Can I always operate my MacBook while plugged into an electrical outlet, does this hurt the battery?

Doing so does not hurt the battery. When remaining connected to a power source after the battery is fully charged, charging stops.
It is recommended to go through one complete charge cycle at least once a month.

Is it advisable to use your i Pad plugged into an electrical outlet rather than the Battery in use?

Is it advisable to use your iPad plugged into and electrical outlet rather than using the battery all the time?

I use my iPad while it is plugged in and I use it on battery power as well.
I use my iPad all day long at work on battery power and then come home and plug it to recharge. Typically I will use it the rest of the night while its plugged in. When the battery is fully charged, the charging process stops and you can continue to use it while it is plugged in and it will not overcharge.
It will not hurt to use it while it is plugged in, but the beauty of having a better powered device is that it is mobile and you don't have to plug it in to be able to use it virtually all day long.

MIFI4620LE Jetpack blinking amber light--does this mean the battery is bad? Should the unit operate without the battery installed if plugged in?

MIFI4620LE Jetpack blinking amber light--does this mean the battery is bad? Should the unit operate without the battery installed if plugged in?

The MIFI4620LE Jetpack does not work without a battery installed, even when connected to an external power supply.
I personally think that was a dumb design. I would think the unit would use more electricity when continually charging the battery than just powering the unit it's self, but that's the way Novatel made them.
If your Jetpack works with the battery installed and connected to an external power supply, but does not power on with power supply disconnected, I would say that the battery is defective or worn out.
You should be able to go to a nearby Verizon Store and have them either test the battery or put a new one in it to see if it works. Then you will know if you need to spend the $$ for a new battery. OR if you always use your Jetpack at home, or in your car, just use the old battery connect to a power supply or your cigarette lighter and save the cash.
As the Customer Support person stated, the slow blinking amber light is a normal state when the Jetpack is turned on and connected to Verizon's service.
I hope this solves your problem.

PRESARIO C700 SAYS 'PLUGGED IN AND CHARGING' BUT DOES NOT CHARGE THE BATTERY

I have a Compaq Presario C700 (3 actually), one of the 3 has a problem and only works when on battery power although it is plugged in and states it is charging? I know the batteries are ok and the AC as they both work fine on my other 2 systems. The laptop will not work off mains alone and has to have the battery connected. Any ideas before it goes to the computer grave yard?

Hi Builderboy,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your Compaq Presario C700 Notebook and having an issue with the battery. Here is a link to test and calibrate the battery.
Hope this helps.

I have new mac pro, does it hurt the battery, leaving computer plug in

My computer is about month old. I am new working on a mac computer

I found my answer, reading other posts. Thanks

Does it harm the battery if the macbook stays turned off for a few months?

I might be in a situation where I will not use my macbook for a few months. A family member may use it occasionally, but it would be turned off most of the time. Does this hurt the battery or other aspects of computer performance?

From the User Manual: "Storing your MacBook If you are going to store your MacBook for an extended period of time, keep it in a cool location (ideally, 71° F or 22° C) and discharge the battery to 50 percent. When storing your computer for longer than five months, discharge the battery to approximately 50 percent and then remove it from your MacBook. To maintain the capacity of the battery, recharge the battery to 50 percent every six months or so."

IPad is discharging while plugged into wall outlet

I cannot find any information on this issue, so, I am hoping someone can steer me in the right direction.
My iPad (retina) has begun discharging while plugged into a wall outlet using the provided power brick and USB chord. If I turn it off, it will charge up and then slowly discharge when in use--of course, that makes sense. However, what it is doing now is the following:
1. I plug it into the wall outlet using the USB chord and brick
2. I begin using the iPad under continuous power
3. It shows a power hookup (the lighting bolt to the right of the battery icon)
4. It drains the battery. In the time it has taken me to type this discussion, the battery indicator has dropped 1%
What gives? Is my iPad defective?
Any help is appreciated.

Perform a "reset" on the device by pressing down and holding the home button and the sleep/wake button for up to 30secs. until you see a black screen with the Apple logo, then release.
Then test to see if it solved the problem.

Can I use my iPad Mini while plugged in thus keeping the battery at 100%?

Can I use my iPad Mini while plugged in thus keeping the battery at 100%?
Or must I use it on battery all the time?

Copied from Texas Mac Man ...
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

My macbook battery will not charge. I have tried unplugging and doing an SMC reset but it did not seem to change. I have yet to try another magsafe charger. The charger has a dim green light while plugged into the computer. What are my next steps?

Hello Everyone,
This is my first time using the forum. My macbook battery will not charge. I have tried unplugging and doing an SMC reset but it did not seem to change. I have yet to try another magsafe charger. The charger has a dim green light while plugged into the computer. What should my next steps be, besides trying a new charger as well as being the most cost effective?
Thanks

Hi ..
The battery may need replacing.
Check the battery maximum cycle count > Mac notebooks: Determining battery cycle count
And check the adapter > Apple Portables: Troubleshooting MagSafe adapters

If I always have my MB Pro plugged into the power adapter. . . .

If I always have my MB Pro plugged into the power adapter, will my battery still wear out as it would if I were depleting and recharging it daily?
I tend to find a power outlet anywhere that I go in order to run my MB Pro on the adapter rather than using battery power. It's a habit that formed while using my 6 year old Powerbook G4 with about 5 minutes of battery life per full charge.
I understand that it shouldn't wear out to the same extent as running the battery down constantly, but is there still a significant effect?
Does the adapter bypass a full battery and power the computer directly?
I feel like an idiot asking this question, but I am really curious.
Thanks in advance for your responses.

If I buy Lion in the app store, can I ''reset'' my whole macbook (instead of doing this with the cd that comes with the macbook)?

If I buy Lion in the app store, can I ''reset'' my whole macbook (instead of doing this with the cd that comes with the macbook)?
With ''reset'' I mean, repair because it is from 2007 and so slow. So that all the data and programmes are gone and I can start over with Lion!?

You have a choice. You can start by erasing the drive and reinstalling Snow Leopard prior to purchasing and downloading the Lion installer. Or you can purchase and download the installer, save the Lion installer, create a bootable Lion USB flash drive installer, boot from the Lion installer, erase the hard drive, and install Lion. I would suggest the second choice:
Make Your Own Lion Installer
1. After downloading Lion you must first save the Install Mac OS X Lion application. After Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button or quit the installer. You must do this because the installer deletes itself automatically when it finishes installing Lion.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to several hours depending upon the drive size.
3. Locate the saved Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the InstallESD.dmg disc image to the flash drive as follows:
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the InstallESD.dmg disc image file into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable Lion installer that you can use without having to re-download Lion.
To install Lion from scratch:
Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot From Lion USB Flash Drive:
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the USB flash drive then click on the arrow button below the icon.
Erase the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.

IPod only works while plugged into computer!

Help! My 2Gb iPod nano went through the washing machine, and after a few days of drying out, it only works while plugged into the computer. As soon as I take it out, the screen goes blank. I can access all my music, podcasts and photos while it's plugged in. I have tried the 5 Rs to no avail. Anybody have any ideas?

I also sent my nano through the wash and I found that if you get an ac adapter and plug it in for a few hours you will have battery life. This made me very happy however I have noticed that I can not turn the ipod off unless the hold button is on. Battery life is also not as long but long enough for me. Hope this helps

Have my MacBook Pro plugged into a monitor and also using a wireless keyboard. I want to close the MacBook but every time I do the monitor turns off - is there a way to avoid this?

Press any key on the wireless keyboard after you close the MBP and it goes to sleep. The computer will wake up with the external monitor as its display. This is called Clamshell mode.
