My Hardware
Macbook Air Early 2008 (MacbookAir1,1)
OS X Lion 10.7.5
Problems
1) Display backlight is off for minutes after waking.
When I wake up my MBA from a longer sleep or after being off for more than say around 15 minutes, I'll have to wait sometimes up to 5 minutes to use it, if I shine my flashlight through the logo on the back, or onto the screen, I can see that everything is still working perfectly, it's as if I had turned the brightness down to last setting, turning the brightness up with the F2 brightness hotkey doesn't make a difference, although the brightness bar in the little applet goes up. Also I seem to notice a direct dependency in time turned off to the amount of time it takes to come back on. I also know that it isn't still asleep, because, the 'breathing' light at the front goes out.
2) No Sound from Built-In Speakers
This one is perhaps even more of an inconvenience, I don't see any sign of them in SysPrefs Sound Settings, or Audio MIDI Setup, however, I do hear the startup chime, so I knew they were okay. But once I boot into OS X, nothing. Only headphones show in Output Devices, even when said headphone jack is physically removed from the computer. I do however get sound through earphones. And even when they are plugged out, I have no restrictions in volume changing as I have seen with other people on the internet, also this laptop is not capable of digital audio out, so there will be no red light.
When I boot into a Ubuntu Live USB however, everything changes
Everything works like a charm, I can close my clamshell for as long as I want and it the screen pops up as soon as I open it, Speakers work wonderfully and so on.

Ubuntu live USB, is the only thing I've tried that yielded any results, and I really don't want to resort to using it as my primary OS :(
EDIT: Internal Speakers actually show up in System Information..forgot to put that
