cannot power "on" ASUS laptop after power outage

On Thu, 15 Oct 2015 11:33:13 -0700, "Adam" Gave us: System: ASUS N61JQ (laptop) Host OS: Ubuntu 12.04 LTS After a power outage yesterday, pressing the power button of ASUS laptop does nothing. The laptop was/is connected to an APC battery backup (surge protection only) outlet (via AC adapter). AC adapter's green light is "on". Any ideas? I did a simple google search... https://www.google.com/?gws_rd=ssl#q...er+requirement It yielded listings for where to get replacement 90W adapters, but scrolling down the page shows a lot of chatroom queries surrounding problems with this particular laptop and its batteries and power supply. It also lists the circumstances under which the failure modes are occurring. It would appear that the battery "watchdog" circuitry Asus incorporated into at least this model of their laptop line has some problems. A slight dip in the output of the power adapter or even too much ripple voltage presented by it when loaded may be what is going on. The new ones seemed to only be $12 to $15. It might cause less hair loss to simply get a new one. It is always nice to have backup power supplies in the "dongle" or "wallwart" realm anyway, since most are ultrasonically sealed and unserviceable. Thanks (NumeroUno), you're right. A new AC adapter did the trick. Nothing else seems to be wrong with my laptop. But, the reviews for the Antec NP90 that I bought is not that great and was not cheap ($40+). But, it has AQ3 (3-year parts & labor) warranty. Any Universal 90W Notebook Power Adapter 19V recommendations? Also, how can I prevent this from happening again? The problem is with the power circuitry internal to the ASUS laptop, right? Take a look; https://www.amazon.com/s/ref=nb_sb_n...JQ++ac+adaptor http://tinyurl.com/nkdjajy -- Caver1 Thanks, I was looking at... Targus 90 Watt AC Laptop Charger http://www.amazon.com/dp/B0054JE64I/...=ISTHDUL7IAZ9E But, I like the PWR+ more. |

The problem was the power outage killed the ASUS AC adapter somehow. The laptop works fine with a new/trial AC adapter. -- Mike Easter |

On Fri, 16 Oct 2015 20:13:29 -0700, "Adam" Gave us: Any Universal 90W Notebook Power Adapter 19V recommendations? The Lenovo 90 Watt unit is nice, but you would have to put the right output plug onto it. I'm surprise that they don't have that ac adapter plug connector better standardized. They are standardized, but the maker gets to choose the one they want to use, and the plugs/jacks are not tied to a specific voltage to be fed, though there was a push toward that end in the beginning of the standard. They are in metric and Lenovo uses the biggest I've seen, and likely the right one for 19 Volts, but the other 19 V laptop makers might argue against that statement since most of them adopted a slightly smaller choice. So, there is a standard for the plug sizes and center pin diameters, but they are not tied to or standardized against a table of voltages. There are 5 and 12 volt "typical" choices, but they too are not set in stone. AND 19 Volts is a non-standard (as it were) DC supply source, so there is no plug size designated for it at all. https://en.wikipedia.org/wiki/EIAJ_connector Thanks, maybe I'm missing something but if desktops can be so nicely standardized, I don't see why laptop PSUs can't be standardized in a similar manner. |

Thanks, yes, I'm super glad that the laptop is fine. Now, I'm looking for a "quality" AC adapter with all features (L-shaped plug/jack, 3-prong wall jack, LED indicator, long warranty, etc.) that I prefer. I don't mind the cost so much as the features. It's worth the investment. -- Mike Easter |

Just where is it you think ASUS gets their supplies made? Probably China, but ASUS should have some control over the design and manufacture. Knock-offs bought directly from China may not have been adiquately designed for the application, and most likely haven't got the electrical safety certifications required in the destination country. -- __ __ #_ |\| | _# |

Probably because there's little commercial incentive, and as the laptop power connector is going to be exposed to your average "idiot user" even a voltage to plug standard wouldn't prevent someone having trouble because they try to use their 12V 4.5A laptop with the 12V 4A power supply from their old one. There'd have to be a long list of probably tens of power connectors designed for the different current ratings and voltages, or an electronic system for identifying the right power supply (I think some laptops might do this, but there's no industry standard). -- __ __ #_ |\| | _# |
