Modern laptops are design to fail, not be fixed and simply thrown away, good old days everything was fixable, and parts and schematics available.
I opened up my turntable from the 70's and it had a schematic and extra replacement diodes inside.
100% agreed. Even new LED / LCD TVs are same..!
It's called 'planned obsolescense' !
Love your vids Sorin, it's my daily therapy....
Wish you all the best for this year!
This channel is one of the best on TH-cam.
I’m addicted to it why lie. ❤❤❤
Excellent analysis. another great video.
So much for The Environment..
Always remember to love your electronics and put cooling pads on everything! Especially TV video boards!
One thing with many of the HP laptops I've dealt with-the power buttons are obscure, and it's often not clear if they've been activated-they move very little.
Can't even design correctly an on/off switch!
I tell you, you are smart and I learn from you❤❤
👍👍👍Thank you for giving knowledge. and treatment techniques🙏🙏🙏
From the HP site: Climate Action Taking urgent and decisive action to achieve net zero carbon emissions across our entire value chain, give back more to forests than we take, and innovate our products and services for a more circular economy. Meanwhile produces throw away laptops that are designed to fail ...
I just realised that Sorin is an anagram of Rosin
Sorin, the LDO power supply chip is made by Richtek. 4E= is the part number and 4H730 the date code.. This is the marking they are using on all their chips.
if the wheel as you said make laptop work for few years then no laptops to fix for sorin 😢
Both tps chips are connected together with I2C data line with EC ic. So removing one will not allow laptop to power on. That is how all new laptops works now a days. Same goes with macbooks
That's why i recomend laptops that not charging through usb c
Another great job Sorin.... but is incredile how this company decide to stole our liberty to increase their profit and state that let them do it...... without any administrative and financial penalty.... obvusly they earn to.... it's disgusting... bye from Francesco Timpano from Florence Italy
Thanks once again for sharing your skill and knowledge.
That video is amazing, thanks alot
Hi Sorin, I enjoyed your video. It's very calming. I have a question, how do you know the power rail and where to test? Is there a video how to do it?
Perfect 👍
Hi Sorin! 🙋Thank you so much for all the wonderful educational content. I have learned so much from you it is absolutely mindblowing.
⁉ Could you by any chance do a video about test leads & probes please 🙏? I am at that stage now where I will buy a power supply & a multimeter with accessories. 👆I never miss a video btw.
Great video, thanks again Professor!!
Anyone know why these USB controller IC's seem to fail often? Doesn't matter if mac or win, they all have common failures with USB IC. Even the CD32xx series fail. There has got to be a reason
NIce video has always, but you won't check on the video if the battery was charging after the chip swap :( i think it was all ok😀
I had that same HP it always overheated like hell and I sold it, poorly designed the fans are very small
HP's thin laptops, such as the x360 series, are almost always plagued by battery expansion and death.
What about the partially melted caps at 9:13? Or is it residual glue from the plastic sheet?
I was thinking something, correct if I'm wrong, but if both pd controllers speak with the EC chip to allow it to work, couldnt you just find where the first working pd controller was sending the signal to the EC chip and bridge it to where the EC chip was receiving the signal from the second pd controller? I mean ok it would require to find the schematic of the ec chip on the internet to check for the point you could make this bridge with wire. It should work right?
They copy from the Apple, you know! One CD is dead, you need to change them all, not only the dead one :))))).
Before the new changing pd controler laptop was working from battery but wasn't charging
Two USB-C ports, one next to the other, its two power connections. If one fails both fail: actually makes sense.
You don't want to be sticking in a memory stick into a faulty socket ........ that you don't know where POWER IS
GOING ... thus possibly destroying all data on the usb-c memory stick. It just means you have to track down 2
power connector problems on one motherboard. Two diodes are not the answer because both sockets double
up as memory stick sockets. And every time you plug something into either socket ... the firmware has to figure
out what to do .... read data from what is connected, or, charge what is connected, or, receive power from what
is connected. Therefore when one socket fails: they both go offline until both are working properly ... until both
are fixed.
Hi thank you for this amazing work. I think I have the same issue in my laptop. Unfortunetely I do not have access to tools to make the reparation, I do not have sufficient knowledge either. Do you think If Someone buy the material I can take a 1 to 1 hour with you to make reparation together ? With a laptop having the same issue ?
i placed my dell latitude e6330 laptop on charge. But later found out that the the adaptor light is off, but when i removed the charger from the laptop it came back on. After diagnosing the fault i foubd out one of my mosfet was shorted to ground so i removed it,and now when i plugged in the charger the shorting has stop. i found out from the circuit diagram that the mosfet i removed is in parallel with the other one beside it. so i was wondering shouldn't the laptop be working when the damaged mosfet is removed
It'd be nice if you got someone to help you chop up the video timeline into segments. Feel like for new comers a lot of this information can be slight overwhelming, and breaking the timeline would definitely help the channel grow by catering a bit more to the casual person trying to get into this field.
Everything is designed to fail nowadays ...even people 😋Te salut Sorine, cu respect !
Sir Sorin what kind Of thermal camera you used thank you :)
All MacBooks are like this, cd3217 are serialized one to another
Amazing🔥🔥
Hello 🤝 you don't know what it's about, it's always about money. Manufacturers of all electronics do the same thing to a greater or lesser extent. They only think about profit. Everything is focused on consumerism.👍👍👍👍👍👏👏👏👏👏👏👋👋👋👋👋
Any device with USB C should be plugged into charge and not moved. The ports cannot handle the strain of the wire and twist eventually. I treat all my devices the same with this port as Ive fixed many :D
Yeah the barrel design was far superior.
They put an "and" instead of a "or", i understand because if it's damaged, should be fixed and not take current.
Just re-subscribed what's youtub doing?? I never unsubscribed!!!!
Sorin is it posible to fool the EC bridge data line and then remove faulty LDO .... ?
What is the reason of putting two charging ports then.
interesting case.
HP always have this weird bios/ec firmware, I try i5 11 and 12 gen, it always throttle/underclock for no reason, the temperature is very very normal (around 50° celcius), but the cpu core clock down to 400 mhz for no specific reason
I know some solutions but message keeps getting deleted.
@@harrydijkstra9936 youtube doesn't allow for link I guess
@@maklogetrich2378 Nope it was all plain text.
Program: Throttlestop, disable BD Prochot. Modify TPL power limits.
This might help.
@@harrydijkstra9936 I know throttlestop, but for a brand new laptop, isn't it quite weird?
Basic question, could someone explain how measuring 10 omhs between a random cap and another point indicates that it's the 3.3V line and it has an issue? Should be close to 0 ohms? Was that testing continuity from a plus to a plus on the same line?
He was looking for 3.3v on the EC chip, but the 3.3v had a 10ohm short to ground...that's how he knew the problem was on 3.3, it should at least be in the high kilaohms
The issue was, it wouldnt charge after removal of the defective pd controller.
And it wouldt turn on without battery..
Did it end up charging the battery?
@@klwthe3rd The battery was not connected at that point.
it's the EC chip that programmed if one of the PD controller is missing, it would not work/charged the battery
Omen 16" purchased June 2022 - screen failed in less than 5 months! Replaced under warranty - Screen just failed again for second time, HP want SIX MILLION NINE HUNDRED AND 50 THOUSAND RUPIAH ( $440! ) to replace it again. We are a non-profit who now have no laptop or means to replace this one for a more reliable and better quality brand. Be warned - the quality of Omen is absolute junk and a rip-off - I didn't see any issue with screens failing for any other brand like this. *We would appreciate if anyone could help us with this - since we are a charity, while HP just wants to profiteer.*
Where can we find the live broadcast? Please reply
Maybe they designed to protect the EC chip from the disastrous 19v death.
wait, because It works with one TPS, the problem with the battery was solved?
the ec chip don't allow to use charger if one pd controller is dead or missing, but if the battery has charge, you can use the laptop on battery power
both chip have to installed
HP is going down hill so fast, speaking from experience
typical hp decision, i just hate this company
But u had picture before with one pd controler, but it was no charging.
no, the picture was done with the battery. On usb-c it did not power on at all.
@@orange11squares Rewatched and you are right.. makes also sense now..
There's only a will for greed in this country. Designed obsolescence to ensure increased revenue, customer, economy, and environment be damned, as long as the executive managers get their slice (99%) of the pie.
The chips would have to generate 4V to get over the 0.7 of the diode
schottky diodes 0.2 v do the job...
@@skysurfhf Still needs voltage adjustment to compensate even for 0.2V would it not?
no, 0. 2 v is very low voltage drop@@mikX4
It doesn't even matter, this idea is not working at all. When you have a short behind diode ( Sorin drawn it with bad polarity btw ), there will by only voltage drop Vf of that diode ( 0.2 - 0.7 ) on its anode, no 3.3V from LDO - and that diode dies too from excessive current, actually ( depends on its Imax ).
Still LDO with diodes?
Happy to be the first to comment, great job Technician Sorin
Another example of why we throw away so much tech just beacuse it is designed to fail.
So much for the right to repair, how many will even bother to find someone like Sorin
to have a laptop repaired.
This one was not cheap when new, how many other brands are as bad as HP?
But is it charging ? please let us know Sorin
I believe it's charging, I've seen many repairing videos of this kind of HP laptop
Yeah. I never liked HP products anyway.
Do not choose HP laptops!
I lost it when Sorin searched for the power button after 3 days of the purchase of the PD loool
BQ chip, i think ?
t is not BQ chip, it is PD controller
cmon Soren..bad design maybe..design to fail? Why would HP shoot themselves in the foot? Ive worked on some spectre's that do not have this problem. Same as Apple. One CD3215/17 goes bad..you cannot power on device. Bad engineers..not designed to fail
Diodes are too expensive. Why doesn't Sorin understand this? /s
please sorin replace the introduction of hp or before opening it "we have a shit hp laptop to repair".
I m not surprised when see that is HP.... What a garbage firm.
What abt sumsung laptops ؟
Peterborough 🤣☠
SORIN - ROSIN INTERESTING
i dont know, whats nice is for you - but i cant share that oppinion. its not a nice one, because it fails - ok, its fine for your company ;)
That's why there called horrible product hp same as dell rubbish.
What abt sumsung laptops ? You think there good ?
@@user-il9eg2op6v do they do laptops wow and not just a phone company, when buying any computer or building one you got to think will it be future proof for upgrading and fixing that's the question you have got to think about.
✌✌👍👍
and world complains about e waste but making things no not last and make more e waste :D
You would be out of work if they made them durable.
no but it will be fixable
modern laptops are just the worst machines made in modern times fully bugged and made to fail the reason why they wanted to phase out old working devices so there's nothing to compare it with, and another thread ive noticed recently is the bloat on softwares and firmwares disabling them old perfectly working devices specially on phones
Hello Master!
I wonder when you will use probes power instead multimeter 😂
up
Is it charging?
