The green and orange charging light flashes back-and-forth constantly
When I’m charging the calculator the green and orange light flash back-and-forth constantly, The calculator won’t even turn on, what’s my problem?
Cette question est-elle utile ?
My calculator does that too it’s like blinking black and green lights would it be the battery or something else that can be fixed ?

@la luce I'm not all that familiar with Casio but a battery replacement would be the first thing I'd try.
