No Sleep Option in Windows 7

I worked around the issue by burning the data to a DVD, but my original issue isn't solved: I rebooted into Windows and ran the installer from the DVD. It gave me the option of Repairing or Removing Boot Camp (which our IT dept already had installed). I chose Repair. After the installer ran and I rebooted, no 2880 x 1800 resolution had been added to the display control panel (highest res still only 1600 x 1200, which of course is the wrong aspect ratio to boot).

I am wondering whether this is down to a flawed Windows installation to begin with:

- Display shows as "Generic Non-PnP Monitor on Standard VGA Graphics Adapter

- Which is some cruft from 2006

- Shouldn't there be a driver specific to the graphics card for the device?

- I know I saw the Boot Camp installer installing "ATI Graphics"; shouldn't the Display control panel be exposing that somehow?

I say "flawed Windows installation" because I know our IT dept installs from a customized Windows image. I wonder whether I'd be having this problem if they were installing from a vanilla set of authorized Windows 7 Enterprise install disks.

If you have any further thoughts, send them.

Holy crap. Hold the phone... Just discovered something. I'll write it up in full but wanted to post this so you didn't waste time with another response.

I discovered that the Display control panel does not list all available resolutions by default. In the Display control panel I clicked Advanced Settings. That brought up a dialog with the title Generic Non-PnP Monitor and Standard VGA Graphics Adapter Properties. In the Adapter tab, there is a button at the bottom named "List All Modes" which, when clicked, lists a bajillion resolutions, including our friend "2880 x 1800, High Color (16 bit)". I applied that and voilà.

Now if only I could fix the darn sleep problem (sleep still doesn't show up as an option in the Power Options > System Settings control panel). rrrgggg.

i have the exact same problem (no sleep option) and I can confirm this is only present if my macbook (13retina) is booted with wired ethernet.

connecting ethernet after startup maintains sleep option.

however, when mac wakes up it will not have the ethernet because windows can't handle plug&play with thunderbolt devices as per thoro's post.

if anyone is able to boot with ethernet plugged through thunderbolt, sleep and wake up connected to the internet please speak now..

Hi,
are you running on windows 7 32bit or 64bit ?

since I have the same problem as the guys

I had the same problems: no sleep mode option in start menu and no sleep mode option to choose in Power Options in Control Panel. All these problems were solved when I started the computer without the Thunderbolt-To-Ethernet Adapter plugged in as suggested in the previous post.

I have exactly the same issue after installing the driver for thunderbolt to ethernet adapter.

Sleep mode is greyed out. The adapter does not support plug-and-play.
