My laptop fell down while charging And seems that something broken is stuck under the power button, but it is still charging, I went to a shop which some how managed to turned on without pressing the power button but using the keyboard. I forgot to ask him what button to press to switch on the laptop. My laptop is still working 100%, could please anyone of you help me switch on my laptop? I am a student and I need it for my work. Thanks in advance

Their are a couple of different ways you can jump start your laptop. What it sounds like, the repair shop had changed the BIOS settings to power on with a different button. Their is more information here. However, their is a way you can actually replace the power button and HP has an official repair guide that you can find here.
