Tip & How-To about Computers & Internet
The first step in troubleshooting battery life or charging problems is to check your owner's manual or the manufacturer's website for how to interpret the status LEDs on the laptop. The LEDs on the laptop will change color or blink when there's a charging problem. The operating manual for the laptop or a search of the manufacturer's web site should tell you exactly what the LEDs are indicating.
If the LEDs indicate that the battery is being continually charged, yet the battery only lasts a short period of time, there's a good chance the battery is worn out or defective. Before giving up, perform one last test to determine if the operating system software is interfering with charging. Let the battery charge overnight with the AC adapter plugged in and the laptop turned off. If the battery won't take a charge with the laptop turned off, you can try powering on, entering CMOS Setup, and letting it sit and charge on the Setup screen for a few hours.
Even if the battery is healthy and the laptop charging system is working properly, the battery lifetime will be variable with how hard you work it. If you're in the habit of turning the screen brightness all the way up and choosing the highest performance battery management profile, the battery will run down much quicker than otherwise. You could change your battery management profile if needed. There are a number of predefined battery management profiles in the operating system, accessible through the little battery icon in the system tray.
The ambient room temperature and the temperature of the laptop (if you've left it in a hot car in the summer or a cold car in the winter) will affect the battery life as well.
