My usb ports do not provide power during sleed mode.

[dkalita]

I have a problem regarding usb power during sleep mode. My laptop's usb ports stop providing power when the laptop is in sleep mode. I googled for the solution but nothing worked. Also I studied that this problem can be solved by enabling usb wake support in BIOS but to my disappointment the laptop doesn't have any such options in the BIOS setup. Note that there are no power management options in the BIOS setup.

(b) Right click Generic USB hub(s),

(c) On Power Management tab, untick "Allow th computer to turn off ....",

(d) Click OK

Hi @ banhien

Yes, I have already tried this method but nothing's working. I don't know what's the issue.

Hi,

Which devices do you need power from USB ports ? Some machines have special port or ports to use when they sleep. Your machine may not have that port and I believe Apple devices won't charge using normal USB 2.0 or 3.0 on computers when computers sleep.

I am using nokia x smartphone and it is not charging..however on a different laptop it charges when it is in sleep mode..

Also in the BIOS, there is no usb power management option or menu. So again I am left out of choices.

Is it possible that my notebook does not have chargeable ports because if it is then it seems very awkward as generally these ports should provide power in sleep mode.

Hi,

Your machine does NOT have USB charging when sleep or off port. Normally only USB ports with thunder bolt symbol support this work

Hi,
No doubt you can be true but I have another machine that has a port with a lightning bolt symbol and two other ports but it still charges from all the three ports during sleep. Whereas my notebook like you said does not have any lightning bolt symbol in any of its ports.

Anyways thanks for trying to sort it out. I really appreciate your help.
