I was watching the Mayweather vs McGregor fight, streaming from my laptop to my Samsung tv using an HDMI cable.
Laptop is Dell XPS 15 9550.
When the fight was over I simply unplugged my HDMI cable from the laptop when all of a sudden my laptop flashed black but never turned back on...?
I was thinking this had something to do with the "extending" or "duplicating"' the laptop to the TV. Thought maybe I unplugged the HDMI too quick for the laptop to register that the display should now be on the laptop instead of the TV?
Well it took me a while to figure out.
I was able to run diagnostics which came back clean.
I held the power button in and turned it off.
When I turned it back on it said "No Boot Device".
I then tried removing the Hard Drive and Memory to see if it was not seated properly or something.
No luck.
I then looked into the Bios...
Turns out, SOMEHOW!? the boot mode was changed from UEFI to Legacy!
How that happened, I really dont know... Nothing was changed on the laptop.
Anyway, I was able to get back into Windows.
Once in Windows, I tried to play audio and nothing would play.
So I looked at the Audio drivers and it listed "Realtek Audio Drive" and "High Definition".
I did what I normally do when there is a driver issue, I uninstalled and reinstalled the Realtek.
Once I did this, All *** broke loose.
Now I cannot get Realtek back!!! Been fooling with this for 8+ hours.
I called Dell and they were remotely connected but couldn't figure it out.
They are saying the Speakers are bad. I really don't think its hardware related.
I feel if I reinstall Windows, the issue might be fixed... But I am kinda putting that to the side (because I formatted recently in March).
So I have Dell coming to fix the laptop speakers in a few days.
Does anyone have an idea what might be the cause?
I just reinstalled the Video Driver because one post was saying something about HDMI uses Video Drivers. Havent checked yet but if I don't respond back with it worked, consider its still broke.
Any help appreciated!
Thanks!
