Notebook Computer Power Tips
Laptop computers are meant to be portable, and you might understandably be frustrated if you have to spend more time with your computer connected to a power outlet than you would like. It may be years before a company invents a HP laptop battery that allows a user to go days between battery charges, but there are several things that you can do with the laptop you have to increase its battery life now.
Optimizing Operating System Settings
Every version of Windows includes settings that you can customize to optimize your computer for Sony laptop battery life. Double-click the "Power Options" icon on the Control Panel to access these settings. If the Control Panel is set to display items in the "Category" or "Home" view, click "Mobile PC" in Windows Vista or "Hardware and Sound" in Windows 7, and then click "Power Options." Depending on the version of Windows installed, you can simplify the process by clicking the "Power Saver" radio button. You can also drill deeper into your options and limit the maximum speed of the processor or configure the hard drive to shut off after a period of inactivity.
Lowering Screen Brightness
The maximum brightness of a laptop screen makes it more readable outdoors. However, a very bright screen is unnecessary inside and can even cause eyestrain. Lower the brightness of the screen to conserve battery life and protect your eyes.
Disabling the Wireless Adapter
The wireless adapter in your laptop continuously searches for signal from nearby access points, even if you are not actively using the Internet. Laptop computers typically have switches to disable the internal wireless adapter. Flip the switch to turn your wireless adapter off if you are not online. If your computer does not have a hardware wireless switch, open the Control Panel and browse to "Network and Internet," "Network and Sharing Center" and "Manage Network Connections" (Windows Vista) or "Change Adapter Settings" (Windows 7). Right-click the icon for your wireless adapter, and select "Disable."
Use the Hibernate Feature
Windows has two low-power modes that you can use to conserve battery life when you are not actively using the computer: Sleep and Hibernate. In standby mode, the computer continues to use power, drawing just enough power from the battery to maintain the contents of the memory. In Hibernate mode, the contents of the memory are saved to the hard drive, and the computer turns off. Both of these modes allow you to resume work quickly after turning the computer back on. Try using the Hibernate mode when you aren't using your computer, as it does not use the battery at all.
Keep the Battery Cool
A battery discharges more quickly when it heats up. If you work with your laptop on a surface such as a carpet or blanket, you can block the intake vents and prevent fresh air from entering the computer. This is a double-edged sword; not only does the heat reduce the life of the battery, but it also forces the fans to work harder, further increasing ibm thinkpad battery draw. Whenever possible, use your laptop on a flat, hard surface so the cooling system can work efficiently.
Minimize Optical Drive Usage
CD and DVD drives spin optical discs at high speeds to transfer data quickly. A great deal of torque is required for the motor in your optical drive to bring the disc from a standstill to several thousand revolutions per minute. Whenever possible, avoid using the optical drive unless your laptop is plugged into an outlet.
