there's certainly enough power for that. Theoretically you should be able to run around 12 LED's on one USB.
Buy a USB hub and connect to one of the USB ports. This splits any one USB port into 4 or 7 ports(depending on the model of hub).

A 4 x 4 electronic display should run on standard a 110v 15amp plug. The displays don't draw that much power as most them run on LEDs. It can vary by model. What you can do is but a meter. you plug the machine into the meter and it will tell yu how much energy the machine uses.
try to run in safe mode... that's what i do...
Unfortunately not, if your port is USB 1.0, you can only run a USB drive that is 1.0 and you will have a very hard job finding one of those these days. You can run a 2.0 through a 1.1 port, but it will only perform at 1.1 speed.
it means it`s charging <plugged in via usb cable when PS3 is turned on or when using adaptor that uses wall socket>
Yes, you can run LEDs in Colorado. There's no regulation against them.
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Yes. But it will run only at 1.1 speeds.
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
LEDs are a kind of light that does not run on a bulb, like a typical lamp or overhead light. Rather, it is powered by a diode that emits light. This light is brighter, clearer, and less harsh than that provided by a bulb.
No. Windows does not (officially) support booting from a USB drive.
