Can you carry it in a backpack or luggage with the unit turned off and still be able to turn it on days later without replacing the batteries? 2. Keyboard: are the keys loud and hard to press? Thanks in advance. ▼ V-PN Posting Freak Posts: 785 Threads: 13 Joined: Jan 2005 04-06-2005, 10:48 AM days later? - rather months later! 33s keys are better, but the 17bII+ are ok.

Using L() and G() does not return expected results. For example, L(A:LN(X+1))+Y÷G(A) If I put X=3, then Y returns 0. (when it should return -1.92) If I put any number for Y, X returns SOLUTION NOT FOUND (Example: if let Y=-5, I should get 8.35 for X) Now for something really weird... L(A:LN(X+1)+Y÷A If I let X=3, then I get the Y=-1.92 result. BUT If I try to solve for X, I get BAD GUESS; and if I try to solve for A, I get 0. I am not sure if this is worth justifying replacing my old one and spending another \$99. ▼ V-PN Posting Freak Posts: 785 Threads: 13 Joined: Jan 2005 04-09-2005, 03:52 AM What happens if you change the order? Y÷G(A)+L(A:LN(X+1)) [VPN] ▼ Eddie Shore Senior Member Posts: 260 Threads: 40 Joined: Jan 1970 04-09-2005, 08:23 AM I would get Y=0 if I input for X and NO SOLUTION FOUND when I try to solve for X. There is not a lot of documentation on these functions. In fact the package came with the Edition 1 Manual, which does not mention them at all. BTW, I did manage to reset my old one and it is still alive (thankfully). I'll have to find another case for it. ▼ Eddie Shore Senior Member Posts: 260 Threads: 40 Joined: Jan 1970 04-10-2005, 12:47 AM I ended up returning the new 17BII+ (not much keyboard difference and the Let and Get were not working the way it was supposed to anyway) and got a 12C (Platinum) instead. What the heck, I have not a version of the 12C or an HP voyage to begin with. I am keeping my old (2003) 17BII+ because I can live the keyboard and live without any reincarnation of Let and Get. Going through the first few chapters of the 12C(Platinum), I can see why everyone gushes about the HP 12C series (I was wrong thinking it was overrated). ;)
