# **DISCLAIMER**: Use the script at your own risk. I've been running it successfully for several days now
# but I can't say that this is a safe practise and **I cannot guarantee that it won't damage your laptop**.
# Use it only if you understand what the script does, if you understand the risks involved,
# if you understand what those settings are and, finally, if you feel comfortable with tinkering those values.
# In any case, I won't be held responsible if any damage happens to your laptop.
