every time you post its something different :/ first it was whole thing dead, now you say leds work ?
>When power button pressed in power switch board 3 LED'S are lights on only 5 secs. after that Led Lights off. can't stay..
THIS is one of GPU failure modes, bios cant initialize gpu and turns computer off. GPU bad, need replacement, ~>$100 + labour, after that someone would probably need to replace keyboard or keyboard controller. all in all more than whole laptop is worth.
Yes. This Problem is i Observed. when put load in to Mother board (CPU, RAM, HARD DISK, DVD WRITER, KEYBOARD..etc.,). Voltages Drop Down. Once Turn On with Load stuck at booting only 10 to 15 secs . after that automatically turned off. can't turn on again. I Remove all Components from Motherboard. and check voltages in LdO3 ...2.22v and LDO5 3.20 Volts. so Voltage Drops in to MAX8734 With Load.
