hello some time back, i configured my desktop to enter sleep mode and wake up by pushing the power button [on the tower]. it worked an absolute treat! around the beginning of march, I attached a wireless keyboard and mouse. since then and prior to this issue occurring [first report 6 april] I've installed automatic updates only. i'm not a computer buff. I have spent hours trying to figure it out and I have done much configuring [all undoable] to get it back to how it was. the original configuration: power management 'balanced' with my screen to go dark at 10 minutes and to enter sleep mode after 15 minutes. I believe the only tweaking I did was to enable wake timers and I assigned the power button on my tower to, when pressed, enter sleep and wake up. here's what used to happen: computer on, push power button, sleep, push power button, wake up [revealing the screen I'd been working on]. beautiful! now, pressing the power button to wake up the computer, it starts to load as if from a shut down state and then reveals a screen from the bios manufacturer [American megatrends] reporting a hyper transfer sync flood error. I've never ever had to update the bios of any computer I've owned; but then again, this is the first time I didn't buy thru dell. things I've done to correct the issue: I created a new power plan that prevents the HDD from shutting down [so, screen dark 10 mins, sleep 15, hdd never]. i also set to automatic [from manual] the 'windows driver foundation - user-mode driver framework. I read about usb suspension [in sleep mode] and checked that it was enabled [should it be disabled?]. from that, I followed [Microsoft] instructions and opened my device manager, viewed my connected devices and unchecked 'allow this computer to turn off this device to save power' for all usb connected devices [including my wireless mouse and keyboard, both being configured to 'wake the computer' but which always failed in any event]. this therefore tells me that all my usb connected devices remain 'powered'. bollocks! it failed. I read also where it was unlikely the bios could read a wireless device! so, I shut it down, disconnected my wireless keyboard and mouse, connected my usb keyboard and mouse, started up, checked for updated device drivers for both [all current], both checked to 'allow wake up', hit [soft button] sleep, let it stand a few minutes, hit the space bar; nothing, waggled the mouse; nothing, pressed the power button, and it loaded as if in a shut down state [revealing the hyper transfer sync flood error page again]. I requested the hotfix from this link: http://support.microsoft.com/kb/974476 but i'm hesitant to install it... please, can anyone help me with this issue? tia ps: I've read too about conflicts with audio drivers [2 per device manager: 'amd high definition audio device' and 'realtek high definition audio'].
