This has been asked before but without a definitive answer. Could someone from Acer please reply. Is it possible to turn off the "Always on" USB feature? This is when a USB mouse or other USB device is still powered by the battery even when the computer is completely powered off. If it is possible, how? If its' not possible, can this feature please be toggable in future Acer laptops or provided via a firmware update.

 

Computer is Acer S7-392, but suspect this affects several other models as well.

 

Thanks,

Alain

    See if you have any way to disable it in USB Charge manager:

    That looks very promising, thanks. I'll try that tonight and get back to the forum with the results.

    Thanks, that works. I didn't have the Acer USB Charge Manager installed on my laptop, not sure why. But, I searched Acer support and found it, installed it and ran the steps suggested. This has turned off the mouse on power down, so the result I needed.

     

    Unfortunately, there remain a number of small problems. For example:

    * if you power down, the mouse also stops drawing current (great), but if you unplug the mouse and re-plug it back in often (but confusingly not every time) the mouse starts to draw current again.

    * occasionally, if I shut down using the std Windows 8.1 "Shut Down", the PC powers down...and then automatically restarts! You then have to press the power button on the side to shut down again.

    * depending on how quickly after closing the lid you re-open the lid, the computer will either power back up normally or power up briefly then shut itself off (requiring the power button to be pressed to complete a tweo-step boot).

     

    These little niggles are annoying but not fatal. I don't know how much is a bug in the Acer hardware, the Acer BIOS or Windows 8.1 itself. My feeling is that in the next generation of Acer hardware, Acer should develop their BIOS with more functionality to override hardware and software relating to power down/up so that the user has more control over what the laptop actually does when the lid is closed, laptop shut down, lid is lifted, etc. At the moment, it appears quite random and bug-ridden.

     

    Thanks again for the good answer!
