I am not sure whether this is a Windows Issue or not, it could be driver related, but I am leaning against that.
I have just purchased two laptops that are the same in every respect except the color of their cases. Here is the Speccy system snapshot.
I am having a peculiar problem with the SD card reader and the USB 2.0 ports: if the computer sleeps (at least for any period of time) these devices "vanish" from Device Manager. If I open Device Manager and hit the "Scan for hardware changes" button they always come back upon completion of the scan. I think the same is happening for Bluetooth as well, but I haven't needed to use it enough yet to be certain of that. It seems to me that the Bluetooth device icon shows up again during the hardware scan, but I'm not 100% positive.
I seem to recall, in multiple versions of Windows, that certain devices can go through this "vanishing act" either secondary to sleep settings or power settings, but not at the "top level" for either.
If any of this seems familiar to anyone, would you kindly point me to the system settings I need to change to rid myself of this vanishing act?
