N5110 not starting up, is this a motherboard issue?

Question

Hi, my N5110 was dropped earlier, and it won't turn on now. There are no beeps, and neither is the fan turning when i press the power button. When the power cable is connected, the power button and two of the LEDs on the board (FPLED1 and the HDLED) blink every 5 seconds. The charging LED (CHLED) does remain constantly turned ON.  When only on battery, the LEDs blink every 3 seconds, and this time, the CHLED blinks an amber light instead of white. In both cases, pressing the power button does not make a difference as such, but if I time the press to happen at the same time when the blink happens, then the LEDs turn ON at the same time. I also removed the power button connection, and the two LEDs were still blinking. I have checked the hardware and there is no visible damage/burning marks anywhere. I also checked the connectors/cables and found no problem. My fear is that either the motherboard or the processor might have gone dead. Please help me on finding out the actual issue.

Hi,

Try to remove Ram and battery first, and then turn on with direct power supply.
disconnect the AC adapter,remove the battery,press and hold down power button for 30 seconds.Reconnect the battery and AC adapter,try to turn on system.If it doesn't work the first time you try,try it couple of more times and see if it helps.
Try to use different power adapter.

1. Tried, but still the same result. 2 LEDs blink every 5 seconds.

2. Tried, no success :(

3. Will try, but a bit skeptical as i think the damage occurred to the laptop and not to the adapter. Also, note that trying to power the system only on battery produced the same blinking.
