1. check size of a current directory with sub-directories:
du –block-size=M | sort -n
2. check size of /home/user/alex directory with sub-directories:
du –block-size=M /home/user/alex | sort -n
3. check size of /home/user/alex directory with depth=2 sub-directories:

This post is about how to fix sound problem in nc8540p EliteBook laptop with Windows 7 Pro (x64) . Just recently, I’ve had a problem with my headphone jacks. When I plug in my headphones, the sound still comes out of the laptop speakers, but no sound comes out of the headphones.
Doing some search in the internet I have got a solution (in my case it works) - IDT audio driver has to be installed instead Microsoft’s one.

2. Install it and restart computer.
3. enjoy
