Laptop Destroyed By Just Turning It On - But Why?

[@reinierwelgemoed8171]

Bro I've watched most board level repair guys on KZbin and You are the best to watch.

[@dellpartspeople]

😮Wow, that means a lot! I watch all those guys, too. I am trying to create a seamless experience where you feel like you are there with me. Let me know if there is anything I can do better.

Iceman did it again! The perfect amount of flux! Greatest Dell technician to ever live! You can raise the lost pad surface with extra flux or reinforce the trace.

[@Urgleflogue]

Excellent! I'll never dare to do a repair like that at home, but I'm fascinated by people who are able to do it and by the process of doing it! :) It's like doing a work of a detective tracking down the culprit plus a ton of useful auxiliary information. Great video!

[@dellpartspeople]

Thanks. Yeah, I like to think of myself as a detective following all the clues.

[@sivanandkashyap5893]

Absolutely love this. Wish I heard the tape tip before because while I was fixing my power button misalignment I damaged the connector.

[@dellpartspeople]

That’s a bummer!

Great job and brilliant presentation. It would have been interesting to know which value the replacement cap had. Maybe next time you can include your approach to identifying the value of the burned capacitor? This is the first video I happened to come across from this channel. I will definitely look out for more. Keep up the good work.

[@dellpartspeople]

Okay, I can definitely do that. Thanks for the feedback, and keep it coming!

Just WOW! I've fixed 'stuff' before BUT not like you do!.....Awesome!

[@drcyb3r]

It's almost always a tiny capacitor that is bad. I have the feeling that manufacturers do this on purpose to make you buy a new device again. I have repaired so many completely dead devices and most of the times it's either a tiny capacitor that has a short or a bad power IC. Inside a once expensive firewall/network appliance there was also one tiny capacitor that made the whole device stop working. As it was part of a fan controller circuit that was unused in this model, I just removed it and everything was fine. Also there were so many capacitors on this main rail that even if this one tiny capacitor was missing, the fan circuit would have worked. A tiny 1ct component makes a once 1000$+ device unusable. And as datacenters won't repair anything and just replace it with the same device, it's a big win for the manufacturer. Another thing manufacturers love to do is to use eMMC storage for he OS of the device like in NAS systems. Those chips don't have a high lifespan and also often fail because they start to loose data and the device won't boot with a corrupted file system. After replacing the eMMC memory with a new chip or even an SD card, it works great again if you have a method to reinstall the OS. I now have a great Keysight scope for only 10€ where I managed to fix the bad eMMC storage.

[@andygozzo72]

those caps are notorious for going dc leaky or short and burning up, too much miniaturisation!

[@cesaru3619]

Is there a way to notice what brand smd capacitors are? I'm tired of cheapo no brand ones, I don't trust resellers.

"It's just a capacitor!" Can't tell you how many times a client has told me that. Sometimes you get lucky.

[@keithnsearle7393]

You did a good job there.

[@noanyobiseniss7462]

FYI, in these instances the fastest way to find the blown component is to just smell the board. ;)

[@evionlast]

Man, is that a professional recommendation? What are you on about... JJ

[@dellpartspeople]

Oh, yes... The Smell Test! 🥸

[@noanyobiseniss7462]

@ And you can use your sense of touch to find failing components just by running your hands over a board to locate the heat. Back in the day we didn't have all these new fangled tools that convert everything to eyesight. To find a break in the lines back in the day we;d shoot 60 amps through a underground cable and look where the smoke came out of the ground. :) And that was when I was working for the FAA, before anyone gets their panties in a bunch.

[@EdnaR.Mattingly]

Suits to watch how you explain alongside the repair. Can i learn too?

[@thelifeaofyoutuberday5822]

@dell-parts-people If the battery wasn't bein detected then it wouldn't show the battery state or battery health, measuring the battery voltage on the connector will measure the voltage inside the battery so whatever voltage is shown from reading it at the connector is the same result you would get if you checked it on the actual battery itself, so since you got 0 to -0.014 volts on the battery it was COMPLETELY dead and had no charge in it hints the missing info. TLDR: Battery voltage from the connector and battery voltage on the battery itself are the same and the 0 volts on the connector means the battery was completely dead

[@dellpartspeople]

Well, it is not that simple. If there is a short on the motherboard, the BMS (battery management system) chip on the battery is told about it, and the battery output will be shut off, showing 0 volts. Now in addition to the battery being shut off, it was also no longer being charged, so the voltage on the battery can get below 0%. The way battery charge is measured is based on the voltage of the battery. This battery is a 3-cell, and the nominal voltage of each cell is 3.8 volts or 11.4 volts. Nomial voltage is 60% charged, fully charged will be 12.60 volts, and 0% charge will be ~10 volts-ish. If the battery is below this, it will not show any charge state, like it did once the short was corrected, but after a couple of minutes, it corrected its charge state. If the battery falls below 9 volts-ish, the BMS will shut off the battery and will not allow it to charge anymore. I hope this helped!

[@Kiryl_BTW]

What my parents back in the day thought would happen if you turn off the laptop with the power button

[@dellpartspeople]

hehe 🤣

[@jacks5kids]

Clumsy soldering technique here. To remove the capacitor, a much safer way is to add some solder to both ends, then use two soldering irons at the same time, one on each side of the capacitor. He should not have applied power with the capacitor absent. That causes high frequency AC to be applied to the rail and can easily destroy other parts.

[@dellpartspeople]

Thanks for the feedback. -Two soldering irons at the same time is a very interesting idea, but I am not sure it would be a safer way. -As for running the laptop without this capacitor... This is just a filtering cap, which the main power rail has 100s of them already on it. This one was just the closest to the MOSFET. This laptop does not use AC to power it; everything is DC, except for the PWM signal on the gate of the MOSFET, which the capacitor was not connected to.

[@jacks5kids]

@@dellpartspeople No, its not 60Hz AC that I was talking about, but the square wave of a few hundred kHz that the buck regulator feeds via an inductor to a capacitor. Take the big capacitor out and you are left with a square wave ready to do lots of damage.

[@jacks5kids]

@@dellpartspeople Two soldering irons is not safer for your fingers, but it is safer in that you are much less likely to rip pads off the PCB

[@FrancoCoccini]

😮

[@rocketscientist007]

How did you know the value of the capacitor?

[@sleepwalker6825]

They normally are 10 Microfarad Caps and from Experience You tend to go with Unless it's a CPU OR GPU cap which maybe 25 Microfarad ...

[@knowone6214]

good job.....do ya get headaches using that microscope ??? LOL

[@dellpartspeople]

Actually, no, but my eyes are starting to get bad, and I think I will need glasses soon.

[@ElektroTechNL]

Nice one. It was welded haha

[@Kazeshini11]

Maybe I missed it and if so I'm sorry but what could lead to such a result ? Is it just bad luck or too many possibilities of this happening ? To specify, to have the capacitor blow up.

[@artmanrom]

He said that he couldn't know if the cause was just a faulty capacitor, or the capacitor was just a symptom of something else that has pushed the capacitor beyond its limits. Only the next video will reveal the truth.

[@dellpartspeople]

Most likely heat related.

[@reinierwelgemoed8171]

How do You like that UniT multimeter? I have same one and really like it. I do mostly automotive and cnc machine electrical work.

[@dellpartspeople]

It is okay, but what I do like is that it connects to the computer so everyone can see. It is not the fastest and most sensitive, but it is fine for 95% of what is needed for this type of repair.

[@theaboladrome1755]

What soldering iron do you use? Which iron would you recommend for a basic level learning stage technican?

[@dellpartspeople]

You don't want mine. It is about 20 years old at this point and has not bells and whistles. It has a single on/off switch and no temperature settings. It is very powerful and has plenty of tips to choose from, but there are way better ones now on the market. You don't need anything fancy to get started. Just buy good flux and good solder, and make sure the iron is more than 30 watts. It is a Metcal MX-500P, but the older one is without a screen. They sell used on ebay for about $300.

[@easyhardenduro9847]

Have you ever seen a usb that has power but no data tranfer?

[@dellpartspeople]

Yes, I am assuming you are talking about a USB-C port. These ports can get broken pins and stop communicating. The positive and negative pins are on either edge, and all the data pins are in the center. The port will probably need to be replaced. One test you can do is just rotate your plug connector 180 degrees and plug it back in. The pins are set up in a mirrored pattern, and it can work when plugged in one direction and not the other.

Is it possible to repair a ribbon cable? I have a Macbook Pro SATA cable. It partially tore. Would the ribbon melt at 200 C? The amount of copper they used is tiny, it is way too thin.

[@stevedebeukelaer1424]

Hi nice fix i got a strange issue with dell lattitude e5550 who depletes his battery when off it charges fine the battery works . But when it is off depletes when i do battery report it says 0 cycles charging i changed 2 original batteries. Do you have any clue how to fix it?

[@dellpartspeople]

Interesting. I just want to be clear on the problem. It charges fine when it is off, but depletes when it is on? This issue could be caused by an under-powered Dell charger. First, make sure you use a genuine Dell charger. The minimum that this laptop can use is 65 watts, but if you have the i7 version of the motherboard, you will need 90 watts. The laptop battery will help run the laptop if the charger is under-powered. I hope this helps. We sell them if you need one www.parts-people.com/index.php?action=category&id=140&subid=537&refine=power+adapter

[@stevedebeukelaer1424]

@dellpartspeople Thank you for the response . No i use original 130w and have also 240w original charger . No battery depletes when the laptop is off. When it is shutdown and lies on table. If you put charger and use laptop battery charges fine. That is what i find strange abouth it. Thank you

[@Ananya_108]

Sir! Are such repairs will last long our system as it would work without any mishaps?

[@dellpartspeople]

There is no way to know if and when one of these capacitors will fail, but if you keep your laptop clean and cool, it will help prevent this.

[@manga99uk]

Just wanted to ask a quick question why just dell laptops? I know dell is like second to apple for laptops but there so many other big names making laptops. Why not fix them to?
