Problem in short: My laptop display is not working; however an external monitor is working via HDMI. Interestingly, the touch screen capabilities still work despite there being nothing displayed. (The touch motions register on the external monitor because i have it set to 'clone display'.)
Long version: This past weekend, after a Windows update, upon the next boot, my display was no longer working. I get nothing; no boot screen info, windows login screen, nothing. I can use an external monitor, which I am doing right now, via the HDMI connection, so I am certain that my video card hardware is functioning. I just performed a full Dell diagnostics and everything passed. I have tried the following:
- Update to latest BIOS (A05)
-Update to latest Intel video drivers (receive error trying to install)
-Tried rolling back video drivers, but was unsuccessful due to (what I think) is inability to enter Safe Mode
-Perform a system restore to a save point prior to the last Windows Update (unsuccessful again, due to the fact that upon System Restore initiated restart, I cannot select options due to having no usable display).
At this point, I think my my display might have simply gone bad and I must get a replacement. I am under warranty still and plan to contact Dell directly to address the issue. In the mean time, are there any suggestions on other potential solutions?
Thanks in advance for any help or comments.
