HP-28S Battery Door Message #1 Posted by John Limpert on 25 Oct 2003, 6:16 p.m. I recently purchased an HP-28S for my collection. I had a terrible time installing the batteries. It was much more difficult than on my HP-28C. Is there a trick to replacing the battery door? I'm afraid that I will break it next time.

Re: HP-28S Battery Door Message #2 Posted by CalcKidd on 25 Oct 2003, 10:01 p.m., in response to message #1 by John Limpert I often wondered why the 28S's door (and 19BII) was so hard to close. It appears the spring inside is either larger ot stiffer than in the 28c or 18C. Though not advisable, I was going to maybe remove some of the spring (just not sure how yet). :-(
