EOS 1500D Disable auto power off permanently

[kesavparu]

I have been facing an issue with EoS1500D camera. Below mentioned the test setup and issue.

Setup: I am using a dummy battery (ACK-E10) in the battery slot of an EOS 1500D camera to keep the camera (and display) continuously ON. I have disabled the auto power-off feature in the settings, but after 30 minutes, the camera still goes into auto power-off mode and the display turns off. I tried turning off and then on the ACK-E10 power adapter, but the camera's display did not turn back on. Could you please assist in ensuring the display stays on, even after cycling the power?

This behaviour is by design and it is mentioned in the manual on page 185 where it says:-

Even when [Disable] is set, if the camera is not used for 30 minutes the LCD monitor will turn off automatically. To turn on the LCD monitor again, press the <DISP> button.
