I have been using my EEE PC 1015PN for nearly 2 years now, and I am quite satisfied with it. But after the release of Windows 8, I wanted to try it, too. So I decided to upgrade install from my Windows 7 Professional to Windows 8 Professional. Before this test, I made an Acronis Image, which turned out to be an really good idea. Installation itself needed about 1 1/2 hour, as I decided to upgrade and not start from scratch.
The first problem started to come up after going to the desktop and trying to change the brightness \ wifi connectivity by using the FN Keyboard Shortcuts: "Asus ACPI Driver missing", was the error. So I tried to reinstall the needed keyboard drivers, and Optimus Tool (1015PN uses an Intel as well as an NVIDIA Graphicscard).
After rebooting, I was able to choose the Optimus setting within the tool, and I could also change screen brightness with the FN Keyboard Shortcuts - but nothing else.
So I decided to shutdown the PC, enable WIFI in the BIOS and reboot - to check WIFI Connectivity, as well as to see the Intel Graphics active in Windows 8. So I pressed the "Save and Reboot" shortcut in the bios - and that was the last thing I saw.
After that, the EEE PC tried to boot once, and then stopped working, rebooting again - boot loop. But not after 20 seconds of boot, no, it already fried seconds after starting the boot process. Even disabling WIFI in BIOS again or pressing F8 manically - nothing could help. The system was killed.
After trying for a good amount of time, I restored the Windows 7 backup. And thats it. My first Windows 8 impression turned out to be even worse than Windows Vista. And well, that was something.
How did you get optimus working in W7? I cant get it working for the life of me.....
You need to install the drivers in correct order and the Optimus Tool, as well as Windows 7 Professionell at least. Try google, there are several tutorials to that topic :).
