If you have a Sony Vaio, it's very likely that you have the problem of not turning it on. Many Sony Vaio users face this problem when their laptop suddenly stops working. Each time you press the button, the green light comes on for a few seconds and then turns off. You can press the power button as many times as you want, but the green light will only come on for few seconds and you will be in front of your laptop black screen. This is quite annoying, since it can happen at any time without prior notice, even if your device worked fine throughout the last use.
The main reason behind this is yet to be confirmed. You may have a bad battery, a faulty motherboard or just a device with a manufacturing fault. Most of the time, your device will be replaced with a new one if it is still in the warranty period; opposite case, 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 must first try the method 1. If that fails, try the method 2 to fix the problem and, hopefully, you will find where the problem is.
