A few months ago I installed a Sonnet upgrade processor (1.2GHz to my Cube 500MHz; 1.5GB RAM, Panther) and it went well. A week or so ago (and I posted about this) I could not power up the Cube with either of two monitors (one ADC the other VGA). Both monitors worked with another "virgin" Cube. I found that replacing the battery (November 19 th) restored the Cube. And it worked well until last night. It won't power up again. Anyone have a similar experience or advice? I have a call into Sonnet but I am not hopeful.
