Battery Tips:

How to Extend HP Compaq Business Notebook Battery Life?

You can make your hp compaq business notebook laptop run longer on its battery by turning off or reduce all the things that expend power in your computer. If you are going on a long trip, or just taking your laptop to a local coffee shop, use these tips to help your laptop's battery power last longer.

1. Switch off the wireless card if you do not plan to access your network or Internet connection. For Mac laptops, there is a button for powering on and off your wireless device is found on the toolbar at top.

2. Turn the volume level down, or mute it, if you do not plan to use it.

3. Reduce the LCD's brightness level. If you use your hp compaq business notebook laptop in a well lighted area or outdoors on a sunny day, try setting it at two or three bars.

4. Disable Bluetooth. If you don't use this device, you can safely disable it to avoid draining your hp compaq business notebook's battery

5. Learn to single-task. PC memory that is in-use takes more power to hold data. Also, using more memory might mean using more swap or virtual memory space on your laptop's hard drive. All of this puts an additional drain on your laptop battery. Instead of leaving multiple applications and windows open, use only what you need at any given time. If your laptop has plenty of memory, then keep multiple applications open to avoid loading repeatedly from the hard drive. Close all the applications that run in the background on your computer like your PDA syncing software or USB hard drive backup software.

6. Run simple applications that don't use much RAM, disk drive or processing power. Need to write a letter? Use a basic text editor rather than the processor and RAM heavy Microsoft Word. Graphics heavy applications like games or movie watching are especially hard on the battery.

7. Avoid extreme temperatures. Batteries rely on basic chemistry and will die faster at extreme temperatures. Try to charge and use the battery at room temperatures.

8. Use the power management settings on your computer that come built in. On Windows XP, click "Power Options" in your control panel. On a Mac, look for "Energy Saver" in System Preferences.

9. Unplug external devices such as a USB mouse or an external drive.

10. Shut down or hibernate the laptop rather than using standby, if you plan on not using it for a while. Standby continues to drain energy to keep your laptop ready to go when you open the cover.

11. Clean your battery contacts. Clean the battery's metal contacts with rubbing alcohol on a damp cloth. Clean contacts increase the energy efficiency.

1 . What is hp compaq rechargeable laptop battery self discharge?

Primary hp compaq laptop battery or full charged secondary battery, when put aside for a period, it s capacity will decline or lose, this phenomenon calls self discharge that is electricity flee away. It is decided by the inner electro-chemistry system, similar to water leakage from pond or reservoir.

2 . What is the ambient temperature affects the hp compaq laptop battery performance?

Low temperatures (e.g. -15oC) will obviously reduce Ni-Cd and Ni-MH battery discharge rate. At -20oC electrolyte is at its freezing point, charge speed will greatly slow down. At low temperature (under -15oC) charge will raise the internal gas pressure and probably unseal the safety vent. Ambient temperature of 5oC to 30oC is the best range to get effective charge. Generally with temperature rising charge efficiency will become higher. But when the temperature rises to 45oC or higher, the materials performance in the battery will be degenerated and battery service life will be shorten greatly.
