Satellite L850: usage of AC adptor and battery at the same time?

Hi,
I have Satellite L850 and I need to know the good practice in charging the battery.
I mean by the good practice, the way by which I get the longest possible life for my laptop's battery.
Currently, I always keep my laptop connected to the charger power cord regardless its battery being completely charged or not. Does this behavior reduces the life time of the battery?
Also some of my friends advised me with strange advice, that I can to remove the battery even the computer is on when it is connected to the charger power cord! Does this safe and possible?
Please I'm waiting your help. If there is a documented answer it will be nice.
Best Regards

I do the same all the tie and now after almost two years battery on my Satellite P500 is still in good condition so I think batteries are not so sensitive.
As Akuma wrote from time to time use notebook on battery power supply only and do a complete discharge and recharge.

You can do this and use notebook without battery but I think it is not necessary.

IPad turn on wifi and 3G at the same time

If my iPad turn on the wifi and 3G at the same time, which data will my device use? The wifi or the 3G?

Ie.. At home if your in settings, wifi, connected to your home wifi....3G will not be used. As soon as you leave your house(car etc) 3G takes over until your connected to another wifi hotspot. To keep your data usage down, turn off 3G when you don't want to use it, or limit use by checking for wifi if your going to be in a location for a while.

Connecting USB and Charger at the same time

Hello guys, Is there any problem connecting usb and charger at the same time? after that, the Nokia Battery Monitor 2.0 shows 93% after full charge. Any ideia?

yes, there is a male-female usb extension cable sold on computer store.
Just pick up the length you need.
But the price is almost the same with the cheapest 2.0 usb hub (4 port), so you better consider the usb hub one.
Good Luck.

Charge ipod and listen at the same time?

hi,
i sit at my desk for about 8 hours at work and would like to charge my ipod at my computer via usb and listen at the same time. is this possible? it's a pc computer here at work. and it does not have itunes installed and i don't see having itunes on it as a possibility.
i don't like having to charge it, wait about an hour, then listen for a few hours, then charge it again.
also, do you notice any battery "leakage"? i mean, i have some battery power at night when i turn it off, (yes, i do turn it off b/c the screen goes blank) and then when i get into work and try to turn it on, i get this battery looking thing and have to charge it.
it's possible that the ipod came on while i was walking (it's in my bag), but this happens too often for me to think that it does.

You'll need iTunes if you want to access your iPod and listen through your PC. Also you'll need to set it to manual update, see the articles below.

Managing Your Songs Manually
When your iPod is in your pocket make sure you have the lock on to disable the controls otherwise it is liable to get switched on and use battery power.

Why can't I run Safari and Skype at the same time without making my computer freeze up?

I can't believe I can't run Safari and Skype at the same time without my computer freezing up, it's a MacBook Pro with Mac OS 10.6.8 and it has an Intel Core 2 Duo CPU with 2.2 Ghz and 2 Gb of RAM. Is this a hardware problem or a software problem?

I haven't gone to the trouble of actually testing to see which uses more CPU power, but Firefox has been faster than Safari on every Mac I've ever owned.
To see CPU usage by process, open the terminal (in Utilities) and enter 'top' at the command line. You might have to expand the window as processes don't appear in any logical order.
It could also be hardware-related: I have late 2009 mini with similar specs and it pinwheels easily.

Blinking green light and then orange and green at the same time...

I have an Ipod shuffle that was working good before and I don't know why I let it one month and after when I connected it to the computer Windows and Itunes didn't recognized it. It seems to function good because I can listen the songs that were before in the Ipod, and when I don't have battery I connect it to the computer and it seems to charge because after I have battery. The only thing is that when I connect it I don't listen that windows recognize it (like when I connect my USB key) and Itunes neither. Moreover there is a green light blinking two seconds and after green and orange at the same time (little lights) during one second. I can't restore it because it doesn't appear in Itunes.
Do you know what can do that???
Thx

Faites ceci:
- Retirez le Shuffle du socle
- Cliquez sur Démarrer, puis Bouton droit sur "Poste de Travail" et prenez "Gérer" puis double-cliquez sur "Services et applications", puis double-cliquez sur "Services"
-Localisez "Ipod Service", double-cliquez dessus, et cliquez sur le gros bouton "Arrêter" (Statut de Service Smile
-Rebranchez votre ipod, sur le socle.
-Sous Windows, effacez l'intégralité de son contenu. Ou alors faites un bouton droit sur l'icone du "disque" puis formattez.
-Lancez iTunes
-Ce dernier va détecter l'ipod et va vous demander son nom, avec une case en dessous "Remplir automatiquement"
-Laissez cette case validée !
-Pendant que l'ipod se remplit (il convient d'avoir des morceaux dans la bibliothèque iTunes) allez dans longlet "Réglages" de l'ipod, sous iTunes
-Cochez la case "activez l'utilisation comme disque dur"
-Cliquez sur appliquer pour valider cette option !
Vous pouvez maintenant éjecter votre ipod (ne le retirez pas du socle, cliquez sur le bouton approprié sous itunes !) et voilà, tout fonctionnera à merveille !

OK great info!
I found 2 possible ethernet to USB adapters:
By "Plugable": USB 2.0 to ethernet LAN wired network adapter - seems this will work, but I'll contact Plugable.
2. Apple USB Ethernet Adapter
Easily connect your MacBook Air computer to an Ethernet network with the Apple USB Ethernet Adapter. Small and light, it connects to the USB 2.0 port of your MacBook Air and provides an RJ-45 connector that supports 10/100BASE-T performance. BUT NOT SURE IF THIS WILL WORK ON ANYTHING BUT a MacBook Air…
One person commented:
This little gem used to be the device of choice for adding a second Ethernet interface to a Mac Mini Server and I'd been using one that way for about a year. After doing a software update to 10.6.6 it stopped working. Forewarned is forearmed – it appears that Apple is finally enforcing the MacBook Air system requirement.
Thanks for any additional comments.

How do i start video and audio at the same time in ios

How do i start video and audio at the same time in ios?
I have tried a lot of different ways but i cant figure it out?
I can get the sound and animation (timeline) to start playing.
There is no problem to start the video and the animation at the same time.
But i cant get both the video and the audio to start playing when i press a button.
It works great in OSX and on windows?
Here is an example:
// insert code for mouse click here
// Play an audio track
sym.$("_1")[0].play();
// Play a video track
sym.$("host")[0].play();
// Play the timeline at a label or specific time. For example:
// sym.play(500); or sym.play("myLabel");
sym.play("marker1");

If the game has sound in it (and possibly even if it doesn't) it may be overriding the Music app and causing it to stop playing - in which case there is nothing that you can do about it.

Recording Audio and Midi at the same time in Logic 7 Express Can it be done

I am wondering if I can record audio and midi at the same time in Logic 7 Express. I am running my guitar thrugh a Roland GR 33, and a line out and using the GR 33 to trigger sounds in the Logic's synth section but cant seem to record all three tracks at once. If any one knows how let me know. Oh and I am running the GR Synth and Guitar into the Prosonus Fire Fox and have the GR 33 out midi to the Fire Box as well. So I guss the question is how do I sent up two audo tracks and one midi track to record in real time. Thanks Victor

Try arming the audio tracks, select one of the tracks, then while holding down the shift key, select the midi track you want to record, arming the "r" on the midi track. Press "record".....

Can we use both INSERT and UPDATE at the same time in JDBC Receiver

Hi All,
I would like to know is it possible to use both INSERT and UPDATE at the same time in one interface because I have a requirement in which I have to perform both the task.
user send the file which contains both new and old record and I need to save those in MS SQL database.
If the record exist then use UPDATE otherwise use INSERT.
I looked on sdn but didn't find any blog which perform both the things at the same time.
Interface Requirement
FILE -
> PI -
> JDBC(INSERT & UPDATE)
I am thinking to use JDBC Lookup but not sure if it good to use for bulk record.
Can somebody please suggest me something or send me the link of any blog or anything to solve this problem.
Thanks,

Hi ,
          If I have understood properly the scenario properly,you are not performing insert and update together. As you posted
"If the record exist then use UPDATE otherwise use INSERT."
Thus you are performing either an insert or an update which depends on outcome of a search if the records already exist in database or not. Obviously to search the tables you need " select * from ... where ...." query. If your query returns some results you proceed with update since this means there are some old records already in database. If your query returns no rows you proceed with "insert into tablename....." since there are no old records present in database.
Now perhaps the best method to do the searching, taking a decision to insert or update, and finally insert or update operation is to be done by a stored procedure in MS SQL database. A stored procedure is a subroutine available to applications accessing a relational database system. Here the application is PI server.   If you need further help on how to write and call stored procedure in MS SQL you can look into these links
http://www.daniweb.com/web-development/databases/ms-sql/threads/146829
http://www.sqlteam.com/article/stored-procedures-parameters-inserts-and-updates
[ This part you can ignore, Since its not sure that you will face this situation
    Still you might face some problems while your scenario runs. Lets consider this scenario, after the stored procedure searches the database it found no rows. Thus you proceed with an insert operation. If your database table is being accessed by multiple applications (or users) other than yours then it is very well possible that after the search operation completed with a null result, an insert/update operation has been performed by some other application with the same primary key. Now when you are trying to insert another row with same primary key you get an error message like "duplicate entry not possible for same primary key value". Thus you need to be careful in this respect. MS SQL has a feature called "exclusive locks ". Look into these links for more details on the subject

http://www.mollerus.net/tom/blog/2008/03/using_mssqls_nolock_for_faster_queries.html
    There must be other methods to avoid this problem. But the point is you need to be sure that all access to database for insert/update operations are isolated.

Can I use a camera for application in Labview and VBAI at the same time ?

Dear all,
I'm trying to save an AVI file with Labview and make an image process with VBAI at the same time, in one machine.
The error : "Camera already in use" displayed.
My Camera is a GIGE and I work with Imaqdx. I've test the multicast mode but it only operate with several machines.
How can I do this ?
Thank's to help me,
Yoann B

I'm not necessarily saying that. It's been a while since I've used VBAI, so I don't remember all of the capabilities, but if VBAI can do the inspection and recording at the same time, you should be fine.
The trick is that only one program can access the camera at the same time. That application reserves the camera, thus making it unavailable to others.

My SB Audigy 2 card can't use headset and musicamplifier at the same time

Hi, i just bought a SB Audigy 2 [D400] and i have downloaded drivers and programs. I run Windows XP SP2.
The soundcard works fine but it is very very annoying that i physically have to change the jack in the green=line out jack from headset to musicamplifier when i want to use my musicamplifier and change back the jack in the green=line out from musicamplifier to headset when i just want to use the headset/headphones .
In the shop they told my that i can connect both amplifier and headset at the same time and then with creative software control whether there is sound in the headset or in the amplifier. But i can't simple get it work.
I tried to use the green to the amplifier and the headset/speakers in the black (line out 2) and then with creative speaker settings softeware choose headphones but still the ampliefier receive the sound and no sound in the headphones. Why? In fact no matter what configuration i try the headphones doesn't work.
But if i change the jacks so headset is in the green line out then only headset is working and the amplifier doesn't work no matter i put it in sort=line out 2 jack or orange=line out 3 jack.
Can somebody here tell me if it is possible or not to connect both headset and external amplifier and control by software which to play? and how?
please help, thx.
Michael

If you can have an ASIO compatible music playing system, then it might be possible to have system like you wish when using Creative Audigy 2 card. Since ASIO bypasses Windows Audio System, you can use both 'drivers' (ASIO - WDM/MME/DS) side by side.
Say you want to play a game (using headset /w mic) and someone other like to listen music at the same time. With ASIO capable system you can output your music for example to "center L/R (stereo) channels" and same time output sounds from other source (using MME/DS/WDM drivers) to normal output channel (Front L/R). Only thing is, you need to set your speakersystem to 4 or 6 (depending which other channel you're using) (and for better 'balance' to adjust "angle" on THX console. You get the THX console by installing Audigy 2 Zs software).
Try for example http://img332.imageshack.us/img332/463/djs9mo.jpg[/img] width="406" alt="Image Hosted by ImageShack.us" >
Another option:
Say you want to play music through external amplifier and play game online with your headset + microphone (eg. others but you listen the music, you play games)
--> try free http://img332.imageshack.us/img332/4589/tbp7rz.jpg[/img] width="406" alt="Image Hosted by ImageShack.us" >
If you use ASIO on BeatPort Player you can select L/R individually from the list(s). Same rules as described earlier.
= You can play from 2 different sources simultaoneusly (ASIO + WDM/MME/DS) to two different outputs without disturbance. The other (WDM/MME/DS) source is set 'automatically' output to (Audigy) "green" port, and the other (ASIO) to "black" or "orange" port (as set).

Ipod nano (5th generation) - want to use headphones and charge at the same time

I have an ipod nano (5th generation). Do I need a special set of headphones to use the headphone jack and charge the ipod at the same time?

The iPod nanos have a 30 pin dock connector and a headphone jack. When you charge the iPod you use the dock connector therefore you can use and charge at the same time. You cannot use and charge the iPod shuffle at the same time. You might have the two mixed up.

Problem with audio of my notebook. Audio works through pc speakers and earphones at the same time

Hi all,
thanks in advance for your advices.
I have a problem with my notebook (HP pavilion g6 2305 sl).
The problem is that when I connect my earphones the audio of my pc don't stop, hence I can hear (music, film, ...) both by earphones and speakers at the same time.
I tried to install again the latest driver audio, but nothing was changed.
I tried to use another pair of earphones, but nothing.
I have noted that if I connect the Jack at my pc, but not until the end, the audio stops from the speakers and goes through the earphones, but only if the jack is not completly inserted in the notebook.
I read a lot of forum on the web but I'm not able to find a solution for my problem.
(ps. the problem comes out suddenly, without any signal. I don't have installed any update or new software before the problem's start)

Right click on speaker icon, lower right screen.
Choose playback devices.
Select "speakers and headphones" as your default.
Disable "communications headphones".
