Hi @redbullet ,
Just verifying that the Nvidia GPU is being detected in BIOS as you said “ Switching Integrated/dedicated GPU settings in BIOS in hope of reactivating it or something.” Does this mean that it is always there in BIOS even though it usually isn’t in Windows?
I realize that you said that you updated the BIOS but was wondering if perhaps there may be some corrupted data in BIOS that is causing this and the update to the BIOS wasn’t in the area of the problem.
Convoluted way of saying that you try a full power refresh to reset the BIOS back to its factory default condition. Worth a try at least I think.
Here’s the procedure:
a). Turn off the laptop if on and disconnect the charger if connected.
b). Open the laptop and disconnect the main battery from the motherboard. You don’t have to remove the battery, just disconnect it.
c). Unplug the [https://www.ebay.com/p/1565172691|RTC battery] (example only to show you what it looks like) from the motherboard. Here’s the [https://download.lenovo.com/consumer/mobiles_pub/ideapad_y700-15_17isk_15acz_touch-15isk_hmm_201510.pdf|hardware maintenance manual] for the laptop. Go to p.59 to view the procedures to remove the battery. Hopefully you don’t have to complete all the necessary pre-requisite steps just to unplug it from the board.
d). Press and hold the laptop’s Power On button for a full 30 seconds and then release.
e). Reverse the above procedure to re-assemble the laptop.
Once the laptop is re-assembled, connect and switch on the charger and then turn on the laptop and when it has booted etc check if the Nvidia GPU now appears OK in Device Manager.
I’m not sure but there ''may'' be a message when you first turn on the laptop about the date and time being incorrect. This is normal as the BIOS has been reset. Once the date and time have been corrected the message won’t appear the next time that the laptop is started.
