Hi everybody I have just a question.
I heard the laptop_mode can ruin the HD..
If I enable it by doing

Code:

# echo 1 > /proc/sys/vm/laptop_mode

how much it could be dangerous for my HD?
Also I never use battery, so, how does it can be usefull? Laptop mode affects also the fan?

Code:

~$ sudo smartctl -a /dev/sda | egrep '(Load_Cycle_Count|Temperature)'
193 Load_Cycle_Count        0x0012   098   098   000    Old_age   Always       -       20910
194 Temperature_Celsius     0x0002   134   134   000    Old_age   Always       -       41 (Lifetime Min/Max 12/54)
