I installed the PowerTop application in Ubuntu 11.04 and according to it, npviewer.bin is consuming more power than other processes.

What is npviewer.bin? Why does it take most of the computer's power?

  • What if I do sudo pkill npviewer.bin ?

This could be myriad of things. npview.bin is essentially, flash. What version of flash are you running? What version of ubunutu are you running? 64bit? Did you get flash 64bit. What web browser are you running? – Raystafarian Mar 5 '12 at 19:18

It's part of nspluginwrapper. It's probably being used to play Flash, which can be a large power drain.
