RE: HP-12C Platinum won't turn off after screen self-test
Original test calc was 12C Platinum (China production):
S/N CNA02113887 C 2004 hP ChE - - 564Ah After your origin question, I also tested a Phillippines version: S/N PHA92004WC C 2004 hP ChE - - 564Ah Same results. Looks like it's a "feature"  !
