After removing the motherboard assembly for painting the housing my calculator did not power on at all. Ended up pressing random buttons and it powered on and works!

My used 84 plus silver kept shutting down after 3 seconds after upgrading the OS. Removing the AAA as well as the backup fixed the problem. Hoping the fix stays.

what if as soon as you cut it on you can't do anything no matter what button you push? The cursor isn't flashing and i can't turn it off it has to cut off on its own. How do i fix this

My screen turns on and my cursor blinks but after that, no buttons are responsive and it occasionally changes screens to the window screen. I have to remove a battery to get the calculator to turn off. I have no idea how to clear my RAM of memory reset. is there any way to remotely control your calculator from your computer?

I don't know where I put the charger that came with the calculator. Can I use a different wall-charger that I found? Or will this mess up the calculator?

I'm unable to do a screen capture. I get not responding on the store and then the following error message 'TI ScreenCapture - Error getting screen shot' OK. When I click on the TIDeviceInformation Icon, I get a response with all the device details.
