Hi. As I have gotten older I now work on the premise if it ain't broke don't fix it. But it may be broke and there may be a fix. But is there a catch?

I have a Haswell Laptop will intel 4600 GPU - Dell drivers, installing Intel's drivers is not possible as it says Dell does not allow it.
It also has an Nvidia 750M whcih i have updated the drivers.

Problem is when i wake up from sleep the screen remains black. The fix is easy, just put it back to sleep and wake it again.

The question is:
1) Is Dell locking out the Intel Driver because it has a special code to save power (eg forcing Laptop to use Intel while not doing GPU intensive tasks? - or is this technically impossible for those who knows windows 8 power management?)

2) Will uninstalling the Intel drivers and reinstalling work? or cause some weird problems? I read somewhere that some people who cannot install intel drivers for a different reason need to uninstall Nvidia before installing intel (but i suspect mine is a different issue).

Oh the joys of technology
