[ltp] Thinkpad high pitched noise

[chris]

Hi list:

I think this issue has been discussed on this list before, but I can't recall 
what specifically it was about. Just recently, I am getting increasing 
annoyed at the high pitched noise that my thinkpad R50 emits while the CPU is 
working over 1Ghz, I googled around and found out it is due to 2.6 kernel 
which uses 1000Hz so makes capacitors work a lot harder? But I can't bear the 
noise any more, replacing the thinkpad it's an option nor going back to 2.4 
kernel, but changing process.c to 100hz can solve the problem according to 
some threads, does it slow down the computer or harm the laptop? any one?
