In this article you will learn how to fix laptop or notebook battery charging problems. Below are a lists on the most common laptop battery failures together with it’s possible causes and solutions.
* Trouble: The laptop battery can sometimes receive charges only when the power plug is wiggled
Possible Causes and Solutions:
The battery charging failure above indicates that either the AC adapter or the laptop itself has a problem. In order to isolate the faulty one, first you need to test the AC adapter with a voltmeter. If the AC adapter has a normal output voltage, then probably the power jack of the motherboard is defective. In this case, you need to replace or just resolder the power jack of the laptop motherboard.
* Trouble: After the laptop battery arrives at vital period, it discharges very quickly
Possible Causes and Solutions:
The battery charging failure above indicates bad battery. Due to old age, laptop battery sometimes act abnormally, like for example, the symptoms above. Laptop battery manufacturers believe that a typical life span should be somewhere between 2 to 3 years. If your battery already reaches this stage, the only solution is to replaced that battery.
* Trouble: The laptop cannot detect the battery anymore!
Possible Causes and Solutions:
If you are 100 percent sure that you properly installed and positioned your laptop battery into the battery compartment of the laptop but the laptop still cannot detect your battery when you log in to Windows, the problem lies only on the two components. There are two main factor for this trouble, either the battery itself or the mainboard of the laptop is defective. To solve this, first you need to replace the battery with a working or a new one. If the error persist after you replace the old battery, then you probably have a bad motherboard. Either the battery terminal which connects the battery and mainboard is defective or the circuit driver of the laptop motherboard which controls the battery operation of the laptop. The solution is to replace the motherboard or do a component level repair on the laptop motherboard.
* Trouble: Laptop detects the battery but turns off when the power AC adapter is removed from the laptop or unplugged from the main power source.
Possible Causes and Solutions:
When you log in to Windows, you can see that your battery is detected by your laptop because it shows in the battery icon located in the system tray the remaining battery charge and the computer shows that it is charging. But when you unplug the AC adapter, the laptop turns off. The probable causes for these trouble are maybe the battery is not seated properly or the battery contacts got dirty because of some of dirt or something. If these might be the fault, try to use a toothbrush and scrub the battery terminal that connects the battery to the mainboard of the laptop and reconnect the battery and make sure that it is properly seated. If these methods doesn’t help, most likely the battery is already busted due to old age, try to replace the battery with a working or new one. If replacing the battery still doesn’t solve the issue, obviously the trouble has to do with the motherboard. Perhaps the battery charging circuit of the motherboard is damaged or not working. In this case, you’ll have to do a component level repair on the motherboard or replace the whole motherboard.
