what i have to do??

Answer 1

1. Install tlp (with commandsudo apt-get install tlp), then under Tunables tab at powertop most parameters should switch to "Good" once the laptop is unplugged (use r to refresh powertop).
2. Open Software & Updates and at the Additional Drivers tab select the proprietary gpu driver if it is available. Also intel-microcode may be a good option if it is also available.
