Question about Apple Computers & Internet
When I hit the power button nothing happens at all. I've tried the SMC reset via removing the battery and holding the power button, AND hitting the keys (Option+Control+Left Shift+power button). I've reseated the RAM and tested one stick at a time. Help!

When my Mac decided to no work when power button was hit, only two options came to mind, Power Button or Motherboard.
Turns out, power button is connected to keyboard which was the problem. The fix was easy, new keyboard.
Hope this helps.

SOURCE: MacBook Pro 15'' RAM Problems
The earliest MacBook (Pro) models have a limit of 2 GB. To check the specific model, in the Apple menu select about this Mac. Then press more info... . Look at the line like "Model Identifier: MacBook5,2" for my white early 2009 MacBook. If the numbers are 1,1 then for sure you have the oldest model and are memory limited to 2 GB, as the sum of both cards.
That's just like my wife's, it was a Core Duo and not the current Core 2 Duo. Works fine. I was ready to up its memory but read about this in the Apple Support Forum. It came originally with 1 stick of 512 MB, IIRC. I upgraded it to 2x1 GB for a lot more than the 2x2 GB in the newer. BTW some of the Macs between these only take 3 GB but will work with 2x2 GB just throwing 1 GB away. -Ken

SOURCE: MacBook won't start up.
If you have your Mac OS X Install disc, insert it into the drive.
Restart the computer and hold down "C" while booting.
Choose your language.
Select "Disk Utility" from the "Utilities" in the menu bar.
Select your Macbook's hard drive in the left sidebar.
Click the "First Aid" tab thats along the top of the viewer window.
Click "Verify Disk" (not verify disk permissions)
If this shows errors click "Repair Disk"
Once completed close the Disk Utility window.
Restart the computer.
If this fails to fix it as well then your next option would most likely be recovering your files from the macbook either by booting into target disk mode (hold down T at startup) and transferring them via a firewire cable, or removing the hard drive and hooking it up to another Mac to get the files. Then do a clean install of Mac OS X using your installation discs.

You may need a certain connection (MiniDisplay Port to DVI, or MiniDisplay Port to VGA). If you're connecting to an HDMI-compatible projector, you'll need an adapter. You'll also need an adapter if connecting your MDP (MiniDisplay Port) to a DVI or VGA port. Here are some helpful links:

#2 MDP to HDMI Adapter (RadioShack)
#3 MDP to VGA Adapter (Apple Store)
#4 MDP to DVI Adapter (Apple Store)

You may need to reset the PRAM.
Start your computer and hold down the option, command (apple), P and R keys simultaneously until you hear the second chime. Then release.
This will reset the perimeter RAM (PRAM) and may allow your system to start, which it will do immediately if it capable.
If this is not the case and you have already tried removing the RAM and the HD, you may need to have the motherboard tested.
