Generally speaking, the power of different brands, types and sizes of laptops are different, mainly depending on its CPU power, graphics card TGP and other hardware facilities. Below are some laptop power, which may vary depending on the configuration, for reference only.
| Laptop Brand | Power(watts) |
| Lenovo Flex 3 | 50w |
| Dell XPS 15 | 150w |
| Samsung Galaxy Book Go | 50w |
| Asus ROG Zephyrus 15 | 200w |
| MacBook Pro 16 | 100w |
First, find out the power of the laptop, you can find these data on the manufacturing label or manual. Secondly, calculate it according to the usage hours of the laptop. Power consumption = power * length of use
For example, if you run a 60w laptop for 6h in a day, it will consume 0.36kwh of power in that day.
However, this is just a rough estimate. Because the laptop will also consume some power when it is not running, it will be in a variety of situations. For example, shutdown mode, sleep mode, active mode, etc., in these modes will consume a certain amount of power.
The size of the screen: the size of the computer screen will directly affect your power consumption, the larger the size, the greater the power consumption, the shorter the time you can run.
Battery condition: If your laptop has been in use for too long, the battery is old, or the computer is used frequently, then your battery will be in poorer condition and may need to be recharged more often.
Usage environment: If you have to use it in a brightly lit area, the computer’s screen will need to be brighter, which will increase the power consumption. At the same time, the temperature of the computer will also rise, and more power will be needed to dissipate the heat.
External devices: Laptops connected to external hard drives, USB devices, etc. will also consume additional power, which will increase the overall power consumption of the laptop.
4.1 You can reduce power consumption by controlling the brightness of the screen. Reasonable control of the screen brightness, not only can reduce power consumption, but also to prevent high energy consumption when the heat generated to shorten the life of the laptop.
4.2 Disconnect all non-essential connections such as Bluetooth when the laptop is not in use to prevent extra power consumption.
4.3 Optimize some applications, strictly manage applications running in the background, close some applications in the background, and turn on the power-saving mode when necessary to reduce power consumption.
Yes. In sleep mode, the processor, hard disk and most other components of the laptop will be turned off, but the computer’s RAM (Random Access Memory) is still running, it will continue to consume power. Therefore, even if your laptop is in sleep mode, it will still consume some power.
Laptops come in a wide range of power, but most of the people use typically 65w laptops. Knowing roughly how much power it consumes will help you calculate your power consumption, so that you can understand your energy consumption and estimate your electricity bill, and also take some steps to reduce it.
