Driver Power State Failure

[foreright]

I get this prompt after the system closes down sometimes during operation. It appears to happen when I project my laptop screen to the TV to playback a film. It generally happens if I close the lid - although it is set to do nothing when lid is closed.
The nearest diagnosis I can Google is that maybe there is a driver issue. My NVidea driver which works well is not a dedicated manufacturers one but a Microsoft one and recently updated.
Is there anything I should worry about?

Have you tried loading the nVidia (rather than the Microsoft) driver?

No, as I was putting out feelers whether anyone has experienced this and as to how it was remedied. I shall have to try this as a last resort as I am loathe to change drivers in case they introduce other problems.
I am going to change the sequence of Starting TV on HDMI 1/ Boot Laptop / Choose Duplicate &/or Second screen only. To see if that makes a difference and if it doesn't. Change drivers to manufacturers - unless any other feedback. I have to say without the reboot issue, the TV screen PQ is fabulous.
