Turn on the laptop and check the status of the battery. Test the length of time that the laptop battery charge is held by unplugging the laptop from the power source and leaving the computer on but idle. Compare this time with the time that Compaq promises a new battery will last. If considerably shorter, continue following the next two steps to enhance the battery life of your Compaq laptop.

4
Save battery time when using your Compaq laptop by shutting off peripheral devices and services that you are not immediately using. For example, keep your wireless Internet card (WiFi) off when you are not browsing the web. This is the most notable cause of rapid power usage in a laptop.

5
Dim the brightness of the Compaq's screen as much as possible to extend your laptop battery charge. This is the second major cause of rapid power usage. Also, unplug any USB devices such as external hard drives, as these derive their power from the computer itself and will quickly drain your laptop's battery charge.
