Notebook Battery Protection Tips

The maximum charge capacity of every battery decreases over time and with use. The rate at which this capacity decreases can vary depending on product configuration, product model, operating system, type of software used, power management settings, and other factors.

Tips for conserving notebook battery power

  • Reduce the brightness of the screen to the minimum readable level. Use the Fn and F7 or F8 keys to adjust the brightness.

  • Reduce the number of open applications. Each open software application uses memory and power, even when the application window is minimized. Close software applications to conserve battery power.

  • Remove peripherals when not in use. External hard drives, CD-ROMs, Zip drives, PC cards, and other peripheral devices can draw power from your battery even when they are not in active use. Disconnect them when you are finished using them.

  • Reduce the speed of your processor. The faster your computer works, the more quickly it depletes battery power. You can extend the charge of your battery by slowing down the processor speed.

  • Turn off wireless. If your laptop has one, press the Wireless On-Off button so that the wireless and wireless light turn off.

  • Change the power option setting. Select either HP Recommended or Power saver to conserve battery power.

Tips for Longer Laptop Battery Life

  1. Dim the screen – By far the biggest power drain on most laptops is the screen. Or, to be more specific, the screen’s backlight. This is what enables you to see the colours on an LCD screen, and some older laptops have power-sapping fluorescent backlights. Modern laptops have LED backlights, but even these use a fair amount of juice.

  2. Change the power settings – By default, your laptop might be set to Windows’ ‘Balanced’ setting rather than Power Saver. In the Control Panel search for Power Options and check which Power Plan is selected. Don’t forget that Windows uses different power and performance settings depending on whether it is running on mains or battery power.

  3. Disable Wi-Fi and Bluetooth – If you’re not using them, disable Wi-Fi and Bluetooth. Both radios can use a fair amount of power, so it makes sense to turn them off when you’re on battery power. Most laptops have a switch or key combination to disable Wi-Fi, but Bluetooth can be trickier.

  4. Don’t leave your laptop on permanent charge – Lithium-ion batteries are relatively clever in that they can’t be overcharged, but it’s not good for the long-term health of your battery to leave your laptop always plugged in to the mains. Some manufacturers (including Sony and Lenovo) provide a utility which limits the battery from fully charging.

  5. Upgrade to an SSD – Mechanical hard disks, which are still common in laptops, require a fair few watts to spin their platters. A solid-state drive, on the other hand, uses less power as it has no moving parts. Although you won’t see a huge improvement in battery life from this upgrade, it will have the extra benefit of making your laptop an awful lot quicker.

  6. Manage your memory – If you’re the sort who has 10 or even 20 tabs open in your web browser, you’ll benefit from longer battery life by culling those tabs. The same goes for running lots of applications at the same time. When you run lots of programs, or have lots of photos open in an editor, you’ll use up all the free system memory. Anything extra has to be ‘paged’ to the hard disk, which as we’ve said, is a mechanical device in many laptops.
