I have a Dell XPS 17 (L702X) and the problem is that whenever I use the laptop on battery without it connected to AC it will only work for a random amount of time before it will suddenly shut down. This has been happening for a number of months now. The battery is new as I bought it a week ago—along with a new hard drives—and it still does this.

On AC power I can use the laptop for as long as I wish without it shutting down unexpectedly. The shutdown is hasted by how much I use the laptop for example it can be a hour or so if just left alone with just the desktop on screen. But if i play a game it will be maybe about 15 minutes.

  • Are you sure the new battery is really new, and also that it's not faulty?

  • Sounds like a faulty battery. BatteryInfoView can provide insight into what's going on—the logging feature can come in really handy.

As mentioned above, this seems like a bad battery, though new.

In Windows 7 or 8, open a CMD prompt as Administrator and enter

powercfg -energy

In a minute you'll have a report that includes battery condition, e.g.

Battery:Battery Information ...

Design Capacity 48600

Last Full Charge 46580

The difference between design and current (no pun intended) capacity gives an idea of the battery condition. See How to check your laptop battery health in Windows 7 for more detail (this works on Windows 8.1, as well).

Also go to Control Panel\All Control Panel Items\Power Options\Edit Plan Settings, Change advanced power settings and examine * Battery* settings to check if you're laptop is set to shut down when there is still considerable charge left.

    There seems to be a few threads on the web dealing with Dell battery charging issues. You could try the advice at computing.net/answers/windows-vista/…: shut and unplug laptop; remove battery; plug back in and run on AC adapter for a while, then shut down and reinstall battery. Check the power plan, though, to see if it;'s shutting down while there's still charge in the battery.
