USB power while in sleep

My MBP running OSX.4.11, is there anyway to make the USB power to keep running while the MBP is in sleep? Thanks

No, there is not. You might consider a powered USB hub.

  • How to keep USB powered while in sleep

    I've read about people wanting to turn off USB power while in sleep mode. I would like to know how to turn it on so I can charge USB-powered devices without having the system on. I would prefer it to only work while plugged in to A/C power, but won't mind if it's all the time.
    No power option under system settings, only "energy saver" and nothing there controlling USB power.

    When the system goes to sleep, the I/O controller turns off all outputs. The system has to be on in order for you to power your USB devices.

  • Selective USB power while Mac Pro sleeps

    My Mac Pro seems to power all USB ports during sleep. I would like to selectively power some ports and not others. For example, I have a utility USB light on the back of the MAC Pro and a CwLinux LCD screen on the front which I would like to see turn off whenever the Mac sleeps (The USB power controller gets hot if these stay on for long periods without airflow).
    Any thing in Leopard that would control this behavior?
    Thanks!

    There is no provided mechanism to selectively control power to the USB or Firewire ports. Normally USB ports shut off when the computer is asleep unless you connect a device the prevents the port from shutting down, which you obviously have. You will just need to get used to disconnecting them when not in use if they don't have power switches.

  • Charging phone using USB ports while in sleep

    Hey guys!
    I recently updated my macbook pro mid 2011 to the new operating system: MAVERICKS
    I used to do this little handy thing, where i used my mac as a powerbank for my phone once it was empty. I would insert a micro usb cable in one of the usb ports, and it would be active and thus charge my phone....
    It worked before, but in mavericks it's gone!
    Now it seems like in mavericks the usb-ports aren't powered during sleepmode anymore... how do i change this back?
    Thanks in advance!

    I run Mavericks, my USB ports charge my iPad and / or iPhone while asleep. The behaviour has not changed.

  • Usb power off while sleep, let active speakers go in standby mode

    is there a way to shut down power to the usb out while the mini sleeps, so my Kef X300a speakers will go to standby mode?
    or is there an alternative way regarding the x300a speakers.

    sudo pmset -a hibernate mode 25  , did the trick, usb powers down in hibernation mode, still able te awake the mini with bluetooth mice and keybord.

  • USB has no power when computer sleeps

    When my computer goes into sleep mode, time machine cannot connect to my external HD because apparently the usb port goes to sleep along with the computer. Same thing happens when i plug my iphone to charge. I plug in my iphone, shows that it's charging, I put the computer to sleep, it stops charging instantly. I have two imac computers, same thing happens on both machines. Is there anyway to keep the power to the usb ports while the computer sleeps?

    Hi there, Welcome to the Apple Support Forums. What I say is just my own opinion. We all work in many different ways.
    I can't see any benefit to keeping a USB port fired up to keep a hard drive running, when the computer and Time Machine are both asleep. If nothing is happening or changing on your computer then there's not much point of keeping a Time Machine drive running. In addition, I wouldn't consider using a USB powered drive for something important like a backup system. USB powered devices can be pretty flakey.
    Meanwhile, as far as a charger for an iPhone, this year at MacWorld SF, I bought a Griffin Simplifi dock. It also doubles as a memory card reader, and has two USB ports for thumb drives or whatever. It's got it's own AC power adapter so I don't worry about the computer going to sleep or even shutting it down.
    Amazon has the Simplify device for $42 w/free shipping. I leave my iPhone in the dock whenever I'm around the office. I think I paid around $70 at the show and don't regret it a bit.
    Apple also provided you with a small square AC power adapter for a USB cable to connect to charge your iPhone (at least they did with mine). But I really like having the dock sitting just in front of my Mac.

  • Leopard 10.5.6 Causes Apple Keyboard USB Devices to Lose Power While Asleep

    My Apple keyboard's left usb port does not supply power to any device connected while my mac is sleeping. I have my iphone connected there to charge at night while the machine is sleeping --to save power. Before updating to 10.5.6 this was not an issue. This problem has been noted by others, but I have not yet seen a proper solution. Can anyone help?

    Just want to add my name to the list. This is exactly the same thing I've experienced with my iPod Touch 2nd gen. I started noticing the battery was half gone when I left it plugged into my keyboard USB port while the iMac was in standby mode. It was always fully charged +before the 10.5.6 update+. I've now had to remember to disconnect every time my iMac enters sleep mode. Which is, of course, annoying.

  • USB Power on sleep mode

    Do MacBook Pro's supply power to USB devices while it is in sleep mode unplugged?

    Thanks. So if it is supposed to work for iDevices, why does my iPhone 4 not charge while in sleep mode?

  • How can I keep USB's ports active while in sleep mode?

    How can I keep USB's ports active while in sleep mode?

    OK, for some of you that may have the same problem or question as me. I have been testing my MAC Book Pro for ways to continue to power the usb while laptop in standby or off. I have found the following thing to work or not work.
    1. The laptop doesn't send any power to your USB's when it is powered off reguardless if it is plugged in or not.
    2. If laptop is put in standby no power is sent to USB's unless the power cord is plugged in on the laptop. So once again if you plug your laptop in and then put it in standby it does still send power to the USB's when requested.
    So the bottom line is, On my last laptop (toshiba) I was given an option to go into system preference and make a change that allowed my laptop to continue to send power to USB's when requested while in standby or powered off. I was hoping I could do the same thing with my new smokin Mac Book Pro but I haven't found that kind of option in the MAC.

  • USB charge while sleeping

    Hey,
    I notice in an add from Toshiba that their notebooks can now charge cell phones while the notebook is in sleep mode, and possibly even while turned off.  Would there be any way for a DV6-2064ca to be able to do something similar?  I sync my smartphone to my notebook while I'm home, but until I can figure out how to shut off the lid light, I'm putting the notebook into sleep mode over night and it doesn't charge my phone.\
    If it will be in a future BIOS update, that'd be cool, I can wait...

    My old Acer AspireOne running XP will charge devices in standby mode on battery power, but not my new HP Mini for some reason in sleep mode on battery power.
    If I connect the Mini to the wall AC adapter and then put it into sleep it will charge the usb connected devices, but not if I put it to sleep while only on batter power. Here's the kicker. If I unplug the AC wall adapter after putting the computer to sleep; it will still charge my devices. This shows there isn't anything wrong with the hardware to make it unable to charge in standby there just isn't any setting to do so. 
    I've clicked on the only two setting I can to make it send power while on battery sleep, but it refuses to send power to the usb on battery. Disabling the computers ability to turn off the usb to save power in the power settings and in the device manager to not allow it there either but nothing works. 
    I'm SERIOUSLY considering taking this thing back on this soul issue since I only bought it a few days ago. I ride my bicycle to different states, and it is very important that I can charge my iPod to have my maps with me so I don't get lost. 

  • USB Power during sleep

    I'd love to be able to power/charge my Ipod(s) while the lid is closed and asleep. Is there a firmware hack to keep USB powered while sleeping perhaps?

    Hi Ken,
    when your powerbook or ibook is in sleeping mode, the USB ports are switched off and are not charging. If you have a FW to iPod cable, this will provide power for charging even if the computer is in sleep mode. This is even so when like with the newer iPods FW cables cannot be used for data transfer. I have just tested this myself using my powerbook and my 5th generation iPod.
    Also, you can always check whether your iPod is being charged yourself, by watching the display! If there is this electrical spark symbol visible on top of the battery icon, then it is being charged!

  • Macbook Pro 13" late 2011 crashes when i plug out a "Focusrite Saffire 6 USB" while in sleeping mode.

    Hi Forum,
    I have a problem with my Macbook Pro crashing when i plug out my "Focusrite Saffire 6 USB" while it´s still in sleep mode.
    I do have the latest drivers and updates so is there any way to fix that Problem ( besides not pluging it out while in sleep mode)?

    Man punches himself in the nose. "OW!" he says. He punches himself again. "OW!!" he says. After the sixth or seventh time, he asks a friend how he can stop his nose from hurting.
    "Stop punching yourself in the nose," the friend advises.

    The power light will slowly flash on and off when the Officejet Pro 8600 Plus is in a sleep mode state.

  • Which USB 2 port charges iPod while iMac sleeps?

    I've tried them all, and once the iMac is asleep, the light goes off on the iPod shuffle. (2nd Gen.) iMac is a new one. Thanks.

    All three USB ports on my white 20" C2D remain powered during sleep;
    I just checked them with the power lamp on a USB-powered audio box.
    I'd think that would have to be true of all Macs -- if USB power was
    off during sleep, HOW could the USB keyboard signal the computer
    to wake up?
    WRT the iPod, are you sure the light is a power indicator, rather than an
    activity indicator? Maybe the iMac "unmounts" the iPod before sleeping.

  • Can I save $ while integrating my IPhone? Can I use my BB USB Power Adaptor

    I'm extremely happy with my IPhone (3G-16)... but for anyone who doesn't own a lot of Apple stock, or oil futures, times are tight.
    I need a second USB power adapter. Can I simply plug my IPhone USB cable into one of the myriad of plugs which I have without killing my IPhone?
    I've got one from my blackberry days which takes in 100-240V and outputs DC +5.0V---0.5A.
    Apple doesn't list the specs for their power adaptor online, at least not where I can find them.
    My other options are an ac plug to USB which came with my Garmin bike computer and a car charging unit for the Blackberry.
    How concerned should I be about the different levels of power which may come out of plugs from different chinese factories, and is there a place where I can learn what the IPhone needs?

    Using any other type of charger would void your warranty if it damaged the iPhone.
    You can just charge the iPhone while it's plugged into the USB on the computer. No need to have an extra adapter.
