Hi all. T60p running Windows 7. When it's running, it's pretty good though I do on occasion bring it out of sleep mode and I'm missing a random USB device.

The bigger issue is that when I put it to sleep, say about 50% of the time, it doesn't go to sleep. Sits there whirring away until at some point it crashes and reboots. I reinstalled just about every driver I could think of - Lenovo, Intel or otherwise and it still does it.

Turned on crash dump reporting and ran WhoCrashed to read the logs and this comes up every time there's a crash:

This was likely caused by the following module: dozehdd.sys

I can't find any information anywhere about this thing. Anyone have any ideas?

I'd guess it is a driver for Lenovo's Active Protection system.
Try disabling it from the system tray or uninstall it as a test.

Active Protection was already uninstalled as a test, with no effect. As was Power Manager with all setting reverted back to Win7.

Got tired of this little game this morning and reinstalled Win7, and did not install any Lenovo software from anywhere other than what Windows offered from Windows Update (which happily covered everything except for the Sierra Wireless modem that I don't use anymore).

dozehdd.sys does not exist on my system anymore, so it likely is a Lenovo item. We'll see how it goes.

Thanks much.
