Sometimes when it spins fast enough or slow enough the rattling is gone and all that is left is the normal whirling. It is really irritating that it randomly goes into the RPM range for rattling and throws my concentration off and gathers people's attention in a library.

Not only is the clickpad still a hit and miss, I now have fan noises to worry about which I can't get used to unlike the clickpad. It is my priority to fix the fan noise now. What should I do? Is it possible to backdate the BIOS? Will that be recommended? Will it solve the fan problem?
