After running my B570 (1068) with an extended display, the unit went into hibernation. On wake-up the laptop screen is indecipherable garbage. The second display will run to show BIOS startup but then reverts to the built-in screen - which is illegible. Toggling the F3 key does not get a good screen.
I read another post suggesting this is a hardware failure. What parts have failed?

Welcome to Lenovo Community!
I’m sorry to hear about the situation, please let me know if the issue persists even after re-installing the display driver in your B570 Laptop.
Hope to hear back soon

Can you please provide instructions on how to reinstall the display driver when I cannot read the screen?
When the machine boots to windows, it defaults to the primary display (which is corrupt) and the second display goes black (power saving mode).

Just to add; when I boot from a windows CD, the second display is temporarily usable (presumably duplicating the primary display instead of extending it) and I can access some Widows repair options. An attempted rollback to an earlier point was however, unsuccessful.
When the machine boots through to Windows, the second display turns off.

In that case, please try to turn ON any one of the display and check re-installing the driver and this is not possible. The only available is option is to contact our Technical Support for further Assistance to get the details of the nearest Authorized Service Center to get the issue analyzed.

I was able to get the machine to duplicate displays (instead of extending). I downloaded the latest Intel drivers from Intel and successfully reinstalled them.
The problem is still unchanged - the built-in display is unintelligbly distorted and the second screen performs normally. Does this signal a hardware problem ... inverter or lcd display?
