Bluetooth gets turned off on its own, so you can't see your settings anymore.
Bluetooth gets turned off on its own, so you can't see your settings anymore.
I bought this Dell Inspiron 7415 with Windows 10 that is pretty new. It also has all the Dell driver updates installed. But sometimes when I turn it on, my Bluetooth stuff won't work at all—the mouse and keyboard don't show up. Even in the settings window, it says Bluetooth is off. There isn't a way to fix this; the option just disappears. In Device Manager, it doesn't list up there either.
I tried a bunch of fixes: running the built-in troubleshooter (which told me my computer couldn't do Bluetooth, but that's wrong), turning off fast startup, and uninstalling the driver from settings before reinstalling it on Dell's site. None of those helped. But after I stopped trying to fix it for a while and just left the laptop alone, it suddenly worked again! This has been going on many times.
Yesterday, shutting down and restarting actually fixed it last time. But today, doing that same thing didn't work. I have pictures from my attempts but can't show the Wi-Fi network because Imgur blocks them. So I'll leave a comment once I figure something out.
Do you have a Dell Inspiron 7415 running Windows 10 that is really new? Maybe it has all those Dell SupportAssist fixes and the newest BIOS version? Maybe you can try taking out the Bluetooth thing from Device Manager, then without turning off or restarting the laptop, manually put in the latest Bluetooth driver. To do this, right click on the installer and run it as Administrator. If that doesn't help, try putting in new chipset drivers too and then try the Bluetooth adapter again.
Yes, BIOS is also a thing. Dell SupportAssist handles most things. It's just the built-in Bluetooth chip; I don't have an adapter to use right now. I tried that way before but didn't run as administrator, so next time I'll do it differently. Would the chipset drivers be on the Dell website too? When I turned my laptop back on, the problem went away by itself. I will try all these steps if this thing happens again.
It's a built-in Bluetooth chip inside my phone, so I don't need an extra plug. Look at that little slot on top of it labeled with WLAN? That's where your wireless adapter goes in. I didn't mean to say you should grab a dongle, more like the little card you put into the slot. Maybe the computer or operating system is glitching, maybe my drivers are acting up, or both. Or worse, the adapter is just saying goodbye to the phone.
It just seems like it happens when I plug in an HDMI cable and use my laptop as a screen for a second monitor, but with the laptop turned off. Or maybe it's more likely if I do this while the laptop is off. I've found that holding down the power button to turn it off and then back on usually fixes things; no other way to shut it down works better.
