I have tried without luck to pry open my 15C calculator. I want to clean the LCD display screen and glass cover. Any help would be appreciated....as the manual is no help at all. Thanks, -- = Marc Tamsky 6600dtam@ucsbuxa.ucsb.edu 6600dtam@UCSBUXA (bitnet) =

This will certainly void your warranty, but look for screws under the rubber feet. -- Bruce Stephens

Peel one off and look. The 41C is like this. The 28 though doesn't, apparently it's glued. I never could open it so I X-rayed it. Very neat inside! (N.B. obviously any warrantees that might still be in place would be voided be opening (or irradiating (!)) it.) 8-{) Jeff Gruszynski Santa Clara Sales Hewlett-Packard

Ok, I've managed to open my 15C, by removing the screws under the feet. I've voided my warranty, which ran out a long time ago.... But now, I'm tring to get to the lcd screen and glass cover, but I've been unable to remove the pc board. (Its really pretty, all gold traces!) Anyone know how to remove the pc board to gain access to the lcd array? Thanks -- = Marc Tamsky 6600dtam@ucsbuxa.ucsb.edu 6600dtam@UCSBUXA (bitnet) =

Unscrew them. :-) As far as cleaning the LCD screen, you will probably have to pry the display up and stick a Q-tip in to clean it. This is tricky, so be careful! I have opened my 16C to speed it up, but I never tried to get under the display. Of course, I have to state the obvious. OPENING YOU CALCULATOR VIOLATES ANY WARRANTY, AND THIS IS NOT AN ENDORSEMENT OR ENCOURAGEMENT BY HP TO CLEAN YOUR CALCULATOR DISPLAY. >Thanks, > Your welcome. | Ken Sumrall | Internet: ken%hpda@hplabs.hp.com | | HP California Language Labs | UUCP: ...!hplabs!hpda!ken | | "I'd stomp desert dope heads for some gas in my moped!" - Bill the Cat | | "What a stupid world" -Calvin (speaking to Hobbes) |

HP hides the screws under the rubber feet! Just use a sharp knife point to peel the feet off. They can be re-used if you are careful. Be careful of ESD. If you don't know what ESD is then don't open your calculator. There are two basic designs for the internals of your calc, depending on the vintage. Either way I would suggest using a can of compressed air to blast away the dirt. Be careful, your are on your own. John McVey jmcvey%hpbslq@hplabs.hp.com
