Hi ashu2000 ,
Welcome to the Community Forums.
Checking on the Lenovo supported systems list for Windows 10 Upgrade , "not listed, it hasn’t been tested for Windows 10 upgrade and is not supported. " for the G570 .
Same reasons why on the support site , drivers for windows 10 is not available.
There are claims that it works ok but some have reported devices and apps not working after the upgrade.
You may check related threads here .
Would there be any yellow or black down arrow marks on the device manager .
If that is the case , then you may want to try checking the hardware ID to download specific driver directly from the manufacturer if the Windows 8.1 version driver would not help.
On device manager , you may also use built in drivers in Windows 10 doing upgrade drivers and, browse on this pc , let me pick option, and choose recommended ones on the list .
Hope this helps.

I tried each of the suggestions and stopped short of hardware search!
There are now yellow or black downward arrows on device manager. My machine has Broadcom bluetooth 2.1 USB. Can I download 4.0. driver? And if yes, where should it go?
The last line about 'let me pick option' is not understood. Can you give more how-to help? Thanks.
Incidentally, my laptop is G470 (not 570), and I am a chemical engineer using computer mainly for data analysis and training in ISO 9000- so not really an advanced user of computers. I think I should not have downloaded Windows 10 in the first place, and now I am scared to go back to the previous version - what if everything just conks out!
I am happy to be in this forum. I am sure I will get help.
Thank you all.

Hi AJ ,
G470 is not listed compatible for Windows 10 , it hasn’t been tested for Windows 10 upgrade and is not supported.
Thanks for the correction.
Moving forward, so it seems that the device manager was not able to detect the Bluetooth device in Windows 10 .
There is no option for us to upgrade and let me pick , similarly no yellow marks means no driver issue since the bluetooth was not detected.
What is the message when you tried installing the driver?
Was it working /detected before in Windows 8 ?
Was the Bluetooth enabled ?
Let's try power drain and BIOS default reset.
1. Turn off the pc and unplug the ac adapter and remove the battery (page 31).
2. Press and hold down the power button for 15 secs and connect back the battery and charger.
3. Turn on the pc using the One key rescue button (item5 page2)
4. Choose BIOS set up and press F9 (load defaults ) and F10 (save and exit)
5. Check the device manager again for bluetooth device (show hidden)
6. Try to install the Bluetooth driver.
WIndows 10 patch updates is cascaded by Microsoft every month and would also be suggesting updates for drivers too as optional where you can check if bluetooth compatible driver is available.
I am also on the same situation as yours, knowing that sooner or later most pc would soon be Windows 10 and the free upgrade that Microsoft have is until june 2016 .
With a Lenovo pc there is always ways to go back to Windows 8 using the factory reset but would delete files.
I would help a lot and ease your worries if you have a back up copy of your files on a separate storage (external drives) , you may even clone the entire Windows and everything too at the same time.
Check with your IT guys on their suggested software to back up and even clone similar to this list.
Alternately a cheap BT USB adapter similar to this can always do the job .
Update us how it goes.

I made an unsuccessful attempt to install Broadcom Bluetooth 4.0. When it was ready to install after downloading it asked me to uninstall present version. I had to cancell installation. I did all that. I checked and found device manager does not show bluetooth (the old one - 2.1). Then I tried to install the new version but it still said uninstall old one. Then I stopped, and rebooted the computer. And then found my old bluetooth back in place. And still not recognizing my android phone!
Someone please help.
PS: And even after installing 4.0, what if it still does not discover nearby bluetooth devices ?

Hi ashu2000 ,
If the Bluetooth capability is a need for you rather than just Window 10 upgrade , you can always go back to the original certified Operating System intended for the pc .
Else you can always use alternative option cited above .
It would always be best if you have a back up of your personal files .
