Updating dell bios ubuntu 9 10

Rated 3.87/5 based on 508 customer reviews

I want to disable Bluetooth on my laptop running Windows 10 Pro x64, but I have a problem: the option to do so is missing even though I know that it was previously available.

Try to connect the LCD screen to an external monitor.Look at the LCD screen very closely and check if you can see a faint image on the screen.It’s possible that the LCD lid close switch stuck in the “closed” position and the backlight stays off even when you open the LCD screen or turn on the laptop.Once you restart, you will find the toggle in the Settings app.You will also find a new toggle button for Bluetooth at the bottom section of the Action Center (may need to Expand that section to see it).
