I've a Dell Inspiron N5110 laptop with the following specs:
- i5 processor
- 4 GB RAM
- NVIDIA GeForce GT540M
- Ubuntu 12.04LTS
My laptop is overheating and the battery is lasting for only about 1.5 hours. I had checked if the battery indicator was problematic but it turned out it wasn't. I drained the battery to it's least possible value and that came to around 1 hr 40 minutes. In fact, I've the same problem with Debian and Xubuntu as well. I would like to get some proper solution for this.
FYI: I've been having this problem since Ubuntu 11.04 but I'm not able to solve this in spite of trying various fixes like reducing brightness, Removing startup apps, Updating kernel and what not?. I'm a big fan of Ubuntu but this problem is stopping me from using Ubuntu and I'm using Win7 for 90% of the time.
