I guess this probably points to a loose connection or something, but this is good enough for now. I don't need the advanced menus very often, but now I can get to logs and shut it off when I am done. The problem then is that there is a rubber support inside pushing the keyboard connector flex onto the PCB, this rubber tends to deteriorate. Here is a thread that discusses the problem: http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=151696 If you have a wish to try to repair it: here is a guide to opening: http://users.ju.edu/hduong/open/ and for repairing: http://users.ju.edu/hduong/repair/ (about halfway down see "keyboard connector" and "Rubber Under Keyboard Contacts" which is the bit that has to be replaced). (Note: the SX shown in the links above is physically the same as the GX) Someone's temporary fix without opening the calculator: http://h30499.www3.hp.com/hpeb/attachmen.../HP42S.jpg (At least the programs can be saved before dis-assembly). Best regards. |
