Reading Time: 6 minutes

This can be very frustrating. Imagine yourself doing very important work and suddenly the laptop battery is getting empty. What if there is no power supply or you are outdoors where you don’t have the option to recharge your battery. Here are some steps that can be tried to reduce the power needed from the battery. These steps allow you to prolong your battery life so that you get some few minutes or an hr additional than in the normal mode.

  1. Adjust screen brightness

In addition to the hard drive and (if available) the DVD drive consumes especially the laptop monitor much power. By dimming the screen brightness down to just barely detecting the contents, you can save a lot of energy and save on your laptop battery. In many places, apart from sunny places in the open, a weaker luminosity of the display is completely sufficient to recognize all screen contents well.

Typically, there are function keys on each laptop keyboard that allow you to easily control the brightness. These buttons are labeled and designed differently depending on the manufacturer – mostly it is a small sun symbol. Typically, you activate these buttons by pressing the Fn key. “Fn” stands for “Function” or “Function”. You can find out how to adjust the brightness on your laptop in the operating instructions.

  1. Disable unnecessary functions

If you want to tap a letter in the dark on the balcony in the dark at night, a keyboard backlight is handy – but it also consumes a lot of power. If your laptop has such a feature, turn off the keyboard light if you do not need it to save energy. This is usually the case for laptops with a lighted keyboard via a function key; for laptops from Acer, this is the F9. Which key it is with your model, please refer to the manual.

If the battery is low, you should also turn off Bluetooth and Wi-Fi if not needed. Both functions constantly try to connect to other devices while consuming a lot of battery power. Deactivating Bluetooth or WLAN is easy via the function key or in the control panel. To do this, click on Start> Settings> Network and Internet> WLAN and switch off the wireless network. To turn off Bluetooth, click Start> Settings > Device> Bluetooth and press there by clicking the slide switch.

  1. Close programs in the background

Just like smartphones, many programs run in the background on the laptop – often without the user noticing. In some cases, even after quitting, applications still have some remaining active – which can also put pressure on the battery. Especially browsers are vulnerable here because they have many additional programs (add-ons), which sometimes even run if you have actually closed the browser long ago. To detect such power guzzlers, use the Task Manager in Windows 10, for example.

Instructions: Close programs via Task Manager

Hold down the key combination CTRL + ALT + DEL for a moment.

In the menu that now appears, click Task Manager to launch the program, where you can see all the programs and processes running on your computer. If there is an application that you have already finished, you can also remove the items left in memory. You can recognize such elements by the fact that program icons of actually finished programs are still visible.

  1. Remove all and any kind of external devices

Each device connected or docked to the laptop increases power consumption. Therefore, not only remove external drives, but also remove USB sticks from the device if you do not need them at the moment. A big power consumer is a mouse, which you can easily replace with the touchpad while you’re out and about.

  1. Start and adjust energy saving plans

Windows 10 also offers predefined power plans: These are combinations of settings in which certain system settings are combined with each other to regulate the energy consumption optimally. Windows 10 is usually equipped with the following three setting options:

  • balanced
  • power-saving mode
  • maximum power

The ” Balanced ” mode provides a workable mix between savings and performance. The device, therefore, does not work though with the highest performance and also shuts down relatively quickly if it is not used, but so also energy is saved up. In the ” sleep mode “, the computer restricts some functions, such as the display brightness and processor performance. Many laptops automatically switch to an energy-efficient mode whenever they are disconnected from the network. This can be clearly recognized by the fact that the screen suddenly darkens. ” High performance”Means high energy consumption, but you can also work in all programs at the maximum speed.

In Windows 10, call the power plans on Start> Settings> System> mains operation and energy savings. There then click Additional power settings to the settings menu Power Options to open the Control Panel.

Each of these energy savings plans can be adapted in great detail to their respective needs. The default settings in Windows 10 are in principle sufficient for normal users, so changes are usually unnecessary.

Those who still want to take a look “under the hood”, click on the menu power options on plan settings change> Change advanced power settings, and then click a + in front of a special setting. If you have inadvertently changed something and want to restore the original configuration that goes by clicking Restore Defaults.

  1. Change the time for low battery warning

Which battery level will warn your notebook before the end of battery life, is under the Advanced Settings set. To work longer with the notebook, this value can be changed. In the section battery, see Low battery capacity the percentage value at which the first warning is displayed. You can adjust this value to your wishes – or even switch off the warning completely. But more importantly the value at Critical battery capacity. If the energy store has only the value displayed there, Windows immediately triggers a corresponding action. These are set in action for critical battery capacity firmly. Normally, the options Hibernate or Shutdown are available. Who needs a little more time before Windows is activated when the battery is low – for example, important, yet save open documents – can the value for the Critical battery level reduce.

This may not work on some notebooks because the manufacturer has set this value to five percent. In this case, you can reduce the critical battery capacity on Windows 10 as follows:

Right-click Start, and then click Command Prompt (Administrator) .

If the value for the critical level approximately three percent want to change, enter the following command:


After rebooting the laptop, you should now be able to enter “3” at the critical battery capacity value. This can probably win at least a few minutes of battery life. But be careful: If you set this value too low, the notebook simply turns off when it has used up the power. Time to save then no longer remains.

  1. Smarter loading – so your calculator has more of it

Contrary to the widespread assumption that frequent charging could damage the battery, this is no longer the case with modern laptops. A simple but effective tip is, therefore, to load your notebook at every opportunity. However, you should always avoid completely recharging the battery. If your battery is 70 percent charged, you’ve achieved a good charge mark. It is also unfavorable to empty the energy storage to less than ten percent because the battery can be damaged in the long term and the life can be shortened.

If you use the laptop power supply permanently, it is advisable to remove the battery – if this is possible with your laptop – and store it in a cool place. Disparities are experts on whether the energy cells in the refrigerator. But even a cool cellar with about 15 degrees is probably sufficient to slow down the aging of the battery. In any case, you should pack the energy storage firmly in a tight plastic bag to prevent the formation of condensation. On the other hand, leaving the power adapter connected to the laptop will result in slightly increased power consumption. However, this does not shorten the life of the battery – because the lithium-ion batteries used in all modern notebooks stop the charging process automatically.

  1. Switch on hybrid graphics only when needed

Some notebooks have in addition to the built-in graphics chip a special graphics card, also known as “hybrid graphics”. As a result, the devices bring about more performance in games. If you want to save energy and save the laptop battery, you can do without the power of this additional graphic and disable the power-hungry additional graphics card.

For products of the manufacturer Nvidia, for example, this is done via the Nvidia system control. If you there is the setting Integrated Graphics choose the graphics card remains off. You can, however, set exceptions. Radeon graphics cards from AMD, on the other hand, usually require manual deactivation in the Device Manager of the Control Panel.

Finally, more battery life for the laptop

By following the UPDATED energy-saving tips, you should be able to significantly increase the battery life of your laptop. Then, not only do you quietly finish your email, but you’ll also have enough energy to check out the latest Facebook photos and videos from your friends at the coffee shop.
