Why laptop is not getting on?

Let's start with the basics. First, check your charger is firmly connected at both ends. Try a different mains socket to be certain. If there's still no life, try a power drain. Disconnect it from the mains. If the battery is removable, take it out. Then, hold down the power button for 30 seconds. This often clears any residual charge. It’s a simple trick that frequently sorts the issue before you need to worry about hardware failure.
