Downgrading Asus S56CA-BH51-CB ultra notebook from Windows 8 to Windows 7 Pro 64 bit

Hi All,

I purchased an Asus S56CA-BH51-CB ultra notebook and I downgraded the OS from Windows 8 to Windows 7 64 bit.

I went to the Asus website and downloaded all the drivers for the Windows 7 installation (since the notebook at one time
came with Windows 7 installed) and proceeded to install Windows 7 Pro 64 bit.

Things I did ==>

I adjusted the UEFI bios by ==>
a) enabling CSM
b) disabling secure boot

I then booted to a USB drive and installed
Win 7 from it.

Anyhow, as soon as the OS installation was done
-----> even before I had installed any hardware drivers <-------
I tested the system to see if it would fully turn off or
go into sleep mode. (it would do neither!)

a) When given the shut down command the unit
turns off except the light on the power button stays
lit.

b) When given the sleep command it does the same
thing as above and it won't go into sleep mode. On reboot
the computer will offer to re-start on safe mode.

In either case the only way I can re-start the computer
is to hold the power button down for about 8 seconds -
'till the light goes out - and then I can re-start.

Mind you, this is brand new computer, There are no problem
driver installations in Device Manager.

On a lark I also downgraded the BIOS from v208 to v206 to see
if that would do the trick...but it didn't.

Does anybody know what is causing this and how to fix it?

I thank you for your help.

where'd you get your W7 ISO? is it recovery media or a did you do a clean install?

 

Hi,

It was a clean install from a downloaded ISO through digital river, a MS reseller.

Did you install your chipset drivers? Why don't you install the drivers for your laptop and test again.

 

Add a graphics driver for good measure, many a times an improper - or lacking altogether - graphics driver will adversely affect the sleep function.

Good luck.

 

Hi Pirx and ajkula66, thank you for your input.

To recap ==>

I installed chipset driver (no change, problem persists)
Installed the video driver (also no change, problem persists)

One of the things I haven't tried is removing the BIOS battery,
Do you know it's location on the S56CA?

I thank you for your help and look forward to your reply.
