The power supply, AC / DC adapter or AC / DC converter

The most common type of AC adapter has a small box with a cable going to the Dell vostro 1400 battery and go to another cable from the wall. Typically, an LED light to say it is. (In you light up:) By the way, Apple notebook power adapters often have an LED that is actually on the side of the computer, not the adapter is built is so obviously no lights when connected to the computer. The adapter box does several things. It reduces the voltage of 120 volts alternating current from the Dell vostro 1500 battery power outlet to the usual 19 volts DC (which are marked with the exact voltage). Contains a noise filtering proxy. Often contains a circuit breaker or overload detection. If this is triggered, usually of when it will be suspended at all a few minutes. You, the voltage on the power supply with a multimeter. When disconnected from the Dell vostro 1510 battery, but still plugged into the wall, is normal stress can be 1 to 3 volts higher than the level to be output. Troubleshooting: power supply when plugging the adapter into the wall, but not on the computer Have you overloaded? Is the Dell vostro 1310 battery power strip is switched on and switched AC outlet? Is the power supply to the wall fully connected at both ends (try)? try, the adapter can be roasted, to borrow an identical adapter from a friend and see whether the place of work (but do not connect to your computer, or adapter can fry your friends). Troubleshooting: Check the output voltages with a voltmeter / multimeter For those of you with circular connectors, your task is simple. Measure the voltage between the indoor and outdoor use. A diagram on the adapter label will tell you have, positive and negative For those of you with electricity 3 Pin Dell vostro 1710 battery I have a chart for the suffering, however. If you try any of the three possible pairs of pins measure, you should get 20 volts from one of the couples.
