Got new Lenovo system, (i7, 3 series chip (previous i7 chip)). Came with 8.0, upgraded to 8.1. No problems with the upgrade to 8.1. Now, occasionally, (when I leave and come back), the screen is black and nothing besides a system reboot will get my display back. I still have the old system, and can see and get to the C drive on the new system (so the new system is still running, just the display is blank). No cursor, no nothing...nothing gets it back. This is intermittent, some days it happens, some days it does not. I always have to reboot. Somewhere (I don't remember where right now (power settings ?), I set the system so that it does not shut down (when this had happened a few times...in case it was shutting down).
I have searched online, and while there is a lot of comments about a blank screen when updating (or right after updating), to win 8.1, no one else seems to have my particular situation. I have looked at (downloaded the software, but did not registered, several driver update programs, but also have not downloaded the drivers that they suggested). One only suggested two drivers, the second 14 drivers, the third 18 drivers. Two of them have pointed to multiple Intel chipset downloads and I got a feeling that this related to the 3 series i7 chip (which could be the problem?). Anyway, do I need to be concerned about the order of the driver updates (one says that it does some updates at the same time and in the right order), etc. Should I register (buy) one of these driver update software products (which one), or should I download and install myself, without regard to order?
I am actually on my old system right now. When I post this, I will switch to the new system and add a document that shows the recommended drivers.
