The computer plug the power adapter?

Computer 'power adapter' is the power of the laptop, one end on a laptop, the other end into the power outlet. Power adapter is a small portable electronic devices and electronic power supply power transformation equipment, generally composed of shell, power supply transformer and rectifier circuit, according to its output type can be divided into the ac and dc output; According to the connection mode can be divided into the plug wall and desktop type. Used in telephone composite aircraft, game consoles, the language repeater equipment, walkman, notebook computers, cellular phones, etc. The computer power adapter plugged in. Type: depending on the type of plug the power adapter is plugged into an outlet ( Two phase or three phase) ; Features: small portable electronic devices and electronic power supply power transformation equipment, generally composed of shell, power supply transformer and rectifier circuit, according to its output type can be divided into the ac and dc output; According to the connection mode can be divided into the plug wall and desktop type. Other parameters, rated voltage 220 v, three-phase plug into ( Ground wire, wire, zero line) Less, two phase ground. Notebook welly, usually in the fuselage at the left side, close to the screen position. You plug the power adapter is ok. Should try to avoid draining rechargeable battery went dead, such as battery because this will give a lot of pressure and damage. More feasible approach is in power the remaining 20 - Recharged by about 30%. In fact laptop lithium battery charge in the 'run/' the number of times is limited, all light recharging will shorten the battery life. At the same time, the battery charge shall be conducted in a dry place, also attention to the problem of heat, this is the enemy of the battery. Plug is inserted in the power adapter, use need not take down the battery power adapter, notebook now design is full of battery directly to stop charging, so don't worry about the battery will be bad, and if the battery is full of with an external power supply, the power converter is to skip the battery directly to your computer power supply, so don't worry about the battery, the last way, better ways of preserving battery is usually battery is on the computer, about a month with a battery, and then use the battery capacity is less than 10%, with the power converter is full, repeat every month, the battery life expectancy. If the power adapter is plugged into the computer, the computer is usually no battery power, but is some computers require you to install batteries, or it will run on a fixed low frequency, say in the running of computer power supply power requires a lot of program may be because the adapter when the battery power is not enough and need. Common use such as battery does not filled with while filling, until full. But after the battery itself will have consumption, even if you at any time is done with the power adapter, battery capacity will decline, after a period of time less than after the BIOS Settings of the battery capacity will be automatically filled again. Now some new computer power management software can set the charging threshold ( The battery capacity is lower than what value only when charging, charging to what capacity and stop) So to have certain help to the life of the battery.
