Recently, my husband borrowed my computer. He unplugged everything, and just took the pc without its keyboard or any other peripherals. He used his own keyboard and mouse. Hes use it for about half an hour, but he didn't install anything. I got it back, and now it suddenly doesn't recognize my good old wireless keyboard, which I've used for about two years, anymore. It (the pc) starts complaining immediately upon startup. We've checked the keyboard's batteries and they seem fine. Any ideas?
If it's a Logitech keyboard, you may need to resynch the base with the keyboard and mouse. There is a momentary switch (button) on the base and also on keyboard and mouse. For the keyboard and mouse you will need a pen or some other awl-like device to press the button. Also make sure the the base's proximity is not a problem, especially if it is infrared and not radio controlled.
