High CPU usage and temps, low battery life

So I have a laptop which is Dell Inspiron n5010. Recently, my battery life got short it started to end in an hour or so. I noticed that my CPU fan is loud so I checked my temps and usage. My temps are 59 and it can jump over 60 sometimes. Here is how my task manager looks like:

Take a can of air to it

Run HiJackThis and upload the log. Run it as admin.

I would sugest using the run cmd and typing:

powercfg -energy

look at the report and see if you have excessive cycling of the processor or video. Lists the warnings and errors.
