HP - 15 laptop: the estimated time to battery is incorrect!

I recently got a new HP 15 notebook and I noticed that the estimated remaining battery time acted strange. When the battery is at 99%, the estimated time is 5 hours but 98%, 7 hours; and it's not always 7, I saw 9 as well. The point is, my laptop was caused the range estimated by a draw.

Hi @Mannat

Welcome to the HP's Support Forum!

I understand that you are facing problem with the estimated time of battery.
I'd be happy to help you.

Please follow the steps below
Step 1: We will try everything first uninstall and reinstall the software of battery.
Step 2: Click on Start and type device in the search for field, and then select Device Manager.
Step 3: In the batteries category, right-click in the list of Microsoft ACPI compatible with battery control method and choose Uninstall.
Step 4: WARNING: Do not remove the Microsoft AC adapter driver or any other compatible ACPI driver.
Step 5: In the taskbar from the Device Manager, click on search for the hardware changes.
Step 6: Windows will scan your computer for hardware which has not installed the drivers and will install the necessary drivers to manage the battery power.

I also recommend the battery calibration.

I found a few Documents Support HP's wonderful for this.

    Hi Memo

    Not sure I've ever seen it 2-3 seconds (past), and I worked on some sites with substantial material.

    40 seconds isn't too bad.

    Also consider this. If it's the first payroll run for an assignment given in the tax year then there will be a certain amount of overhead recovery with initialization balance etc. This is true for pay normal works as well - the first run in a new tax year will have a more runtime due to the way in which the dimensions of assessment of the tax year are 'reset' etc.

    Most people would probably not use Express to treat someone through several consecutive periods of treatment, but if you have a test/development environment you might run your first Express for an assignment and then move on to the next pay period and run a later Express. I expect there will be an improvement in the run for the second time (assuming that its still in the same tax year :))

  • Question on the working time of battery on Portege R500-12 s

    Hello

    We have a R500-12 s - Core 2 Duo U7700 1.33 GHz - 12.1 "TFT bought a few months running windows XP and it never watch a few hours of battery life remaining on the same XP battery indicator after a charge complete.

    This happens with the power plan best setting for the life of the battery under XP.
    I note that the Toshiba sales presentation text mentions a LIF battery of up to 8.5 hours, but can anyone else advise what dead battery they see leaving their R500?

    I put a battery calibration program in control panel/menu start - everyone has one? Thanks in advance.

    Hey Buddy

    You mean you want to run the laptop on battery for more than 8 hours?  :|
    Sorry, but I can't believe that I doubt that this is possible using the standard battery.

    AFAIK the R500-12 was equipped with the battery of 3 cells 2900mAh.
    Maybe you can run Notepad longer with a battery of stronger but I n t think only a 3a battery enough power for 8 hours.

    Visit the Web of Toshiba Options & accessories and you should find some stronger batteries for this laptop.

  • Whenever I turn on my laptop, the system time is the same as when I stop it, how to fix

    Hello

    I have HP DV6 - 2130ca. I recently had a bug that were not work my quick commands. A support forum, I got to know that if I take my batteries for laptops and power and press the power for 30 seconds he'll fix it. Well, he got the problem solved but since then I am having a problem.

    Whenever I turn on my laptop, time is the same as when I stopped him. For example, if I 'Shut Down' or 'Sleep' at 2: 00 and turn it on, to 17:00, the time would still be 14:00 on laptop.  I tried Googling and found a lot of answers slightly different questions on several support forums by using the Task Scheduler to schedule a task to update time only every 5 min etc, but that did not work.

    If I update manually time using time settings Internet, set time until I turned off my laptop or put it to sleep.

    Please help me. Thanks in advance :)

  • "Movie Maker" estimated time remaining "continues to go to the top

    I made several videos to movie maker in the last two weeks. However, it is the longest (16 minutes). All are the same format (wmv). I have xp pro, service of acer extensa 4420 computer laptop pack 3 dual core processor 1.90 ghz, 1.75 g of ram.

    After editing my video with video clips and background music I click on save to computer (recommended) in the format wmv, same destination as other videos. But when I click Save it never gives me... 15% all the "estimated time remaining". 5 minutes". The remaining time still to go upward and upward and upward, never back down and record my video.

    Any help would be great without the comments of "upgrading to windows 7. I'm currently not financially able at this time.

    Spent several days here working on this project and would not start again with another program. Is there the codecs or plug-ins, I may be missing?

    All the video wmv format, all the sound elements are mp3 that I use.

    Thank you people!

    The problem you describe usually happens when the
    source files are not compatible with Movie Maker.

    The solution is to convert the source files for a
    compatible format before importing them into Movie Maker.

    Several formats are apparently compatible with
    Movie Maker, but the most reliable choices are:

    Photos - bmp
    Video - wmv
    Audio - wav, wma, wmv

    Since your music files. MP3, which would be the
    place to start... try converting them to the. WMA
    the format and re-import them in Movie Maker.

    There are many converters available on the net... the
    the following link is an example:

    (FWIW... it's always a good idea to create a system)
    Restore point before installing software or updates)

    Format Factory (freeware)
    http://www.videohelp.com/tools/Format_Factory
    (the 'direct link' is faster)
    (the file you want to download is: > FFSetup295.zip<>
    (FWIW... installation..., you can uncheck
    ('all' boxes on the last screen)
    (Windows XP / Vista / 7)

    First... after the download and installation of Format
    Factory... you can open the program and
    left click on the toolbar, the "Option" button and
    "Select an output folder to" / apply / OK.
    (this is where you find your files after they)
    are converted)

    Drag and drop your music files on the main screen...

    Select "while"WMA"/ OK...

    Click on... Beginning... in the toolbar...

    That should do it...

    If the problem persists... you can have one or more
    corrupt. WMV files.

    In many cases, I found that convert a. WMV file
    to the. WMV format could produce a new version of the
    compatible file. Sounds redundant, I know, but it
    can work.

    Microsoft Expression Encoder 4 can perform the conversion.

    (FWIW... it's always a good idea to create a system)
    Restore point before installing software or updates)

    Download Microsoft Expression Encoder 4 with Service Pack 1 (SP1) (freeware)
    http://www.Microsoft.com/download/en/details.aspx?displaylang=en&ID=24601

    Also... it can depending on the version of Movie Maker...
    help to go to... Tools / Options / Compatibility tab and left
    Click the restore all default settings / OK.

    +++

    If you want to try Expression Encoder 4 following
    info can be useful:

    Start Microsoft Expression Encoder 4
    (Start / programs / Microsoft Expression /)
    Microsoft Expression Encoder 4)

    On the "Load a new project" screen...
    Left click... "Transcoding project '...

    When the program opens, click on... File / import...

    Left click (highlight) the. Left and WMV file, click the Open button.

    You will see the file in the "Multimedia content" pane

    In the right column... left click on the tab "Output"...

    Open the drop directory window and choose an output folder.
    (This is where you will find your converted file)

    On the left, click on the button "encode".

    Wait... video encoding CPU intensive and can
    be a slow process. It is always best if you do not have
    multi-task while files are encoded.

  • received email does not display the exact time

    My computer is a Microsoft windows XP version 2002.  I use Enternet Explorer Windows to my email.  The problem I have is when I get e-mail, time showing when it was sent is not the exact time.  This happens on all the emails that I receive.  For example, if I received and email this morning the date would be today, but the time to show it was sent at 14:45.  I tried to go to the toolbar to adjust the date/time.  Date and time are correct on my computer.  I don't know where else to look at in order to remedy the situation.  Unfortunately, I only have basic info when it comes to solve a problem on my pc.

    Hello pinnaclelil,

    Thank you for visiting the Microsoft answers community.

    ·         Is - this problem within an application on your system (outlook, outlook express, etc.), or a web-based E-mail (hotmail, gmail, etc.)?

    o If you use web-based e-mail, go to the options in your account to check your time zone settings, otherwise follow the steps below.

    ·         This problem occurs with all received mail, or just a sender?

    o If it is a question of a sender:

    § The sender to verify the time and time zone on the system settings.

    o If there is a problem with all the mail receipts.

    First, § lets go ahead and check your settings again.

    § Double-click on the time located in the taskbar. Check your time and date to ensure that they are configured correctly.

    § Click the time zone tab. Make sure you have your correct time zone selected.

    § Click OK.

    § Then, the mail time server is set incorrectly. In this case, you will need to take a look on the headers of messages in order to determine if this is the case. If it is established that the mail server is configured incorrectly, you must contact the owner of the mail server to correctly set it up.

  • charge battery for the first time and the best practices for maintaining the life of the new PC laptop battery

    Received my first laptop as a gift today (Pavilion touchsmart 15-n287cl).  You need to know 1.  How long to charge it for the first time or first several times; 2 do you need to unload and reload between each use completely and how long should it take to charge an average before being used again.  3. Since no instructions is a good idea to leave it plugged when you use all the time or the battery should be removed to improve the conservation of life?

    Thank you in advance, it has taken a lot of time to migrate from the desktop.  Want it to be a positive experience.

    Hello

    Modern batteries and chargers are now smarter than you.

    1. you can plugin and immediately to use the machine, the machine will stop charge when the battery is fully charged.

    2. No, we don't need to unload completely between uses, then as above. The recommendation is sometimes we run machine on battery until that up to 10%.

    3. when using AC is a way to protect the unit during the failure of current, all of a sudden, leaving battery on laptop.

  • Re: Satellite L750-1LU - what is the standby time battery 'common '.

    Greetings.

    I'm Rom of the Greece...
    I am a new owner of Toshiba (a few days ago) and my question is the BATTERY LIFE.
    I have a Sattelite L750-1LU and I wonna know what is the 'common' stand-by time for this laptop battery...

    When I bought the laptop (with all these countless TOSHIBA utility pre-assembled), my laptop did not stay... more... 1 HR!

    I already have a Greek contact with the technical team of Toshiba, but since they told me... the battery throughout the night the first 3 - 5 times (was... Lithium-ion battery didn't need such thing!), I wonna contacted a person non - Greek Tech.

    I already spend a few days and found a lot of interesting tips to increase the battery life, I did it, I removed the pre-installed Windows 7 with all Toshiba Utilities and I installed one pure "fresh" Win7 WITHOUT ANYTHING else (except all the drivers, I took half day... to collect) and now I think that the battery life is quite better (about 3 hours and some)...

    But I wonna know exactly what is the 'common' battery standby time, for this model, I bought.

    Please, answer me back.
    Kind regards.

    Hello

    The laptop is supported by a battery of 6 cells 4400mAh
    It is a common battery that is built in series of laptops different, and it should be possible to extend the battery up to 3,5-4 hours work.

    But be aware that the battery working time depends on notebook use.

    Various factors may change the time of working of dough: brightness of the display, for example, use of CD/DVD and HARD disk drive, the CPU and cooling performance module all of these parts would drain the battery more slowly or faster depending on the settings.

    Working with the applications Office could slower battery as a game or watch movies on DVD.

    The formula is: t = Q / I
    t = time
    Q = electric charge (Ah)
    I have = amperage (A)

    So if you want to use Notepad for example 4 hours then all laptop computer s devices should not use more than 1000mA - 1100mA in an hour.

    Hello

    If your laptop is running during the process of loading the battery if this charge will process much more time if the laptop shuts down.

    More load time when the computer is turned on is affected by the ambient temperature, the temperature of the computer and how you use the device.
    If you make heavy use of external devices battery sentence likely to be practiced at all during the operation.

    In the user manual which must be preinstalled on your laptop, I found info on the charging time:
    Battery with power on takes about 12 hours or more; power off about 3 h and more
    RTC battery with power on and with the AC pack or the battery takes about 24 hours

  • Laptop no longer charge! Battery almost empty, but is it also the faulty wiring?

    Is it possible to charge my battery now? I think my battery is completely dead now. In the past months, he stayed on less and less time without his agreement. Today, he says "battery 100%" "6 minutes". Usually, I have it just load by turning the charger cord in weird positions. I don't know if it of a faulty wiring or not. I'd rather just buy a new battery to deal with faulty wiring.

    Yes, I was making the change in your battery in the boot menu thing. I have a 625 HP and have had it for over 3 years now. Last year, I had to adjust my cable just so she can load. He stirs around a little bit when inside, but the cord/plug itself seems not loose or anything... Today, that did not work at all. I tried for several hours moving my rope to the right position for my laptop can turn on. I usually get it loads in not more than 1 minute, but today was different. Last year I replaced my load and it seemed in fact it is much easier to load. However, it is a loader rather newish and this is my battery at fault this time.

    My problem will resolve everything by getting a new battery? I can probably go to Best Buy or something. Or maybe buy one online.

    If you think that I can also be a problem with the faulty wiring, what can I do to get it fixed? I feel that this would cost me a lot. Or, do you get a new battery will solve my problem charging?

    If you think that I don't have faulty wiring, then should everyone jiggle their rope around until their laptop starts to load? It seems right that that's what I have to do just to power my laptop.

    In addition, if you think that Best Buy isn't the best place to buy a new battery (expensive as hell!), a link to a site worthy of confidence with fast delivery and the fair price would be great!

    Well, it really depends on a few things, but replace the battery and the charger is the first step to discover.  It is not too difficult to find replacements, fortunately.  Here is the battery and This is the charger .

    It could be a bad connection on the laptop itself, which would mean the jack needs replaced.  Not an impossible task, but it would have required a qualified technician to open the case to replace the power supply.

  • Can not keep the correct time on my laptop Dell M4500

    Hi all

    I, ve problem with time on my Dell M4500 laptop a few months. I tried several solutions but not worked. time holds as long as the used laptop however wake up after sleep time shows right from the start of the commissioning (sometimes for seconds, sometimes for a few minutes) and sets then went back to a wrong value. I checked the weather it is time windows or time of bios, actually, it was the time of bios that changes after getting return of mode 'sleep' and windows after the bios later time, and if I want to correct then I have to restart, go to configuration, change time bios and then continue until the next time...

    I, ve tried the following:

    battery 1-i bios modified by a new Dell... unsolved problem
    2 - Dell has provided new motherboard with a new battery (verified) and the last update of the bios > problem unsolved
    3 went to services.msc and turned on/start/stop windows.time service > problem still there
    4 enabled auto-sync > problem unsolved

    y at - it an idea about this problem? in fact I ve called Microsoft but they replied that time BIOS cannot be changed or affected through Windows because windows does not have access to the bios time, however after change of motherboard (changed with a new one) is it a physical cause for this problem?
    any help? Thank you
