Re: fix an HP 41C tall key - fullnut Message #7 Posted by Damien MATTEI on 14 Oct 2008, 11:22 a.m., in response to message #6 by Randy Sloyer
evrything looks ok,all screw are tighten correctly,opening it and disassembling show no damage, the 4th port sometimes seems dead but with some flex on case works again,the calculator power on only if i remove the batteries for hours or invert the batteries for 1-2 minutes, so i leave only 2 batteries inside and 2 other stay in case,when i use it i put in place all the batteries, power on it , execute 'on' command to keep it running for hours ,after i stop it with power off button (or 'off' :-) ) and store it removing 2 or all the batteries (i remove only two because i can place only two batteries in case as i have a card reader ,the two unused batteries take place in the hole on the card reader where HP il module can pass by ,in paper too to not scratch anything), that's all...
