>> The left hinge on my tibook has stared to sound very dry and is >> beginning to squeak. As this was replaced (under Applecare) about >> 1yr ago after freezing up and snapping, I am wondering if there is >> a lubricant (WD40?) that should be applied. There is a tool set that comes with lubricant that is available from RadTech. If you are interested, I have one for sale that I used. Comes with tools including a TiBook Hinge Wrench and Lubricant and instructions. Contact me off list if interested. Thanks, and so long for now, TOM
