that may not be possible to fix high amounts of irq's from key/mouse/touchpad are generated by the hardware when you use them. You can't really stop using the keyboard. You could try to stop using the touchpad and mouse, and see if that significantly reduces the amount of irqs. It may be the case that the windows drivers for your touchpad/mouse etc. put the hardware into a battery saving mode. In that case, we can't fix anything unless we have the hardware specs either...
