Hello Perry, It is very strange that you are receiving the 3 diagnostic lights but no activity from anything, are you certain the Hard Drive does not attempt to spin?

We can also try trashing the Airport plist, this can be found in the following directory; /Library/Preferences/System Configuration/ Delete com.apple.network.plist and com.apple.airport.preferences.plist You may need to enable the Library since you are using OSX Lion, this can be done by typing the following command into the Terminal, found in the Utilities section, chflags nohidden ~/Library/ Send this file to Desktop to keep it safe for now and then restart the Macbook. Now try to find your network. Hope this helps,

You can heat up the glue that holds the trackpad together and then remove the glass form the sensor. you would then need to 'scrape' away the silver colouring that is painted onto the underside of the glass. I am not sure how you would then go about colouring the glass before re-seating the sensor back against the glass. Also I do not know how sensitive this would then be after this process. You need to be very carefull doing this as the glass shatters into very very fine splinters if bent too much. Hope this helps, Wes

This usually means the the computer is unable to find bootable media. If you hold down the Option key (Alt Key) when switching on the Mac do you see any drives appear? We can verify whether the drive is functioning correctly by following the steps below; Start your Mac. Put your OS X install disk in the optical drive. Restart the computer, then hold the C key during startup. From the Utilities menu, choose Disk Utility. Don't click Continue. Select your Mac OS X disk (named "Macintosh HD" by default) in the left side of the Disk Utility window. Click the First Aid tab. Click Repair Disk to verify and repair any issues with your Mac OS X startup disk. After repairing the disk, try to start up normally. If the repair fails then you will need to replace the drive. If this passes you will need to re-install your OSX from your provided installation disc. Hope this helps, Wes

You can purchase extra strong double sided sticky tape to hold the glass in place.

Before attempting a self repair on this I would personally take this to Apple under your 1 year Manufacturers warranty. If you would prefer to take a look at the issue yourself then you would need a T6 Torx screwdriver to remove the screws from the fan. Hope this helps, Wes
