A power supply that is designed to be outside the case of the computer. Most laptop computers use an external power supply rather than an internal one to reduce size and weight while the laptop runs on battery power.

How do you can start a Cessna 172 engine with external power?

To start a Cessna 172 engine with external power, first ensure the aircraft is in a safe position and the master switch is off. Connect the external power supply's positive lead to the aircraft's battery positive terminal and the negative lead to a suitable ground point on the airframe. Turn on the external power supply, then switch on the master switch and attempt to start the engine as usual. Once the engine is running, disconnect the external power supply in the reverse order of connection.


What is an internal power supply?

An internal power supply is usually a battery. An external power supply means the electric current that you get by plugging your device into a wall outlet. If you do not have to plug it in, then it has its own power supply inside the actual device, in other words, it is internal. Aside from a battery, it could have photovoltaic cells to generate power, or other internal sources of power, anything other than an external source.

Can the power supply cause the computer to be difficult to turn on?

Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300. One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs. External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.

What is internal device?

That is a device that is inside the computer. An internal hard drive, for instance, is physically mounted inside the computer. It is not made to be used outside the computer, though there are kits to convert internal hard drives into external drives. There are external storage devices that are made to plug into a USB port. External devices either require their own power supply, or they get power from a USB socket. Internal devices get their power from the power supply which is already in the computer.
