What is a medical grade power supply?
Medical grade power supplies have additional components to isolate line voltage from internal voltage. Usually a 1 to 1 transformer with current and voltage cutoffs are used to transfer the energy from the mains to the internal circuits of the power supply. there are also additional opto isolators on the power supply that keep the external power from having any wired path to the internal side of the power supply.

Where is the RAM located in a Toshiba 460cdt and how do you get to it?
Hi, to get to the RAM you must remove the battery cover and battery and remove the floppy or CD drive, in the space where those two were is a screw hole, remove those two screws and also the one in the middle of those two. Flip the laptop back up the right way, and the panel that the mouse buttons are on will lift up, the slot for external ram is under there. I'm not 100% sure how you go about installing the RAM it may be plug & play.

What is the purpose of the red button on your power supply unit?
The old power supplies had a large switch that was on the side of the computer to turn on the PC. The small, recessed switch on the back, if it exists, is to select the proper power line voltage. It should only be set to your proper voltage, and never changed while the power supply is plugged into the wall.
A symptom of the voltage switch being in the wrong position (at least if you have 110-120 volt power) would be if the PC doesn't boot all the way up. It might lock up right as the operating system starts to load.
What the voltage switch does is select a voltage doubler circuit if you are operating on 110-115 VAC. Otherwise, the rectifier bridge and capacitors inside are in normal configuration.
3. When selecting an input device what are the criteria for selection and evaluation?
creteria used to select an input device
