Expert of the DSS380 School of Digital Security Pavel Belousov told what can be done to make the laptop last longer than the battery, writes "

Take care of your battery.

If the laptop is used as a desktop computer and is constantly connected to the mains, its battery is most likely " As planned, the battery should be discharged and charged all the time, then it will hold a charge for a longer time without being connected to the power supply..

If you have kept the device charged all the time, or if it is not a new laptop, then the battery most likely could exhaust all charge cycles and drain very quickly. Therefore, the expert advises to purchase a new one - it will hold a charge longer.

Remove Restrictions.

Some laptops have a charging setting to conserve the battery: they limit charging to 80% to prolong battery life.. During the blackout, you can turn off such settings so that the battery is charged as much as possible.. And then, when everything gets better, you can return this setting for the “health” of the battery. If you charge the battery to 100% for three months, this will not significantly affect the condition of the battery..

Replace hard drive.

Instead of a traditional HDD, it is recommended to choose a more energy efficient SSD, so the laptop consumes less power in the process of reading and writing to the hard disk, which will allow the laptop to last longer on battery.

Change your settings.

If there is a more modern processor, then you can see its settings. You can adapt the speed of work and, accordingly, the power consumption for certain tasks. That is, for example, if you are working with something simple, then it is laid out not at 100%, but at 5-10%. And by default it is configured that it works at full capacity.. In the settings you can limit this percentage, then the battery will last longer. This also applies to video cards.. You can also turn off additional devices, such as a Bluetooth mouse, speaker, and others..

Clean up.

It is better to cool the device and, as a result, keep the battery longer, replacing thermal paste (if necessary) and cleaning it from dust will also help..

Turn off unnecessary radio modules: Bluetooth and wi-fi.

When you have an active radio module, it constantly searches for a network. For example, if you do not have the Internet and you are just working on a laptop, this module should be turned off, because it works: it searches for networks, does not find them, tries to scan them, and this consumes electricity. It won’t add an hour of work to you, but such small adjustments will help you save somewhere a minute, somewhere five – so it’s worth doing..

Change screen settings and keyboard backlight.

Decrease the screen brightness and turn off the color adaptation function (and similar: smooth window minimization, for example, various audio and visual effects - they consume additional battery power) and keyboard backlight. And in general, return the screen settings to the basic ones, turn on the dark (night) theme. According to him, this technique will not work as an energy-saving technique on all devices - it all depends on the screen technology, but it will not be superfluous.

Or make it easier: create a profile in Windows with your own personalized settings, in which this will already be configured. Call it " There all these effects will be turned off..

Turn off all unnecessary.

Turn on airplane mode, switch battery life to power saving mode. Also check the programs running in the background and disable the programs you don't need..
