The computer always starts up after a long time after it is powered on, why?

Optimize it with Master Lu, and optimize it when 360 boots up. Anything else can only be replaced with hardware, and there is no special effect method.

The computer host is connected to the power supply and cannot be turned on immediately, at least it means that there is a problem with the capacitance of your computer motherboard, or there is a problem with the capacitor in the computer power supply, in fact, the metaphor on the first floor is very vivid, but it is not detailed, I will add:

The capacitor on the power supply line of the host power supply or the computer motherboard, if it cannot be charged and discharged at a normal speed, it will lead to such a problem, capacitor energy storage needs a process, the normal capacitor process is very fast, but the capacitor is aging or faulty, this process is very slow, it is recommended that the landlord open the chassis to see if there is a bulging capacitor on the motherboard, the top of the capacitor is flat, and the bulge can be found with the naked eye, but if the host power supply capacitor is faulty, you need to disassemble the power supply.

If you don't know what a capacitor is, it's like a stubby cylindrical firecracker with two legs.

The host power supply is not enough and needs to be replaced.

If you don't have power for a long time, the capacitor is empty, and you think that the reservoir needs to be filled with water to push the water wheel.

Very vividly described as hope.

There are three cases:

1. Power supply problems.

2. BIOS setting problem.

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.

Secondly, I want to correct a friend just now, the quality of the power supply is not good, it will cause a crash, and it will not restart.

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.

Refer to the following method for BIOS settings.

The settings of your machine can be checked by following the steps below.

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.

Note that this is not the case for individual BIOS versions, please refer to the specific BIOS manual.

This is related to everyone's CMOS chip.

There are also the following: first enter 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 [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 although it can also be classified as a wake-up function, I would like to mention it separately. That's caused by viruses. Cybersecurity is becoming more and more severe, and even if prevention measures are improving, they are not as fast as they are.

I think this is important and the application falls into the fourth category. Computer security is becoming more and more important today.

What is the understanding of workplaces and protected areas, is this question okay now???

The working place is a virtual land, and the protected land is the earth Simply put, the ground on the chassis is the working place, and the protected land is the earth.

Wake-up function: Check if your network card has a "wake-up" function? You can right-click on "My Computer --- Properties--- Hardware Device Manager - Network Adapters" and then double-click on "Network Adapters" - find your network card, double-click on it, and in the "Advanced" section, set the "Wake-up" function to disabled.

Is it set up somewhere?

1. Reason: If you plug in the power supply for a period of time to turn on, this is because there is a problem with one (or some) capacitors in the power supply part circuit, so it cannot respond immediately and the current cannot be output instantly.

2. Suggestion: go to the after-sales service for maintenance or replace a power supply.

Related principle: a. The mains power is 220V alternating current, and the computer needs direct current to work, and the role of the computer's power supply is to convert the alternating current into direct current for the computer. Capacitors play a central role in the smooth operation of the entire system in this process.

b. The capacitor itself has the function of charging and discharging, and the situation you mentioned is because of some reasons that cause the impedance of the capacitor to become larger, which makes the charging and discharging efficiency of the capacitor decrease and the charging and discharging time becomes longer, so it will be so slow to enter the normal working state.

How long is it every once in a while, does your computer start with a "dripping" sound before the screen turns on, if so, it is normal (memory self-test); It's normal to display a piece of English when you boot up (hard disk self-test program),If you enter very slowly,More than 2 minutes this you can optimize your startup items,360,Computer Manager and other programs are optimized with their own startup items,If more than 5 minutes, then maybe your hard disk is a little problematic,You can take it to the physical store to test the hard disk。
