I need urgent help... So a few months ago, i had the same exact issue, where my gl553vd suddenly turns off completely (no "shutting down computer" sign, no "low battery" sign, no nothing) except for a subtle click, similar to the one you hear whenever you are plugging earphones... I had someone fix it for me, told me it was the motherboard so they replaced it but now, the same thing happened. And i hear subtle continuos clicks inside my laptop and just wont turn on... pleaaase help!!!
