| Battery and power adapter |
| The power supply of notebook computer includes two parts: battery and power adapter. The battery is the power source for outdoor office of notebook computer, and the power adapter is the necessary device for charging the battery, which is also the preferred power source for indoor office. 1 battery The essence of a laptop battery is not that different from a regular charger, but manufacturers usually design and package the battery according to the characteristics of the laptop, packaging multiple rechargeable battery packs in a single designed battery shell. At present, the mainstream notebook generally USES lithium ion battery as the standard configuration, as shown in the right picture, in addition to lithium ion battery, the battery used in the notebook also includes nickel chromium battery, nickel metal hydride battery and fuel cell. 2 power adapter When using notebook computers in the office or in an area with power supply, the laptop's power adapter is generally used to power the laptop, as shown in the picture on the right. The power adapter can automatically detect 100~240V ac (50/60hz) and provide stable low voltage direct current (12~19V) for the laptop. Laptop computers usually have an external power adapter connected to the main computer with a wire, which can reduce the size and weight of the main computer. Only a few models have the power adapter built into the main computer. The power adapter of notebook computer is fully sealed miniaturization design, but its power can reach 35~90W generally, so the internal temperature is high, especially in the hot summer, touch the power adapter in charge will have a hot feeling. When the laptop is turned on for the first time, the battery is usually not full, so the user needs to connect to the power adapter. If the laptop is not used for a long time, it is recommended that the user unplug the battery and store the battery separately. Another use of batteries, it is recommended that at least once a month to conduct a study of the battery, discharge naked. Otherwise, the battery may fail due to excessive discharge. |
