recently i was working on ky helios 300, i put everything back togrther correctly, and it just doesnt boot, keyboard backlight on but nothing else, fans spin and then stop, no blinking leds no sounds,
only sound is when i unplug it, it beeps, i chipped some sillicone looking thing off around the cpu before, i dont know if it was important or not,
please just tell me anything good, or bad, ive tried battery reset and that didnt work either
