Try this
1. Remove the battery and charger
2. Hold down the power button for approx 30 seconds( this releases static electric in the capacitors)
3. Plug charger and battery back in and see if it worked

After what Whitey said, removing battery,charger, and holding power button for 30 seconds, try holding windows key +b then press the power button, and continue holding windows key +b (some laptops are win key +v) this will try to restore the last known good bios.
