What is the power of the laptop? Does the laptop consume power?

Nowadays, there are more and more laptop users, and nowadays notebook computers are used more and more frequently, which leads to higher and higher notebook power. What is the Power Supply of the notebook ? Does the laptop consume power?

What is the power adaptor of the laptop?

The power of each laptop is different, generally around 60W-70W, but it is not practical. Laptop accessories are generally designed specifically for low power consumption, power is generally between 1/2 to 1/3 of desktop computers, or even lower, the Internet's power is even more do not talk about it. The power of the laptop alone is about 90w.

The power of the notebook computer is generally around 20W, which is related to the height of the screen, and is also related to the CPU. For example, the Centrino II generation saves power compared to the first generation. The power of the laptop is different during use. This depends on what you do on your laptop: whether you are surfing the Internet or watching a video with a CD-ROM, or using a mobile hard disk, and the brightness of the display. Automatic power management system, adjust your power at any time. The notebook power algorithm is that if the output voltage is 16 volts and the output current is 3.75 amps, then the notebook's power is 16x3.75=60.

Does the laptop consume power?

Usually typical laptop Power Supplies around 65W, 65W rated power is now calculated, 1000W * When / 65W = about 15 hours, which is about 15 hours of electricity. That is, the electricity consumption for one hour is about 0.07 degrees, and the conversion is 1.68 kWh a day .

How can a laptop save more power?

1. Use power management software: It's wise to use power management software in your laptop. They can significantly extend battery life . With different modes of power management, laptop battery life can be nearly 1 hour. difference. The power management software selects the balance between power consumption and performance by changing the screen brightness, processor speed, hard disk idle time, standby time, etc. during work, thereby providing system efficiency and reducing power consumption, thereby extending battery life. The purpose of time.

2, cooling and deceleration: reducing CPU power consumption is the most direct power-saving solution for manufacturers. Obviously, the CPU is one of the most power-hungry notebooks in the notebook. The current notebook products support the "down-conversion" in battery-powered mode since Intel SpeedStep technology.

3. Reasonable setting of screen brightness: The LCD screen of the notebook computer is a large power consumer. Reducing the screen brightness can effectively reduce power consumption and extend battery life. The dim environment does not require higher brightness. We can reduce it appropriately. it. Most laptops are designed with shortcut keys that directly adjust the brightness of the screen. Most of them use the Fn function key in combination with F6, F7 or similar keys. Some models can adjust the screen brightness through software. Of course, the most direct adjustment is based on BIOS, many models in the BIOS to adjust the screen brightness or battery power saving state, so that the notebook's inherent brightness range is locked within a certain interval, thus limiting the screen too bright and wasting more power.

4, remove the extra external equipment: unplug any device like PC card, USB, IEEE1394 and other interfaces, will help save power. For an external optical drive, when you don't need an optical drive, try to unplug it, because even if you are not using an optical drive, it will consume the same power. Also, if your machine has a built-in wireless WLAN module, turn it off when not in use.

5, learn to use sleep and standby mode: Many models now support sleep or standby mode, and even provide shortcut keys for users to use directly. But most users don't pay attention to this power-saving, practical and very useful mode for hardware. The standby mode will enter the false shutdown state, and the system will stop running, similar to the shutdown mode. However, the information you are currently running is stored in the memory, and a certain amount of power is maintained to maintain the memory without powering down, so there is no loss in the actual data in the memory, so that you can "instantly" resume to the point where you just hanged to continue working. The sleep mode is to write all the information in the current memory to the hard disk to save, and then the real shutdown, when the system starts again, then retrieve the memory data from the hard disk, and resume the breakpoint work. So hibernate is more power efficient than suspend, although it slows down slightly when restoring the system, but hibernate mode is much faster than a pure cold boot, and sleep mode saves hard disk boot time, saves power and protects hardware usage. life.

6. Disabling temporarily unused devices: Disabling some devices that are temporarily unused will reduce some useless power loss. For example, when we travel long distances on airplanes and trains, we may not need modems, network cards or some serial modules and built-in DVD and CD-ROM devices. You can try to turn them off so that the system won't Perform real-time queries and distribute power.

The above is what the small notebook brings to you? Does the laptop consume power? I believe that everyone has a basic understanding of the power of the notebook after reading this article.
