the quiet mode for the HDD allows for it to actually slow down the read and write times, so that read/write head is actually moving slower, resulting in less noise from it.

 

great, but interesting find.  :smileyhappy:

I have a Inspiron E1505 and I experienced a random high CPU usage check here

This has happened just two days, the first day happened like three times in like 5 hours window, like two days after the same problem happened, but onli once

 

This was last week since then, the computer has been working fine...

I'll check that option and see how it is, and I may test it..

yes, switching wireless on/off was a trick that worked too on the Latitude D620, but in my case it didnt fix the problem permanently... it required resetting the wifi connection like 2 times an hour..
