I have been trying to find the error with my wife's Acer Aspire 1360.
Laptop can be turned on for hours (sometimes just minutes) and then suddenly the backlight dies, screen still visible there in the darkness.
To solve the problem temporarily I can reseat the inverter plug from the motherboard, a 2x15 pin connector with black, red and green wires (very thin). Not all places are used in the connector, some are empty.
I bought another inverter, including the wire, that didn't solve the problem. I have tried hooking up a CCFL from another screen, same behavior. So neither the tube nor the inverter seems to be the problem. Possibly the newly bought inverter had the exact same problem.
There is no flicker at all, it just dies and only way to get it going again is to either pop and plug the inverter connector (either end works but the one one the motherboard is easiest to reach) or restart the computer.
Is it likely it's caused by software? I have tried shutting off the dim LCD while running from battery. I have the same troubles weather running from battery, running with battery and PSU or just PSU without battery hooked up.
There are no later BIOS updates AFAIK.
Does anyone have any ideas what else to check or measure?
Can I hook up the inverter on my lab workbench without the computer, any idea how?
Do I have to disassemble the laptop completely to check it?
Knocking on strategical places or the whole computer has no effect, either way, it doesn't cause the light to go off nor on.
I was considering an LED upgrade but it's a lot of money to spend on this old computer. Maybe a LED-mod a'la Ben Heck is a possibility...
Inverter is marked V0210713104 A53 S127177 19.21064.001 Rev.1B , it has seven LEDs that indicate network, it's on, sleep mode, hdd, battery, caps lock and NumLk. All these LEDs seem to work fine during the blackouts.
Are we perhaps in search for a breaking electrolytic cap? :-(
I was hoping I wouldn't have to disassemble it completely...
