what are the lights for? your keyboard or just to light up the other components?

wait the light is for the usb kb or just for the lappie kb? if that is the case. its better that you unplug the wireless kb when u're using the lappie kb then plug back the wireless kb when you need to go the distance

honest opinion? desk lamp la.. get those cheap ones which are not too bright but sufficient lighting fir kb usage. drawing too much power from the usb is a bad idea.

or you can just unplug the card reader since you're not reading from your cards all the time. its plug and play summore so not much problem

mic detects sounds la. not produce sound.

threadstarter, you can try to look for those kb with el lights on the button. such as logitech g15 or saitek ones(forgot wat model) both would suit your need nicely.

get usb extension cable also can wat. rm20 and below for 4 feet. sufficient
