The laptop power adapter is the basis for the normal operation of the laptop. If there is a problem with the power adapter, the battery will not charge properly and the interface will be in poor contact. What if you have a laptop power adapter problem?
2. If the power supply or battery connector is good, use a multimeter to measure the output voltage of the power adapter or battery. Mainly check whether the output voltage is stable and whether the actual output voltage value matches the nominal voltage of the power supply. If the output is unstable or the actual output voltage is very different from the product specification, replace the damaged power adapter or battery.
3. If the above detection steps are normal, you can infer that the problem is on the notebook power board or motherboard. Open the notebook case and check that the power board is in good contact with the motherboard.
4. If the power board and battery are in good contact. Then use the replacement method commonly used by DIY to check whether the power board is normal. If it is not normal, replace it.
5. If the above method is used, confirm that the power supply board and battery are normal. It can be inferred that the notebook motherboard or other main components are damaged (such as a boot circuit problem), and the motherboard can be repaired or replaced at this time.
2. Check if there is any power between the power adapter and the computer. This can be indicated by the indicator light of the notebook. When the power is charged to the notebook, the charging indicator will light up. Otherwise, it will not light up. Or try to find a power adapter exchange of the same brand. Use your power adapter to hold the other party's notebook. If the other computer is working properly, your power adapter is fine. Otherwise, there may be a problem with your power adapter. If your computer's power adapter is plugged into your computer and your computer is working properly and your own power adapter is not working properly, then your power adapter has a problem.
3. Observe the change of the indicator light of the computer. If you plug in the power adapter, you can see that the charging indicator lights up and off, there is no time to go, then there is a problem with the power adapter interface in the notebook, generally the inside of the cable is broken, the board is aging, welding Drop and other reasons. This is called a virtual soldering phenomenon. This situation can only be repaired by professionals.
The above is the cause of the laptop power adapter problem and how to get it. If the problem is serious, you can try to change the power adapter. You can browse our user-friendly online store oriccabattery.co.uk. To provide a cheap and high quality notebook adapter for your notebook, remember to search for the applicable model!
First, testing:
1. First, check whether the power adapter or laptop battery is in good contact by gently turning the power connector or battery. If not, try reinstalling the power adapter or battery. Possible problem conditions are deformation of the power connector or a decrease in the elasticity of the battery contacts.2. If the power supply or battery connector is good, use a multimeter to measure the output voltage of the power adapter or battery. Mainly check whether the output voltage is stable and whether the actual output voltage value matches the nominal voltage of the power supply. If the output is unstable or the actual output voltage is very different from the product specification, replace the damaged power adapter or battery.
3. If the above detection steps are normal, you can infer that the problem is on the notebook power board or motherboard. Open the notebook case and check that the power board is in good contact with the motherboard.
4. If the power board and battery are in good contact. Then use the replacement method commonly used by DIY to check whether the power board is normal. If it is not normal, replace it.
5. If the above method is used, confirm that the power supply board and battery are normal. It can be inferred that the notebook motherboard or other main components are damaged (such as a boot circuit problem), and the motherboard can be repaired or replaced at this time.
Second, get the problem:
1. Check the power adapter indicator light. If the indicator light is on, it is generally considered that there is no problem between the power supply and the adapter. It must be ensured that the indicator light itself is not broken.2. Check if there is any power between the power adapter and the computer. This can be indicated by the indicator light of the notebook. When the power is charged to the notebook, the charging indicator will light up. Otherwise, it will not light up. Or try to find a power adapter exchange of the same brand. Use your power adapter to hold the other party's notebook. If the other computer is working properly, your power adapter is fine. Otherwise, there may be a problem with your power adapter. If your computer's power adapter is plugged into your computer and your computer is working properly and your own power adapter is not working properly, then your power adapter has a problem.
3. Observe the change of the indicator light of the computer. If you plug in the power adapter, you can see that the charging indicator lights up and off, there is no time to go, then there is a problem with the power adapter interface in the notebook, generally the inside of the cable is broken, the board is aging, welding Drop and other reasons. This is called a virtual soldering phenomenon. This situation can only be repaired by professionals.
Laptop power adapter FAQ:
1, are the same nominal voltage of the power supply, the output current is not the same, can not be used on the same notebook?
The power supply voltage is the same, the output current is different, and it can be used on the same notebook. The basic principle is that a large nominal current source can replace a small nominal current source. In fact, the current is large depending on the load in the case of the same voltage. When the notebook is running at high load, the current is larger. When the notebook enters standby mode, the current is smaller, and the power source with large nominal current has sufficient current margin.2, the same machine, other people's power supply temperature, my always hot, why?
Don't doubt that your power supply has a problem, is it like the two USB hard drives mentioned above. The processor runs at full speed, the hard disk is madly read and written, and the optical drive reads the disk at full speed. At the same time, the battery is charged, the music is loudly loud, the screen brightness is the largest, the wireless network card is always detecting signals and so on. It is very important to make good use of power management and adjust the working status of the books according to the tasks.3, the power supply nominal voltage is much higher than the voltage of my notebook battery, will not go wrong?
First of all, it is important to know that the power supply to the notebook is not the same as the power supply to the battery. Battery powered, the output of the battery is pure DC. The voltage of the battery is neither possible nor well planned. The chemical characteristics of a lithium battery determine that the output voltage of a cell can only be around 3.6V, so many batteries use a three-stage series, and 10.8V has become a very popular battery voltage. Some batteries have a nominal value slightly larger than an integer multiple of 3.6V, such as 3.7V or 11.2V, etc., in order to protect the battery.The above is the cause of the laptop power adapter problem and how to get it. If the problem is serious, you can try to change the power adapter. You can browse our user-friendly online store oriccabattery.co.uk.
