Hello! my computer refuse to stay on sleep mode. now i am using Windows 7, but in XP its the same. when i setting him in the "sleep mode" the computer shutdown but turn-up Immediately. i entered in the BIOS and saw the "Wake UP By USB" feature was on Enable mode. i switched it to Disable. but the problem is still there. Then, in another test, when i am set him in the sleep mode, before he got to shutdown i pull out all the USB connectors... Only then the computer doesn't turned-up ... How can i fix this issue? The USB device is the keyboard and muse only... Thank you, and regards... Hope my English are readable...
