Customer blew up his laptop with a universal charger - Hp 13-d061sa not charging not coming on

[@Markus-fw4px]

Don't you dare making your videos short! The fun begins with an hour or more. Love it.

[@computersrepaircotesaint-l7407]

yeh we love him, he like father

[@raffaelecotis3960]

hi, i'm an italian man. I have been following almost all your clips on youtube for years and I am also subscribed to your patreon channel. thanks to you i managed to fix several notebooks in the past. thanks for sharing your knowledge. If I were to come to England tomorrow I would love to stop by your shop to say hello. Thank you

[@electronicsrepairschool]

Thank you very much!

[@mnemonicrulez]

You always get a like with your videos Sorin but when you say "proper calibrated fuse" there should be a double like button to press!

[@mm0077]

Another good learning video. I think short videos would be boring coming from you as I am so used with all the advice, allegedly dodgy repair, hotglue drama with hinges in the mix, rosin and inquisitive analysis of the fault and so on. Many from the comments below here love it. I just look forward in seeing any short or long videos LOL.

[@repairstudio4940]

Great one man I wish I had some that easy...but had it been super hard psssh this video wouldn't be any longer cause your not only a mentor but one of the best techs on KZbin hands down. Be blessed Sorin. Happy Holidays. 😇🎅

[@siphonkosi4911]

Was able to fix two laptops one was an Acer fuse blown off because of reverse polarity the second one an HP wrong Chinese made charger fried the resistor. Thank you your videos have saved me a pretty penny 😅

[@abdallahharfoush9449]

It has been 4 years Im watching this channel ❤️

[@francisamoah1230]

I have learnt a lot about your videos, and soon I'm starting my repair shop. Thanks Sir.

[@SWARKA1]

A fost prea repede. Bravo Sorin

[@computerworksuk]

Always a pleasure to watch your mind at work.

[@michuuuuu]

This was a burnt section pad, HP splits up the power rail in sections wich are connected by just a solder blob on 2 pads. This might be helpful for diagnosis, if you can just remove sections by removing the solder blob. Recently I had a burnt solder blob on a HP 640 G5 for the cpu supply, looked very similar as this one and I just bridged it. The reason why it burnt was unknown in my case, probably the solder cracked and got hot. Thank you a lot for your teaching and best regards from 🇨🇭

[@martinljubic84]

Above the blown component, "FM1." The writing is not upside down to the blown component. Blown component mostly likely a FUSE.

[@CrucialSpeaks]

Excellent Sorin!

[@meizdronk1782]

Buuuu for me, I thought it was protection diode at the beginning of the video, I think hp usually put a diode with cathode to the plus , but I failed.... Nice video, amazing like all you do, btw your hand made flux is working really fine 😉

[@MrRvdbeek]

We have a smocking laptop. Sorin Is also smoking. Can we fix that to?😂

[@rfr653]

Good job mate 👍

[@tvelektron]

Could have been one of those SMD Inductors (for RF filtering). They also like to burn when a OVP behind them kicked in 😉

[@Steven.Cartwright]

Good video

[@sherifsamy6129]

How can you detect whether its fuse or resitance with oms it may be a resitance

[@adiasterix81]

Foarte misto rezolvarea. Simpla si la obiect. Ca sa fiu realist, eu cautam schema pe net deoarece pe placa nu se mai distingea nimic.

[@alexyo5402]

Salut, stii cumva un shop in RO care fac interventii pe MB? Am un laptop cred ca are un condensator defect (se aprind ledurile si nu i-am facut nimic, a murit deodata) si nu gasesc unde sa il repar. Depanero m-a dat cu flit sa cumpar MB noua.

[@tatkosmolko1672]

carbonised component was by schematics "non properly calibrated resistor". So properly calibrated wire is several times better in all specs :)

[@B9NE]

So on power supplies you use a fuse but on charging circuit you use a resistor?

[@peterdobson3435]

Yes! Most people do not realize that their laptop runs on smoke. Once the smoke comes out, the laptop will no longer run. :)

[@SidneyCritic]

Wasn't that an over current/voltage, ie the charger was a too high voltage, meaning that short circuit protection in the charger is not going to prevent that happening again.

[@ReeseL4D]

If he plugs in the same universal charger again, then the new properly calibrated fuse will protect the board.

[@davidepalombo2141]

Thanks for the video, Sorry about the question but i did not understand how do you fix the damage. After removing the blown component what did you do? You bridge the trace with the solder?

[@guidoneumann9159]

You say external power supply has integrated short protection. What about the power of battery when no power supply connected and board shorts and no fuse exists anymore due to dodgy repair ?

[@tomasmolina8617]

EZ one lol 🤣 I wish I can find it and then been able to fix it. good video.

[@fichambawelby2632]

Sorin, seems to be a diode, or a current sense resistor.

[@natebee3021]

Your amazing

[@terencegraham8414]

Mate, you are a frigging wizard. Cheers eh.

[@HASKINGKENYA]

I learnt slot by watching your videos

[@safn1949]

Well, I saw 2 choices, calibrated wire (that worked) or a new motherboard. Well done.

[@aljosamlinaric8705]

what if burnt component was shunt resistor for current sensing

[@MrRvdbeek]

Shorting the video’s aaah don’t please? You ask what can be the problem eh? And we answer but you can’t hear us. But is funny and we al love to watch.

[@XantheFIN]

I have DIY Magsafe "85W" charger with actually being 250W HP charger with tuned down Voltage level for Apple. Used junk Chinese magsafe connector with own wiring. Been working great for past 2? years. No exploding Apple chargers here like my friend whose Apple genuine Magsafe charger exploded on him once on travel of course.

[@jaimecosta2966]

I have on of thoes laptops. No backlight on the display and sometimes it dosent start up ... Soon I will take it apart

[@bahadoromid3554]

GOOD

[@sarockpashotan]

The burnt component was a protection resistor.i think so!

[@johnathanasiou9284]

Didn't do much "protecting" if it destroyed the PCB track so destructively!

See how neatly NorthridgeFix does repairs.

[@Naz_gul5]

[@flashgordon8554]

NorthridgeFix does neat repairs when he is recording. You don't know how neat his repairs are in general. You don't actually need a neat repair, but a good one.

[@lucianionutcocos4413]

Give Sorin a wire and give Northridge Fx all the tools he needs. Wire will win!

[@gorky_vk]

He also charge what they fix in this show for just repair attempt, real fix are triple what shop Sorin work in charge. Also, he make his video as PR, to get more jobs inside his shop and sell more tools and consumables from his webshop. Which is perfectly fine by me but that make me think about all his videos as commercial, Sorin on other hand just show you how to fix things by yourself. Two different styles, two different people.

[@Naz_gul5]

and Northridge do alot of components changing not deep diagnosis and repair as master sorin

[@Popeyes66]

You ARE good Sorin. Will you show the HP Customer this video ? Will this repair comeback to bite in the future ? That board looked like burnt toast. Good save .

[@waynetaylor2784]

Or you could have put a 0hm resistor (fuse) instead, if power supply did have protection you would not be doing this video, hopefully owner doesn't use wrong power supply in future cos current gonna jump straight through that bridge (properly calibrated fuse) I'd like to see you repair that so quickly, there's dodgy n there's lazy you pick which this was ?

[@incandescentwithrage]

I agree a fuse should have been used, however a 0ohm resistor isn't a fuse either.. don't conflate the two.

[@gorky_vk]

@@incandescentwithrage if I'm not wrong Sorin used solderwire as "fuse". In case of overcurrent it will just meltdown and break just as fuse. Not fast like one but zero ohm resistors also take some time to burnout.

[@waynetaylor2784]

@@incandescentwithrage yes not technically a fuse but often used as a quasi fuse certainly better protection than a random gauge wire., I mean sometimes, it is hard to fuse if faults like over-current/short-circuit occur because of high large fusing currents of PCB traces. Such occurrences might result in more severe accidents. When there is overcurrent, the 0-ohm resistor is fused; thus, it disconnects the circuit preventing significant accidents.

[@johnathanasiou9284]

0Ohm resistor is not a fuse per se, but it does have more resistivity than a wire. Spec sheets I've seen on 0Ohm SMD resistors have a typical max current of 1-2A. As this is a retail repair job & clearly the PCB lands have been burned away, one needs to consider realistic repair costs & a 1-2A fuse wire would be a far cheaper electrical substitute & far more acceptable repair cost for such a low value retail repair item, plus the end customer wouldn't have to wait so long. Had it been a high value item under repair, it might warrant a different approach plus the only one who'll care about a "proper job" is a tech. Whereas this might not wash in a high value item repair shop using high reliability soldering techniques, what Sorin does is repair cheap items

[@incandescentwithrage]

@@waynetaylor2784 I suspect the manufacturer had placed a 0ohm link in the position of the damage on this board. The extremely slow blow characteristic of SMD carbon resistors (with an extreme amount of heat generated) is likely why there was so much damage to the board. Copper wire will not be that much different due to the high melting point (solder will melt first - but that doesn't mean the wire will move out of position and break the circuit). It's down to Sorin to make the decision for the business, but if it were me..I'd have repaired with an SMD fuse (or fuse wire as has been suggested) so the board would remain fixable, should the customer do this again during the warranty period.

[@boardfix9374]

hi. i have samsung laptop (np350v5c).laptop doesn’t turn on when i press power button after i replaced bios battery. can you help me?any idea?

[@snezanailic8944]

It happens also to me , if you don't touch anything else except the bios battery , just plugg the charger in to laptop and pres and hold power button some 10-20 sec , should get lights

[@torsson2]

Check so the power button is connected and if the new bios battery is ok

[@wz4325]

Wow ez one 😲

There are too many resistors in a laptop anyways.

beware of Chinese low quality power supply of any kind. Most of the time they are abnormally too light , and the plastic casing is cheap . they provide improper voltage to your devices , making them to burn . I lost a DVD writer and a 500 GB HDD because of IDE to USB adapter powered by a poor made Chinese power supply

[@discipleofgod5948]

I like watching your videos but you're ruff as fark. Would you want the mother board molested like that? Each repair is a piece of art mate. Lol get a grinding pen from Northfield Fix also please. Catch you next time

[@johnathanasiou9284]

Most high reliability, idealistic repair techs would spot the heavy burn marks & write off the laptop, costing the customer even more $$$$ because now they have to source a new laptop. If Sorin using his "dodgy" methods can get the laptop running, it simply buys time for the customer so they're not forced to buy a new laptop immediately. Furthermore, spending extra job time grinding out PCB layers may be counterproductive & damage deeper signal & power rail layers hidden deep in the substrate creating an even worse problem. The laptop doesn't cost much & your repair approach means the customer when you give them an expensive repair bill will say "keep the laptop" ie your repair shop lost money!. I've worked for high reliability industrial repair shops repairing high value items ie more "fat" to be able to do things like what you mention. I've also done some work in retail repair & not only do you have to be like 10x faster, you'll skip a lot of the "nice to haves" because most customers won't even appreciate the repair, unless they're a tech & its an entirely different ballgame. Mock Sorin's repair all you shall but as economic conditions only further worsen globally, other cheaper techs/repair shops will get repair jobs & you'll be bypassed & lose money!. Personally, I find his repairs interesting & nothing wrong with learning a new repair approach, especially if it can help with techs 2 mortal enemies ie time & the accountant (repair costs)

[@discipleofgod5948]

I hear what you say about making money, if I gave the laptop back to the customer like that I wouldn't be able to sleep at night. Nothing wrong Taking 10 minutes longer or having a little pride in your work while maintaining professionalism. Imagine being the next ET to work on that laptop, you'd open it up and see the previous repairs, and automatically give it a no fix.

[@johnathanasiou9284]

​@@discipleofgod5948 your extra 10mins of time simply won't be acknowledged by a customer & furthermore, an even cheaper retail repair shop management will likely let you go from their team because you're costing them way too much money as 10mins on 10 jobs is seen as 100 wasted minutes & lost revenue. I have worked in both industrial electronics where my company management insisted we do quality work, had sent us continually do to training on SMDs & high reliability soldering courses & we did simply because industrial electronics products from the US typically cost a lot of money & customers favour reliability & IP6x dust ingress protection over unit/repair cost but I've also worked for retail cut throat shops like Sorin does & they're an entirely different mentality as even spending an extra 10mins on a job to them is seen as wasteful & I feel this situation will only worsen as the global economy falls further due to out of control government spending & continual sovereign debt borrowings which people seem to have nil issues with. Although many financial stable customers who appreciate quality will see your point, sadly, many low budget customers who will complain if you charged them $1 more for a repair (or will try crunch you down even $1 less) will unfortunately notice the difference & will likely raise objections in paying the repair bill putting ones position at a tech under threat for non economic viability. Sorin is playing a tough game doing what he does as I feel he's versed enough in quality repair practices but this isn't the repair environment he works in. I wished I had a dollar for every tech who was let go from roles because cut throat money hungry management crunched their techs for even spending 10mins which is why I don't work in retail customer shop facing IT anymore as its crap!

[@johnathanasiou9284]

​@@discipleofgod5948 Even an increasing number of IT MSPs these days are starting to crunch down on techs for spending even an extra 10mins on jobs. I wished I had a dollar for every bodge job I had discovered by MSP IT techs who failed to do the work on customer servers & workstations which they had happily invoiced for ie discovering skipped OS for years & not following vendor app patch recommendations, neglecting router, switch & driver updates leaving systems vulnerable, leaving simple passwords on admin/root level service accounts (all undocumented!), not maintaining proper offsite backups & when I had worked many times in MSP overseer roles for clients, omg how MSPs all got upset with me when I had discovered all their cons & the myriad of bs excuses they claimed in response!
