My laptop is not turning on

@adityaagra56631 you are not telling us if anything happened to the laptop or if this just happened all of a sudden.

Let's start with the basics. First you want to check your power supply. Make sure it has the proper voltages. Check to make sure that connectors are not bend etc. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. that prevents it from working. Clean it of any debris etc, use a few puffs of air to clean it out. If none of this works, get a ammeter and see if your laptop draws any amperage from the charger. After that, you need to check and see if your motherboard even gets power. For that of course, you need to open it up. Post Some good pictures of what you see. That way we can see what you see.

After that this might just turn into a board level repair. For that you have to make sure that you have the proper tools as well as good skills. It will also help if you can post some good pictures of your motherboard as well as telling us exactly what teh board is. On the Lenovo computers, the number will be on the top side (the side that faces the keyboard) You will have to remove the motherboard.
