XPS 1530 w/ Vista 64: No sleep/hibernate?

Just finished installing Vista 64 on my new 1530, as well as all the drivers listed in the 1530 64 bit driver thread. There are no unidentified/uninstalled devices in the device manager anymore.
I did not load the ACHI driver during setup, but many people say that's not needed.

However, I can't seem to either sleep nor hibernate the computer. The options are just not there. I know in winxp you had to enable hibernation specifically but I could not find the option to do this, and I think sleep should always be an option? I've used vista before on a desktop computer and never had issues with this.

Is there a solution to this or should I try reinstalling vista with ACHI driver? Any chance it fixes something?

 

It has nothing to do with the ACHI driver. Though you may want to reinstall Vista just to make sure you use the ACHI(64-bit) drivers this time.

 

Yeah I guess i'll give that a try... Anyone have a clue why this might be happening though?

I installed from an MSDN vista DVD that included SP1

 

Well I just finished reinstalling vista 64 with ACHI drivers during setup and the sleep option in the shutdown menu is still greyed out and hibernate is not there at all

Edit: Just tried installing bios A09 (had a08) but no change

 

Yeah, AHCI has nothing to do with it in the first place and the bios update doesn't affect that whatsoever.

Just to narrow things down a bit, try this for me.

Open up Start Menu -> Accessories -> Command Prompt(Right Click and Run as Administrator) and type in:

powercfg /hibernate on

Press enter on your keyboard, close the window, and restart your computer and check if the hibernate option is there and if it works or is grayed out, etc.

 

I cannot explain why but I have recently installed x64 vista twice and both times I had this problem. Right after I installed x64 SP1 I tried to configure the power settings and was unable to get those options but after I installed all of the Windows updates and rebooted the options had changed. I was then able to see the sleep and hibernate options. I do not know if there was a update that fixed this but it seemed to fix itself after WU.

It probably is just a 64-bit driver compatibility problem. Windows Update is good at finding all the drivers you need so you don't really need to use the Dell support page to download all of them. It could be that you just needed the 64-bit versions to be installed by windows update and your all set.

Hopefully this works for the OP as well. If not, we'll come up with something else.

 

thanks all... installing all windows update updates fixed the problem

 

After some googling, I read somewhere it has to do with having a graphics card driver that supports sleep. I had the same issue of sleep being greyed (32 bit) just 3 hours ago after reformatting and after updating only the graphics driver, it was fixed. I might be wrong as I don't know anything about 64bit but I thought I'd mention it.
