The button is working as before. The relay is clicking is as before. Just the main power and fans are not starting after the relay clicking. |

--- Quote ---The mixture of not not booting up at all but still keeping time&date doesn't sound like a C-MOS battery issue to me. --- End quote --- Did you measure the battery voltage? Anything below 3V, even 2.95, is suspicious. |

I would still put my money on a bad capacitor in the PSU. The problem is you probably need to disassemble the whole thing to reach the PSU. Personally, in your situation, I would simply declare it broken and let the company do what they do with broken stuff. Unfortunate if it get destroyed :-\ |

A bad mobo cap will send the PSU into instant shutdown or there's a bad cap in the PSU. |

I kinda hoped that someone here would have observed the exact same behavior, repaired it successfully and could give feedback how much effort it was. --- Quote from: Kosmic on April 20, 2024, 03:57:44 pm ---Personally, in your situation, I would simply declare it broken and let the company do what they do with broken stuff.

But I definitely wouldn't get a new scope or even a comparable one at my bench. Actually, it's rather clear that sooner or later I won't have my own bench anymore next to my desk but need to share it with colleagues who come to the office only once a week or so. Sad times for engineering. |
