We all love it when our laptops operate for long hours without plugging them to the AC power supply. How well you use the laptop battery determines how long it can work without requiring recharge. Ensure the laptop is unplugged on the AC power supply when the battery is fully charged, this ensures the Lithium-ion batteries do not get overheated. The voltage dispensed by the battery cells is dependent upon temperature; higher temperatures inhibit voltage generation. High temperatures convert Lithium-ions to Lithium metal, a material that inhibits current flow in the opposite direction that guarantees the cells are recharged. The dissipated heat also affects other laptop components such as the hard disk drive and Central Processing Unit (CPU) by increasing data latency because of delayed operation of heated components. Below are some tips on how to get the most out of your laptop battery.
Plug Battery from Power after Full Charge?
One discouraging aspect of portable electronic devices is the limited hours in which their batteries operate. A typical laptop battery operates for three hours as a stand-alone source of power, this operational time diminishes with use as the Lithium-ion cells age. To get round this problem charge the laptop batteries to full capacity then detach it from the AC power. This way, the laptop battery would last longer by restricting conversion of Lithium-ions to Lithium metal. It may be helpful to have a spare laptop battery to use it in alternatively with the charging battery.
Wi-Fi Will Leave you Drained
Wireless communication options such as Bluetooth, infrared and Wi-Fi drain laptop batteries since they have to power up the chips responsible for maintaining a steady stream of information interchange. Connecting to the internet via Wi-Fi consumes about 20 watts of power while in use and about 17.5 watts when in idle mode. Wi-Fi ranks as the third main power consumer of laptop battery right after the CPU and the DVD ROM. Use Wi-Fi when powering the laptop from an AC power supply and remember to switch it off while using the laptop battery.
Dim your Screen
Liquid Crystal Display (LCD) monitors contain tiny bulbs that control the brightness of your laptop screen. Bright screens consume more energy since the bulbs are operating in optimum mode. Dimming the screen helps to reduce the power consumption of the laptop batteries by cutting down on operating voltage of the bulb. To achieve a balanced outlook adjust other screen functions such as contrast ratio, color and resolution.
Leaving you laptop in standby mode continues consumption of power and laptop may go off without a warning. Keeping the laptop in hibernation mode instead of standby increases the up-time of the laptop battery up to 6 hours depending on the model. Hibernation saves your workspace, so there is nothing really lost. In addition, disconnect all external devices that may be drawing power from the laptop battery, these devices include external hard drives, external keyboard and mouse, Wi-Fi adapters, camera, extended monitors, external DVD ROM and speakers. Ensure the laptop is unplugged from the AC power supply when you are not attending to it, fluctuation in power level may damage the battery.
