Alpha smart 3000 won’t turn on
Hi everyone. I just received an AlphaSmart 3000 that I bought on eBay. It came without batteries so I put some in and then played with it for a few minutes. It seemed to work fine. I’ve just come back to it after about half an hour and now it won’t turn on? I’ve tried taking the batteries out and putting them back in. It’s hot today in London, England but not so hot that electronics would struggle. Is there some fragile part somewhere that needs a jiggle?
Thanks in advance!
EDIT: I've discovered that the issue is the on/off key. It is fussy. I have to bash it to make it turn on and then it seems to accidentally trigger itself while I am typing (I'm a bit of an aggressive typist).
