content: 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 got plugged in not charging error,long story short,a wire had come unsoldered,i resoldered it and belled the wires thru to the charger pcb,all were good but i asuume the loose wire shorted and fried the data id chip as still wont charge,i have a spare psu,i took them both apart,the only thing going to the data wire is a to92 device,its marked with two rows of numbers,top row reads 2929,second row underneath the first reads c4381it 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 chineese ebay supposed 60/40 pb solder thats more like dogshit when melted!

content: Quote from: m3vuv on March 02, 2022, 08:42:25 pmFWIW, tooki, Brumby, and others around here have been trying to help. Why bite the hands that feed you? I think in another one of your threads tooki even made an effort to share with you some very useful info in this link:http://www.catb.org/~esr/faqs/smart-questions.htmlAnyone who uses Internet forums could probably gain some good ideas from the link.Maybe just look over tooki's link at high speed. If you see some shoe in there that fits, wear it, and if not, don't wear it - but why keep going in the punch bowl you are trying to drink from? At the very least take the time to write with enough clarity that makes it a tad easier for people to understand your questions/requests/demands. Try initial caps, some full sentences, spaces between words, maybe a proofread here or there, stuff like that. Take it a step at time. It doesn't have to be perfect. Just make it look like you care about other people's time and effort as much as yours.If you ask a lot of questions you are going to get some advice, maybe even regarding topics for which you didn't think you needed advice. Look as it as offers of assistance, or not. But mostly chill a degree or two. It's supposed to be fun here.

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 05, 2022, 06:17:06 amSo what does my nationality have to do with it? Careful on your answer here, you're a hair's breadth from a permanent ban.You didn't post in some weird alien script, rather you posted like you're a young child that never managed to grasp the basic usage of the space, or paragraph breaks, or punctuation and when offered help or guidance decides to act like a child and throw a tantrum.We get people of all nationalities here and they all have varied levels of abilities in their English skills, and as such they are humble enough to try their best to word things in a way that can be understood when asked. You repeatedly insult people because you're extremely hard to understand and are unwilling to put the effort in to do better.Let me re-write your post in a way that is readable as an example you can learn from. I have also corrected the plethora of spelling errors which if you're using a modern browser like Chrome/Brave/Edge (and I believe FireFox) will even highlight for you and offer spelling corrections before you even submit your post:QuoteAs for "Answering the question"... how? we have no schematics, no circuit diagrams, and no idea how the charging circuit works. You're asking us to speculate based on practically zero information. Honestly you're better off following the advice given which is to simply source a universal charger with support for your laptop as you have clearly done irreparable damage to your PSU if you did indeed short out/damage the IC that negotiates with the laptop.

content: I used to work the beat in a previous life monstering ppl with the argument that the Enter key is one of the biggest keys on the standard keyboard, yet under utilized. That was fine until one day a particular angry ant pointed out that the (new fangled) smart phone keyboard is different.The beauty of this forum's tools is the preview feature. If you can resist the urge to post when ur hot, the preview remembers the points you were trying to make and gives you the opportunity to sleep on what you are trying to say.
