My laptop not showing any single of power

@sumitdevgan you are not giving us a lot to go with. If would be nice if you could tell us if anything happened to your computer and what you have checked or even tried to fix.

You want to approach this just like you would any other laptop that does not power on/up.First you want to check your power supply. Make sure it has the proper voltages. Check to make sure connectors are not bend etc. After that, check the charging port. Clean it of any debris etc, use a few puffs of air to clean it out. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. that prevents it from working. 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 Ajout d'images à une question existante
