Portable notebook computer largely depends on the support of the battery

Mobility is the most important features of notebook computers

, how to improve its flexibility and stability are the most important issue faced by notebook computer, notebook computer power supply as part of the work is the key to ensure their effective link. Laptop power supply system after the CPU and the motherboard is the display of the third key component. Power systems include the power adapter, rechargeable battery and power management systems.

Taking into account heat dissipation of power adapter are independent of the host laptop, the generally applicable 100V-240V AC input, the AC into DC for the main work. Chu Ci well as machine features battery charging, to prevent prolonged charging shorten the battery life, machine equipped with test circuit and charge status indication and can be cut off automatically after the battery is full charge circuit. Thus, high requirements of notebook PCs, to test the stability and robustness of the main indicators of the power adapter. In order to avoid the ripple coefficient of input power is too large or sudden shock and burn high-current power adapter, as connected to the power outlet with overload protection.

Event of a power failure situation, the battery would demonstrate the superiority of it. Portable notebook computer battery support largely depends on the battery is the heart of the entire power system, we can not underestimate it. The first is the notebook used in nickel-hydrogen batteries. Although this battery has a good cost performance and higher power, but the battery discharge time of less sustained, it will soon be replaced bylithium-ion battery. Higher energy density lithium batteries can be charged at any time, and continued to discharge time is long, usually about 3 hours. To improve battery performance while increasing battery capacity, high-end laptop floppy structure constant improvement intelligent slots, in addition to storage devices such as floppy, it could take a second battery doubling the battery capacity.
