Message-ID: <2359@gmu90x.gmu.edu> Date: 21 Nov 89 20:24:49 GMT Organization: George Mason Univ., Fairfax Va. Lines: 22 In the very near future, I will be posting an article giving in-depth information on power consumption statistics for the HP-28s. In it, you will find many interesting things. Here is a preview: A while back someone posted an undocumented storage mode for the calculator; if you press on-enter-backspace at the same time, the calculator will beep and shut off. Even the internal clock stops! When the calculator is normally off (NOT in storage mode) it draws 13.5 uAMPS. In "storage" mode, it draws 106.2 uAMPS!! This is 7.8 times the current drain! So what is "storage" mode really doing? Stay tuned... ----------------------------------------------------------------------------- Bob Peraino UUCP : uunet!pyrdc!gmu90x!peraino George Mason University INTERNET: peraino@gmuvax.gmu.edu UCIS, Thompson Hall, rm 2 <- BITNET : peraino@gmuvax 4400 University Drive \ PHONE : (703)-323-2549 Fairfax, VA 22030 \- Yeah, they put us in the basement, too. -----------------------------------------------------------------------------
