likely incorporated into a later Service Pack.  You should have installed Service Pack 3 for Windows XP 5 years.

    If you want to use your laptop as a portable device, I suggest you buy a battery - not the cheapest possible one - and use it for a while.  If you experience shorter than the normal battery life, you can ask for help then or read through the results of this research--> http://support.microsoft.com/search/default.aspx?query=battery+life+xp&x=4&y=8&mode=a&spid=global&catalog=LCID%3D1033&wa=wsignin1.0

    Hello

    What to say dude battery working time depends on the use of the laptop and on the performance of the battery.
    I put t know what exactly the battery delivered with this laptop, but as far as I know it s a common standard battery. If you want to use the laptop much more time, I advise you to buy the stronger battery; for example, with 6000-8000mAh with Adapter Cable.

    By the way; You can configure the use of battery power in Vista power options.
    If you wish, you can create a new configuration of the plant to get the best performance from the battery.

  • How long should take a battery to charge

    Thank you

    Mark

    Hello

    What is the power rating of your charger ? 90W charger, it normally takes up to 4hrs as fully charged. 65W charger time would take more time, up to 6-7 hours (overnight). Faster for MU06.

  • automatically optimize for costs of life battery batt to 100% within the parameters of the power manager

    In the settings of my ThinkPad Power Manager W530, I chose the option "automatically optimize for life battery" (battery-> maintenance-> Mode of Charge of the battery). Nevertheless, he always fresh and keeps the battery at 100%. Is it normal for a battery 9 cells?

    Link to photo

    But many articles and discussions here at the forum State, actually in charge at 100% is not tor good battery life (see for example this article http://forums.lenovo.com/t5/Welcome-FAQs-Knowledge-Base/How-can-I-increase-battery-life-ThinkPad/ta-... ). Do not miss anything?

    Thank you!

    Note of the moderator; image (s) for a total of > 50 K converted for the programming of the Forum rules

    No matter how many charge cycles the battery on it, just the time where you change the batteries maintenance mode. If you have configured to maximize battery life, the battery may charge at a lower percentage (somewhere around 90%, more or less a few percentage points), but will show this figure as "integral" or 100% for the system. If you change the mode to load completely, then the maximum capacity will change to read the actual capacity of the battery.

    The only way your situation would be a concern if, after setting the battery in order to maximize the battery life, then using the system on battery and load up once again, the battery always charged up to the full 94 w/h instead of reducing the number.

    Hi,

    It would help if you provided the WHOLE message and CORRECT, including all codes completely written word for Word - this can often help us identify the problem.

    If you think you know when it started, and it is recent, then see if a system restore to before that the problem will work.  If you use Windows 7, seehttp://www.sevenforums.com/tutorials/700-system-restore.html. If you are using Vista, seehttp://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/. If you are using XP, seehttp://support.microsoft.com/kb/306084. Sometimes this simple process made the rounds and sometimes that doesn't help - but it is easy and worth if she has recently begun.

    When everything is fixed, get rid of any program you use to do a cleaning of the registry.  Even if it wasn't the cause, it could easily be the next time.  It is poisonous to your system and is not necessary because Windows is a research work on its own.
