Hi All, I have had many problems with this laptop. High pitched key noise on some keys, rattling noise from the screen... etc. However, the most annoying one is a loud click noise coming form the hinge I believe when I open the laptop after it has been closed for a while, it is really loud and clear and happens every time. I'm pretty sure it was not like this during the first month. once the click happens, it can't be reproduced directly. the laptop has to be left closed for about an 2 hours. and after that, the noise returns when opening the lid. any suggestion? any one of you is experiencing the same? Thanks.
