The computer memory fault light is always on, causing many users a headache. This tutorial aims to solve this problem. PHP editor Xiaoxin will introduce in detail the common reasons why the memory fault light is on and provide corresponding troubleshooting methods. By reading the following content, you will learn how to diagnose and repair memory failures and avoid serious consequences such as computer crashes or blue screens due to memory problems.
1.
First of all, confirm that the monitor is not faulty, then check whether the plug between the monitor and the graphics card is detached, and try to unplug and plug it in repeatedly.
2.
Open the main case (Note: For hardware safety reasons, please wash your hands or wear special anti-static gloves before turning on the computer) and confirm whether the fan of the independent graphics card is operating normally. Check whether the independent graphics card comes out of the slot (except for integrated graphics cards), then pull out the graphics card, wipe the metal tentacles of the graphics card clean with a soft cloth, and then insert it into the slot to see if it is normal.
1. There are three reasons for the car's inability to accelerate due to carbon deposits. First, carbon deposits appear in the valves, idle motor, intake duct, combustion chamber and spark plugs, etc., so the car will stall when it is idling. Phenomenon. The vehicle fault light is always on;
Solution: The most traditional disassembly method is to remove the engine from the car, and then clean it slowly with dish soap to remove carbon deposits. The advantage of this method is that it can be cleaned and has the best cleaning effect;
2. Driving on congested road sections. Cars driving on congested road sections for a long time, accelerating and decelerating for a while, will cause the car to show weakness when driving again. feeling, causing the vehicle fault light to stay on;
Solution: This is a normal phenomenon, just drive out of the congested road section;
3. Poor oil quality will cause the car to be unable to accelerate, which will affect the gasoline filter element and oil circuit. It may lead to poor fuel supply, resulting in inability to accelerate, and also affect the service life of the three-way catalytic converter in the exhaust system. If the three-way catalytic converter is clogged, it will also directly affect the acceleration of the vehicle and also cause Fuel consumption increases, resulting in inability to accelerate. The vehicle fault light is always on;
Solution: You need to go to a repair shop or 4S shop to find out the specific cause;
4. Sensor failure, such as oxygen sensor failure, causes the vehicle fault light to be on all the time;
Solution: Replace Oxygen Sensor.
Hello, the PLC fault light always on may be due to the following reasons:
1. Power failure: Check whether the power supply is working properly and ensure that the PLC has sufficient power supply.
2. Communication failure: Check whether the communication between the PLC and other devices is normal, and ensure that all connection lines are connected correctly.
3. Processor failure: Check whether the PLC's processor is working properly and ensure that the processor is not damaged or damaged.
4. Memory failure: Check whether the PLC memory is working properly and ensure that the memory is not damaged or damaged.
5. I/O module failure: Check whether the I/O module of the PLC is working properly and ensure that all I/O modules are correctly connected and not damaged.
If the above methods cannot solve the problem, it is recommended to contact the PLC supplier or technical support staff for further diagnosis and repair.
Press the del key when turning on the computer to enter the motherboard settings. The second to last power option in the first column has ERP support. Select enabled
First discharge the motherboard battery and restore the default BIOS settings. If the light no longer lights up after restoration, it means there is no problem with the motherboard integrated graphics card.
Tools: computer host.
1. Open the side cover of the host chassis and find the location of the motherboard.
2. Find the location of the battery on the motherboard. Most of the locations are near the CPU.
3. Gently push the buckle on the motherboard battery outward.
4. When pushed to the bottom, the battery will pop out automatically. Leave the battery for a few minutes, then put the battery back to turn on the phone.
The first is caused by sensor problems;
The second is caused by improper maintenance;
The third is caused by oil quality problems;
4. Caused by poor combustion of the mixed gas;
5. Caused by air intake problems . There are several main reasons why the engine check light comes on: 1. This is caused by a sensor problem. The sensors mentioned here mainly include water temperature sensor, crankshaft position sensor, air flow sensor, etc. If these sensors are damaged, resulting in poor contact or signal interruption, the car's electronic control unit will not be able to obtain accurate data from the engine, which will cause the engine to turn on the malfunction light.
The solution is as follows:
1) Turn off the main power, remove the bios battery from the motherboard, leave it for a while and then put it back.
2) Only one CPU (including fan), one memory, and one graphics card are reserved on the motherboard. Connect the power supply and monitor and turn it on to see if it can start.
3) If possible, add peripheral devices one by one to see which device causes this problem.
4）若还是不能开机，你手上有其他平台，可以将显卡，内存拿过去交叉测试一下。再不行就将主板带至服务中心检测维修。 造成这种情况的原因主要是计算机在启动时读取内存读取失败，因此导致计算机无法启动。如果还有其他问题就只能去咨询专业的维修人员了。
我的是五菱荣光v，17年上牌，18000公里左右，从18年开始亮发动机故障灯，换过氧传感器，又亮，一段时间又亮，换过上游传感器又亮，换了好几个了，都解决不了，现在还是亮故障灯，到底什么原因，到底去哪能修好，跪求大神帮助
发动机工作不平稳，直接影响汽车的动力性和经济性，以及乘客乘坐的舒适性，增加汽车污染物的排放等等
因此，当车辆出现发动机工作不稳时，要判别其故障的原因，使其恢复正常工作的方法。检查步骤如下：
1、应检查火花塞和分缸线。火花塞的间隙是否符合原厂技术标准，分缸线的电阻值是否也符合技术要求，如不符合需进行调整或更换。
2、需进行燃油压力系统的检测。检查燃油压力表和燃油压力表组件，连接油管和油表。起动发动机并使其进入怠速运转，燃油表读数应在270~320kpa范围内。若压力超出技术规格，则需要更换燃油压力调节器及燃油滤清器。
3、检查各缸喷气嘴。使发动机进入怠速运转，分别断开每一个喷油嘴插头，检查其怠速是否有变化，若断开每个气缸的喷油嘴，怠速降低基本相同，则说明喷油嘴工作均正常。当断开某一个喷油嘴时，发动机怠速及其稳定性均无变化，则需要测量喷油嘴插头的电阻值是否为10~13,如果不符合标准则更换喷油嘴。
当然还需要进行PGM－FI主继电器与插头连接点之间导线的检查，插头连接点与喷油嘴之间导线是否有破裂，连接不良等故障。
4、燃油泵及燃油泵电路检查。燃油泵的检查：拧下燃油箱盖，点火开关在 ON位置时，在燃油加注口可以听到油泵运转的声音，在正常工作情况下，当点火开关在 ON时，燃油泵应运转2秒钟。如果燃油泵不运转，首先检查油泵保险是否烧坏。检查PGM－FI主继电器与插头端子之间是否导通等等。
5、其次还要检查气缸的压力、进排气门的间隙、燃油蒸气控制电磁阀、EGR阀缸体工作情况、进气歧管是否漏气等等。
造成发动机工作不稳的原因很多，因此，出现问题后及时去售后挨个检查排除，才能准确找出故障原因和解决问题的方法
发动机有没有抖动或者油耗增多，有的话检查前氧传感器，没有的话检查后氧传感器或者。
