HP Laptop No Power - Troubleshooting Short circuit - Watch component blow on camera

[@em0_tion]

Another great episode of my favorite TV show. 😁👍 That ugly cap has been bugging me ever since 1:57 😠🔥

[@NorthridgeFix]

Yes you're right. That cap looks bad but it's testing good. I ended up changing the Mosfets again this morning along with that bad looking cap. Short was gone like before. I powered on the device and Mosfets went bad again. Laptop is going back to the customer unfixed unfortunately. .

[@em0_tion]

@@NorthridgeFix Hahaha You always foolproof your videos, so i knew you did! That job was too good of a tease. You gave it your best. 👍 As Hristo Stoichkov says - "Sum tie win, sum tie lewn". 😂

[@ksngs78]

@@NorthridgeFix this is VCC_CORE core line where blown resistor and capacitor you got the short. Most likely a rare event happened - cpu itself is shorted. IC is battery charge controller. And mosftest near by IC gives VIN line

[@shadowarez1337]

Was going mention that cap amazing work as always HP should seriously offer you a consultation job to help them design better labtops you seem to always be fixing these things and would have a great many ways to help them improve this line.

@ARI GOLD EXPERIENCE but it's sad coz I have a laptop with a similar problem that, similarly, led me to a rabbit hole. I think the processor might be shut, in my case :( I had great hopes that this would give me some pointers. Nice video, tho ;)

I think your work is amazing. Some of the process you use today were simply not available when I went through college, and I totally respect the new advantage processes I'm learning. I think your skills are spot on, to the point, and well equipped to get it done the best way possible. If you say it's a no fix, after learning what all you go through here, I more than respect that. It's not time effective.

high respect to show these repairs ( fix or no fix ). Your expertise has te be paid anyway. After watching your videos, i feel more confident for my own small repair shop. Im often presented challenges. Sometimes im too afraid to even start the repair. But after watching this, even a no fix seems acceptable.

[@ictrepairs6963]

Non ritengo sia proprio così però fermarsi così presto significherebbe dichiarare il 90% delle riparazioni no fix il che non renderebbe certo il suo lavoro remunerativo. Ha buona tecnica però questo si.

This Circuit that blow is switching power supply. Google about it, simply 2 mosfets, 1 Coil, capacitors and driver.

[@trolojolo6178]

This guy is just learned everything diy. He doesn't know how to properly proceed with fixing motherboards. It begins with reading the schematics to understand how the device works. It doesn't have a charging issue, he already put a fully charged battery inside from a donor laptop and proceeded to remove the ic that is responsible for charging the laptop. Big time fail.

Crazy when you see something on camera before he sees it, and it gets looked over several times. Sometimes having a second set of eyes is great! Maybe consider livestream repairs?

[@johnpowers1275]

Curious why didnt use the spare board instead of doing that work? Love the videos tho, I tinker some with electronics as a hobby, and have learned a lot from you.

[@N1Zer0]

I'm guessing the donor board is just a similar board not an exact type of board.

[@southerncharity7928]

My guess was CPU was blown on donor

[@giuliocarlini6681]

If you have a death cap, how can you know the new cap caratteristics to replace the death one? (if you don't have doner board)

[@golski1273]

by the cap's size and the circuit it was used for if for instance schematic diagram and donor board isn't available

[@giuliocarlini6681]

@@golski1273 alle the caps with the same size are the same?

[@golski1273]

@@giuliocarlini6681 no. they have different values. the size and the circuit will give you a rough idea of the capacitor's value.

[@pbakai182]

only real accurate way without a donor board is to read the value on the schematic.

[@jonasduell9953]

1:59 bottom right corner capacitor looks literally split in half, skips it, sees tiny hole in resistor 😁

[@trolojolo6178]

I was screaming at the screen that he completely ignored that part.

[@oeokot92]

So, your meter in diode mode makes a long beep when there is no resistance to ground (a short) and a short beep, when there is no short. In that case the short beep is comming from the charging of the cap?

[@bombswabs3041]

[@diesalweasel]

You can't win them all pal .great video love watching . Out of interest when you injected voltage in to that cap .does it matter what side of the cap ?

[@DannyBokma]

Why didn't you remove the big red flag -> the capacitor that was fractured?

[@Rodox2k10]

...because it never indicated that it was shorting? Fractured or not, it was still functional. That's the mindset you HAVE GOT TO follow if you attempted to fix a laptop and didn't have the same model to extract any components from. So let's assume you try to remove that cap anyway because you didn't like the way it looks. Great, now you gotta find out its working voltage and capacitance. With no schematics to go on about and no capacitance measuring device, good luck with that.
