Today Windows 8 (genuine version) performed a Windows update. At the time my laptop was plugged into an external Samsung TV via HDMI. After the installation of the update it asked me to reboot the laptop, which I did.
Ever since that moment the build-in display of the laptop has been blank. It does turn on (I can see that the back-light goes on), but nothing appears on the screen. On the external Samsung TV Windows was showing, so the first thing I did was uninstall the latest updates that Windows 8 had installed. This did not fix the problem.
Then I re-installed the drivers of the on-board Intel video-card. This did not fix the problem either.
Then I removed the motherboard battery, rebooted the laptop, put the battery back, reboot the laptop again, to reset the BIOS. This did not fix the problem either.
Then I went back to Windows 8 (on the Samsung TV via HDMI), and I re-installed the drivers of the Nvidia graphics card that is also build into the laptop. During this process, the Samsung TV screen went black, and did not come back anymore after. I restarted the computer, but now I also cannot get the external display to work anymore via HDMI.
As a result now, I have a build-in display which shows nothing, and an external display which does not work, so basically a totally unusable laptop.
Just to be clear, the build-in display also shows nothing during the boot-up process, so I cannot get into the BIOS to do anything, nor format and re-install Windows.
Does anyone have any idea what I could try to fix this?
