i want to mount some leds on my keyboard to make it look cooler. i want to know how much power is available at the PS/2 port.
i checked the mainboard manual, and it doesn't say anithing. just that is protected by polyfuse.
anyone knows how much can i use? i think that 500mA is the limit.

On mine it says it can supply 500ma @ 5v. Also take in account the current needed to power the keyboard itself.

I put a array of high viewing angle leds under the my keys and the whole entire keyboard is blue. 8)

If i can find where i put my el cheapo digi-camera, yeah...

I also replaced the mouse wheel with a perspex one and and put lights behind it. Also changed the "laser" in the mouse to blue with a LED. I got a picture of this one somewhere...

Any keyboards I tested only used 80 - 120mA themselves (80 with the 3 indicator leds off, 120 with all 3 on). That leaves 380mA, enough to light a couple of Led's.
