In the face of emergencies, we may need to shut down quickly, but what should we do if the computer motherboard does not have a power switch? PHP editor Xinyi will bring you a simple and convenient method to shut down the computer using a screwdriver. Although this method is relatively special, it can help us respond to emergencies quickly. Next, let's learn more about how to use a screwdriver to turn off your computer motherboard.
Find the F-PANEL interface on the motherboard, the PW pin on it, and use a screwdriver to short-circuit these two pins.
Find the motherboard manual, which contains the connection method of the switch. Usually in the lower right corner of the motherboard, the PWR SW mark is the power switch pin. After finding the power-on pin, use a screwdriver to connect the two pins together to power on. If there is no manual, there are small print instructions on the motherboard. You can compare it with the online print.
This method is to use a screwdriver to conduct electricity and connect the two pins of the chassis power button on the motherboard jumper. Generally, the motherboard has power marked on it. As long as you use a conductive thing to connect the two pins, the computer It will start. When you press the power supply of the chassis, you will connect the two pins on the motherboard.
Extended information:
Although the components on the motherboard are densely packed, they are not irregular. Manufacturers will draw simple regional logos and small letter logos on the motherboard. The slot area on the motherboard is usually written PANEL or F_PANEL. Due to the limited space of the motherboard, the words on it are very small, so you need to distinguish them carefully when wiring.
The two pins of the power switch are generally labeled as Power SW, PW, PWR, PWRBTN, POWER, ON/OFF, etc.;
The two pins of the reset switch are generally labeled as RESET SW , RESET, RES, RST, etc.;
The power light is generally labeled as PLED, PWR_LED, Power LED, etc.;
The hard disk light is generally labeled as HDLED, HD, HDD LED, etc.
The reason why the motherboard is burned may be due to defects in circuit design or manufacturing, overvoltage, overcurrent, short circuit and other electrical problems, or it may be due to overheating or aging, resulting in damage to electronic components. In addition, improper use (such as frequent power outages, plugging and unplugging cables, etc.), dust, moisture entering the motherboard, etc. can also cause the motherboard to burn. It is recommended that users pay attention to protecting the motherboard when using computers to avoid burns caused by human factors.
The specific solution steps are as follows:
1. Turn over the back and remove the battery first.
2. Remove the screws on the back panel and take off the cover.
3. Remove the memory.
4. Remove the hard drive. Lift the hard drive and pull it back to remove it.
5. When removing the optical drive, first remove the screws and then push the iron piece outward to remove the optical drive.
6. Remove all the screws and cables visible on the back, and unplug the data cable next to the optical drive.
7. Unplug the wireless network card cable and remove the network card.
8. Be careful not to forget to remove the screws hidden under the hard drive.
9. After removing the screws and cables, turn over to the front and take out the keyboard. There are small clips at the ESC key, F4, F8, F12, TAB, and PGUP. Use tools to push them up one by one before taking out the keyboard. .
10. When opening the keyboard, pay attention to the cable underneath. Do not pull it hard. Gently lift the clip upwards and it will come out.
11. Remove the screws and cables under the keyboard.
12. Do not use iron objects to pry open the C surface, which will easily crack. You can use a card board or nails to open it slowly.
13. When taking out surface C, pay attention to see if there are any wires or screws connected.
14. Unplug the data cable, cable arrangement, and remove the screws.
15. Remove the motherboard.
16. Turn on the fan to facilitate dust cleaning.
17. It is best not to dismantle the copper pipe when cleaning the dust, as this will cause the computer to work abnormally. The principle of disassembly is to observe before taking action. Tighten the screws diagonally. Never use non-professional tools to disassemble the machine.
18. Finally, install the machine carefully according to the disassembly steps. Be careful not to drop parts. Check after installation and start the test.
This depends on the situation, such as being flooded or struck by lightning, etc. If it is not broken with just use as mentioned above, there will be no problem. Ask: None of the above The situation happened. It was just over a year after I bought it, and it suddenly became like this... Answer: It should be fine. If you are still worried, you can connect the hard drive to another computer and use HDtune software to check. Question: The hard drive is new. , make sure there is no problem.
The computer repairman said that the motherboard is broken. Answer: The motherboard can only be repaired during the warranty period. You can try to reinstall the system first, and then consider the hardware problem! If the motherboard is burned out, there is a certain chance that the hard drive will also fail. But not high. Because the only thing connecting your hard drive to the motherboard is the signal line. harddisk. The power supply depends on. Power supply. Then the power supply also has protection functions. dgjq is therefore not necessarily
1. First unplug all the lines at the back of the host, then unscrew the two large screws next to it, and open the back cover of the chassis; 2. Remove the memory, forcefully remove the locks at both ends of the memory module, and push upward Pull out the memory module; 3. Remove the hard drive, unplug the two wires of the hard drive, and unscrew the screws that fix the hard drive; 4. Remove the graphics card, unplug the lock in the lower right corner, unscrew the screws, and pull it out with force.
If the battery on the motherboard is not replaced, it will have an impact on the computer: BIOS information, such as hardware information, time, etc., cannot be saved; if you keep putting it off, there will be no serious consequences. The maximum boot time will be inaccurate. , the motherboard battery of my computer is also dead. It has been 2 and a half years old. There will be no big consequences, but the time is often inaccurate. Will the settings in the BIOS be lost? It’s just that the BOSS settings cannot be saved for a long time, and the system time Similarly, a small number of motherboards may not be able to boot if the battery is out of power, but generally the system time is inaccurate and the BIOS settings are lost. Those batteries are not very expensive and are best replaced. It's completely fine. It's just that you need to press F1 every time you turn on the computer and the time starts from 0:00. It doesn't have any impact. You may have to press F1 when turning on the computer. This is a typical motherboard battery discharge! It's okay. At most, it's just that the time is wrong. It's best to change it. The time is reset and the BIOS is not saved. The BIOS battery is dead and the information in it cannot be saved. Similar to mobile phones, the motherboards below the NOKIA 3 series do not have batteries, so After removing the battery, you need to reset the time. The 3 series uses capacitors, which can last for more than 10 seconds. Series 3 and above have batteries, which can be used to remove the battery for a long time. Computers are more complicated. The information saved in the CMOS of the computer includes system time, CPU overclocking settings, and memory. Overclocking settings, startup mode (hard disk, optical drive, floppy drive, network, etc.) Boot mode (keyboard boot, automatic boot, etc.) BIOS password, fan revolutions, etc. There are some small differences between motherboards of various brands. Generally speaking It doesn't matter, it's just that the time in the computer is inaccurate. In fact, the problem is not very serious, but the solution is very simple. Just replace it. It only costs four or five yuan. If the time in the computer is inaccurate, the motherboard lithium battery is out of power. Turn on the computer and enter the default settings, and the F1 prompt will appear. The time is not accurate, and it may cause some anti-virus software to fail or other software to fail. It is recommended to buy one when you come back to change your career. It is very cheap at only one or two yuan each. There won't be any major problems. At most, the BIOS can be restored to its original state
