Enabled CMS in BIOS and now no display signal to the monitor

2020-08-04, 8:29 AM

HI All


I have enabled CMS in the BIOS to allow legacy boot on a M75s-1 Desktop Think Centre type 11AA and then it will not display anything on the screen.


No signal is being sent to the monitor (orange light on power button) which is connected via VGA, I have also tried the displayed ports and we have no signal from them either.


I have already sent one back to lenovo for repair and they return it working but CMS is no longer an option in BIOS on that one but it does legacy boot.


I have 109 of these PCs to re-image via legacy network PXE boot. These are brand new out of the box.


Please help........
