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.

Don't have one i' afraid. Client wouldn't buy one as a gamble

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.
