hey guys its been a while since i post something here hahaha. anyway i have this i8 wireless multifunction keyboard that comes with a usb dongle. the problem is whenever the dongle connect to the pc, and i want to put the pc on sleep, the screen goes black but the system still running. when wiggle my mouse, the screen light up back like nothing happen. i've already untick "allow this device to wake the computer" on every single hardware that is a part with this thing, which in device and printer called "2.4g composite devic" like legit without the e. they probably forgot that when making this thing hahaha. anyway the pc sleeps just fine when the dongle is unplugged, but i need to restart my pc first for it to work. soo yeah anyone knows how to deal with this problem? thank you soo much
