HP 35s won't turn on

Thanks for the suggestion. Unfortunately, that didn't yield any results either. It seems as if I press random keys, sometimes I get a brief display on the LCD that shows most or all of the indicator and notification icons, but it doesn't last.

Maybe this is not worth worrying about, now that I have a replacement 41CV that works just fine. Still, it is frustrating.

Any point in disassembling the calculator to see if something is loose?

Maybe I should just donate it to someone who needs parts.
