Windows 8 sleep with SSD (T430)

[simatran]

Hi all,

I've recently started using Windows 8 on my T430 with an Samsung 830 SSD installed. As with many people I've gotten used to closing the lid when I step away from the laptop. It previously would go to sleep and the sleep light would show. Now, I've noticed with the light does not turn on, and it doesn't wake up into the Win8 login screen. Rather, it acts as if its booting, but goes to the desktop instead of the new start menu. This has happened ever since I put a fresh install of Win8 on my SSD.

Could it be Win8's way of dealing with sleep and SSDs?

Just curious, thanks.

I cannot say why this is happening, but it sure sounds like hibernation.

You can disable hibernation globally by running

Code: Select all

powercfg -h off

in an elevated command prompt. However that will also disable hybrid sleep, which I think is a really nice feature, so I would personally leave it on. (Of course you can always re-enable hibernation by passing "-h on" instead of "-h off")

Or you could have a look at windows' power options. The fastest way to get there in Windows 8 is to right-click where you would normally open the start screen. Select "Power Options" from the popup-menu. Then click "Change plan settings" for the active power plan and "Change advanced power settings" on the next screen.

You can configure all kinds of stuff in the dialog that opens.
Check the configured action for the lid under "Power buttons and lid". If it's "Hibernate" then change it to "Sleep".

BTW: I don' know if it's relevant, but have you installed the power management driver for Windows 8? It's available for download on the Lenovo website.

Hibernation isn't set for the lid closing. However, I'll give the power management driver a go.

Installed the power management driver: no change.

Wonder what it could be.

Have you installed a proper graphics driver? Or, are you using the default Win8 driver?

[simatran]

Just using the pre-installed NVIDIA drivers.

[Neil]

How do you mean "pre-installed"? Didn't your first post say you installed Win8 yourself? If you mean, just the drivers including in Windows by default, you are probably missing some features necessary for suspend to work.

[simatran]

Sorry, I should've been more clear. I recently purchased a T430 with Windows 8 pre-installed. I ordered it with an HDD and put in the SSD by myself, using the recovery media to install Win 8 onto the SSD. The pre-installed Win 8 also came with NVIDIA drivers which for some reason was also put onto Windows recovery media.

I hope that clarifies the situation.

Ah, yeah, that explains it. At least we know you have the correct video driver installed from the factory image. I'm all out of ideas about the suspend issue, though.
