Hi Sir, i own this laptop , my laptop got hung today and shut down and now it is not starting at all. I did hard reset by pressing the reset button at back of laptop , i changed the 8GB RAM to another slot and also removed the internal battery and plugged in the battery again but laptop is not turning on, when i plug in the laptop power charger cord it shows orange light and light under the keyboard flickers if i press power button, any suggestion are really helpful to fix the issue ?
