T540p Internal Display stopped working

My internal display just stopped working for no reason with Windows 10. The external monitor still works fine though.

I checked the Device manager, the internal display had disappeared from the Monitors section, only my external monitor was listed there.

It had happened twice. I brought the display back the 1st time after I uninstall the monitor driver and re-installed the latest driver from Lenovo website, but this time it's already with the latest driver and the same trick did not work.

Luckily I still have a clone image of the system with Windows 8.1. Once I switched back to Windows 8.1 the internal display worked fine so I think it has to be a driver issue.

The display adpater is Intel HD 4600. The internal monitor is the original HD display that came with the laptop. Please help.

Hi Paulgti,

 

Welcome to Lenovo Forums.

 

Consider updating the Intel HD Graphics from the Intel Website. Also, check if display fine when you connect with external monitor.

 

Please update the following

Chipset

BIOS

Firmware

 

Let us know how you get on.

 

Regards,

Shashi

Thank you Shashi. I've downgraded my system to Win 8.1, but I'll try those update after I update my system back to Windows 10.

Windows 8.1 is running fine on my T540p for now. I didn't want to take the risk upgrading to Windows 10 unless Microsoft make me. But at least I would know what to do if I ever encounter this issue in the future.
