Crap.
Thank you. You gave me some ideas, which I will try on my ThinkCentre that isn't turning on
We're do I download the software for this
thanks bro
You just measured some components to see if they get power... Did nothing, but computer started 😂. Made me waist time! Erase this video!
Hello What is the brand or the mark of Freezer spray that you use ? If possible most informations . Thank.
you helped me thank you
Excelente vídeo, muchas gracias.
My friend from a technician to another I thought I should inform you that with most notebooks including Connex notebooks you have to press and hold the power button. There's a difference between notebook and laptop's
Stop distracting yourself with that iPhone! It's totally irrelevant.
Bro is high and still recording tutorials
Same story to mine but it only show light but no display i tried removing the ram and insert it again but still wont turn on
All lenovo computers have a Hardware maintenance manual, with steps on how to replace parts and open the computer.
Hola, en el datasheet de ese dual mosfet, los pines [5, 6] están unidos y los pines [7, 8] están también unidos, pero en el motherboard los pines 5, 6, 7, 8 ESTAN UNIDOS Los drains de ambos mosfets están juntos en la motherboard ¿Es normal eso? ¿O estoy viendo mal? Eso quiere decir que si mido con el multimetro ese dual mosfet fuera de la motherboard marcará en continuidad los pines 5,, 6, 7 y 8 ¿cierto?
Please help with lenovo g50 A-362 REV 1 that you used to repair 🙏🙏
When you have the charger plugged in, did the charging indicator light change colors, or have a sequence of flashing lights? PD1 is cooked!!
Can you fix mines?
Hi my friend. How can i open the device? Is impossible to unscrew
how to know if i have the correct capacitor to replace
Thanks man, i have solved the problem
Not clear what u are downing
Helpful video love from india earned a sub
What was the intro?
Pls sir… what are criterias for changing the first mosfet? Must it be from the same type of laptop/motherboard? Or any mosfet with same number? Or just change from anywhere? Or can u replace N channel with any N channel and P channel mosfet with any P channel mosfet even if is not the same number? 🙏 pls help me

Sir in a situation where you bridge the first mosfet and the charging ic got damage. What will i do? I bridged my first mosfet and now the charging ic gets hot each time I plug in my adapter. What’s the solution
Obrigado Pelo Video.. me ajudou aqui...
Bro stop repeating yourself and fix your mic, its so anoying watching your video like this
I have 2 Dells (E7250 and E7450) with this issue. Adapters are Dell OEM and they work fine with other laptops. Found an old Dell PRO3X E-docking station in garage and both laptops charge, BIOS indicates correct wattage, and faster performance. This E-dock works with all Dell E-series laptops up to E7470 and is cheap online. Note: The dock requires a 90W adapter to operate (also cheap online).
Good sir
Were those EC chips the exact same or similar codes? I'm in South Africa and I cant find a specific EC chip and ive already taken apart 3 laptops with the same model number. The motherboard layout is exactly the same among the boards but they all have different EC chips.
So the board it's dirty? That's all the problem?
Finally found another good troubleshooting channel. Awesome!!
Thank you for this :)
where are you located?, i need a repairer for my slimbook
Is there a part two to this video???
Can I unlock a1466 MacBook Air 2020 in same process
Great to have you back brother. Can you recommend a good microscope from Ali express or from anywhere locally?
That's pretty amazing. I've been in the industry for 45 years, and I've never seen anybody troubleshoot a shorted SMT capacitor just by visual means. Troubleshooting these capacitors are almost impossible when you have multiple ones all in parallel with each other, so this is a great way to help isolate a defective capacitor. I am looking forward to trying out this technique at work tonight. Thanks for the video and teaching this old dog a new trick.
Best tutorial
"We have to use de common sense: (proceeds to brush the motherboard with liquid and a toothbrush) yes, very much common sense used here
Hi, is it still worth to read BID from laptop with this issue after it has been tried to flash BIOS using HP BIOS recovery USB with latest version? I have no backup of original BIOS.
If you have a CPU with a TPW (maximum allowed wattage) of 65W and a VCORE of 1.2V, for example. Then you can calculate the dynamic resistance to U^2/P. In my example this would be 1.2V^2 is 1.44 divided by 65 is the result 0.022 Ohm. The allowed current is 54 Amps! But time flies... So we have a TPW of 240W and a VCORE of 0.9V, for example. Then the resistance is 0.0033 Ohm and the allowed current is unbelieveable 266 Amps! So we need better multimeters.. 😂
solution 100.100 god job
Give it up half the time couldn't understand a word you said or even hear you .and resoldering a compent add some flux
this is basic, when mesuring for short in beep mode and the cpu is onboard, it shows short with low resistence, ???????
I think he wants to point out, when it's just a low resistance and when it's a real short. A high-side shorted MOSFET can be easy found. A low-side short can be a real short or just the mentioned low-resistance. So, in another video he dismounted the coils...
Had an Hp laptop lasted for 7 years the problem is the battery but bought this Mecer in 2022 exactly after a 2nd year its not switching on 😢
