MarkK,
How does one disassemble the ZAGGMATE? I've had mine for two years and it has been flawless . . . Until now. Somehow, either there is crud under the on/off switch or a possible break in the solder at the switch, but I' m having trouble switching it on. At first it was intermittent. Now, well, as you said, it is all but dead. Since it's well out of warranty, I might just disassemble it a try to repair it. I have come to rely upon it and, since it is discontinued and I still limping along with an iPad 1st gen, I can't just replace it.
Standing by,
