Bluetooth is not working on windows 8

What OS were you using when you upgraded? If you were using Windows 7, you could try to download and install the Windows 8 driver for the camera. These will often work under Windows 10.

Lenovo do not have Windows 8 bluetooth drivers on their support site.
You could try loading the WIndows 7 drivers (Broadcom Bluetooth Driver for Windows 7 32-bit or 64-bit)

Looks like theres is a problem with the operating system already. You might need to restore the computer back to the factory state. Turn off the computer then press the button that sits beside the power button. Follow the on screen procedure to restore the computer.

The same model ThinkPadcan have different types of network, video and audio drivers and unless youknow exactly which one is installed in your ThinkPad, you need to download allthe drivers and install each driver until you find the right driver. When you download thedrivers, write down the device driver and it's file name so you have a recordof which driver you are installing and which directory the unzipped files arelocated on your hard drive. Go to the IBM/Lenovo WEBsite - support/download page and download the latest Windows device drivers foryour model computer, Use this link: - http://www-307.ibm.com/pc/support/site.wss/product.do?template=%2Fproductselection%2Flandingpages%2FbrowseByProductLandingPage.vm&sitestyle=lenovo&brandind=10&validate=true

Just go to the Lenovo download center and see if they have bluetooth drivers for your laptop.

Hi raj,
I see that you are having a Bluetooth issue finding he option sending and receiving Bluetooth transfer options.
On your system whichever windows you may have you can see Bluetooth,

• Click on Start then click on All Programs, look for accessories
• Click on accessories it should show you the Bluetooth icon under Accessories if you click on it it will give you the option to send and receive using Bluetooth.

I see that you installed the driver for your Bluetooth to see if it installed properly check device manager, you should see Bluetooth under Network Adapters, if it's not there then the installation was not successful or maybe it just did not install correctly, try reinstalling again.

• You can also try download an application that can utilize your Bluetooth device for example Blue Soliel that is a good Bluetooth Application that I personally use, you may just need to purchase the program online to be able to use the full functionality of the application.

I hope that his will be helpful regarding your concern, have a nice day.

PLEASE INSTALL THE PROPER DRIVER . SEE THE LINK & DOWNLOAD LENOVO G460 BLUETOOTH DRIVER.
