    First do a long press of the power key to force a full power off. That gets you out of any weird sleep mode it might be in. Wait for a bit after the shut down and try turning it on normally. If that doesn't work the next step is a battery reset. Some models do a battery reset with the long press on the power button, some have a battery reset pin hole, usually under the laptop. If you have the pin hole disconnect power and use a bent paper clip to press and hold the reset for 15-30 seconds. Release the reset and wait 15-30 minutes to make sure everything has bled away. Plug power back in but wait for it to show the battery is full before turning it back on. Report back with your results.

    My laptop doesn't have a battery reset hole.I have tried pressing the power button for like 2 minutes long.When I keep pressing the START or some other button the Laptop turns on & work normally but after releasing the same button I used to turn it on, within 2-3 seconds it turns off.
    Even I started the laptop in the way I described & shut it down from Start menu Power option.
    I tried removing the AC adapter then the battery,Keyboard ribbon,HDD,SSD,RAM and pressed the power key for 45 seconds for any unneccessary static to go away,then placed everything back correctly only to achive nothing.Please help !!!!!
    Also when the laptop is switched off If I plug in the charger,the amber light keeps blinking at a interval but when the laptop is on then the same light stops blinking completely & becomes steady and then the laptop charges smoothly.

    The battery reset process on machines that use the power button requires you to have power disconnected. Unplug, press and hold the power button for 15 seconds or so, wait a few minutes and plug power back in. Wait for the full charge indication and then turn it back on. Let us know if that makes a change.

    @billsey I tried it..But when I connect the charger after doing what you said,the charging indicator(Amber light) becomes steady for a few seconds then blinks 2-3 times & turns off, after 1-2 seconds it turns on again & repeats the same over & over again.
    Also by unplug I hope you are referring unplugging the AC adapter not the built-in battery.
    Anyways I will try it again exactly as you said when I reach home & will let you know the result.
  • He is referring to this procedure:

    It is necessary to disconnect the power adapter.

    @egydiocoelho I have checed the keyboard ribbon cable..It is well connected..But on the adapter where the power connector points are the ribbon looks like it has come out a bit, I tried to press it a little but it's not going inside more than that.
  • OK! Now, what happens when you disconnect and reconnect the keyboard?

  • When you disconnect the lithium battery, does the laptop turn on by connecting only the power adapter?

    @egydiocoelho Nope..If I disconnect the Internal battery & connect the power adapter even then same problem persists (Laptop is turning on by any other switch except the POWER key.)
    And by the way my laptop's exact model no is AN715-51-75WR..
  • is your laptop still under warranty?
