Re: How to enable the bluetooth after disabling it.

Hi random68934,

I was asking about bios because i read somewhere that the model 470/470 fn + f6 and could not be used to turn off the touchpad. But it can be fixed with new bios and synaptics driver. Therefore i was thinking whether you may want to try the bios update.

 

Anyway, i do not have Y series here with me but i have a U550. When bluetooth turned off, device manager wont show the bluetooth compoonent. Even if i used the option to "show hidden devices", bluetooth just doesn't appear.

 

However, this bluetooth will show up in device manager as soon as i enabled bluetooth by Fn+F5.

 

My suggestion is to install

  • Lenovo Energy Management in order to have the hotkey(fn..) works. The Lenovo Energy Management has a package to enable hotkeys.
  • Bluetooth driver
  • wifi card driver

 

Why wifi card driver? Reason being when i hit Fn+F5, the message box which allow me to enable/disable bluetooth has an option to enable/disbale wifi too. The title of this message box is wifi settings. Therefore i think it's better to try wifi card driver as well.

 

Hope this helps.

Re: How to enable the bluetooth after disabling it.

No I could not activate bluetooth because I disabled it. I never installed any drivers. This is what I need to know. I need to basically reinstall the driver. When i try it says it cannot find the bluetooth device.

Re: How to enable the bluetooth after disabling it.

First of all, have you unistalled the Lenovo Energy management ? as that could cause the FN+F5 not to work, only normal other thing that most users encounter is this switch shown here

They turn it to the LEFT, being turned off, that way all wireless devices are disabled, please try wickle it left and right 1 or 2 times, leaving it in the RIGHT position ( just as in the photo ) and then press and hold FN key while pressing down the F5 key, that should bring up a program called "Lenovo wireless device settings" and there in the middle you should have Bluetooth,  and it should then say OFF in the middle ( under current status ) and ON in the right side, click that likke green dot in the right next to the word ON, and Bluetooth should now be turned on.

 

Hope this help, please let us know.

I love helping people, support engineer.

Re: How to enable the bluetooth after disabling it.

I tried the fn+f5 after enabling lenovo energy management. I did not uninstall it. I disabled it from starting up. I tried fn + f5 and was able to turn on bluetooth. Thanks to all of you for your help. I really appreciate it.

Re: How to enable the bluetooth after disabling it.

I actually have one more problem. I was able turn bluetooth "on" after enabling Lenovo Energy Management but now I still cannot access bluetooth settings. I think this is because I uninstalled the driver when I was trying to see if reinstalling works. Now I am  trying to install the driver and it says "please plug in or turn on you bluetooth device." Do you guys know what to do about this?

Re: How to enable the bluetooth after disabling it.

Bluetooth also does not show up in control panel and is not recognized as a device in device manager.
