I've just purchased a Lenovo U160 and I've not been able to solve an issue with the internal card reader. It's a "Realtek USB 2.0 Card Reader" internally wired to the motherboard.
When I got the laptop, I put a Momentus XT in it and installed Windows. I've tried using the drivers that were included on the Lenovo recovery partition, the ones on their website, and the ones direct from Realtek with no success.
The problem is, when my laptop resumes from sleep mode, I get a fair few "new USB device" noises and about the same number of "USB device not recognized" errors. If I look in the device manager when this happens, the card reader is no longer there, and I have an "Unknown Device".
After a shut down, or a reboot, it's back again.
I've tried another clean install of Windows but I'm still having the same issue (I've applied KB974476 and KB978258 before installing the drivers).
There are no sleep options in the BIOS, it's very basic. I am running out of ideas..
