These equipments use a sbc492 by Aaeon motherboard, and usually they shows a message like "Cmos battery Low".These motherboards use an RTC M48T86PCI with a internal lithyum battery, and just replace that component.Other problems may occur, like damaged slots, and or oxidation, but generally the 486 architecture is a huge way to work,Only clean change the memory(dimm 128 x 100mh)and enjoy.A simple way is a replacement with a new one by Intel, still easy to find in some inventorys, i have many in USA who can suply.

hope to solved

This is a brand name, not a specific device and model. That said, here is a page describing mode switch in the setup screen using the touch screen for a specific device. I assume a touch screen would have an icon for turning a device off.

It sounds like the backlight of the LCD display is out. The Image is still being displayed there is just no light to illuminate the image. Try shining a flashlight on it (Put the light right against the screen) and see if you can see what's on the screen. The display is fairly easy to install but I do not know where you can purchase one directly.

The battery is soldered to the CPU. People from Zeiss Germany said that it needs to replace all the CPU. Now a days there is no longer spare parts for that instrument. I recommen you just change the day and time each time you turn it on

The two most common problems when trying to find a blind spot are: A.) Forgetting to patch the eye, and B.) Choosing the correct eye in the machine itself.
