I'm hoping to get suggestions on what may be causing this issue.
When I turn on the laptop, the screen works but there is no backlight. Then I connect a monitor, and that turns the backlight on. Then I can disconnect monitor, and use laptop normally until I turn it off.
Once it (backlight) came on by itself, once it came on after coming out of standby, and once it came on as if nothing was wrong straight away.
Any suggestions greatly appreciated. This laptop has been an absolute legend, i've had it for a few years and I'm extremely impressed with its resistance. It has been dropped while on from table height at least 3 times without any damage. It has survived a burst pipe leaking onto the keyboard for hours and then being turned on while wet - producing a nice electric burn smell. But I just dried it out and then it was good to go again. The touchpad left and right click buttons are long gone but that doesn't bother me too much. It's shabby but it works and I love it, it's like Jason Vorhees.

I gather that the display backlight does not come on automatically, but if you connect an external monitor the backlight comes on and will remain on after disconnecting the external monitor. It did come on by itself ,once when coming out of standby and once normally. It sounds as if it might be the display having some issues starting the backlight. Connecting the external seem to give it the kick start to work. You can run hardware tests on the display but it may need to be replaced soon.
