I have a Acer Aspire 5720Z - 4171. The problem I am seeing is the unit operates fine with AC plugged in but if unplug the display goes very dark you can still see the imagees on screen but to dark to work with. It is the same if powered up on battery. Plug it in close and open the lid and and we are back to normal. All power and brightness setting are at max. Nothing in the BIOS the controls the screen brightness. Battery showes 100% charge. Not sure where to go with it from here.

Thanks for the help.

    Hi,

     The issue is caused by one of this two:

    - Battery problem ( need repair or to be replaced)

    - Hardware problem (battery circuit in the motherboard failed)

     

    We would suggest contacting technical support in your region for further assistance with this issue.
