kudos:1 | [motherboard] Laptop COMPLETE power failure .... fixed by lettin TL;DR - Laptop was full power failure, not even the AC port status LED would light up. After it was left disconnected for an hour, it worked again. Why?
LONGER VERSION
This follows what I said above...
I tested the AC adapter with the multimeter, it read the 18.5V (As it was rated).
I removed the battery, pressed power for 15 seconds, whatever, nothing worked.
So I blamed hardware failure, internal PSU of the laptop fudged up. What else could it be?
So without delay, I jumped on HP's tech support chat to jump through their hoops as quickly as possible to get to the RMA.
Since chatting is more slow paced, I started put back the battery, and retried (Because whatever).
Behold, it worked!
WTF?! When I interrupted the tech support, telling them it suddenly worked, they said that it happens often due to static build up....What?
This feels humiliating. I was building my own computers since 1997. My first laptop was a bare-bone build-it-yourself as well!
I gotta understand what happened here. |

kudos:2 | Re: [motherboard] Laptop COMPLETE power failure .... fixed by le No way to know for sure what happened. HP should have said the same thing, they have no way to know what happened precisely.
I would call it a fluke and go on about my day.
If I had to give a theory, I would say there was a bad connection between the battery & the connectors. Motherboard got a signal that there was an anomaly and refused to power on - more or less a short in the system.
It's about as plausible as 'static electricity buildup' but is something I have actually seen and makes more sense in this case. Typically static electricity cases go down a quick one-way road and it's not one to recovery. |

Well if it's the case, that laptop still has a good 10 months of warranty left. Plenty of time for it to fail completely and have it replaced. |

kudos:2 | Impossible to say with any certainty. May not have even been a "failure". Keep an eye on it in any case. |
