Need help - HP 17BII cleaning Message #1 Posted by Selim on 15 Apr 2005, 7:27 p.m. Hi all. Has anyone successfully opened an HP 17BII to clean it? I bought one used from a fellow locally, and it works, but some of the keys stick, or need several presses before they work. I would like to try and open and clean it to see if that helps, but I cannot figure out how to get it apart. Thanks in advance.

There are lots of threads in the archives about opening and cleaning keys. I would start by removing the batteries and dipping it into an ultrasonic cleaner. If you dont have one of those, I have used distilled water with good success. I drop the whole calculator under the water, press the keys and clean with a toothbrush. Shake it out, towl dry and then let it air dry for two days before I but the batteries back in. This method goes against common sense, but I have never had a problem with it. http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv014.cgi?read=69775 http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv014.cgi?read=67188 http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv014.cgi?read=55509
