Charging via USB does Mac need to be out of sleep

When I charge via USB I think I read in the manual that the Mac needs not to be in sleep mode for it to charge - is that right? I have my Mac set for sleep at 30 minutes, although this often doesn't work anyway but am in the habit of just hitting a Quickeys key to sleep the computer. I want to make sure I'm charging right so I get the best life out of the batter that's possible.

Yes, that's correct. In sleep mode the USB ports are not powered.

Will iPod Charge via USB without.....

Will iPod charge via USB without the computer being on? It was a question I had because if the computer does not need to on... then I can plug it into any computer that has a USB port. I would like to know if the computer is needed to be on... because to be honest, I don't want have to turn on my computer everytime to just charge my iPod.
Right now I am using an old adapter from my previous iPod to charge it... but the problem is me, my mom, and my bro all need to share that charger and tonight, my brother needed the cable to transfer more music but he couldn't because I was using the cable... :-\

Ok... Um... I had an old iPod with the buttons still... not on the click wheel. Back then they came with chargers... so I just use the cord and charger that came with that. But when I got my new 5G I gave my old iPod to my bro... and thats his cord he needs to use for his iPod... to transfer music and what not. I should just buy a new adapter that compatible with the USB Cord, that way me and mom just use that since she has a nano... and my bro can just keep his cord.
Thanks for your response.

IPad won't charge using power adapter but will charge via USB

I have an iPad 1 that recently stopped charging using the power adapter. "Broken power adapter or cable" I thought and reached for a spare that I have. That didn't work either. The original power adapter however DID charge another iPad without any problems, so the problem cannot be with the adapter or cable.
Now this is the wierd bit - using the original cable plugged into my laptop I get the usual "Not charging" message but the iPad DOES charge slowly this way.
I rebooted the iPad, restarted it in recovery mode and restored the firmware, cleaned out the 30-pin connector port - all those useful bits of advice that you find on the internet but all to no avail. The iPad just will not charge using any of the many original Apple iPad charger sthat I have been able to get my hands on but will only charge on an underpowered USB port!
The 30-pin connector must work otherwise it wouldn't charge via USB. Can there be some kind of wierd internal hardware defect that might cause such behavior?
I fear that if I take a 3 year old iPad to the Apple Store they might just give me their best smile and show me the latest iPads but this old iPad works fine otherwise and I don't really want to replace it.
Anyone got any ideas?

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
And this - Unplug the charger from the iPad and then replug. May resume charging.
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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 (2.5W, 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.

5G Video iPOD stopped charging via USB: can someone help?

I bought 5G video iPOD last month. After about a month of charging via USB 2.0 port on WinXP desktop, iPOD no longer charges with USB port. If I connect it to desktop, it syncs songs and shows its charging but in fact it does not charge. As it can't sleep, its loosing power. If I hook it up in the night, its discharged in the morning.
I tried to charge it in the car (with car charger), iPOD charges fine. I have tried to change ports, tried different computer (laptop) and also sent iPOD for service, NOTHING HELPS!
I sent it for repair to Apple, but i got it back in 1 week saying its is perfect condition and no other details. (Very disappointed with Apple's lack of service)
Right now, I am stuck with iPOD not charging with any USB port. How do I solve this? Can the usb ports suddenly become low powered from high powered? Please advice.

I am trying to connect a Windows 7 / 64 bit to an Epson printer on my Mac. The printer is hooked into the Mac via USB; the Mac is networked to a Linksys wireless router with an ethernet cable, as is the Windows box. Any tips on how to do this?

I am trying to connect a Windows 7 / 64 bit to an Epson printer on my Mac. The printer is hooked into the Mac via USB; the Mac is networked to a Linksys wireless router with an ethernet cable, as is the Windows box. I installed the current Bonjour printer services software on the Windows machine, and separately installed the driver software for the Epson printer on the WIndows machine. Running the bonjour wizard, I get an alert saying 'I don't have sufficient access to my computer to connect to the selected printer'.
The printer has 'sharing' turned on from the Mac end; this works with a Powerbook via the wireless connection. Sharing is also turned on in the Windows printer control panel for this printer (under properties). The Mac is a G5 running 10.5.8. When I try to print a page from the Windows machine it gets hung in the print queue.
Any advice how to proceed would be appreciated!
thx,

Am considering buying a Time Capsule. But all specs I read about it (re: printing) is how to hook up a printer via USB connection. Need to confirm...that a wireless printer will work with the router feature of the Time Capsule. I assume yes...?

A wireless printer connects to the network just like your computer, or iPhone/iPad, etc. connects using wireless.
The printer must be set up intially to scan to "find" available wireless networks, then your specific wireless network needs to be selected. Then the password for the network needs to be entered.
Once the printer is configured to join the network, it is always connected to the network. No further configuration is required.

Phone only charging via usb

Hi,
I have a problem with my blackberry. A couple of weeks ago it stopped charging via wall socket charger. After trying a couple of different chargers and still not charging I contacted my service provider who brought it in for repair. After about a week I received the phone back from repair. They did not repair the phone because they said it would be a chargeable repair. I asked them what the fault was and they said the charging port on the phone had water damage but I can't see how because it has been no where near water. I tried the phone again with different chargers but still would not charge. I then tried a usb charger via pc and the phone now charges with no problems. So now I'm charging the phone with a plug in socket with usb connection. I Phoned my service provider to say the phone is charging via usb and the phone must have a hardware fault, But they are still saying that the phone is damaged and it is a chargeable repair. I can't see how if it is charging normally via a usb. Please can you confirm if the phone would have a hardware problem.
Thanks

Hi and Welcome to the Community...apologies for the delayed reply...hopefully you already have this sorted, but just in case!
As described, this sounds quite odd indeed. I would not expect behavior in the manner you describe it. But, since this is a user-to-user community and not a formal communication channel with RIM, all I can give you is my opinion based solely on what you have said. Nevertheless, at an internet distance, it would be impossible to contradict what your warranty service provider has told you, even if I find the situation to be quite strange from your description.
Good luck!

Ipad 2 not charging via USB after IOS 7 update

I have recently update my i Pad 2 to IOS 7.
The update has completed sucessfully with no issues but I have now found that the iPad nolonger charges via USB. When plugging in the 30 pin cable the chargin icon flashes and then switches to not charging. If I plug in the AC charger it all works fine.
The cable that I am using is the original cable, I have read in the forums that there is some issues with IOS 7 and uncertified cables. Is the original Apple 30 pin connector uncertified ?
Thanks in advance.

Normally, they don't. There are some out there that do have enough power to charge a full sized iPad.
It is very possible that whatever they did to the firmware to make it detect different cables could have affected how it charges. I know prior to 2011 the ipad used to send more power to the port which allowed people to plug in keyboards etc, but a 2011 update changed that, so it's not unprecedented.
Have you tried to give your iPad a reset? Sometimes if that port has issues it 'turnes off' and it takes a reset to turn it back on. Hold down the sleep and home keys until it reboots. Try again and see if that helps.
Other than that, if Apple has decided to change the configuration there's not much users can do but alter their behavior to fit in with what the device allows.

WHEN I USED TO CONNECT INTERNET FROM MY IPHONE 4S PERSONAL HOTSPOT VIA USB, AN ICON IN THE NETWORK PREFERENCE NAMED "IPHONE" GETS OPENED.... BUT NOW THIS IS NOT HAPPENING AND I AM NOT ABLE TO CONNECCT PERSONAL HOTSPOT VIA USB CABLE. PLEASE HELP ME OUT

WHEN I USED TO CONNECT INTERNET FROM MY IPHONE 4S PERSONAL HOTSPOT VIA USB, AN ICON IN THE NETWORK PREFERENCE NAMED "IPHONE" APPEARS.... BUT NOW THIS IS NOT HAPPENING AND I AM NOT ABLE TO CONNECT PERSONAL HOTSPOT VIA USB CABLE. PLEASE HELP ME OUT???

Please don't shout! Using all uppercase means shouting on the internet. If your keyboard is stuck please say so, otherwise people will think you are being obnoxious.
Now the first question is, when you are saying connecting to personal hotspot, have you always been using the iPhone to connect to the internet? Are you someplace where the only place to connect is available via tethering to the iPhone's celluar network? Or do you have other options?

E75 does get charged via USB if attached to PC

Hi,
I upgraded the E75s firmware to 110.48.125, now when I connect the phone via USB cable to my PC it does not get charged, earlier it used to get charged via the USB cable. Are there any settings that needs to be changed or has Nokia removed this feature in the current firmware?
Thanks in advance.
Anish

Yep - same error messages - looks like it can't find drivers but when I try and get it to search for them on installation disk it says it can't find anything more appropriate than current settings (which btw says does not need any drivers !).
Great so a few of us have the same issue. Does anyone have an answer ? Is there anyway of getting these questions to Apple or did they cut their support costs by replacing tech support with discussion groups.
