I have had a HP 12C for a while and found that when I enter digits/numbers they seem to multply eg 4444 or 7777 and then have to clear andrenter again. The other question I would like to reach for a reply is that I would like to PURCHASE another HP 12C online but the website shows these are currently Out of Stock and has shown this for quite a while - has there been a recall? Can anyone enlighten me with an estimated date when they maybe available online for purchase?
Firtsly, thank you for your comment. I did carry out your solution and removed batteries etc for 24hrs this seemed to remedy the problem for a short while, now I find its back to what it was previously doing that is eg press 5 >555 just multiplies, so would really like to replace my 12c rather than send for repairs. Then link you provided does take me to the Product #12C#ABA to order but as usual just displays this is [out of stock] and has been like this for quite some time.
So I am disappointed with HP having such a great product but can't purchase due to the lack of stock. I hope they are taking note of my comment/s and commence production and supply of the HP12C 12C#ABA, thanks Loris_xi
