I have an Amilo-Pro 3505 with Windows 7 installed plus an external Samsung HDD on USB. If I issue a shutdown command, the laptop doesn't seem to shut down completely as the fan is still running. I cannot do much (the 5sec power button doesn't do anything), and have to unplug the HDD USB cabel to finally observe a shutdown. If I have the HDD plugged in, my laptop doesn't seem to start at all on power on (fans going, but black screen). (The same external HDD caused no trouble on my Acer Travelmate 2492 with W7)
Why is that? Do I need to set power options around?
