content: Since you haven't posted the story here, I looked up the original thread.You have to understand:1. Communications is a two-way street2. People contribute here voluntarily and for freeSo - if you want help, you need to make the effort to present your question in a way that iseasily readable- so that the people who have the knowledge can understand it straight away. If it requires interpretation or re-writing so that the message is clear, then you can expect a lot of people to avoid getting involved.Getting upset at being criticised is just silly. It says to us that you aren't prepared to make a decent effort and expect magic answers.We are a pretty easy going group here, but this sort of attitude is not going to get you far.

content: O.P's lack of GoogleFu and poor attitude continues to entertain. It took me about five minutes to narrow the mystery part down to a small family of similar parts from a well known manufacturer we love to hate*, and a couple more minutes to find a method of spoofing one on a popular electronics website (and not buried in a forum post), and a manufacturer's page that states "***** are only available preprogrammed with customer-specific and write protected data" and "***** devices are only available to existing customers. New data patterns are no longer accepted". (Part name and description obfuscated because we are trying to teach O.P. how to fish . . .)S.E.D catchphrase: "Friends don't let friends use <specific_manufacturer>!"

content: Here is what you originally wrote, with some simple changes THAT MAKES IT 10 times more readable:Hi all,A few weeks ago my Dell Inspiron charger DC lead broke where it joins the plug. I carved off the plastic and soldered the wires back onto the DC plug body. It worked fine for a few days then I got a "plugged in not charging" error. Long story short, a wire had come unsoldered. I resoldered it and belled the wires through to the charger PCB. All was good but I assume the loose wire shorted and fried the data Id chip as it still wont charge.I have a spare PSU. I took them both apart and the only thing going to the data wire is a TO92 device. It is marked with two rows of numbers: top row reads 2929, second row underneath the first reads C4381. It tests as a diode in my component tester. Is this what sends the charger Id to the lappy?TIA.P.S. I think the joint fail was due to Chinese eBay supposed 60/40 Pb solder thats more like dogshit when melted!Make an effort in your communication and we will respond more positively, but if you want us to understand your slack scribble and get so offended by us having to re-interpret it, then I repeat my previous suggestion.

This is not our fault, it's yours, plain and simple. You need to humble yourself and accept that you need some help with your grammar/wording and accept it when offered or you're going to end up banned from this forum also.

content: Quote from: m3vuv on March 11, 2022, 10:42:59 pm1) How can people know what you're already aware of?2) If you're so concerned about wasted bandwidth then perhaps the internet is not for you3) Nobody here is obligated to answer your question at all, this is a public open and free community governed by a set of rules to try to keep things somewhat organised and amicable.4) Calling people "twats" and various other derogatory things is indeed you meaning to be rude, don't try to play this down.5) You need to learn the difference between someone picking on grammar (ie "grammar police") and someone pointing out that your writing is almost completely garble. If they were complaining that you made a single miss-spelling, or used `your` vs `you're`, etc... then yeah, they are a grammar natzi, but in your case, your posts are so poorly written they don't even approach any level of correctness making them extremely hard to read for all of us.In short, the problem here isn't us... it's you. Settle down, stop being so angry, learn and grow instead of continually acting like a child.

content: Quote from: m3vuv on March 12, 2022, 06:30:39 amYou need to ask your questions in a way that the question is clear, and doesn’t take effort to figure out. We are not paid tech support, so you have no “right” to expect us to wade through incomplete questions written in a way that makes them incomprehensible. We do not owe you a response. If anything, it’s the people doing the responding who have a stronger claim to being able to dictate the terms on which they provide you, free of cost, a response.Thus: If it’s too hard to even figure out what the questionis, most people will just ignore it altogether. You had the fortune (and I say that in earnest, it’s not sarcasm) that someone told you that it’s the wording that made them ignore the question. (Fortune because now you KNOW the problem and can take steps to address it.)But when you come back with an entitled, snippy tone, you turn everyone against you. The initial poor wording could have been dismissed as ignorance, but your responses ooze entitlement, and that will ensure nobody answers.I shared this link with you before:http://www.catb.org/~esr/faqs/smart-questions.htmlSeriously, dude: READ IT and take it to heart. Once you follow it, you’ll find that your questions are infinitely more likely to get answered.

content: I used to be the technical editor for a well known computer magazine here in the UK. I've said this here before, but it bears retelling. There's an old saw that nutters write to the papers and magazinesALL IN CAPITALS AND IN GREEN INK.. I can say, having been the man to open the post more than once to find a letter just like that, that itreallyhappens. Not only that, but I've observed the phenomenon at more than one magazine that gets letters from the public.Not all crazy "letters to the editor" are that obvious, but there's a loose rule that the more idiosyncratic the presentation, the higher the probability that the writer has some *ahem* alternative approach to reality. So alternative CAPITALISATIONS, alternative 'uses' of ??, punctuationmarks, random font changes or bolding andheavy emphasis of half the clauses in every sentenceare all signs that should be heeded. Also warning signs to heed are: rando speeling (sic), inappropriate usage of argot of the kind that you'd expect from someone who when speaking ends every sentence with "innit, fam", as should dropping of initial capitals and final full stops, the absence of paragraphs, or every sentence being a paragraph to itself, or no real fully formed sentences at all. See more than one symptom in a letter and it goes in the "funny letters" file rather than getting published or answered; 'funny' here being'funny peculiar', not'funny ha-ha'.Sometimes the letters are funny ha-ha as well, but more often they're either sad, slightly scary or, thankfully rarely, need to be immediately passed to the police. I've seen a couple of the latter too.Oh, and you know that footnote on the letters page that says something like "Letters may be edited for length or clarity"? Ninety percent of those worth publishing need editing for either clarity, spelling or basic grammar.So, that's about 9% less that need editing when compared with what the actual paid writers turn in.

What do you think you are going to get out of being demanding and rude of people you're asking to help you for free? You're going onto my ignore list because of your attitude. Sorry, I can't be bothered to help people who act entitled and nasty. Perhaps you're just socially inept and completely unaware that you come off as incredibly rude but that is on you to figure out before you make an ass of yourself in a public forum.
