Sleep Mode Still Freeze up, Win 7 RTM

Win 7 7100 x86 AMD x64 turion. . . All drivers updated

Had same issue as you. I use a gearhead usb mouse. . . . I was reading through this thread and it hit me (as it had froze up again after sleep about 5 minutes ago), BAM every time it freezes post wake up its at the exact moment of a mouse click.

Disabled the usb power management feature and have slept it several times, thusfar no issues!

Just to check.... How do you disable USB power Management?

I went in Device manager and unchecked allow it to wake, to no avail...

I would absolutely love to know if someone resolves this issue. I've been fighting with it all week!

Welcome to the forums adidosc. I hope so too!

USB > USB Selective suspend set to disabled for all 3 power options (performance, balanced, power saver)



I just put it through another test and still kicking. . . . fairly excited

Thanks. Seems to work for me too, which is really exciting.

cool so it wasnt just my computer and somebody has experienced this issue and we came to the same conclusion..:)

https://www.sevenforums.com/239287-post19.html (differences in vista's usb settings and finally looking into USB power management...)
it also seems like this is a definite solution until MS (or they might not even do anything, just issue a kb and be done with it...) says something about the issue

Perhaps this is an extension of this issue?

Computer does not shut down properly if Selective Suspend is enabled

what i am wondering is how they managed to bring this problem back...
it seems that they introduced new code in the USB stack or how they check for sleep functionality (or they might not even check...)...
what i liked about it is that it reinforced my actions on disabling unused USB controllers and root hubs (and checking whether they are used or not) really helps in battery life which is what this is trying to do...

For example, a driver can make the following devices idle: the host controller, empty the USB hubs (including the root hub), and the full range of USB devices that are supported by the operating system. The selective suspend functionality is primarily intended to conserve battery power in portable computers. USB controllers frequently use lots of battery power, even when no devices are attached to the computer.

it reminds me of how using a new networking stack (from scratch ) in vista caused problems that were fixed even in 9x and Nt and 2000 days....
