Posting for a buddy of mine.
He recently purchased a g73JH-1A. Thing ran great for a couple of days. He was getting the static issue with the sub, which was reported to be fixed using bios update 213.
He placed the update on a memory key, went into the bios via F2, and applied using EZflash. It flashed correctly, reported it was shutting down in 2 seconds.
So far so good.
Pressing the power button on the laptop now produces NOTHING - no power, no fans, no response. It just clicks.
Adapter is giving correct voltages.
Harddrives have been removed.
Reset hole has been pressed
Laptop has been "power drained" by holding the power button for 60+ seconds with the battery and the adapter unplugged.
Any known of common fixes for this?
