Charging MacBook on the road while off/asleep

My mother is receiving a new MacBook later this week.
She already has a cheap Lenmar NVD75 cigarette lighter adaptor inverter, with the following specifications on the package:
Maximum Output Power: 75W (15 min.)
Surge Output Power: 200W (5 sec.)
Continuous Output Power: 60W
Output Frequency: 60Hz, +/- 2 Hz
Output Voltage Range: 105V - 125V AC, modified sine wave
Input Voltage Range: 11.5V - 14V DC
Here's my question:
I realize that her new MacBook is probably going to be too much for this inverter. However, I was wondering if she could recharge the MacBook on the road while the computer is either shut down or asleep.
Would that work?

Hi,
Actually the power inverter should be fine to poer the MacBook. The MacBook's power adapter is 60W, which is what the continuous power output is for that inverter. I'm sure the inverter will do fine powering or charging the MacBook while it is either on or off. Hope this helps.

I can't print wirelessly using Airport Express. I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not.

I have my HP printer connected to a USB hub, and the hub to the Airport Express, but when I select the HP from the printer list, my MacBook says the printer is "off-line" - even when it is not. I've tried several USB connectors, and several different ports on my USB hub; same result. I need to have the HP connected to the hub 'cause from there it's connected to our desktop Mac.

Droid Incredible charging more after the phone is off?

Hi I have read a lot threads regarding battery life and issues but I decided to post here since Verizon responds to these posts. Whenever I charge my phone I unplug it after the light turns green and its fully charged, after reading one of the forums I tried charging till the light turned green then I turned off the phone and to my surprise the light changed from green to orange and the phone continued on charging for another 30 minutes until it turned green. Is there a problem with the battery or the phone software recognizing fully charge too early?
I would appreciate any advice

Hi I have actually noticed a difference because before after less than an hour the battery would read close to 90% but now its taking much longer, the reason for my post is that if the light is green when the phone is on and it says fully charged why can one charge for an extra 30 min when the phone is off? does this mean that the battery is not fully charged when the phone is on?
( P.S I am getting all day worth of work from the battery and wouldnt change this phone for anything

Is there a (relatively simple) way to skip tracks with an iPod touch 5th gen using a physical button? I'm aware songs can be skipped on-screen without unlocking the iPod, but I'm looking for a method that doesn't require taking my eyes off the road.

Is there a (relatively simple) way to skip tracks with an iPod touch 5th gen using a physical button? I'm aware songs can be skipped on-screen without unlocking the iPod, but I'm looking for a method that doesn't require taking my eyes off the road while driving. For that reason, I'm also not interested in adding in headphones or additional devices that have the desired button functions. Going both forward and back would be great but I would be pleased just to have a "sight-free" way to go forward.
I've seen some mention here and there about ways to maybe change it so the volume buttons change tracks and holding the volume buttons changes the volume... but I don't know what's involved in that or if its even possible/recommended for a new 5th gen iPod. I think its a great device but its sadly lacking in music oriented functions and features... which is disappointing since music is why most people would bother getting one instead of some other "iDevice" :/

Given that you cannot do what you have asked for, perhaps you simply need to find another solution to your root problem.
Presumably, you want to skip to the next track because you don't want to hear the current one, and that is because...
You don't like it.
You've heard it recently and don't want to hear it now.
Simply don't want to hear it at this time.
For problem number 1. Don't put it on the iPod in the first place. (I know, obvious answer!)
For problem number 2. How about playing from a Smart Playlist (initially created in your iTunes Library) which has only songs you've not played recently?
For problem number 3. Hhhmmm! Create alternative Playlists for use in the car.
As for going back to the start of the "now playing" track.... Well, if your Playlist has only songs that you really, really want to hear, then you'll be looking forward to that rather go back to the beginning of the current song.
I'm not trying to be prescriptive, just giving you food for thought.
(They are all cheaper options than buying a car which can control the iPod from the steering wheel.)

Here is apple's instructions in calibrating the battery KB Article
As for leaving it plugged in, that's the normal process most people do, there is circuitry in the computer to ensure the battery does not get over charged. Aside from calibrating it, I'd avoid any deep cycles, that is draining it completely, you're better off plugging it in when you have the opportunity and not wait until the battery is nearly drained. Deep cycles can shorten the life span of the battery.

Keep MacBook on adapter when powered off?

We've had my daughter's new Macbook for about 6 days now. We've never owned a laptop before and right now it's still getting minimal use. When we brought it home, we charged it up and for the most part, it has rarely left the house. We put it to sleep if it's not being used for a couple of hours, but if we know it won't be used for most of the day, we just shut it down. It's also shut down overnight.
Whenever it's home we have it connected to AC power so as not to use the battery if we don't need to. It's "plugged in" whether it's powered on or not. But as I read some of these threads, I'm becoming confused as to whether that's such a good idea. When we bought it, the lady at the Apple Store said something like "it's not like a cell phone where you have to run it down before you recharge it. Just plug it in unless you need to use it as a portable."
As I said, we're brand new to the portable thing, although we've had Macs for years. I'd like to start off on the right foot with this thing, so we get as much life out of it as possible.
Any thoughts?

Hi formerly Don,
You'll find some basic useful info on this at http://www.apple.com/batteries/notebooks.html and http://www.apple.com/batteries/
http://docs.info.apple.com/article.html?artnum=86284 is worth reading , too.
You will find more comprehensive information , though, at http://www.batteryuniversity.com/parttwo-34.htm
Generally its not a good idea to keep a Lithium Ion or Lithium Polymer battery on the charger continuously, though the ideal" trade off depends quite a bit on your general usage pattersn, whether you are storing the computer for a prolonged period of time, etc etc.
Cheers
Rod

Leave the charger on all the time?

Is it wise to leave the charger on during the night while I'm not using the mac? Should I unplug the charger and get it back on the next day.
I take the Mac to school and don't use the charger while I'm there.

Macbook Pro retina display 13 inch stopped charging. Charger LED also not on while plugged in. The battery fully drained off but the system can detect the charger when it was switched on.

Macbook Pro retina display 13 inch 2014 model stopped charging. Charger LED also not on while plugged in. The battery fully drained off so the system can not be started but the system can detect the charger when earlier it was switched on before draining off the charge. Charger type magsafe 60W.

Once you have examined the power inlet on the computer for dirt, and made certain that the pins on the end of the MagSafe cord are free to move in and out to make contact, there is very little you can do yourself.
You will need to visit your Apple Store (FREE with appointment) or your Apple-Authorized Service Provider (policy varies). They work on these all the time and have good expertise and lots of spare parts to try to determine the problem.

I'm using a macbook pro 2011 15",while i was charging it,i accidentally switched off the power supply while it is half way charging,will the battery get damaged if charging got interupted and switched on and off?

Macbook pro shuts off as soon as charger is disconnected. Will only charge with older square tip charger and not the newer "L" magsafe charger it originally came with.

I have a 2011 macbook pro. I recently spilled some water on top of the macbook while it was off and charging (closed). Some water got to the charging port so I immediately disconnected the charger. Right away I brought it to ibreakufix and they looked through and told me there were no issues. I plugged it back into the charger to see if it would turn on and the "L" shaped magsafe charger it came with would not light up or charge the MB and it would not turn on. At the store, the person showed that it turned on using the older square tip charger. I went to apple thinking the charger was bad but that was not the case, tried a new charger (L) and still did not work. I came home and plugged in my older macbook charger (square tip) and it worked fine as it did at the shop but as soon as I unplug the charger, the MB shuts off. I took off the bottom and switched the battery with my other macbook thinking the battery might have shorted out but it still shut off. Battery display indicates that it is charging and in fact charged up to 100% but as soon as charger is disconnected it shuts off. Oddly when I plug in the newer "L" charger and disconnect the battery from the macbook, the charger lights up and powers on the MB. Any thoughts?

Hello Arhim22,
Welcome to the Apple Support Communities!
In this situation, because of the liquid spill, it may be necessary to have your MacBook Pro evaluated for service. For more information on this process, please refer to the attached web link.

Charging iPhone 3G While Computer is Off/Asleep/Standing By

I recently purchased an iPhone 3G and its dock, but it turned out that I cannot charge the iPhone via USB while my computer is off, asleep, or standing by even though the dock is connected to a third party's AC-powered USB hub, which enables me to charge my iPod nano (1st gen.) in the same situations.
I know I can charge the iPhone anytime if I use the Power Adaptor came along in the package. However, switching between the connection to the USB hub for syncing and charging, and to the Power Adaptor just for charging when I don't use my computer is kinda troublesome for me. I mean it would be great if I could keep the iPhone on the dock for charging regardless of my computer's status.
Does anyone know any AC-powered USB hubs with that capability?

Yeah, wouldn't it be nice to just walk in the door and pop the iPhone into a dock and know that you'll have a functioning phone in the morning? I've tried a few things to no avail. Allow me to list:
-USB hub connected to computer only works when the computer is on
-USB hub on AC only - nothing
-USB hub on AC and connected to computer only works when the computer is on
-USB hub connected to iPhone's AC adapter - nothing
-USB hub connected to it's own AC and iPhone's AC - nothing
-USB "Y" cable works when the data/power end is plugged into an awake computer or the iPhone's AC adapter
-USB "Y" does not work across the power only end at all no matter what I've plugged it into
-The Wii and Tivo will charge the iPhone straight up as will a USB battery I have
-Tried my leftover Xbox 360 HDDVD drive for fun and no charge (I didn't hook the drive to my computer, just plugged it into the wall)
All I can guess is that the iPhone needs some sort of phantom data signal from an awake computer source or it's AC adapter. I want to try a USB A/B switch. If it weren't so costly I would try a wireless USB hub to see if it provides that phantom data at all times since it isn't connected to a computer at all (or possibly the opposite being true that it will never sync since it isn't connected).
Talk about annoying. If there was a true "Y" USB cable than theoretically I could plug one end into the wall and one to the PC.

Does the battery charging in the macbook pro retina automatically cut off when the battery is fully charged?

Does the battery charging in the macbook pro retina automatically cut off when the battery is fully charged? or does it continue charging?In which case,is it better for the battery life to switch off the power supply or leave it on while using the macbook?

Yes, and the pilot light on the MagSafe2 connector changes from orange to green. If you unplug, you will start draining the battery again, whereas if plugged the Mac will take power from the brick and leave the battery in a charged state.

I forget to charge my MacBook Pro and it turns off because of that. Now it wont automatically connect to saved networks. I have to put in manually to make it work. Even after restating still the same. Sometimes pulling the Battery out fixes it

I like to watch tvcatchup or sky go or I player on my iPad while falling asleep, the problem is that the iPad then stays on all night. I would like to find an app that allows me to set a timer for the iPad to switch itself off automatically.

Does such an app exist? Can anyone help me? Thanks

You can try the Sleep Timer.
