Why does the laptop turn on automatically when turned off

The wireless network card is set to power on automatically there.

The computer display will return to normal for a while, and it will turn off by itself for a while", the reason is the power management mode of the system.

1. Each version of the Windows operating system has a "power management mode" setting, which is based on three considerations, on the one hand, from the consideration of energy saving, on the other hand, it is to let the display get a reasonable "rest", and then to protect user privacy (not to let the information on the user's screen be exposed to others around for too long). Bucket shouts round.

2. Enter the power management mode in the XP system, right-click on the blank space of the desktop, click the drop-down box to select "Properties", select "Screensaver" and "Power" in the pop-up window, and then pop up.

If the XP system user does not specify this time, then the default setting is to turn off the monitor for 20 minutes when powered on, if a battery-powered laptop is used.

The monitor is turned off after 5 minutes. This means that if the user has not used the mouse or keyboard for 20 minutes, the system will think that the user is not with the computer, and it will automatically turn off the screen.

3. Win7 system, the higher version of the system is similar. First of all, go to the "Control Panel", click "Power Options", click the corresponding "Change Plan Settings" according to your needs, and then you will see the time when the system turns off the monitor by default. Another way is to right-click on the blank desktop and select "Show", you can also go to the Power Tube option.

<> Windows turns off the display when the user is not operating for a long time, which is a very user-friendly setting. If the user wants the monitor to be on all the time, they can also select "Never" in the "Turn off the display" option, which means never turn off the display.

Recently, a friend asked me that his computer boots slowly, super slow, it takes a long time to enter the system desktop, I didn't care at the time, today I made an appointment to play lol together, but I opened the computer at home and smoked a cigarette before he went online, casually asked: "Why is the online so slow?" ”。

He sent a **, saying that there is always a string of dots to boot up... It takes a few minutes and is very annoying.

I understood at a glance,My friend's machine is a second-hand machine received in an Internet café some time ago,The picture above is that the network card is started,The network card is looking for server IP information。 Internet cafes are all using a beamless Wu disk system, the local machine does not have a hard disk, and the system package in the server must be read through the network when it is booted up. If you have a hard disk, you don't need this function, just turn the network card on and off.

The motherboard here is ASUS, supports Chinese interface, select the advanced options inside the realtek pxe oprom, press enter, close, and then press f10 to save and exit.

There are also some old-fashioned motherboards with the same settings for the English interface, and I found a few on the Internet for your reference:

First of all, boot the keyboard and continuously hit the DEL or F1 button on the keyboard to enter the BIOS, select the "Onboard Device" in "Integrated Pripharals", set the "LAN Boot ROM" striker to "disabled", and finally press F10 to save the wisdom and exit, as shown in the following figure:

Two more: Lenovo models first boot up and continuously hit the F1 button on the keyboard, enter the BIOS, click the "Devices" option, and then click "Network Setup" to enter, change the "PXE Boot Agent" to "Disabled", press F10 to save and exit, as shown in the following figure:

There are also some motherboards to press F1 to enter the BIOS interface when booting up, click on the "Advanced" option, you can see the option of "Onboard Device Configuration", click on the option to enter, you will see the option named "PXE Boot ROM", set this item to "disabled", as shown in the figure:

ThinkPad models turn on and continuously tap the F1 button on the keyboard to select"config"option, the bottom clicks"network"option, once entered, will be"ethernet lan option rom"options, select"disabled"Can.

Roughly like this, don't forget to press F10 to save and exit after setting it up. Attentive friends will find a few keywords: pxe, lan, rom, disabled, remember these keywords under the BIOS to set the network card boot is much simpler.
