iphone 5 does not charge via USB laptop in sleep

Question

iphone 5 does not charge via USB laptop in sleep

I hook my iPhone 5 up to my Lenovo G570 laptop. When the laptop is not sleeping, the iPhone charges just fine.

When the laptop sleeps, the iPhone no longer charges.

BUT.... The USB port on the laptop powers and charges other USB devices just fine, even when asleep.

ONLY the iPhone 5 stops charging when the laptop sleeps.

Anyone have any idea how to fix this?

(When I travel, its nice to be able to charge my iPhone *without* having to actually wake up the laptop)

Well, the fact is your computer must be turned on & not in sleep mode to charge your phone. Read here;

Thanks

Connect the device directly to a USB port on your computer (not an external keyboard) using the USB cable that came with the device. Your computer must be turned on and not in sleep or standby mode; otherwise, the battery may drain instead of charge.

If using a portable computer, make sure it is plugged in to power and that the display (or lid) is open. If the display is closed, the computer may go into standby, sleep, or hibernation mode and the device may not charge.

*** Unless you have a Chinese iPhone. They DO charge when laptops are asleep, apparently. Go figure.

That's weird, my iPhone 4 would always charge off my MacBook when it was in sleep mode.

I also have a Dell Precision M440, which has a BIOS option to allow it to charge devices in it's sleep.

Though that's never worked with any of my iPhones.
