What is power supply in laptop?
A laptop power supply is a charger that is used to provide power to a laptop computer. It typically plugs into a wall outlet or a UPS for external power and converts the AC current into a DC current that can be used to power the laptop’s internal components such as the processor, RAM, hard drive and other peripherals.
Most laptop power supplies support multiple power levels ranging from 65 watts to 180 watts, with 65 watts being the most common. The wattage of the power supply you need will depend on the hardware specifications of your laptop, as higher wattage power supplies provide more power for larger and more powerful components.
Additionally, laptop power supplies are manufactured with different type of plugs and different output voltages, so you will need to select the correct power supply for your laptop.
What are the 3 types of power supply?
The three main types of power supply are direct current (DC), alternating current (AC), and switching power supply (SPS).
DC power supplies use a direct electrical current to power the device. This type of power supply is used in devices that need constant power, such as hand-held electronic devices or consumer electronics.
DC power supplies are commonly found in items like laptop adapters, USB chargers, and battery chargers.
AC power supplies use alternating current, typically found in a standard electrical outlet. This current is then converted into a lower voltage so that it can be used safely with the device. Many larger electrical devices, such as computer monitors and TVs, use AC power supplies.
Switching power supplies use a form of rectification to transform AC power into DC. This type of power supply is used in devices that take up a lot of power and require the device to turn on and off quickly, such as servers, video game consoles, and desktop computers.
How do I check my power supply?
The best way to check your power supply is to use a multimeter. A multimeter is a device that can accurately measure voltage and current. To begin, you will need to turn off your computer and unplug the power supply.
If you can, unplug any cables connected to the power supply so that it is completely isolated. Make sure you are wearing appropriate safety gear such as rubber gloves and safety goggles.
Next, take the multimeter and set it to the DC voltage setting on a scale of 0 to 20V. Connect the probes of the multimeter to the two power cables of the power supply. The green wire is the main power cable and the black wire is the ground cable.
Make sure the probes are connected firmly, but not too tightly. Turn on the multimeter and check the voltage output.
The measurements you should expect to receive are +3.3 volts for the yellow/orange wire, +5 volts for the red/pink wire, and -12 volts for the blue/gray wire. If your readings are outside of the range listed above, then your power supply may need to be serviced or replaced.
If the voltage readings all fall within their respective ranges, then it is likely that your power supply is functioning properly.
It is important to keep in mind, however, that a multimeter is only capable of measuring voltage. To test the overall functionality of the power supply, you may need to purchase a power supply tester.
