I have a Lenovo g580 with windows 7 home premium 64 bit, whenever it goes to sleep, in whatever way, I get a black screen telling me that windows did not shutdown successfully.
I have completed a system restore to factory settings and downloaded and installed all updates. I have also run all Lenovo diagnostics to no avail.
I have changed the settings in power options, the bios has no power option.
I would appreciate any help
