Computer: Lenovo Laptop: Wouldn't start, power light glows and turns off automatically?

It was working fine two days back, no OS issue. Now its not turning ON.
1) NO fan noise or HDD noise could be heard,
2)screen is blank
3)Tried hard reset of power- removed battery, tabbed power button for number of times without power supply for +30 SEC each, then plugged in, inserted battery and pressed power button. Just "power ON light" lights up and automatically turns OFF.

Sounds like a capacitor on the motherboard might have went bad on you. You can get that verified by a repair shop.

Or? Could your charger be bad?
