Title: Keyboard Problem On Ac
Post by: Sna on March 04, 2005, 03:05:54 am

Hi
I've a little problem with my C760 running PdaXRom
When i'm on battery, no problem, the Zaurus responds flawlessly
but when i plug the AC cord, my keyboad seems to be mad, when i press a key once, it write 3 characters. when i keep a key pressed, the repeat stop after a little time. And some times, it event write characters without pressing any key

I first think that was a pdaxrom problem, but yesterday i flash my rom, and in the OK menu, the problem is the same, it seems then it is a hardware problem, but i don't have any idea how to avoid this :/

Anybody have the same problem?

might be a bad power supply, putting lots of noise on the power rails which is causing it to mis-read the keyboard?

does it happen with a sync/charger cable?

thanks for letting us know.

it seems that Sharp need to learn a lesson or two from Sony about power management. Z's are way too easy to blow up with bad power, so you were lucky!
