Aspire 5742 screen blanking

This Aspire 5742 laptop has a problem where shortly after coming to the desktop, when booted on battery, the screen blanks and nothing will bring it back to life, requiring a forced power-down. It doesn't happen on battery
Power settings in Windows are "Never" throughout, both on battery and PSU for sleeping etc.

Try changing the battery with a spare and try booting. If the problem re-occurs, Try updating the drivers and hopefully it works.

Then quick work around would be to turn off your laptop and reboot into safe mode with networking option and try updating the drivers. Hope this should work.
while updating the drivers can help - don't forget to update the bios as well
