Question Lenovo Flex 2 Video stops after Logo

[ITweeks]

Hello All,

I have a Lenovo Flex 2-15 that will display video on the built in screen when in BIOS settings or at the logo screen. But once Windows 10 begins to load, it cuts off. Then, the only way to see what is happening is by connecting an external monitor, putting it into standby, then bringing it back from standby. Then video will display on the external monitor. I have re-imaged it with Windows 10 and installed all updates, but the problem is persistent. NOTE: Ubuntu runs fine with built-in display including touch features.

I've had a similar problem before with a Toshiba where I had fixed it by installing a modified version of BIOS. But I don't remember where I found it at. I suspect that I could fix it in a similar way, but I'm looking for suggestions.

Laptop: Lenovo Flex 2-15
Model: 20405 (from sysinfo32)
BIOS: A0CN31WW

try the hotkeys
windows + P

Load default settings in BIOS, save and reboot

try uninstalling video drivers in windows safe mode (eventually use ddu uninstaller)

Awesome, thanks for the help. Deleting the generic PNP display driver worked temporarily, but then it disconnects after about 2 minutes. Then behaves exactly as before. So how do I block that driver? Just disable it?

Try installing the graphics driver from Lenovo:

eventually this Intel driver:

I've tried all that. It didn't work.
