My computer turns on automatically at 2 o clock every night, and I would like to ask the masters

The motherboard BIOS is set to auto-boot time, or Wake-on-LAN! If you don't set up automatic boot, it may be caused by a virus, you can reinstall the system, or remove the Trojan!

Start by going to the "CMOS setup" program (most motherboards are entered by pressing the del key when the computer boots up); Then move the light bar over the "Power Management Setup" option and press Enter to enter its submenu; Then set the "resume by alarm" item to "disabled", and that's it

Some motherboards are selected after entering the "Power Management Setup" option and selecting "Wake Up Events".", enter, and there is an item in it that says "power on by alam.""and change it to "disabled".

1.Brother, if you have such a failure, it is very likely that the quality of the power supply is a problem, and the construction is not good, and it cannot be shut down, which is the biggest reason.

2.It's just a mistake in the BIOS, you can take a look.

3.The switching power was turned off when the power was turned off.

Did you enable the task scheduler?

Take down your ** cable or network cable! Give it a try!!

Summary. 1: Check whether the computer software is set to turn on at 24 o'clock, if it is set to close.

2: Check whether the BIOS is set to boot on time.

Method: My computer will automatically turn on at 12 o'clock every night, what should I do?

1: Check whether the computer software is set to turn on at 24 o'clock, if it is set to close. 2: Check whether the BIOS is set to boot on time. Method:

A: Select the "Power" option in the main interface of BIOS settings to enter the power management window. b：

By default, the Automatic Power Up option is turned off, move the cursor to this item, and use the "Pagedown" key to change "disabled" to "enabled". C: The "Automatic Power Up" option will pop up a menu with three options:

disabled, every day, and by date", which means "forbidden, daily, and specified day". For office workers, we recommend the second option, where a date and time setting pops up. d：

See if it's 24 o'clock if it's closed. 3: Turning off the power after the computer is used can prevent this from happening.

1. Power supply problems;

2. BIOS setting problems;

3. Wake-up function;

Power supply problem: It is mainly manifested in the poor grounding system, which is divided into poor mains grounding and chassis grounding;

The solution is as follows: connect the power strip to the computer;

BIOS Setup Issue: When the timer boot function is set to Enabled, the machine will automatically power on at a certain time on a set date. In addition, some motherboards have an auto-turn on function setting in the BIOS settings of the motherboard, and if this function is selected, the machine will automatically turn on when the power is on.

There are two types of grounding:

1. Place of work, 2. Protected place.

1. Check the BIOS settings and set the Restore AC Power Loss of the Power Management Setup in the BIOS to Disabled.

2. If the above method does not work, continue to set PM Control by APM of Power Management Setup to Yes in BIOS.

CMOS chips are related as follows:

First, go to the main interface of CMOS settings, select [Power Management Setup], and then select [PWR Lost Resume State], which has three options.

If you select the [Keep Off] item, it means that the computer will not automatically start when the call comes back after the power is off.

If you select "Turn On", it means that the computer will automatically start up when a call comes in after a power failure.

If [Last State] is selected, it means that when a call comes back after a power outage, the computer will return to the state of the computer before the power outage. If the computer is turned on before the power is off, it will automatically turn on after the call comes. If the computer is in a shutdown state before the power is off, the computer will not automatically turn on after the call.

I would like to add that it is caused by viruses (large categories). Nowadays, cyber security is becoming more and more serious, and even preventive measures are improving, which is important and I am applying to be classified as Category 4. Computer security is becoming more and more important today.

Wake-up function: Right-click "Computer - Properties--- Hardware --- Device Manager - Network Adapter" and then double-click "Network Adapter" - the found network card, double-click, in the "Advanced" column, set the "Wake-up" function to disabled.

Me too! I was playing with my phone and suddenly turned it on, and when I saw it at eleven fifty-eight, I was scared to death, so I unplugged it directly
