Good practice for charging notebook

Gday,
I just bought new pavilion notebook and  read this on the User Manual: "The computer does not use battery power when the computer is connected to AC external power with an approved AC adapter or an optional docking/expansion device." (chapt 6 p36)
I'd like to have my notebook battery as healthy and longest live as possible, my quest is do I need to unplug the power adapter when the battery indicator shows 100% when charging while using the notebook? or just leave the power adapter plugged on AC as it is indicated on the Manual.
Many thaks,
This question was solved.

Hi,
All smart batteries and chargers are smarter than we thought. When unplug AC power, computer will use battery and at the end of the day battery needs more charging cycles.
My observations (I've mentioned many times on this forums): leaving batteries and machines 24/24 on AC at the end of two years, their batteries are much better than the ones pluged/unpluged everyday.
Hope this helps.

  • What is good practice for playing multiple video's in a single swf?

    Hello,
    I have build in the past a video wall with video's inside. After building this i came across some problems.
    If you have too many video players loading at once it takes a lot of processing and the tweens in the
    page while loading the video's where not moving fluidly, but more in a stuttering way.
    After lot's of test i found a good working solution.  I imported the flv video's into flash en exported them on the timeline
    as a embedded swf.  Then i externally loaded these swf files and that performed much better.
    Is it even good practice to load multiple video instances at once? I used this time the LoaderMax of greensock but the video's
    only play after it's completely loaded. I would like to find a way to progressive play all video's at.
    Does someone has experience with this?
    Regards,
    Chris.

    How about an XML file which supplies the title for each movie and the location or source of the video to be played?  Simple version below.
    <?xml version="1.0" ?>
    - <playlist>
    <video src="Gfx/video/Alex1.f4v" title="John Deere 330" />
    <video src="Gfx/video/Benni1.f4v" title="Hitachi Z240F" />
    <video src="Gfx/video/Scotti1.f4v" title="Hitachi Z350F" />
    <video src="Gfx/video/Scotti2.f4v" title="Hitachi Z350F" />

  • Good practice for async databinding, regarding entity-framework.

    I have some issue to find a good pattern to keep my UI responsive using asynch databinding and entity framework which is not thread-safe. It would be a shame if the UI came to totaly freeze with no feedback for a connection lost.
    So, entity framework is not thread-safe. Which mean I won't be able to rely on lazy loading here and involve than if I do async databinding to a collection of object, each object will have to load their navigations properties with their own context to display
    data. Ok, I can handle this. But what if I need more than displaying data and I want to modify a navigation property ?
    I need when I set the navigation property in my viewmodel to attach an entity from the same context than the parent entity is from. So here I have one context for multiple thread. What do I do ? =(
    Does anyone have some experience in it and can help me to clear this mess from my mind ? =D
    All the sample I can find about async databinding don't go any further than make a Thread.Sleep before returning a string, it's not realy helpfull.

    There are reasons people post simple explanations.
    One of those is because they post blog entries when they're learning something rather than when they are expert in it.  The blog post is part of their learning process.
    I sometimes share context. 
    What I do is put the context in Application.Current.Resources and then go get it from there when I need to re-use that particular one.
    xxxDomainContext DBContext = new xxxDomainContext();
    Application.Current.Resources.Add("DBContext", DBContext);
    and using that:
    context = (xxxxDomainContext)Application.Current.Resources["DBContext"];
    You can alternatively share collections in a similar way.  Depends on how many related tables you have, but reading a whole tree of static data is sometimes a good idea rather than just one table at a time.
    One technique I use is to cache slowly changing data on the client and then go get changes since the last run off the server.  For a fair few applications, yesterdays data is good enough for most data sets.  It's just the odd one or two which you really
    need up to date numbers or whatever.
    You can see a collection shared in this sample ( but the sharing is for different reasons ) :

  • Good practices for ECC 6.0 wr.t. internal tables..

    hi,
    i am told that when defining internal tables in ecc 6.0, we shud avoid using OCCURS and WITH HEADER LINE.  and always use work areas..
    is this right ? is this a good practice or a must ?
    i followed this and created an internal table without a header line .then i  am using a collect statement in my programn which fails and says that IT is not with header line !!
    COLLECT ITT.
    what to do ?
    thks

    Yes, that is correct.  SAP is pushing the use of ABAP Objects and you can not use OCCURS or HEADER LINEs in the ABAP OO context.  You should always defined explicitly and a work area.
    Data: itab type table of mara.
    Data: wa like line of itab.
    So then you must keep this in mind when doing any operations on internal tables, like in the case of the COLLECT statement, the syntax would be.
    wa-field1 = '1'.
    wa-field2 = '2'.
    Collect wa into itab.

  • Best practice for tracking database changes...?

    Dear Oracle gurus,
    I'm still relatively new to database administrating, and recently I ran into a situation which I'm not sure if there's some text-book scenario analysis or practice.
    I find it hard to track all the database changes across different servers. Our company develop software that uses the Oracle database, so we have development and test servers set up here and there, with really minimal control on them. Problem arises when we make rapid design changes to our system, which required multiple and rapid changes to the databases. I find it really hard to keep track of everything, because sometimes I can't patch some server because of people still using it for development/testing/investigation/etc.
    So, is there some kind of good practices for tracking database changes (which we even write patches for), monitoring schema modifications, or maybe even versioning database objects? I've tried to find some information but I think I did not look in the right places or ask the right questions.
    Any help is appreciated.
    Best regards,
    Peter Tung

    The first thing I would start with is:
    Find a version control system that will allow you to store files and version them (PVCS for example). You could for example, store all the sql scripts. Whenever a change is needed, the user could check the program out from the version control tool and make changes and check it back in. Besides sql scripts, you could also store binary files or any type of source code files in a version control system. This would at least put some things in order. In a version control system, you could associate a number or a string with all the files within a patch.

  • Best practice for creating DVD

    I am trying to create a DVD of the movie i just made.
    I am wondering about the exporting feature of iMovie, beucase i want to change the frame rate from 29 fps to 25 fps to give it a more movie like feel, rather then so life like....
    is is possible? What perhaps is good practice for this?
    thanks.

    29/25 fps are Apple's latest "acronyms" for NTSC/PAL...
    you change a lot more then just framerate...
    in case you like to play the resulting DVD on a NTSC player: don't do so...
    making a more "filmish" look, deinterlace your project, using
    JES Deinterlacer (free)
    .. gives much better effect...
    finally: use the cinematize effect in iM.. adding black borders give most viewers a nice ... ehm, cinema effect.

  • Best practices for package directory structure?

    I've only compiled a few java programs & while I find the language itself very easy to adapt to from C++ and Javascript, I get confused about the directory structure and classpaths & such.
    My main method of operation is to build small tools and test projects, and I would like to follow good practices for organizing my directory structure, so it will (a) work well with java, and (b) work well with my source control software.
    Let's say I am developing packages named "com.example.test.test1", "com.example.test.test2", "com.example.tools.flapper", and "com.example.tools.spinner".
    I know I can use this structure:
    /java/test/test1/com/example/test/test1/* (files for com.example.test.test1 including test1.java)
    /java/test/test2/com/example/test/test2/* (files for com.example.test.test2 including test2.java)
    /java/tools/flapper/com/example/tools/flapper/* (files for com.example.tools.flapper including flapper.java)
    /java/tools/spinner/com/example/tools/spinner/* (files for com.example.tools.spinner including spinner.java)
    But the directories seem unnecessarily deep & lead to a hassle in source control that makes it difficult to browse.
    Can I use this? and if so, how do I run "javac" and "jar" properly to compile/jar-ify each package?
    /java/com/example/test/test1/* (files for com.example.test.test1)
    /java/com/example/test/test2/* (files for com.example.test.test2)
    /java/com/example/tools/flapper/* (files for com.example.tools.flapper)
    /java/com/example/tools/spinner/* (files for com.example.tools.spinner)
    also is it recommended to leave the .class files in the same dirs as the .java files, or better to have a separate tree for compiled .class files?

    hmm, there's a lot to absorb here...
    I found these articles online that seem good:
    http://www.onjava.com/pub/a/onjava/2003/12/17/ant_bestpractices.html
    http://www.kevinboone.com/classpath.html
    I'd like to use ant if possible & understand it; I've had troubles with IDEs in the past and would like to just stick with basic build mechanisms.
    I guess as a practical example let's say I have two different applications that use the serial port, that I want to release separately, each in separate .jar files. One is called com.example.applications.serial1 and the other is com.example.applications.serial2. They both use rxtx.org's gnu.io.* libraries. Serial1 uses some packages that I have developed: com.example.tools.spinner and com.example.tools.flapper, whereas Serial2 uses com.example.tools.spinner and com.example.tools.flopper
    I think I want to organize things this way: (everything below under /java/src/)
    com
    example
    applications
    serial1
    serial1.java
    serial2
    serial2.java
    tools
    spinner
    spinner.java
    flapper
    flapper.java
    flopper
    flopper.java
    and I think I want to compile to /java/classes/:
    com
    example
    applications
    serial1
    serial1.class
    serial2
    serial2.class
    tools
    spinner
    spinner.class
    flapper
    flapper.class
    flopper
    flopper.class
    but I'm sort of lost on where to put the ant buildfiles, which directories to be in to run javac, and how to get the jar files right. From what I've searched for online, the external libraries (RXTX's jar files & .dlls for windows) are "interesting", and the easiest thing is to tell users of my .jar files to put the rxtx libs in the same library as the .jar files so I can set the Class-Path: in the .jar manifest to point to them.

  • Good li-ion (dis-)charging practices for iPhone?

    Hi There. I've been reading up on the best way to prolong the Li-ion batteries lifespan for my new iPhone 4. Any suggestions due to good experience for best practice is welcome.
    In addition, after some reading and confusion, there are two questions I already have. Which do not necessarily dictate the direction of the main question. Because these are heavily subject to different opions.
    *For my iPhone4, what is a good partial discharge percentage before charging to prolong it's battery lifespan?
    *Second, is it possible to condition li-ion batteries. Say, fully discharging the battery the first time you get your iPhone4, than after that apply the method of never fully discharging before charging. Will this condition the battery, as it is new and fresh, to be able take more stress afterwards?
    Ramhorn

    Read Apple's advice:
    http://www.apple.com/batteries/
    http://www.apple.com/batteries/iphone.html
    You can recharge li-ion batteries whenever convenient. There is no "good" time.
    Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

  • Sync with my desktop, but still connect to my notebook for Charge/Tether?

    I Sync my iPhone 4s with my desktop computer.  Can I still connect it to my Notebook with iTunes on it, and NOT have it sync?  The only reason I want to connect it is to use my Verizon Personal Hotspot tethered, and for charging.
    I don't want to connect it and screw up everything that is workinig good now, but I need to travel this weekend, and want to charge and tether.
    Is it as simple as just not opening iTunes on the notebook?

    To be clearer. I get a message saying that the machine is not authorised (although I know it is) then I choose authorise and type in the correct apple ID etc and then get a message saying that the computer is already authorised. When I click OK on that I start all over again!

  • PO for goods free of charge

    Hi frnds,
    I need to receive (import) goods free of charge i.e. i won't make vendor payment.However i need to clear the customs duties for these goods and want to take credit for CVD.When i tick free goods in ME22N the net price becomes zero.How do i clear the customs duties then ? Please reply ....
    Regards,

    Edited by: Sachin Narvekar on Jun 27, 2008 11:23 AM

    Hi,
    It is better to create a condition type by copying Base Price for e.g. PB00 as ZB00 (Statistical Price) and insert it in Import Schema. Also mark this condiiotn type as "Statistical"
    And here in Free Goods PO, do not mark "Free" indicator. Maintain Price for ZB00 (Statistical Price) and then maintain values for Custom duty and CVD conditions and proceed further.
    If you do not want to do this then, maintain 0.01 value for Base Price condition and then maintain values for Custom duty and CVD conditions and proceed further. This can also be changed during MIRO.

  • Is VHDX for data drive considered good practice on a client PC?

    Hi!
    I don't like putting user's data files (documents, etc.) inside the user's Documents directory on C:. Instead I prefer having them on a D: disk, separate from the OS. On the other hand I don't want to create a fixed size partition as I consider it a waste
    of space, especially when everything is on a rather small SSD.
    Therefore, I consider creating a virtual hard disk (VHDX) on my C: drive and making it dynamically expanding. This would allow me to store data on that "separate" disk which is actually an expanding VHDX file on C:. One problem is that for some
    unknown reason Windows 8.1 is not able to auto-attach such disks on startup, but I have seen some workarounds to auto-mount them through tasks.
    My question is the following: Is it considered good practice to put all data files on such a dynamic VHDX instead on a separate partition? Reading the VHDX explanations it looks like this file format is very stable (even in case of power loss) and is widely
    used in virtual servers. Performance should be also very good. Therefore I don't see any reason to not use it for my data drive. Or are there any drawbacks?
    Thanks in advance for any help.
    Best regards,
    Anguel

    Hi,
    Since the VHDX is created on C which should be the system partition, I don’t think it is more safety than separate partition.
    Please consider that once the system corrupted and we have to format the C to reinstall the System, it may be difficult for us to recovery the date. But the separated partition will be easily stayed without changes.
    You can try to shrink the C volume in Disk management to create a new partition.
    Just my thought.

  • Using 3gs cable for charging 4s is good ?

    hey fellas.
    i have an iphone 4s. when i use the cable which i got with the box, it doesn't work. i have to try different dimensions of jack and at some point, it starts working. and then if phone is moved, charging will be disconnected. i guess its a fault of my cable whose jack is not properly checked before sending to customer.
    now i have a cable which i got with my 3gs. i dont know its genuine apple made or not, cause i didn't purchase 3gs brand new. when i use this for charging, it goes all good. it takes only around 45 mins to charge my phone upto 100%. but the battery drains out so quicky, spends not even half day.
    when i use the genuine cable of 4s, it takes around 3 hours to charge fully, and battery goes for 1 complete day.
    suggest me if using the 3gs cable will do any harm to my battery ? and how can i check is it genuine cable or not.

    Sounds like the cable that came with your iPhone 4s is defective.  The cable that came with the 3GS should work fine.  Don't know how to tell if the cable is genuine.  It shouldn't make any difference, though.  I've used several 3rd party cables with no problems.
