If you decide to use a laptop rather than a desktop, the odds are that you need your computer to be portable.
You might be wondering, how many watts does a laptop use?
But this will come with some considerations, including the laptop's battery life.
Determining how much power your laptop will consume should be one of your top priorities. If you’re looking to take your laptop on long journeys or to places where you can’t plug it in, having a long-lasting battery is essential.
To figure out your battery’s life, you need to know how many watts your laptop will use.
Your computer’s wattage – how many watts it uses – is the measurement of how much power it needs. The more watts your laptop uses, the quicker its battery will drain.
There is no single answer to how many watts a laptop uses. While most need anywhere between 20 and 100 watts per hour, this can increase to 180 watts per hour for some laptops.
These variations often reflect the reason for the laptop’s use. Different needs require different hardware and usage. If you are a serious gamer or plan on using programs that need high-quality visuals, you can expect your laptop to consume more watts.
Your laptop’s adapter is the power supply that plugs into the main system. The larger your laptop, the more powerful its adapter will need to be.
Bear this in mind if you are looking to upgrade your laptop. Make sure that anything you add is compatible with your laptop’s power supply
Your laptop’s central processing unit (CPU) is one of its key components and works as the brain of the computer. It’s the part that runs the programs and translates your actions into reality—whether that’s searching, designing a house, or playing a fast-action video game.
But not all CPUs are created equal. Higher quality CPUs are more efficient and use less power.
The graphics card controls the quality of your laptop’s display. If all you need your laptop for is browsing the internet and running spreadsheets, then it will be fine to run with a lower grade graphics card.
But if you plan on gaming or running computer aided-design (CAD) programs, you should invest in a better graphics card. A better card will improve visuals and help the computer run more smoothly but requires a higher wattage.
Your laptop’s screen is the biggest drain on its battery. The larger your screen displays, the more battery it uses.
A 16-inch laptop screen generally uses around 60 watts per hour. However, if you decide to choose a larger model, your wattage can increase to up to 100 watts per hour.
A laptop can’t function without the hardware mentioned. However, each brand and model will have its own specifications.
The easiest way to get a rough estimate of how many watts does a laptop us is to check its adapter. The adapter will tell you the maximum power input your laptop can accommodate. With a bit of effort, you can determine a more accurate figure of it's power consumption.
Check the components – The specifications of your laptop components are available on their respective websites. However, adding these together will not give you your laptop’s exact wattage or power consumption. But, inputting the figures onto an online power consumption calculator will yield exactly how much power your laptop uses.
Electricity usage monitor – The easiest way to find out your laptop’s wattage is to use an electricity usage monitor. Plug your laptop into one of these devices for a real-time calculation of how many watts your laptop uses and to determine the power consumption.
Knowing how much power your laptop uses is useful information, but knowing how to reduce it's electricity consumption it is just as important.
With a few small tweaks, you can increase how long your battery lasts and how much power does a laptop use.
Your laptop’s wattage is not just affected by the size of its screen. The brighter your screen, the more energy it will use. Check your laptop’s settings to find out how to decrease its brightness.
Buy a cooling pad—your laptop’s CPU and graphics card run more efficiently at lower temperatures, and so use less battery power.
Use the right laptop for the job—it might be tempting to buy a high-end gaming laptop, but it would be a waste of watts and money if you only need it for writing essays.
Invest in the correct hardware. Electricity costs money – using high-quality and more efficient hardware will save you money in the long run.
Being able to carry your computer around with you is one of the best things about having a laptop.
A gaming laptop will use more watts and electricity than a simple everyday laptop does. If you are planning on getting a gaming laptop, get ready that it will not last that long on just the battery itself.
But it becomes useless if you constantly find yourself running out of battery.
Taking time to research your laptop’s specifications will help you to make the most out of your laptop’s battery.
I'm a tech geek from Hungary. Latest laptops? I got em. I love testing and breaking things, although most of the time I fail putting them together, but that's another story...
