Windows 10 - Bluetooth stopped working.

Dell / Inspirion 7737
March 24, 2018 at 20:57:19
Specs: Windows 10, Intel i7 4500U
So, suddenly last night Bluetooth in my windows 10 laptop stopped working for no reason. The toggle switch in settings disappeared and the Bluetooth device in device manager has a small triangle on it.

I tried to reinstall the drivers and it says "The drivers are not intended for this platform" while it clearly states on the Intel website that those drivers are for 64bit windows 10.

Yes! the Bluetooth chip in my laptop is from Intel and I am 100% sure that I am using the right driver files.

Here is the device ID: USB\VID_8087&PID_07DC&REV_0001

I do not understand how can this happen that suddenly windows just discards the drivers it was previously using and was working fine. I checked in Dell Diagnosis and it says my Bluetooth chip is working fine so, it is a driver or windows issue.

This is totally weird and makes no sense to me!

"I tried to reinstall the drivers and it says "The drivers are not intended for this platform"


The "platform" in this case refers to your laptop, not the OS.

The correct drivers for your laptop's internal devices are provided on the laptop maker's website - - - they are the only ones you should be using - - not drivers from the individual device manufacturers websites.

I tried the drivers from Dell's website and they installed successfully but Bluetooth is still the same, identifies under other devices as "Unknown device". I did restart the laptop after installing the drivers.

This is the driver I tried: http://www.dell.com/support/home/ca...

Laptop's service tag: HLL73Z1

Any glitch can corrupt drivers. Also Win 10 has a knack of updating drivers.

Can we assume your computer model number is one of these?:
Dell Inspiron 7437/7537/7737

Always pop back and let us know the outcome - thanks

Do you know if your System Restore is turned on (MS forget to turn it back on after feature updates)?

If so you could see if there is a restore point dated just before your problem came along. If so go for it, your own stuff is not affected.

The other thing you could try is discharging the motherboard components, like this:
Turn off computer and remove power cord. Remove main laptop battery then hold the Power Off/On button down for at least 20 seconds. As you have now updated drivers it is unlikely to help but if the battery is easy to remove it would still be worth trying.

It's a non-removable battery but I think I can remove it with a screwdriver. Let me try.

Not worth busting anything - it's a bit of a long shot that it will help.

The restore would be the best option right now if available.

I tried a system restore as well as the motherboard power reset thing. Nothing helped.

When you did your System Restore are you absolutely certain it was a restore point dated before this problem came along? The reason I'm asking is that I would have thought it would have fixed a driver fault. This raises the possibility of it being hardware, although you seem to have covered that aspect.

Right now I'm about as confused as you are about this.

Pretty sure the system restore date was before this issue happened. I don't think it's a hardware issue because the device still shows up in device manager.

This is so weird!

It's still not working.


Edit: Just booted a live Linux distro and Bluetooth works/pairs perfectly fine there.

The Linux distro was a good move and indeed supports the idea that it is not a hardware fault.

You say you are "pretty sure" the restore was before this happened. You could temporarily try an even earlier restore point because they can always be undone if need be.
