Would it activate Intel Graphic driver to flash BIOS with USB-stick?
When you boot do you see the Acer logo or a spinning circle? If not then try powercycling the computer. Pull the main battery and power adapter. Hold the power button down for 30 seconds. Replace the power adapter but not the main battery. Reboot.
Did the computer come pre-installed with Windows 8.1? Do you need any data from the hard drive?
Sometimes a dead CMOS battery will prevent a computer from booting.
I see only black screen on both laptop screen and external screen connected with hdmi/vga when computer boots after powercycling.
I can hear laptop boot just like before Intel driver was inactivated.
Laptop was pre-installed with Windows 8 and then upgraded to 8.1.
Microsoft support was in the process of helping me remotely upgrading Windows to version 10 due to error 0x8007001f.
This support has been paused due to inactivated Intel graphic driver.
I've already made backup of user data on another partition on same laptop. I also have access to user folders through my local network if xtra backup is needed. Most important data is on another partition on same laptop. A problem with installing a fresh Windows copy is that I do not have the key, although my installation is legal but pre-installed. Making a repair would be difficult on a black sceen. I've tried booting a Windows 8.1 installation DVD but all screens are black.
