Fuse is used to protect against over load. The fuse blows off if there is overloading in the circuit. This prevents the flow of current in the circuit beyond the position of the fuse. The equipment which is overloaded in the circuit is thus saved.
If you mean the fuse in the plug that connects to the mains... no more than a 5 amp fuse.
If the 2 amps is the output amperage of the power supply, the maximum that should be drawn from the unit is 2 amps. The load amperage that is connected to the power supply should govern the amperage of the fuse used. There is not much range there, the fusing could go from .25 to 2 amps. If the input amperage is 2 amps then the input and output voltage of the power supply should be stated.
Very unlikely. When a power supply "blows", a fuse is destroyed in the power supply. This is what the fuse was designed for. When a high voltage comes through, the fuse will burn out to prevent the surge from reaching the rest of the electronics. A surge protector does the same thing, but is better at catching voltage spikes than the power supply.

Electric power is available at places where a supply has been installed. The amount of power is limited by the supply company's fuse.
No... The power supply is simply a battery in the back of the laptop. But if you use a Desktop it is like any other power source.
The fuse for the auxiliary power supply in a 2006 Scion tC is located in the engine compartment fuse box. You can find this fuse box near the battery, and the specific fuse for the auxiliary power supply is typically labeled as "ACC" or "Accessory." Always consult the owner's manual for the exact fuse number and location, as the layout may vary slightly. If you need to replace the fuse, ensure the vehicle is turned off before doing so.
The only fuse located in a computer is the one in the power supply. It can be very dangerous to open a power supply without proper training. If you do not have the requisite training to repair a power supply, please do not attempt to open it. Your life isn't worth losing over a $50 hunk of metal and wires.
Could Be a fuse on the Circuit Board or The Power Supply Capacitors are bad.
Check the fuse of the power supply.
Try plugging in the computer;-).
You either have a bad circuit breaker (located in the driver's side fuse panel) or a short in the power supply to the switches.
