    Power went off while under high load.

     

    I might have heard a snap noise coming from the laptop, but I cannot be sure, maybe it came from the speaker.

     

    When reconnecting the power supply, charging LEDs come on on the laptop, as if charging the battery.

     

    When trying to start the laptop, then either the LED light briefly turns green for 1/10th of a second, then nothing happens, or the blue LED blinks. In both cases t the power supply goes offline, i.e. the LED on the power supply goes off and won't come back on until de-plugged and re-plugged in a socket. This suggests an electrical problem within the laptop, maybe a short. The power supply also turned itself off when I accidently shorted it.

     

    When holding down the power button of the laptop, a very faint clicking noise came from the power supply.

     

    I also noticed USB ports were at least partially powered.

     

    I checked the power supply with a multimeter and it delivers 19V.

     

    There was not the slightest burn smell coming from the laptop.

     

     

    => so it might be a number of things.
    1) the power suppply looks ok, but maybe it's shot somehow and despite testing ok for voltage is unable to deliver the required amperage of 11. something. but it's unlikely.

    2) the long defunct battery interferes with the laptop's operation. shouldn't be the case as it should be able to operate without, but who knows.

    3) the power jack/internal connection is faulty. unlikely because I almost never plug it in or out, the power jack doesn't move.

    4) a protective fuse fried just behind the power jack: this might have happened. I was too agitated to think about a fuse. If that's the cause, it will be an expensive fuse. this scenario is compatible with the total absence of burn smell, but then I wonder why trying to turn on the laptop turns off the power supply.

    5) something more nasty past the power jack assembly: I have no idea. I know there are one or two chips on the motherboard responsible for brokering the power to the mainboard's components, like the CPU, card slots, USB ports, etc. maybe it's one of those chips that failed. that's compatible with all symptoms.

     

     

    Back in the day I used to do some component-level work on circuit boards. It sounds to me like you have a short (although usually what happens with laptops is that the adapter will shut off the moment you connect the adapter plug to the laptop DC jack). Trying to figure out which of the thousands upon thousands of IC's on the motherboard is causing the short can be extremely difficult. A shorting chip almost anywhere on the board, whether or not it has anything to do with a power circuit, can cause the whole board to test shorted with a continuity meter. We used to hookup a benchtop power supply (which could not be turned off by the motherboard over-current protection) to the motherboard and literally see which chip got sizzling hot (a good sign, but not foolproof as to which chip was causing the short). 

     

    Any repair shop should have a universal power supply to test the adapter in a jiffy. Unlikely, from your description, to be the problem. 

     

    You can rule out the blown fuse. There usually is no such fuse to begin with (that would make too much engineering sense), and a blown fuse would create an open circuit, not a short (and so would not cause the adapter to shut off). 

     

    A bad DC jack can certainly cause a no-power problem but wouldn't cause the adapter to turn off. I think you can safely rule out the DC jack. A bad power jack would likely cause an open circuit. 

     

    There are laptops now with internal batteries (non-cartridge) that simply will not power on even with the adapter if the battery has gone bad in certain ways. A possibility. But why then would the adapter turn off? Again, sounds like a short. 

     

    Sophisticated board-level repair shops sometimes use expensive FLIR cameras to identify the shorting chip. Otherwise you "current blast" the short with an external power supply and keep ramping up the amps until something starts to smoke. Sometimes you get lucky and it's a redundant capacitor which fries under the load and, voila, working laptop. Not exactly scientific but sometimes it's your best bet to resurrect a dead board when all else fails. 

     

    Whether a failed chip results in an acrid odor depends on how bad the chip has fried. It's almost better when it does fry badly, makes it easier to identify on the board. No stink and most likely everything will look fine visually to the technician. 

     

    There are hundreds, if not thousands of chips on the motherboard (not just two or three) responsible for the various power circuits on a laptop motherboard (if you're going to include the small armies of multi-layer capacitors and resistors involved in such circuits). 2/3rd of the entire motherboard deals with dishing out power. Could be any of these that went bad. 

     

    I can't comment on the technical prowess or Thai computer technicians but if some component on the motherboard is shorting it's most likely a mosfet or some "footless" IC and I doubt a Pattaya tech is going to have the knowhow, schematics, pricy rework equipment, optics, or part sources, to do the job. Although maybe I'm wrong and Thai PC techs are as resourceful here as the scooter techs. Anyway, good luck.

    Politics only matter to me when I’m bored or with insomnia (such as right now), as a pass time. During other times I prefer to invest my time, into what really matters: $ ¥ € £ 

     

    But if you think you’re gonna change what’s wrong with the world with your debates in TVF, well, whatever floats your boat. I’d still be more than happy to come here and debate whenever I’m bored.

    95% of you are Brits and Euros who pretend to be experts on American politics. The other 5% are cowardly Americans who won't stand up for their country. Any any rate, it's hardy worth anyone's time and effort to make a post on this sad anti-western forum.

    Don’t fight guys. We could all agree arguing politics among us is pointless and won’t lead anywhere, and neither will it fix the current world issues ????

    You're part of the problem. It doesn't matter how insane, unhinged, irrational the Left becomes, there will always be the complacent normies like you to pretend they don't exist?

    This explanation makes no economic sense at all. China is a middle income country. It's economy is proportionate to its population. So while it has more people, it also has to have proportionately more jobs available. What's more, it's economy is growing quickly. If anything, demand for workers should be stronger than in other middle income nations where the economy is growing less quickly.

     

    Anyway, clearly the system all about control. What do jobs have to do with denying people access to trains because they lack enough social credit points?

    It's just staggering and pathetic the sort of mental acrobatics you're willing to indulge in to defend the CCP while at the same time defame your own countries. It's beyond sad.

    TVF has been promoting anti-westernism for years now. I may be banned for this comment, but it's absolutely true.

    I trust you understand at least on some level that the politics of the USA often has a roll on effect on it "allies" many of which were alienated during the previous administration

    The anti Trump feeling are not necessarily anti "west"

    The comments have nothing to do with "guilt" perhaps they hold other more ethical standards than the previous president exhibited, and have a greater understanding of governance than displayed by the previous president, and saw things which they have a right (freedom of speech), to express

    Civilised people can agree to disagree, with attempting to close down open debate. That is why forums exist.

    A little like "Letters to Editors" once did.

    A British guy in Thailand once said to me, "When America sneezes Britain catches a cold." But it's weird and unhealthy how much interest non-Americans take in American politics, and the arrogance is abominable. I stand by my previous statement, that all you Brits and Euros need to worry about your own countries for once and stop sitting on your arm-chairs expatiating on all that's gone awry in Yankee-land.

     

    And you're wrong--it has everything to do with western, male, white guilt. Let's be honest here. Why uproot your existence and move to a third-world country, and in the meanwhile, consort with the native women? Just because you prefer their stimulating conversation?

    Great stuff .. if it's a Bible he has to swear on can we expect a bolt of lightning straight through the ceiling from the Lord above vapourising him with nothing left but smouldering shoe soles .. 

    We can only if that bolt goes through Biden and Pelosi first. Maybe then it might hit the Orange Man by happy accident.

  7. Ah, yet another anti-Trump, anti-western TVF post. It really does beg the question as to why you aging white western men decided to abandon your mother countries for SEA if you actually agreed with the politics of said mother country. If everything is so wonderful in Britain and the EU, why not make that your homestead?

     

    Talk politics all you want, but this is all just white male guilt consciousness by any other name. And it's getting really, really old.

     

    I'd hazard to guess that 90% of TVF commentators on American politics aren't even Americans. Get a life. Worry about your own country for once. It's sad. There are some good Thai soaps out there.

    That is certainly NOT my understanding of progressive either politically, psychologically or socially

     

    Not mine either. Unfortunately that is how the current Democratic party understands it, which is why I "walked away" from the Democratic party after Bill Clinton encouraged and countenanced the whole miserable PC culture in its adolescence  (Yes, I used to be a Democrat!)--a PC culture now in the full bloom of its monstrosity under the current Democratic leadership.

    I am wondering what is so wrong with "progressive" thinkers in any branch of justice or administration?

    Without progressive thinkers, we would be using horse and cart for transport, and writing with quills on parchment, and still have slavery

    Nothing would necessarily be wrong with progressive thinkers so long as they actually were progressive. Nowadays what passes for "progressive" thought is the regressive philosophies of Marxism, racial and gender identitarianism, and post-modernism, intellectual relics all. These are decades-old cliches. That being said, the Republican party has become a largely nostalgic party predicated on 1980's Reaganism--an utterly doomed party unless the more populist elements take over (which is what the left wing really should worry about). Same for the Dems. The longer they follow their doomed course of rehashing failed Marxist ideologies and 1960's militant identity politics, the more new right wingers they're going to spawn.

  10. RBG deserves respect but who cares what her dying wish was? She was hardly apolitical. She had her own political agenda to push. Of course she wouldn't want a new judge appointed now because that judge is guaranteed to be a conservative. What a shocking deathbed confession that must have been!

     

    If a conservative judge died under similar circumstances, the left wing would be stampeding over kittens and babies right now to cram their progressive judge onto the bench. It's almost endearing to believe there are souls so simple--so Candide-like--on this forum as elsewhere that they actually believe the Democrats would do anything else. This is, after all, the "by any means necessary" left wing. And there has been literally nothing so far the Democrats haven't stooped to in order to further their own progressive agenda. And nothing they won't stoop to in the coming months. They've already threatened as much.

     

    The nice thing is I am finally starting to hear the word "hypocrisy" from the mouths of left wingers. I honestly had thought that word no longer held any meaning for them, given that in the world of social justice everything is about 'power dynamics' and concepts like truth, logic, science, and rationality be damned. I'd thought a classical concept like hypocrisy was an element of "whiteness." Now they suddenly care about intellectual integrity, consistency of statement and thought. Just in time, and how convenient.

     

    The senate needs to push this judge through as if they were linemen for the Chicago Bears. The right wing needs to be willing to employ the same cynical and ruthless political tactics that the left has been indulging in  (so, so sanctimoniously, by the way) nonstop for years now. I don't care about their threats, nor should anyone else. If Trump gets elected they will pull every dirty trick imaginable anyway. Nothing to lose. A judge to gain with lifetime tenure.

    trump getting the facts straight. trump has power and is constantly attacking the Constitutional rights of US citizens e.g. voter disentrancement and freedom of speech (people disagreeing with trump are called out as scum and traitors).

    I love these broad and hyperbolic generalizations about how Trump is this or that and yet the poster never feels compelled to offer a single concrete example in terms of policy supporting the claim. It's all just empty rhetoric.

    This is for the benefit of Cryingdick, Ozin Pattaya, EvenKeel and the one that loves Thai Beaches.

    This subject demonstrates quite succinctly the different approaches from opposing arguments. The frustration when hearing your thoughts (and they are valid sometimes) is your tendancy to have such black and white (pun intended) views on what are quite nuanced subjects. You argue that 'cities are burning' and 'dems can't maintain law and order' by assuming we are advocating the violence and destruction going on by a minority of protestors. This is just simply not the case as no one is condoning the hooligan element obviously present at these demonstrations but what we are saying is a measured approach is required (one that the 6 mayors are advocating) that doesn't incite even more trouble. This is what the facts are saying; yes there is vandalism and trouble (although not nearly as much as you are trying to make out) but the protests where subsiding and petering out (as often these things do) until Trump added fuel to the fire by ordering a heavy handed federal incursion that does nothing to help the situation other than get his own base fired up yet again and distract the populace from his terrible handing of the C19 pandemic.

    The 6 mayors are people who know what is best for their cities and they are all saying they don't want federal help because their approach is de-escalating the problem rather that Trumps approach which is not. This is now bearing fruit with Portland courthouse area seeing its smallest crowd in four days and more importantly, those present remained peaceful through the course of the night with no violent agitators apparent therein.  https://www.dhs.gov/news/2020/08/03/portland-riots-read-out-august-3 . This of course can be put down to the use of Federal forces but is likely just to be the petering out of these protests.

    And correct me if I'm wrong (I've scowered several news sites for verification) but apart from Portland, I cannot see any other troubles in any other US city (I'm not 100% on this so would happily be corrected if not true).

    Big problems require nuanced solutions so when you are cherry picking scenarios to back up your narrative, please remember there is more than one way to skin a cat, something that many of us understand but many of you don't.

     

     

    This is a very well considered post. The problem is that the lack of appreciation for nuance is coming almost exclusively from the Left. These, make no mistake, are the "black and white" thinkers. So if you want to decry the lack of nuance, maybe the political party you most likely sympathize with shouldn't support the likes of Antifa and the BLM. My personal beef is with left-wing radicalism, which has been adopted by the Democratic Party, precisely this lack of nuance of which you speak. Don't pretend for one moment that this is coming from the right wing. This bigoted, intolerant, tribalistic mentality. That's on you Lefties.

    China is laughing much more about Trump (Ok, they will soon laugh about UK. Nothing personal about UK, it will just be too small to have any significant weight). He's only posturing for his electorate and did not achieve anything re China.

     

    A rational leader would have sought to find some common position on China, instead of starting a tariff war with the EU and insulting European leaders. A rational leader would also have not aborted the TPP and would have proposed an alternative to the Belt and Road initiative.

     

    On top of it, Trump has no credibility in Europe, except maybe for the current Polish and Hungarian proto-dictators. Any sensible government following Trump? Are you kidding?

    Common ground with the CCP. Good luck with that. That does seem to be the strategy of Britain and Europe: To cherish a false and utterly deluded hope of "compromising" with the CCP while secretly, and in most cowardly fashion, depending on the might of America to rescue the Western world as Britain and Europe do absolutely nothing in the meantime, besides cower behind their "woke" and globalist sentimentality.

     

    Countries like Poland REMEMBER what it was like to live under a communist, far-left regime, so it should come as no surprise that they are reluctant to embrace all this sanguine multiculturalist rigmarole. No surprise that they should cherish their independence and their sovereignty. If that makes them "proto-dictatorships"--a typical example of leftist hyperbole--then more power to 'em!
