Electrical tips for HP Laptops

Proper maintenance of the notebook's electrical components, such as the power adapter and power cord, can keep both you and your notebook safe from potential harm. Do not do anything with the notebook or its components that you would not do with other kinds of electrical devices.

Use only the power adapter that came with your HP notebook.

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 battery performance, refer to Improving Battery Performance (Windows 8, 7, Vista).

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.

Always plug your notebook power supply into a grounded outlet.

If you do not use a grounded outlet, you may notice an electrical tingling sensation where the palms of your hands touch the notebook during use.

All power adapter certification tests for HP notebook computers are performed using a grounded power adapter. Damage can occur if an ungrounded power adapter is subjected to power surges or electrostatic discharge.

Always store your notebook power cord loosely in a bundle.

Gather the power cord loosely in a bundle when packing it away for storage or transport.

Use a "figure 8" pattern when bundling the cord. This allows for easy storage of the cord, prevents unintentional breaks in the wires, and keeps it from getting tangled.

Never wrap your notebook power cord around the power adapter or any other object.

Do not wrap the power cord around the power adapter or any other object as this could inadvertently break the cord's internal copper wires.

Broken wires can short circuit both the power adapter and your notebook's internal power supply. Broken wires can shock anyone who touches the cord and may also present a fire hazard.

Use the notebook power adapter on a hard, flat surface.

When a high number of applications are running or when the battery is recharging, the power adapter may be warm to the touch when it reaches its power limit.

Connect the power adapter to a good quality surge protector if your local power supply is unstable.
