Hi,

I am a new member of this forum. I used my Macbook 7.1 with Snow Leopard and Windows 7 64 bits and Linux - Ubuntu 11 installed in the same machine. I discovered one major issue [a bit annoying to me personally] that the when I plugged in Macbook 7.1 the mini-display port to connect the external VGA display using Apple genuie mini-display port to VGA adaptor to Samsung external 27" monitor, the Power Save [screen off, auto sleep, and screen saver mode auto-on after certain pre-set time] does not work and activate with the mini display port plug in. But when I just use the Macbook 13 inches screen, in Win 7, the power save mode works normally. I google searched a lot but there is no solutions for this. Does any one experience the same issue under Windows 7 64 bits.? Thanks.

First, for best results you should be using the digital output from your MB not analog. Mini Display Port to DVI to the Samsung not VGA.

As for the power saver problem, the only thing I can suggest is to try to update your video drivers for Windows 7 x 64 bit. Go to the nVidia site and see if they have updated drivers for the 320M. Also make sure you have the latest version of Boot Camp installed. Use the Apple software update from within Windows 7.
