cannot power "on" ASUS laptop after power outage

I never said a damned thing about using a supply that has been falsely labeled as an OEM replacement. I know you didn't. I was the one talking about non OEM products and you replied under some strange assumption that I was talking about all power supplies that are made in China. I wasn't. -- __ __ #_ |\| | _# |

No. The chinese ps makers have their own engineers and are the best at it after decades of doing it (literally), and ASUS picks one from their lines and has several M of them made, and they only thing they get that is custom is the labeling and a guarantee that they will not kill (read stop producing) the model. Then that's the control ASUS have over the design and manufacture of their power supplies. Cheap ones from Ebay do not have the assurance of that approval by the laptop manufacturer. Knock-offs bought directly from China may not have been adiquately designed for the application, Nobody said anything about buying a false branded "knock-off". There are literally hundreds of ps makers who make good products and they do not need a brand sticker to guarantee tagged performance. That is what CE and TUV and UL certs are for. And YES, they ARE valid cert declarations. Sheesh. Some of the laptop power supplies on Ebay are fake OEM products, I should have said "third party" instead of knock-off, but I meant ones that are not OEM branded. Either way, there is little assurance that the design is sound and truely approved. There are plenty of poor charger designs, some with fake certifications, shown in teardowns on the web. No need for any tear down. Place the output on a scope and put the supply under its full rated load and look at the ripple. It really is that simple. Come back an hour later and check the case temperature and ripple again. Easy greasy chin-o-****in-nesey. That covers safety for equipment before the components age. It doesn't reveal safety for people with regards to things like circuit board track spacing that are covered by safety certifications. The average consumer also has to brave the electronic frontier without the aid of an Oscilloscope or variable load. -- __ __ #_ |\| | _# |

It is surge sensing. If your PC is up with its 1000W supply only using 250W of it, and you try to add a hard drive while it is live, you can cause the entire supply to shut down, even though the HD and all of its inrush only taxed the rail a few more watts. It can also happen merely adding a CD or DVD reader as well. It is the change it senses, even if well below its max capacity. Hot swap supplies do not do this function. ATX supplies do. That is why they are so hard to use as a bench supply. but if a laptop is on the edge of the maximum current from a PSU, then it could shut down intermittently or have other problems, the cause of which may not be clear to the user. Hardly a difference one would experience in your example of a mere 0.5 amp differential. Now try to move the goal posts again. You're clearly after an argument. I'm just suggesting the way that a standard for laptop power connectors could be implemented, bringing up largely irrelevant points isn't going to get anywhere whether they're right or not. Defecant_Linux_Luser_Numero_Uno is a very angry person with some serious mental issues. He needs to make an appointment with a good shrink. It seems to be common in the Linux community for some odd reason. Anyway, here is a tear down of a cheap iPad adapter vs the real thing. It has nothing to do with being made in China and everything to do with being made to manufacturer's specifications vs something that is made as cheaply as possible and barely works. http://www.righto.com/2014/05/a-look...rs-pricey.html |
