For best performance, use only the power adapter that came with your HP notebook and configure your power management settings for optimal performance based on your usage habits.

For detailed information about power management options, refer to Managing Power Options (Windows 8), Managing Power Options (Windows 7 and Vista), or Power Management for Notebooks Running Windows 98, ME, XP and 2000.

Most HP notebooks utilize smart power adapter technology. They can use power adapters from other HP notebooks that may have different wattage requirements.

If you use a power adapter that has a lower wattage than your notebook requires, there may be some trade-offs. The CPU clock rate may be reduced to save power, which may cause programs to run slower, the battery may charge more slowly or not at all, or the power adapter itself may become warm to the touch.

Your power adapter's wattage information is printed on the bottom of the adapter itself.

For detailed information about battery safety, refer to AC Adapter Makes Hissing and/or Crackling Noise, and May Feel Warm to Touch.

For detailed information about verifying whether the power adapter is working correctly, refer to Testing and Using the AC Power Adapter.
