The primary reason behind it remains unconfirmed. The issue could stem from a faulty battery, a defective motherboard, or a potential manufacturing fault within the device. Most of the time, if your device is still within the warranty period, it will be replaced with a new one. Otherwise, you may need to take it to a repair shop.
But there are a few tricks that will save you a lot of time and money. You should try method 1 first. If that fails, then try method 2 to troubleshoot the problem and hopefully you will find where the problem is. Before trying these methods, make sure you have checked these things.
Things to check before trying Method 1 and 2
Method 1: Unplug battery and AC adapter
Note: The steps of removing and inserting the battery might differ a little bit depending on your specific model. If you are not sure then follow the steps mentioned in the user manual (that comes with the device and is available online) of your Sony Vaio.
Method 2: Unplug everything and direct AC method
Should you have recently installed new RAM in your device, remove it by following the user manual that came with your Sony Vaio, or by visiting a repair shop. Then, proceed with method 2. If your laptop functions properly afterward, this indicates that the installed RAM was faulty. If none of the methods mentioned here work, then contact customer support or go to a repair shop near your home.
