2 About your computer This section provides more information on the components which can be found in your computer. Power adapter Power adapters are used to supply power to portable computers, tablets, and certain desktop computers. The Dell power-adapter kit consists of the power adapter and the power cable. The power‑adapter rating (90 W, 65 W, and so on) depends on the device it is designed for, and the power cable varies based on the country where the power adapter is shipped. CAUTION: To avoid damaging your computer, it is recommended to use only the power adapter shipped with your device or a Dell‑approved replacement power adapter. Battery Batteries are classified by their power ratings, such as 45 WHr, 65 WHr, and so on. The battery allows you to use your device when it is not connected to a power outlet. The life cycle of the battery is the number of times it can be discharged and recharged without affecting the operating time significantly. After the battery life-cycle reaches its end of life, you must replace the battery. Depending on the computer model, the battery on your computer may be user-replaceable or may require a Dell service technician to replace. NOTE: High-capacity batteries generally have a longer life-cycle, since you need to charge high-capacity batteries less often compared to low capacity batteries. NOTE: For tips on improving the battery life, see Improving battery life. NOTE: Dell Power Manager feature is not supported in Alienware systems. About your computer 13
