overheating of GPU(Nvidia gefore 920m) and degraded battery life

i have dell inspiron-5558(i5-5200;8GB DRR3 RAM;4GB Nvidia-Geforce 920M as well intel HD graphics) and i am using Ubuntu 16.04LT



in my windows i had a battery life of around 4-5 hours reading pdf but now my battery after being fully charged works for about 100minutes. even my Laptop is heating a lot i think it is because of GPU.




i have researched alot installed latest nvidia drivers. installed bumblebee and power management tools but still it is consuming alot of battery on standby



versions of nvidia drivers (i have tried all of them)



even the command optirun is not working
error in running optirun



i am not even sure nvidia is working or not or if its constantly on.
regarding temperature i dont think any ScreenShot will work but it is pretty hot.




i am not very good with linux. so please tell the commands along with the content of answers. Thank you
