The computer's "power adapter" is the notebook's power supply, with one end plugged into the laptop and the other end plugged into a power outlet.
The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into an AC output type and a DC output type; And desktop. Widely used in telephone sub-machines, game consoles, language repeaters, walkmans, laptops, cellular phones and other equipment.
Plug the computer power adapter into a power outlet.
Type: Insert into the socket according to the plug type of the power adapter (two-phase or three-phase);
Function: Small portable electronic equipment and electronic power supply power conversion equipment, generally consists of outer casing, power transformer and rectifier circuit, according to its output type can be divided into AC output type and DC output type; according to the connection method can be divided into wall type And desktop.
Other parameters: rated working voltage 220V, three-phase plug is divided into (ground, fire, neutral), two phases are missing a ground.
The notebook's power jack is usually on the left side of the fuselage, close to the screen. You can plug in the power adapter.
Try to avoid the situation where the battery power is exhausted and recharged, as this will put a lot of pressure on the battery and cause damage. It is more practicable to charge when the remaining 20-30% of the power is left. In fact, the lithium battery of the notebook has a limit on the number of "lighting/charging", and all recharging with light will only greatly shorten the battery life. At the same time, the battery should be charged in a relatively dry place, and also pay attention to the heat problem, which is the enemy of the battery.
Plug in the power supply is plugged in the power adapter, do not need to take down the battery when using the power adapter, the notebook is now designed to stop charging directly when the battery is full, so don't worry about the battery will be damaged, and if the battery is full, it is still plugged in External power supply, the external power supply directly skips the battery to power the computer, so don't worry about the battery. Finally, the better way to save the battery is to put the battery on the computer, use the battery once a month, then use When the battery power is less than 10%, it is filled with an external power supply, repeated every month, and the battery life is the longest.
If you plug in the power adapter with a computer, the computer usually does not use the battery, but some computers require you to install the battery, otherwise it will run at a fixed low frequency, which is said to be running power requirements for the computer. In the case of a large program, it is possible to use the battery power because the power of the adapter is insufficient. When you use it normally, if the battery is not fully charged, charge it with the side until it is full. However, if the battery is fully charged, it will be consumed. Even if you use the power adapter at any time, the battery capacity will drop. After a period of time, it will be automatically filled after the battery capacity set by bios. Now some new computer power management software can set the charging threshold (that is, when the battery capacity is lower than what value is charged, and when the battery is charged to stop), this will help the battery life.
