I have just set up another computer and when I tell it to sleep or it automatically goes to sleep I can't wake the computer because it cuts power to all the USB ports, so that includes the keyboard and mouse. In addition for some reason the power button will not wake the PC. I have tried changing the ACPI settings to S1, S3 and S1&S3 (S5?). I can't find anything else under the power or USB settings also there doesn't seem to be anything useful in the BIOS updates. I'm sure that getting a PS/2 keyboard/mouse would solve the problem but that would be complicated as they are outdated.
My current solution is to disable sleep, has anyone else got a better solution?
