Alright, A1151 is a Mid 2006 MacBook Pro. If you want to keep running Mac OS X Leopard 10.5, simply follow these steps (THIS METHOD WILL WIPE YOUR INSTALLED HARD DRIVE!!!): 1) Insert the original DVD into the tray and turn on your mac while holding the "C" button down. You will actually feel the disk spinning up. Just to be sure, keep holding the "C" button until the Apple logo will appear on the screen. 2) When the installer boots up, you will see a language selection menu. Select the one you need. 3) On the "Welcome" screen click "Continue" 4) On the license ageement screen click "Agree" 5) Next is the "Destination" screen. You might have to wait a few seconds before your hard drive will be detected, then click on the image of your hard drive - a green arrow will appear on it 6) If no compatible partitions are detected you'll need to repartition your HDD. To do that, use Disk Utility (choose Disk Utility from the Utilities menu). In Disk Utility, click Partition. If you partition the disk, you can select a ...

Hi Robin! I will assume that you have a wireless router that gives out IPs automatically when connecting to your network and it's protected by a password. If that's the case, we should consider the following options: Reset iPod's wifi settings: 1) On your iPod, go to Settings -> Wi-Fi 2) Make sure Wi-Fi switch is set to "ON" 3) In the list of wireless networks under the "Choose a Network" label, find your wifi 4) If there is NO check mark on it, tap on it and enter your wifi password; if there IS a check mark tap on the arrow that's on the right side (white arrow in a blue circle), then select "Forget this Network". A confirmation popup will appear - tap on the red "Forget" button. 5) All the fields like IP, Mask, etc. should now be blank; tap on the "Wi-Fi Networks" arrow that's in the top left corner of the screen 6) There shouldn't be a check mark next to your wifi name anymore; tap on your wifi and enter the password; tap the Join button and in a moment you should be reconnected to your router. If all wen...

Hi Mammakim4him! You haven't mentioned the exact model of your MacBook. I have ran into some issues on particular 17" MBPs installing older systems. My choice would be installing Mac OS X Lion 10.7. Expensive ($70) and fast way: The fastest way to do so is to buy a thumb drive from local Apple Store: http://store.apple.com/us/product/MD256Z... They are always in stock, however paying $70 might not be the best choice since Apple is about to release 10.8 Mountain Lion in a while. Less expensive ($30) and slow way: An other option would be to download a copy from Mac App Store. http://itunes.apple.com/us/app/os-x-lion/id444303913?mt=12 In this case you'll have to: 1. Have a Mac with at least Snow Leopard (with App Store) 2. Wait until almost 4Gb download 3. Extract a bootable DMG image from the downloaded software 4. Burn it on a DVD Free: Borrow a copy from someone. Or find a way to download a file called "InstallESD.dmg" - the bootable image of Lion installation :) Either way is fairly simple to install and I'...

One of my macs has the same issue. It's a Macbook Pro 15" Late 2006 MA610LL A1211 It's whether the screen cable's connector or the port on the logic board. Whenever the black goes red I press down the keyboard, over the following buttons: [;'p I don't feel like taking this laptop apart right now, but if the "pressure" workaround will keep working, I'll just open it up and apply couple of layers of electric black tape over the flex cable connection.
