How Do I Reduce The Power Consumption Of My Laptop Window 7?

The autonomy of laptops has increased substantially over the last few years. Still, prolonged work sessions will drain their batteries if we don’t take the proper precautions.

Applying these tricks will help you prolong your laptop’s battery duration, which allow you to decide when your laptop screen or the hard disk drive will turn off.

You can use many tricks to extend your battery life and continue working for more extended periods without the need to connect the equipment to the electrical network. Some of them focus on disabling the adapters that provide connectivity and disconnecting external devices when you are not using them. We suggest making changes related to the software that will also lead to higher performance.

Tip 1: Don’t Suspend It; Better Hybridize It

Don’t Suspend It, Better Hybridize It

Keep in mind that when you are not going to use your laptop for a considerable period. It’s preferable to configure it to go into hibernation rather than sleep. This is because the first option saves the current state of the computer to disk and turns it off completely. While if you use the second, both the CPU and memory will maintain some activities.

Tip 2: Disable Connectivity

Practically all new invoice laptops integrate a Wi-Fi device that connects to a network. While this will be essential for you to navigate, download email, and carry out other necessary actions, in all probability, there will be times when we will focus on writing documents and performing other tasks.

At this point, keep in mind that even if you aren’t using your wireless connection, it will be consuming a substantial amount of energy. Consequently, turn it off whenever possible using the tools that laptops usually include for this purpose, or remove the peripheral if you are using an external one.

If you need to consult a website frequently, to save even more, we suggest that you download it to your laptop hard drive while it remains connected to the electrical network. Later, when you need to consult it, you will be able to navigate through it in offline mode. In this case, HTTrack Website Copier 3.4 constitutes an excellent solution that is distributed as free software.

The same applies to email: if you need to continually refer to your message history, using an email client such as Mozilla Thunderbird 12 will allow you to do so without the permanent connection requirement working with webmail.

Laptops often also offer connectivity via Bluetooth, infrared, and other routes that also cost additional energy. Since there is no point in keeping them always open, dispense with them when they are not essential.

Tip 3: No Services Or Applications

Disabling programs and the most spectacular features of Windows will prolong the life of your battery. The same is true for system sounds, which you can mute by going into the Hardware and Sound section of the Control Panel.

On the other hand, try to keep all the programs that you aren’t using closed. Keeping applications such as Live Messenger or Dropbox running in the background consumes resources that result in a slow but constant drain of energy. Thus, as long as the software allows it, disable the option to start automatically every time the system starts.

If this is not the case, keep in mind that you can disable its automatic start by running the MsConfig application through the search box in your Start menu and accessing the Windows Start tab. However, while turning off application updaters and other heavy software will also result in smoother overall operation, keep in mind that some modules that start automatically may be essential.

Thus, the same can be said for system services, which you can access by typing Services in the Start menu box. Although many of them are essential, turning off Windows search and others that are expendable will prolong your battery life. The Black Viper website will offer you detailed lists of all of them and will illustrate their functions, both in Window 7 and in its version with Service Pack 1.

Tip 4: Remove The Hardware

Remove The Hardware

Another source of consumption is external devices with USB connectivity. Since the computer itself powers removable disk drives, MP3 players, USB microphones, and other peripherals, they will drain your battery little by little if you keep them connected, even if you don’t use them.

So, if you need to resort to data on a pen drive intermittently, you should copy it to the hard drive and extract it from its port. The same can be said for CD and DVD drives: reading data from them increases energy waste, so instead of keeping the disc on its tray, duplicate its contents in a folder on the hard drive and remove it.

If the CD / DVD drive is external, unplug it. On the other hand, using the touchpad may not be as comfortable as using a mouse, but keep in mind that even when you’re not sliding it or pressing its buttons, keep an eye out for any signals and therefore consume power.  If you have an old laptop and use PCMCIA sound cards and other devices that make use of these types of slots, remove them as well whenever you are not using them. The simple fact of keeping them inserted costs the battery.

Tip 5: RAM And Hard Disk

RAM And Hard Disk

Most applications running on your PC uses RAM. Thus,more applications you open on it, slower the speed of work done by the RAM. The most immediate disadvantage of this feature is that operations are completed less quickly. It should also be added that they consume more energy. If prolonging your laptop’s autonomy is a priority for you, consider adding RAM memory. You should also keep all applications and programs run at the background closed.

Regarding the hard disk, consider one of these laptop for accounting professionals that uses SSD technology to hold your company files. They are not only much faster but also contribute to savings in the energy field. So if you plan to update your hardware, they can mean the ideal complement.

If you are going to continue working with a conventional disk, defragment it regularly. Think that if you have been deleting and adding files for a long time, in all probability the information will be scattered throughout the unit, and when it comes to reading it Windows will have to track each part of the files until it finds them all, which translates into higher energy expenditure.  Make it easier for yourself to work and take advantage of the fact that you have the machine connected to the electrical network, go-to equipment, and click with the right mouse button on the disk in question. In the contextual menu that will be displayed, choose Properties, and then go to the Tools tab. From there, you can defragment the unit.

Does A Laptop Consume Less Energy Than A PC?

Conserving energy is suitable for both the environment and your wallet. Selecting the right equipment can lower your energy bill if the laptop energy is efficient. Laptops are designed to consume less power than desktop computers and to use electricity more efficiently. Using any of these Laptops for Cameo 3 instead of a desktop computer will reduce the amount of energy you consume on a daily basis.

1. Energy Supply

Energy Supply

Desktop power supplies are capable of delivering hundreds of watts of output power but typically use around 150 watts during moderate activities. A laptop typically draws 30 to 40 watts of power during reasonable use and more when the battery is charging. Laptops are also capable of working in a “low power” mode, which reduces the amount of power a laptop uses and is designed to preserve battery life.

2. Displays


The power consumption of a laptop is used to power the computer and its LCD screen. Most desktop computers do not have a built-in display, which means that your LCD or CRT monitor has its own power supply, increasing the amount of power used when the computer is active.

3. Processors


Laptops use “mobile” CPUs and processors specially designed by manufacturers to use lower amounts of power than their desktop counterparts. Your laptop mobile CPUs need to be energy efficient in order to extend the battery life of a laptop; desktop ones have a constant flow of energy. The energy efficiency of the mobile processors is not as powerful as a standard desktop processor. Applications that require large amounts of system resources may run slower on a laptop because of this limitation.

4. Components

Desktop computers are expandable and can contain more components than a laptop. High-performance desktops can hold multiple hard drives and multiple graphics cards. Thereby increasing the amount of power they consume. The more parts you install inside a desktop computer, the more electricty power it will consume. If your notebook computers contain a fixed number of components, then they are not as prone to modification as desktop computers, but the limited expandability of notebook computers limits the amount of power-consuming components that can be installed.

5. Uninterruptible Power Supply (UPS)

Uninterruptible Power Supply

Your laptop battery allows it to run continuously in areas where power outages and spikes are frequent. Powering a desktop computer requires the use of an uninterruptible power supply. UPS backups can only power a desktop computer for a short time and consume large amounts of power when charging.
