As per the title, I have 14z running Windows 8 originally (upgraded to 8.1 now to see if that fixed the issue).
It was working fine, but for the past month or so it will not shutdown or suspend. Upon trying to do either it goes through the shutdown process as normal, the screen goes blank, but the power switch stays lit, as does the little power LED on the front edge. Pressing the power button or any other key yields now response. The only way to recover the machine is to hold down the power button and force it to shutdown. After this it boots as normal. I Have tried the following:
1) Turned off Hybrid sleep under all power profiles.
2) Turned off WOL on all adapters, although after every reboot the N2230 wirelss card keeps turning the option back on.
3) Disabled the Microsoft Kernel Debug Network Adapter
4) Uninstalled the display driver, but it picks the same one back up after a reboot.
5) Boot the machine safe boot mode, but the issue still persists.
6) Tried to do a refresh, but it asks for the Windows DVD which wasn't supplied with the machine.
7) Run SFC scan and checked the CBS log and other event logs, but cant see anything relevant to this problem.
8) Run troubleshooter, nothing found.
9) Finally in frustration upgraded to 8.1, which didn't resolve the issue either.
All updates have been applied and I've read through the dozens of other posts about this issue (here, MS forum and other forums) and tried the various suggestions, but nothing has worked.
The machine has automatic updates setup, so I can only imagine one of those has caused the issue. Its my dads machine, so has very basic use, with very few third party Apps ever installed.
Any help or advice would be greatly appreciated, as I'm thoroughly fed up of this machine and Windows 8 at this point. The OS really seems like a hodge podge put together with the efforts of a million disperate coders working in isolation from one another. And I really don't understand what Dell expects us to do without an OS CD or ability to burn one for critical recovery of existing installs.
