I don't think the switch being broke off is related to "laptop is just not booting up properly, laptop shows power light for 1-1.5 second & then everything goes silent. "
It's a tact switch. Is there a missing button on your laptop? Or a button that doesn't work anymore? That's the switch that would be behind a button or membrane.
@jay32267 power button is working fine, laptop is just not booting up properly, laptop shows power light for 1-1.5 second & then everything goes silent.
If the problem is being caused by that falling off....it can only be one of two things.....either those two terminals on the PC need to be shorted or open.
