Laptops are cool because they put a lot of computer power into a small, easy-to-carry device. But this power needs energy, and when you do things that need a lot of power, like playing games or editing videos, it uses even more energy.
In this guide, we’ll check how much energy a laptop uses when it’s working hard. We’ll look at what affects how much energy your laptop needs and share some tips to help you use less energy.
To understand how much power a laptop uses, we need to think about things like how hard the CPU is working, how well it keeps cool, and its power settings. When the CPU is working hard, the power used can change based on things like how the laptop manages heat and adjusts its performance.
Choosing laptops that use less energy or using methods like undervolting (a way to use less power) can help you use less energy and be more eco-friendly.

1. Understanding Watts and Your Laptop
Let’s start by talking about watts. A watt is a way to measure how much electricity something uses. If a device has a high wattage, it means it uses more electricity.
Now, let’s think about this in terms of a laptop screen. When you use your laptop for things that need a lot of power, like editing videos, playing games, or doing tough math problems, the laptop’s CPU (which is like the brain of the computer) needs more electricity. So, the laptop uses more watts when doing these hard tasks.
2. How Many Watts Does a Laptop Use on High CPU Usage?
When you use a laptop and its CPU is working hard, it uses more power. Usually, a laptop uses between 20 to 50 watts when it’s plugged in. This amount can change depending on what you’re doing with the laptop. Over one day, this adds up to about 0.48 to 1.2 kilowatt-hours of electricity.
To figure out how much power it uses in a month, multiply the daily amount by the number of days. To save power, you might want to get a laptop that uses less energy and try to do fewer tasks that use up a lot of battery.
To know how many watts your HP laptop uses when the CPU is busy, you should look at a few different things:
Laptop Model and Specifications
High-performance laptops, which have powerful processors and special graphics cards, use more power than simpler laptops.
CPU Type and Speed
Even though modern CPUs are designed to be efficient, those with more cores and faster speeds use more power when working hard.
Screen Size and Resolution
Laptops with bigger screens and higher resolutions need more energy to light up all those extra pixels.
Software Workload
The kind of software you use also affects power use. Programs that need a lot of computer power, like video editors or games, make the CPU work harder, which means higher power use.
Power Management Settings
Laptops usually have different power settings. High-performance modes use more power to boost performance, which can drain the battery faster.
Estimating Wattage Usage
It’s hard to say exactly how many watts your laptop uses when it’s working hard, but here’s a rough idea:
- Basic Laptops: Around 30–50 watts.
- Mid-Range Laptops: About 40–60 watts.
- Gaming Laptops: Can be 100–200 watts or more, especially for intense games.
3. How to Find Out How Many Watts Your Laptop Uses
If you want to find out how many watts your laptop uses when it’s working hard, you can do a few things:
- Check the Manual
Look at your laptop’s manual or the manufacturer’s website. They might tell you how many watts it uses for different tasks. - Use Special Software
There are programs like HWMonitor or Open Hardware Monitor that can show you how many watts your laptop is using in real-time.
Ways to Save Energy
Even though using your laptop a lot will always use more energy, you can still save some:
- Change Power Settings
Most laptops let you choose how much power they use. If you don’t need high speed, you can set it to use less power. - Turn Down Screen Brightness
Your screen uses a lot of energy. Lowering the brightness can save power. - Close Unused Programs
If you’re not using a program, close it. Some programs keep using energy even if you’re not using them. - Undervolt (Advanced)
This is a more advanced method. If you’re good with computers, you might try undervolting your CPU to use less power, but it can be risky if you’re not sure how to do it.
Other Energy-Saving Tips
- Keep Your Laptop Cool
If your laptop gets too hot, it will use more power to cool down. Make sure it has good airflow. - Use a Cooling Pad
If you use your laptop for a long time, a cooling pad can help keep it cool and save power. - Choose Energy-Efficient Parts
If you’re buying a new laptop or upgrading, look for parts that use less energy.
FAQs
My Laptop Gets Hot During Intense Tasks. Does That Mean It’s Using More Power?
Yes, it does! When your laptop works really hard, like when you’re playing a game or running a big program, it needs more power. This extra power can make your laptop get hot. Good airflow is important to help keep it cool and prevent overheating.
Are Gaming Laptops Always Power Hungry?
Gaming laptops usually have powerful parts to run games smoothly. These parts use more power than regular laptops, which means they can use more electricity. But, new technology is making gaming laptops better at using power efficiently, so they don’t always use a lot.
How Can I Check My Laptop’s Power Usage in Real Time?
If you want to see how much power your laptop is using, you can try:
- Check the Manual: Look at your laptop’s manual or the manufacturer’s website to find out how much power it usually uses.
- Use Special Software: There are programs like HWMonitor or Open Hardware Monitor that show you how much power your laptop is using right now.
How Can I Find a Laptop That Uses Less Power?
Look for laptops with energy-efficient processors from brands like Intel or AMD. These processors are good at using less power while still performing well. Also, find laptops with features that adjust power usage based on what you’re doing, which helps save energy.
Summing Up
Knowing how many watts a laptop uses when it’s working hard helps you make smart choices. By using the tips given, you can make your laptop use less energy, keep the battery lasting longer, and maybe even save on electricity bills. The trick is to find the right balance between how well the laptop works and how much power it uses based on what you need.
