Hp Laptop, dead, no power not charging, lets diagnose this together!

the short goes disappear because the man who will try to repair is a legend.

[@trinitrotoulen]

the short got scared because of legend :D nice one

[@JustForFun-up1hf]

After watching this video i think you reached the next level of laptop repairing, that laptop will repaired by laptop it self when you going to touch it. Thanks master sorin keep uploading video i’m still learning 😁👍🏻

[@melihcan7577]

You talking and explaining things is so relaxing!

That is called the Guru Proximity Factor, like when your car is making a strange noise, and you take it to the mechanic and once he wanders over to take a look at it after you've been waiting for half an hour and by then the car has stopped making the noise. Once the object in question is in the proximity of a Guru, it stops the problematic behavior. The Guru Proximity Factor. That is a real-life lesson...

Sorin, not only are you the best of the best in your profession, you have a heart to share your expertise in a manor that's easy to follow and fascinating to watch. Please accept these words from someone with a skill set similar to yours, "You are awesome". Thank you for sharing.

[@tinkmarshino]

Sorin, this was the best job! We all have run into this insanity where we go to fix something.. take it apart find nothing and it just starts to work again... Frustrating I know.. Because all of us that go to repair things be it computers, cars, washing machines you name it.. When they just start working we know that we have not fixed it properly and that whatever was wrong it will happen again.. Keep us posted if you find anything in further investigation.. or if it comes back to you again with the same problem.. Thanks my friend... carry on!

[@djtongi]

100% the cable... you moved it an the damaged part isn't connected to ground anymore and it shut down during movement once again! I think it's the section on the twistig point of the hinge. the cable is wrapped with "ground" and when the cable is damaged at some point, it comes and goes. OR.... ou said, that the screen got repaired before. Maybe the guy damaged the cable clamping it somewhere during reassembly.... but like you alredy said, replacing the cable is the safest and best thing to do. Maybe it's working now but closing the screen once or twice after assembling the whole thing, the failure is back and then you're just more pissed. Great Videos! Always love to watch!

[@BlackOpsJuJu]

Just Love Your Vids Have Seen Them all Can't get Enough of Them Love the Way You can Explain Things Great Job Keep it UP !!!!

[@xzoli8]

As I observed after more and more laptop repair videos are uploaded you start to explain in a more detailed way how to diagnose these issues, better like a good teacher ;) :D, theory and practice at the same time in a real scenario , we would like to thank you for sharing with us your knowlegde. In this way we can not just learn something but we enjoy to watch and learn laptop repairs. :)

[@papinkelman7695]

I don't smell anything Also: the lesson is good. We learn how to think, and in what order to think it in. We learn to make measurements to test our conclusions.

[@gassanali8667]

It’s a great lesson, Master Sorin! I learned that mysterious things can happen with electronics. It’s an accidental fix. You wanted a fix so you got a fix. The lesson was not less great. Like so many other comments also testify, you’re superb at explaining problems and taking things in a logical, step by step approach.

[@kevinmoore6954]

Thank you Teacher Sorin! This was a great video showing how a screen can cause problems. My bet is its the connector on the screen which wasn't installed correctly when someone messed with it. Thank you again Sorin!!!!!

[@alexandruit9416]

Te urmaresc cu placere pentru ceace faci si ma bucur ca modul tau de a prezenta o reparatie este detaliata si foarte placuta la vizualizare. Ceace faci este un lucru minunat pentru cei care vor sa inceapa ceva, succes si pe mai departe. Vroiam sa iti aduc la cunostinta ca din toate videourile pe care le faci uiti mereu sa verifici cablurile flexibile de pe placa sa vezi daca sunt intrerupte sau deteriorate, in rest respect

[@hores2020]

hi sir , I am from Egypt if you allow me to say that the problem was at the connector of screen it self we see this a lot here in home because of dust and you 've been saying that you smell something in this laptop so when you remove the cable you make it clean by luck and it's come to life . THX for every thing I learned from you .

[@ChillYourLifeNowAndForever]

Sorin & Louis Rossmann are currently the best repair guys around on KZbin. I always love watching your videos. You are the Bob Ross of repair ;-) Thank you Sorin

[@seidumomoh7791]

Excellent job sorin, keep it up

[@jonmobrien]

Except Louis is only Mac videos

[@metalacos]

Sorin every video even without replacing component is teaching video. I am trying to think in advance what is the next step and watch if I am right. I have to learn more about power supply to be able to buy correct one with and later on without short circuit protection. Keep up good work.

[@bardos]

From my perspective at 22:00, the cable connection to the screen as you turn it over is askew. We already decided that the screen had been replaced, or at least opened, I think the connection to the screen, the golden fingers, was not made properly. I could be wrong

[@erakan6121]

When the notebook fixes itself the disappointment Mr. Sorin has is priceless. Love the video, keep up the good work👍

It is always something to be learned. Always. And can be so funny at the same time. I like your relaxed attitude. Gives me giggle s.

[@kain1903]

I enjoyed the video and the way you explain your fault finding process.

[@BodziuM]

I had that problem and it was lcd cable problem, when I moved cable it started to work but I've replaced it anyway (it was cheap) and it is working now with no problem

[@alor6643]

Hi man!! I am strongly believe something going on with ribbon cable or some from your components had a an EMF, and you just discharged with the multimeter. The same happened to me with a lapto that didn’t charged. I touched accidentally the two pins from the battery charging pins and after a sparkle it worked!!!

[@chetanseth4976]

Hey man! I had the same problem, laptop completely dead, no lights whatsoever. After reading your comment, I removed the battery and touched the connector pins of laptop with a screwdriver. Boom! Laptop started working like a charm! Thanks for this comment!

[@ysteinBaeko]

I had the same problem on a HP EliteBook 840 G5. Based on your video, i slapped it around a bit, twisted, and knocked a bit. I'm not sure if the power light was on or off before starting to give it some gentle tough love, but it still did not show any other sign of life before I gave it a bit more love. Then I saw the caps lock light up for a moment... a bit more love and then keyboard light come on and it booted as normal. I have no idea where the problem actually was as I didn't even open it up.

[@168116Tkt12]

The straightforward diagnosis is the most important method for any electronic repair works! • with the right equipment, which we begin to learn how to select for use the faults are traced step by step until found! • Seen some with poor skills at even using the multimeter!

[@markkay8117]

Great vid! Had the same problem with the flex screen cable on dell e7440 . Because f the short in the cable few mosfets on the motherboard have died and power management chip was gone, partially burning the board.

[@MaxintRD]

Nice video, thanks for sharing. I have a similar HP Pavilion 15. Terrible design as it requires removal of almost all components just to replace the harddisk. My guess for this fault is a short in the pinched cable. As the screen was opened before it could also be that the connector was misaligned, causing a short on one end.

[@TheCavalry98]

Honestly this video was very helpful! I've had some strange ones similar (On Macs) that all you need to do is re seat all cables and it fixes it!

[@evilspeech9697]

We still learning master sorin! Thanks!!

[@sup2069]

I think I see what could potentially be the problem. Sorin mentioned that it looked like the screen casing had previously been removed. If that is true, the person who did it probably didn't have the cable all the way on the screen. Following up, when he disconnected the cable from the screen, no short. He then checks the screen inverter caps, fuse and mosfet, no short. He then reconnects the cable to the screen, no short. In summary, the only thing possibly wrong was the cable to the screen not all the way in.

[@mcgama88]

At a similar problem, I found a crack in board. Also. Here might be poor solder connection. Suspect ribbon cable..(also). Sorting to power issue and method in short finding was excellent in review. Thank you for your instruction to my hand. *McGary

[@coccoalino]

Awesome! Love your content! Here's an idea "How the laptops (not all of them tho) know what kind of power supply is connected and how to manipulate it?"

I saw some smog, no it ist'n is Sorin brains burning, hope someday we all know whats faulty on that machine. Thank you Sorin have a nice weekend

[@archemicon960]

Very thorough and precise instruction. Thank you sir.

[@robertisaacs5122]

Love the video..I did not know that a screen short would cause a dead laptop. Keep up the good work.

[@TaperedWiz]

Hi Sorin, if you check by replaying your video, you'll see the connector on the back of the screen was slightly out and not fully plugged in socket... May be that was the cause for the short. When you plugged out and reinserted again, you seated it in the correct way and the short is gone away... Ciao from Italy

I was thining the same thing.

[@sniper5406]

People: yaaaaaayyy the laptop is working Sorin: is sad that the laptop is working nice video Sorin keep up the good work, probably the ribbon is shorted when you move it just replace it and it should be fine

[@conspiracies1014]

If you look very closely you can see the very spot at which his fingers are at the bottom of the screen and when he squeezed the PCB board when the laptop loses power. The problem is at the screens ribbon cable where it connects to the left side of the connector. These types of connections that are in a lot of the Newer type of electronics are very problematic and are often overlooked by some of the best electronic technicians.

[@bedandbreakfastfan7088]

Indeed the worst case. Sometimes its just a corroded contact point causing a short and sliding the contacts across eachother accidentally clears it. Happens to me frequently the laptop recycling/repair business because we get a lot of dirty machines.. Makes it very tricky to know if your work is actually done.

[@mikecastilla]

Interesting, loose cable somewhere? , dirty contacts? micro expose of display wiring?. good video, thanks!

[@boogerhead0]

Display cable connector was not properly aligned into display female. Have seen this a few times.

Wonder if the ribbon cable was not seated properly , found that a lot on laptops but never a short like that

Grazy fault. That was interesting. Something made short, but what that's a big question mark. Thanks for great video!

[@MindYourBusiness1970]

Hi Sorin , I'm following your tip on learning electronics ,so I bought a faulty laptop +a motherboard for spare parts , that's the easy part ,the hard part it's the CPU upgrade , I have an i7 that seams compatibile (the board has an i3 no socket ,everything it's soldered on board even the RAM) I'm not asking for a video , but if you talk about this kind of things in one of your next video I will appreciate ,thank you in advance

Nice woolen gloves to work on a cat piss machine ! The screen cable is showing a flattened bend so probably wires inside touching and shorted. If you straighten the cable short is gone, happens a lot. Thanks your 'magic' ☺!

[@Siniad]

Fixed laptops for years without multimeter. usually things like this broken cables or screens... Broken hard drives are just easy swap. Rarely power jack was the problem and more often charger/charger cable damaged.

[@Tutterzoid]

Definitely Magic Fingers :D I would also go with replacing the cable .. seen that is a common fault before :)

[@McMallister]

There's a video that you teach us about mosfets where they open and close by touching them with a metal, maybe that's the case, you were checking the components with the multimeter and voilá! Maybe a component needed a bit of a charge, like a battery...

[@rick5078]

question. I have a hp laptop here that will not power on and I am trying to diagnose and fix myself. the charger is working perfectly, dc-in plug is working fine, 19v is reaching the motherboard. When I unplug every cable except for the power cable, the charger light is still not coming on and laptop is still not turning on. all the capacitors I checked are fine, I can't seem to find any short circuits. I am stumped, what can I check to find the problem?

[@massimilianobarresi.]

Thanks for this lesson.. but i don't understand if there is short to ground on screen (yep no the cable) when you put out the cable on the lcd end reinsert it.. the short to ground disappears.. it's very strange! There is no explanation on it! I think anyway that with gloves you can't check if there are any heaters on it

Sorin the ribbon cable could be faulty when it bent. Damage by touching the metal frame of the case.

[@spacedoutET]

I have never had an issue with my hp omen. Since I bought in 2017. Only recently noticed my charger would show a orange charge light for split sec then go white and not charge. At 1st it wasn't working and all of a sudden it was charging normally, so I just ignored it. Next time I used, it done same thing. I was checking the connector and seeing if loose. Again it just wouldn't work and then I noticed it decided to charge again. After about 3 times of this happening, I figured it would just sort itself out. Then today, it just wouldn't fix itself and now the battery has depleted, I can't charge it up. It just flicks orange and then goes off. 🙃

[@DumahBrazorf]

There was 19V on the backlight pins of the connector so eventually was the short on the 3,3V rail? Maybe the connector at the lcd panel wasn't properly seated, little sideway?
