At risk of repeating previous posts - I am left wondering how Microsoft can get something as obvious as a wifi driver for an intel wifi card so clearly wrong, and still keep putting it back on my device during a blacked out boot screen even after I have tried to disable updates.
My scenario - Win10pro, standard software only was working fine until end of Feb, some update left network adapter in device manager 'working properly' but no wifi networks as device not connected. I download Intel device driver utility that uninstalls existing driver v20.n, run again to install Intel's version 19.n and wifi is back working.
Now here's an odd thing I did not know before.. according to Gigabyte support, a windows Shut down does not really shut down your laptop, instead it goes into a deep sleep state so when powered on it boots quick and without the BIOS screen prompt. However, if choosing Restart (the Win10 description for shutting down the laptop is exactly the same as shut down) but this time it really does power off the laptop and the next power up does indeed show the BIOS select option.
BUT - the screen stays blacked out for at least 5 minutes (sometimes nearly 10 minutes!) and at first I suspected a hardware fault. Patiently waiting longer than an old slow 5400 fragmented sata drive would take to boot and the logon screen eventually appears - pressing any key does not activate the pwd cursor, only ctrl+alt+del or the left mouse button does that, and guess what - the wifi driver has been updated (no LAN cable btw) back to v 20.n and wifi no longer works.
How.. how does Microshaft even survive? No acceptance of this issue. Oddly, all previous system restores have been wiped and only option offered is.. re-install a clean Windows restoration. Really?! What have they done, clearly I am missing something here, like a reliable operating system on an 18 month old latop.
Anyone else experienced the blacked-out screen for 5 minutes on Restart?
