    I am attempting to connect my MacBook (about two years old) to my television. I have connected to the mini DVi port using a mini DVi to HDMI adapter then connected the HDMI cable to the HDMI input in the television. I am now getting the screen saver showing on the television (so it seems that the connections working) but none of the screen icons or any other video functions are coming through. Any ideas? Do I need to install any additional video drivers?

    Currently, your TV extends your MacBook's monitor. You can just drag windows to the TV by dragging them out of the left or right side of the MacBook's monitor. Alternatively, you can switch to mirrored mode or TV-only mode by going to System Preferences > Displays. You can also close your MacBook, plug in the TV and then press an external keyboard or mouse.

    I would not recomend closing the lid. The hot air vents through the key board. You can risk overheating.

    That is completely false. The MacBook, MacBook Pro and MacBook Air do NOT vent through the keyboard. They all vent at the rear, near the hinge. Apple portables are designed to run in clamshell mode, with the lid closed, with no overheating or other problems.

    ...they may not "vent" but don't they draw air thru the keyboard to be exhausted out the back?

    It will take air in from wherever it can find it. It's not like the computer is hermetically sealed when the lid is down.

    Keyboard is a possibility, there's also the rest of the vent opening at the back, the Superdrive and the various port openings.

    No, both the intake and exhaust is in the rear. Under the keyboard is a solid sheet, preventing significant air flow:

    As you can see, it isn't.

    Apple would not recommend clamshell mode if an Apple notebook depended on venting through the keyboard:

    If this were the case, your keyboard would get quite hot. A little common sense and logic goes a long ways.

    Ohhh. I thought I heard differently. Feels stupid as I close the lid

    I belive I've read about the false venting through the key board. Or a problem with MacBooks overheating when the lid was closed, and the MacBook didn't go into sleep mode. Maybe it was the iMac.

    You can't close the lid on an iMac. MacBooks don't overheat because they're in clamshell mode. If they overheat, it's for other reasons.

    If you're having problems with your Mac not sleeping or staying asleep:

    Hi there, I have a similar problem with the sleep/wake thing that is perplexing me, even having read through the above link.

    I plug my 13" Aluminium unibody MacBook into my TV using a VGA computer monitor cable and the relevant adapter. I get the display on the screen and all is fine until I put my MacBook into clamshell mode and wake it up using my wireless mouse or keyboard. It works for a few seconds then goes back to sleep. I wake it up again and it goes back to sleep. I have tinkered with settings to try and get it to stay awake but have no idea what to do!

    Any help?

    Thanks.

    Mark
