e-studio 232 no power

[tmaged]

On of my techs goes on a call today for a dead ES232. He checks the voltage at the surge, it's good. Unplugged the network cable & the machine powered on. They said it had shut off 4 times this AM. My tech left the network cable unplugged & they said it was fine all afternoon. If we plug network back in tomorrow & it looses power, I'm planning on putting a switch in between. Any ideas or anyone seen anything like this. I don't think it's a POE connection but could that cause it?
Thanks for any suggestions.

Toshiba machines are quite sensitive to power problems. So reformat the HDD and re-flash the firmwares. Check grounding of machine.
