Not sure if this is the best place it could be so please move is required.
But basically, I put my computer into sleep mode quite often. On my previous MOBOS, I would wake up the computer, and instantly the mouse/keyboard, flash drives would start working.
Ever since I installed my new Mobo and upgraded my system, awakening my computer from its sleep (via the power button) means the screen will switch on, but it takes about 15 seconds before my keyboard and mouse work. If I have my iPhone in, it would also take 15 seconds for it to start charging.
