Hi dear friends...
my almost new hp 17bII, which i use very few and always worked very well began to have serius problems....
i fit it with new bateries yesterday ( i actually bought them for other calc) and it was working OK..i use the batteries a little for test a hp 12c and then i use the same batteries for my trusty 17BII (which already had worked with these batteries as i said)...but it´s not working well...in fact have a serious malfunction...as soon as i power it up..it shows the following message: STMPA DOPPIO SPZIO:
IT do appears to pass the selftest but as soon as it is recovered after this selftest returns again to this message: STMPA DOPPIO SPZIO: as waiting for a answer from the menu keys (which do not appear anyway)...i pushed the menu keys, the message dissapears but the things goes worst..the screen turned blank and do not work at all...if you wait a little and power it up again the cycle repeat...I would be VERY grateful if some of you could help me..it´s real pity to loose this excelent calculator...
