Laptop Battery Backup -Types, Hours and Tips
We've all been through this. You're on a date, traveling, or in a classroom and discover to your horror that your laptop is nearly dead. You may have forgotten the power adapter. The outlet may not be available. Somehow the battery is almost empty and there is still more to be done. However, hope was not lost. There are things you can do to free up more time on that low battery, so you can meet deadlines or reply to important emails before it's too late.
Some of these techniques are designed for when you need to stretch the battery at this point, while others are a precaution that is best used before the battery runs out. There is some overlap between the short-term and long-term strategies which we will outline below, but even if they are the same size, the reasons can be different.
Short Term Strategy for Stretching the Battery
If you are currently in a difficult location, you can extend battery life right away. Neither of these actions increases the amount of charge left in the battery, but rather reduces the power consumption of the laptop so you can save a few more minutes before the battery runs out. The name of the game in this case is energy use and you should minimize it.
1. Turn on the Battery Saving Function on Your Laptop or in Eco Mode
Most battery saver or eco mode is designed for these types of circumstances and includes several automatic changes to help extend battery life - many of the same changes we'll be making here. This saved profile adjusts the settings on your laptop and puts components into power saving mode so you can distribute the rest of your juice a little longer.
After you activate the auto-save tool, there are still many steps to be taken to get better performance. To do this, you need to turn off unnecessary devices, adjust settings to reduce power consumption, disable unwanted apps and processes, and adjust your activity so that less power is used.
Disable Unused Devices and Ports
The easiest way to reduce energy consumption is to simply turn it off. Every component of your laptop needs electricity to function. However, this doesn't mean that you need to save power for all of these components all the time. First, turn off all unnecessary peripheral devices (eg USB mouse or external devices) and turn off the biggest power supplies such as WLAN and Bluetooth radios, graphics processors, and unused optical drives.
WARNING: Before turning off any component or device, ensure that the device is unused and unimportant to continue using the laptop. For example, you don't want to disable the hard drive where the operating system resides or the processor that runs the entire laptop. Only disable devices that you can turn off.
To disable unused devices on Windows systems, open your system's Control Panel, and search for Device Manager. In the device manager, each component is grouped by category. For example, network adapters often include LAN adapters that provide Ethernet and Wi-Fi connectivity for wireless networks.
