Over the past few years, laptops have become one of the most common types of devices, except smartphones are ahead of them. But since laptops are a technologically more complex device than classic stationary computers (although they are similar in many respects), there are much more problems with them. The whimsical place of any clamshell is the battery. Very often, the device does not charge properly. In today’s article, we will analyze the causes of such a malfunction and offer you solutions to the malfunction.

1. Charger defective – The main reason your laptop might not charge. Chargers fail regularly, especially aftermarket ones. By the way, if you have a universal device (with a switch for different voltage values), check if the voltage and current strength are set correctly (if there are options). Chargers are practically not repaired, most often you have to buy new ones. The easiest way to make sure the adapter is working is to remove the battery and try turning on the laptop with the power supply. Works? So the problem is not in the block.
2. Replacement cord required – It may have mechanical damage that is not visible to the eye. If you have a multimeter, you can measure the voltage level of the charger at the ends of the connector. If this is not possible, then try connecting another charger that is suitable for the connector. When checking the cord, pay attention to the indicator on the charger adapter. If it does not light, then most likely a replacement is required. However, the indicator itself may be damaged, so this is not a 100% diagnostic method.
3. Next – inspect the battery for oxidation. If you get caught in the rain with your laptop or just accidentally poured it during breakfast, moisture can get on the contacts and they will soon oxidize.
4. Malfunction of the battery itself – Surely, many people know that the most popular type of battery is lithium devices. Their resource is not unlimited and the more you use a laptop, the faster the battery wears out. You can try to check the battery status with a special utility such as AIDA64 (it is paid, but there is a free trial period). You can try to restore the battery – we recently described how to do this.
5. Incorrect BIOS version – If you tried to update the BIOS yourself or simply made changes without understanding what you were doing, it is possible the reason lies here. The easiest way is to return everything to the factory settings. To do this, go to BIOS and select the item there like Load defaults.
   
6. The driver requires updating – Probably, for many novice users this will be a discovery, but laptop batteries have their own drivers that are installed by the manufacturer. As a rule, there are no problems with them, but it is better to exclude this option. As a result of a system error, the driver might stop functioning properly. To solve the problem, you need to go to the manufacturer’s official website and download the necessary utility. Often, the desired files can be downloaded separately.

As you can see, before taking the device to a service center, you can perform a number of simple procedures that can save the battery. And even after the repair, you have no guarantee that the battery will work for many years. Battery troubleshooting is a very time-consuming process and often small offices deceive inexperienced users by promising them a full restoration of battery performance. Not only can this be done in very rare cases, but the cost of repairs often approaches the cost of a new battery. Give the battery to a service center or buy a new one right away? Everyone decides for himself, but we would advise you to choose any of the available analogs on the market, fortunately, now there are a lot of options.
