I tried installing Windows 7 Ultimate SP 1, 64-bit on a netbook (Lenovo IdeaPad S110), which has the Intel Atom N2800 (1.86 GHz) as its processor, but I get the following error message when the Windows 7 installation DVD is loading:

Screenshot says "Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode".

It says "Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode".

The Intel Atom N2800 is a 64-bit CPU according to its webpage.

I am wondering why the Windows 7 installer shows this error message, despite this. Is there something I must configure first before installing Windows 7, 64-bit? Or is the netbook not compatible with a 64-bit OS?

I am trying to format the netbook and install Windows 7 Ultimate 64-bit, instead.

Other details:

The netbook has 2 GB RAM.
The netbook initially had Windows 7 Starter (32-bit) installed.

Why does my laptop resume immediately after suspend?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More

I hope this question doesn't get closed at once :) I have an old laptop, a Compaq NC4200, which is going its final laps around the track these days. Battery is dead, and everything kinda runs slow. It also has only 1GB of memory, and even though I don't know if it can take more, I probably wouldn't… >>> More
