My crazy HP 15c repair

[Johnboy]

Just a comment on heat stakes... I haven't tackled any voyager ones yet, but I have taken on the heat stakes in the 41c series with pretty good success. I would bet the approach to both would be pretty similar. I find that when you want to separate keyboards that are heat staked to the front of the calculator that you should to leave as much of the heat stake intact as possible. To do that I find that lifting the head of the heat stake gently all round is better than just slicing off the top, so it comes of more donut shaped. This leaves more heat stake to work with when reassembling. I mostly do not use the donuts for reassembly, but use a small blob of hot glue instead. If you want to try and reattach the donuts, it worth noting that HP tends to use ABS plastic for it's calculators, so you can easily use a liquid cement to "weld" the donuts back on to the heat stakes. That's probably going to be better than applying heat to reattach them. The other advantage of using hot glue is that you can gently heat it if you ever need to take the keyboard apart again.

HTH
