This laptop belongs to my cousins son who was crushed when it died on him. My aunt contacted me when Geek Squad gave them an estimate of over $1,100 to repair and asked if there was a way to get it fixed. Unfortunately there is nobody I could find here in central Illinois that does component level repairs like this. So on Monday (11-4-24) this laptop was sent FedEx to NorthridgeFix in California along with the reasonable expedite fee. On Thursday I was emailed conformation they received the laptop and repair had begun. This morning (11-8-24) I was greeted with an email that the repair was complete along with an invoice and easy to follow link to pay online. I cannot express how grateful I am that NorthridgeFix exists, does these repairs, and was professional and top notch to deal with. Thank you very much and keep making these great videos.
Hi Alex, I'm very impressed that you actually do take the time to read your fan's comments. It was me that made that comment about, "It looks something like this" in your previous video and I was pleasantly surprised you mentioned something about that at the beginning of this video and on some level, I felt validated as a human being at that moment. So thank you and keep up the awesome work. Really enjoy the content you put out.
I am sitting here with a smile on my face,, you actually read my comment about it looking something like this...I have heard that saying all my life and i always replied like i did to you.. i am 72 now,,, Keep up the good work i really enjoy your videos..
Oscilloscopes seem to be useful for repairing vintage computers where stuff is less integrated. If the processor clock is external, you can observe it. You can also observe all the individual address and data lines. I've seen a video where they found a signal for an address or data line that looked way off. But using an oscilloscope is not so much for newer computers, where the clock generation is on the same chip as the CPU, and most memory accesses are to the internal cache. You probably don't need to check address or data lines that go to RAM or peripherals on modern computers so much anymore.

I don't think Geek squad is allowed to open laptops. Where are those components manufactured? What kind of quality control/ quality assurance is used? 🤔 Could a small heat sink or copper shim be used to help disipate heat from those MOSFETs?
Hi Alex, I've watched every ASUS laptop video you uploaded and it gave me hope that maybe my laptop can still be fixed. I have a liquid-damaged laptop that is not powering on, but the laptop is charging, and the charging indicator is on. There is no power indicator when I press the power button, but every time I try to power on the laptop with the charger and the battery unplugged, the mouse light turns on for maybe less than a second and then turns off. I've brought this to two repair shops, and they say the motherboard needs to be replaced. Do you think my laptop is still fixable? (I also noticed that the power is heating up or maybe somewhere that area) Thank you, and I hope you see this.
I hope I get to use the one I purchased eventually. It hasn't been on yet, though I'm just getting my feet wet. Great video thanks for sharing your knowledge.
Everyday when someone says "Trying to find a time to do this & that" means they never are going to do it in their lifetime and this is usually always the case.
Please do a video explaining in details how to know which mosfect to replace a damaged one, things like the Moffett number and where to search for if there's no exact board and such🙏🏼🙏🏼🙏🏼
Its not to difficult. and theres many videos of testing mosfets for failure. picture them like a lightswitch in your house. Mosfets have usually 3 main points. The source, the gate, and the drain. power comes in from the source, and out the drain. but they need power on the gate in order to allow electricity to connect from the source to the drain. so in the lightswitch analogy. power comes in from one side of the switch (source) and then out to the lightbulb from the (drain). And the actual switch that moves up and down is the (gate) Only difference is the mostfet uses power to flip the switch (gate). And the lightswitch uses your finger. The numbers you have to google to get a diagram of the mosfet to see what pin goes to what
@mystery504life yh thank you so much, but I don't think you got my question right. I'm asking about replacement how to find which mosfect to replace which of there's no exact donor board 🤔
@@adedokunoluwatobiloba1683 okay i think i understand. There are a few different websites that sell replacement mosfets and such. Mouser being one of them. Digikey is another. You can type in the numbers written on the mosfet your looking for, and they will sell you a replacement. But Mouser and Digikey are the most used parts suppliers
The capacitors are between the output of the MOSFET and ground to remove any A/C from the output and leave just DC power. When they short, they connect the output of the MOSFET to ground and cause the MOSFET to overheat.
copper, by which capacitor is connected with that mosfet (and on both ends), is a great heat conductor. and on such distances they might even heat up via air due to very close proximity.
I have ASUS ROG STRIX 17 G733PY 2023 with AMD Ryzen 9 7945HX and RTX4090 It was twice in the repair already, they have been changing the motherboards. 2 weeks ago send again to repair. It has the same problem again and again. After some time when everything is fine you are powering laptop on and no image on display, but the laptop works. I can manipulate with the keyboard and do restarts. For example ten restarts in a row and display shows up again. :D Had to write a letter to change this laptop. Now waiting, it seems they are trying to fix again. So after two weeks I got news that I can choose new laptop So took scar 18 2024 with i9 14900HX and RTX 4090 And so far no any issues
Components FAIL because of small defects in manufacturing. That's why components have a +/- rating for tolerance. A Components may function fine at first but after time they "Wear" electrically, and then all it takes is a change in power, current, voltage, that upset the component and it fails. I have seen components even short out due to SHOCK from hitting the item it's in, microscopic CRACKS and Fissures can form while a component is HOT from operation and a shock wave going though it can cause it to short out.
Alex : Somebody in the comments wrote the "laptop does not look something like this" but "that's the laptop" and that's 100% true so I'm avoiding having to say that in the future. ... Alex : That's exactly how the laptop looks like and let's read what the customer said. 🤣🤣
Thanks Alex. I am pretty new and I did buy a scope . It’s a cool device but I was thinking I am doing it wrong since I found a multimeter was more useful :)
My asus rog stix 3 wont turn on ... last time i took it to geek squad and they got it working but today it wont turn on ... considering something like this .. just dont have much of a budget... how much does something like thus run ... id have to send it and such so that is another fee ... rog strix 3 laptop like three years old ... ive had to hard restart often recently cause it simply wont turn on .... but that isnt working this time ...
I am thinking of using the oscilloscope for fault finding the keyboard with some dead keys. There is no reading on the keyboards cable so a multimeter is no use.
I don't know what's wrong with people's when they think oscilloscope was used in repairs, actually oscilloscope are mainly used for research purposes when you do reverse engineering in circuits or when you doing network engineering
They were used a lot many years ago for TV and radio repair. Back then, individual parts were replaced. Now, most TV repairs are done by replacing whole circuit boards because most shops don't have the experience Alex has, and it's much easier to replace the whole board. With TVs, most of the cost is the screen, so board replacement is economically feasible.
Alex, i'm an hobbist tinkerer since more than ten years, i seen so a lot of things, so i think i have the answer why they fail, and why also other faults happens, if you want my version, ask me.. bye..
Ok so you have no time to do a "thesis" on what caused the MOSFET to fail and it's true that a repair shop needs to be run efficient like you said: fix - invoice - next, etc. and I agree. It is not your job to do an in-depth post-mortem why what failed in which order. But then again, if you are so efficient, why did you waste your precious time to remove the two capacitors when it was already clear that the fault is at the MOSFET?
As he said in the video, the mosfet getting hot does not necessarily mean that is the faulty component. Most of the time it's a capacitor and it's faster to remove those so makes sense to check those first.
A shorted capacitor across the output of the MOSFET will cause the MOSFET to overheat. It's much faster to remove a capacitor than the MOSFET, so Alex removed the capacitors first. He said it was unusual for that particular MOSFET to fail, so he didn't jump to conclusions. When a MOSFET that usually falls overheats, he'll go right to removing the MOSFET.
Exactly my point when I said that the only people who think they need an oscilloscope are the same people who just think it looks cool on their bench or desk.
It depends on what you need to do. If you're designing a power supply or anything related to power electronics, then you need to check for the output waveform, the presence or magnitude of harmonics, etc. Also if you're designing a PI or PID closed loop system, then you need to check for undershoots, overshoots, etc. There are also additional examples where you would be using an oscilloscope. But for a repair shop like this, Alex almost never used it.

i can see you get so much joy from when the laptops turn on after ur fix with ur smile great job my man
Better then factory!!!✊✊
I am sitting here with a smile on my face,, you actually read my comment about it looking something like this...I have heard that saying all my life and i always replied like i did to you.. i am 72 now,,, Keep up the good work i really enjoy your videos..
i miss you saying "the laptop looks something like this" it is your unique signature
Geek squad is like a clinic and Northridgefix is like the hospital. Turns out the patient needs surgery and now it's recovering better then factory.
Geek Squad is like a pair of chimps with those giant "WE'RE #1" foam fingers poking around the engine of a Ferrari and slinging feces everywhere.....
😂
more like a school infirmary vs a level 1 trauma center.
Great fix again. Best part is the smile when its fixed- "We got it"
"We did an awesome job."
SUPER ! Loved the OSC story LOL
I watch your videos from Cameroon, i have your notifications turned on. It's 00:21 am here. Keep up!

Come on man 🤭 something like this is ok. Even in romanian language we use to say it this way. Very grateful for your videos 🙏 keep up the good work 😁😌
Sei il migliore amico,godo nel vedere i tuoi video.
From india watched almost all your vedio
I love the work you do
Hope someday I get a chance to meet you
nice work as usual!
Just live the videos and makes me do more repairs my self 😊
I really appreciate an update on my laptop HP Omen 15

great comment about oscilloscope, but did You try component tester ? and what is you most useful tool on the bench ? Fluke or ?*
Amazing as always thank you so much for the shared knowledge 🙏
I'm from Brazil and I always watch your videos.. I love all your videos..😉👍
Alex, why not place the camera in an overhead position. It will be much more convenient for you also.

Amazing 👏 🤩 💻👨🏾💻Fixed up
Excellent work.
You need an oscilloscope if you want to monitor data packets, and data path and bios activity, and generally high frequency signals😊
Everyday when someone says "Trying to find a time to do this & that" means they never are going to do it in their lifetime and this is usually always the case.
When does nf-oscilloscope go on sale?
This lad better than LR
Better than factory.
Every time I click on a Northridge Fix video I hope to hear that 😂👍
Great Video!
Can you tell me something about Lenovo BIOS Update gone wrong?
What can i do?
Laptop starts but no post nothing
I call Geeksquad "parts changers". They don't do what we do. They can't repair at the component level.
How do manufacturers solve the distribution of bad parts evenly across all notebooks?

Does big boss re-apply thermal paste/pads (when applicable)before reassembly?
Of course. He Has to.
What is the word you use for the chip that is short? Sounds like mascot or moscot to me. Cheers
Mosfet
can we see your multimeter on the screen plz
Love the genuine smile when he sees that it is fixed..."Yes...yes".
How does the laptop know the heatsink is not attached?
Technically how can the MOSFET heat up if the short is on one of the nearby capacitors?
The capacitors are between the output of the MOSFET and ground to remove any A/C from the output and leave just DC power. When they short, they connect the output of the MOSFET to ground and cause the MOSFET to overheat.
copper, by which capacitor is connected with that mosfet (and on both ends), is a great heat conductor.
and on such distances they might even heat up via air due to very close proximity.
yep, the infrared camera shows clearly the mosfet as a problem.,
Awesome ✌🏻✌🏻✌🏻
