My zaurus C3K has a very bad autonomy, something like an hour... In fact when I received it, the Z didn't want to turn on, so I've changed my power supply polarity.
The problem is that I've heard that the Zaurus doesn't have polarity protection.
On my battery it's written "3.7V" and my adapter was set on 4.5V until now.
My actual polarity is -o)+.
Is it bad ?
