Computer time display error and processing of the motherboard battery failureThe computer time error and motherboard battery failure in daily work are invalid. Take the XP system as an example (shown in the figure): Double-click the time in the lower right corner of the computer → enter the date and time of the attribute window → modify the time; you can go online, you can: choose the Internet time → Check Synchronization and Server → Update Now → Click Apply → * OK.
If there is a time error, or the time is N years ago, it may be a computer battery that is not *, or the motherboard BIOS problem.
You can set time on the BIOS, + or - or adjust time, factory setting, then F10 restart, normal, then shut down for 5 minutes, then restart, check the time whether there is abnormality.
If there is still a problem, it is the problem of the battery. You can choose to change battery electronics, pay attention to positive and disassembly: After removing the battery, you will be prepared in the original position in this battery holder, and you should pay attention to the battery. Anti-contained, it can't be safe.
Method for discharging the motherboard battery
1. Use CMOS discharge jumper
For most motherboards, CAHOS discharge jumpers are designed to facilitate user discharge operation, which is * commonly used AHOS discharge method (the method of the following methods 2, 3, 4 and small knots are basically not used. The discharge jumper is typically three-needle, located near the motherboard CMOS battery socket, and is attached with a battery discharge instruction (some of which are two-needle, such as the ASRock motherboard, also near the Motherboard CMOS battery, there is a CLRCMOS logo, two-pin direct electrical conductive object Connect a two seconds, that is, the discharge is successful).
In the default state of the motherboard, the jumper cap is connected to the pin identified as "1" and "2", and it can be known from the discharge instructions, which is the normal usage state.
To discharging using this jumper, first remove the jumper cap from "1" and "2" with a camera or other tool, and then set it on the pin identified as "2" and "3". They are connected, and it can be found at this time by the discharge instructions.
"Clear CMOS", that is, CMOS (as shown below). After a short (one second, long-point does not matter), you can clear the various manual settings in the BIOS in the BIOS, while restoring the default settings when the motherboard is shipped.
After the CMOS is discharged, you need to remove the jumper cap by "2" and "3" pins, and then restore it to its original
"1" and "2" pins. Note that if the jumper cap is not returned to the Nornal state, the computer cannot be started and the alarm prompt.
Wuxi Huizhong is a company specializing in the production of OPZS tube-type batteries. The OPZS model is complete, the price is low, the quality is good, the after-sales service is timely, and the delivery is timely.
The project will invest 12 billion yuan in Danzao Town in Nanhai District, including 12 billion yuan, including total investment of 1 billion yuan in the world's only hydrogen power vehicle R & D center. The whole vehicle production project is divided into two constructions, and the production models include pure electric and hydrogen fuel cell bikes, special vehicles, logistics vehicles, passenger cars, etc., annual production of 160,000 vehicles, the total output value of the completion of the production of 40 billion yuan. This means that the South China Sea will achieve "transition" manufacturing from traditional car machines to new energy vehicles. New energy vehicles are recognized at home and abroad. Strategic emerging industries. From the "13th Five-Year Plan" of the Development of Advanced Manufacturing Development, Guangdong Province has been placed in the Xi'an West Coast.
2. Remove the CMOS battery
I believe there are many users who have encountered the following: I have to discharge CMOS, but on the motherboard (such as the ASUS motherboard) can't find the Jumper of the CHOS discharge, what should I do? At this point, the CMOS power battery can be used to achieve the purpose of discharge. Because the power supply of the BIOS is supplied by the CMOS battery, the battery is removed to cut off the BIOS power supply, so that the parameters set in the BIOS are cleared.
Find the CWOS battery socket on the motherboard, then use the buckle pressure on the socket to get the power battery, at which point the CNOS battery will automatically pop up and take the battery carefully.
Then turn on the host power supply to start the computer, the screen will prompt the data in the BIOS to be cleared, and you need to enter the BIOS to reset. In this way, the CMOS discharge can be successfully discharged.
