Did the issue get resolved on your computer with the drivers install?
No the updated drivers did not resolve the sleep/screen hang issue a day after I did all the updates from your post I found the laptop unresponsive after leaving it open on my desk for a while.
I have been trying to isolate what causes these intermittent freezes, in all cases I think the screen was open this most recent time the laptop was on AC and sitting at my desk with the screen open. Again I do not think it had gone to sleep per say rather switched off the screen and does not respond. I have tried both keyboard and mouse as well as touching the fingerprint reader and repeatedly pressing the power button. None of these resolve the issue only holding the power button down to force a shutdown and then rebooting.
