Hello,
can you check if your laptop has entered the suspend mode successfully when the lid was closed?
you can check the power LED to see if it blinks, or check the fan to see if it's still running.
Thanks

Hello,
Yes, Laptop is going in suspend mode after lid is closed and also Power LED blinking and fan is running. But whenever i open lid and try to press any key and power button, laptop is not getting open. So i need to hard reboot.

OK this sounds like the unable to wake from suspend is the major issue here.
Please try to update your system and install the graphic driver (if available) to see if it helps.

If it's still not working, try a newer version of Ubuntu, or open a bug report with "ubuntu-bug linux" from a terminal.
