[NTLK] [Help] Need Assistance With Repairing eMate 300

[Forrest]

Hi Justin,

Newtons and eMates are very sensitive about the DC input. For years we have been warned not to use anything than the Apple supplied power adapter.

As for whether or not you fried the eMate, I would accept the advice of others here that have much more information on that issue than me.

Mahalo,
Forrest
