HP 15s-fq No Power, Laptop Diagnostics  

Sorry about the lack of multimeter cam. Looks like I forgot to include it in the export - not worth destroying the analytics with a reupload for that though, so it'll be back next time.

Just for a second I thought you were going to finish early... But at least we got a happy ending.

"We maintain a level of professionalism here", oh Lord.

When I started learning board repair, I found out quickly how important schematics were. Some RU-vidrs just post easy looking videos of shorted and broken caps and they give a quick explanation leaving a lot out. Also, I do have to say, this channel is the only channel that really has helped me learn board repair. If you want to truly learn board repair, this is the guy to follow.

Great video. You had me in stitches on the out take. 😂😂

the face after the comment about no comments at 20:08 is why I watched this

A blooper reel... that's a rare treat!

You really are a fantastic teacher, you explain things so well. I always look forward to your uploads. And you do great closeup microscope views of the board components. Big plus.

It's been great watching you progress over the years with your repairs. 👍

Absolutely love the outtakes, so funny!

Really good video man, well done on including the outtakes at the end too 🤣

cool! Power injection and thermal imaging! That was a joy to watch. Thanks, Graham.

I always learn things through your videos, electronics mainly and english! your way to speak for even no natives its really nice for learning. Very thanks mate!

Hm. That strangely named chip... two different takes about it at that. ;) Oh, and bonus outtakes as well.

The outtakes last longer than some dudes. What a coincidence considering the name of the chip.

Always stick around for the post-credit scenes....

I looked in on this repair because I have got one of these computers. Nice to see your fault tracing technique, thank you. 😊. My computer works fine, and I fitted a different HDD and loaded Linux Mint onto that.

Love your videos man, so informative and very fun to watch, I learn something new with every video, the outtakes are a nice touch, thank you for the upload! :D

This one gets better and better.

Thanks like the way you go step by step

At least you got a good laugh out of it. So it's a win in its own right.

Sorry, I missed it. What was that chip again?

great video. thanks

Thanks for the video, I'll come again next time.

I love your teachings, but I think it would be helpful to have another inset in the video of a shot of your meter readings as you're probing around.

20:10 the chip is not coming 🤣

If I understood correctly, the short was between layers of the board at that one point right ? You couldn't fix by cutting a small section of board away or micro-drilling a hole there etc, and re-routing a couple of traces if need be ?

Done watching, thank you very much for the informative repair video. I have learned significantly more troubleshooting & repair lessons in this tutorial video and to your other repair videos as well compared to my ENTIRE 4 YEARS OF COLLEGE due to the rotten & outdated standards of education here in the Philippines. I hope you will soon have a mini-series for Schematic & Boardview-free Voltage/Power Rail Tracing[12V/18-20V Main Voltage Rail, 5V, 3.3V, CPU/GPU Core Voltage Rail, DRAM Voltage Rail, IGPU Voltage Rail, System Agent/Northbridge Voltage Rail, PCH Voltage Rail, BIOS Voltage Rail, Battery Power Rail], Proper method of testing/checking of potentially faulty MOSFETs & ICs/Controller Chips, CPU/GPU/PCH Reballing and BIOS Bin File Editing.

they get chips that do that now? damn! lol

QqCUM chip, 3.3V.

In cases like these, can you ask for the defective board for parts? Straight face please!! 😅🤣

Glad I stayed for the happy ending.

love how you call probing stabbing Graham LOL

Great work

why you do not fix the PCH ? You posted a video at Apr/01 how to do it with a milk 😀😀😀😀😄

I have to pause and walk away 🤣

Professional comment. Nothing about any chip!

I watched a video of you installing the aorus z370. Unfortunately you didn’t go step by step. I know you created this video five years ago.. but perhaps you are willing to help me out with a problem im facing?

I mean it had everything down below happy ending the works

great bloopers

come fly with me .come fly and fly away lol

Motherboard death by Qqorgasm?

Dang the discoloration of that board around the CPU socket is crazy

Very nice

Hope you had a box of tissues handy 😂

I have this latop (if its an i5 1235u) and was wondering if the RAM is upgradable and now I know it is :)

At 5.49 you mentioned "maybe our battery charger or main rain supply depending on what main rail we got"".Please can you clarify "depending on what main rail we got"" because my interpretation is 19 v is the only main rail on laptops. tks

I think that chip had a stain on it

Another interesting video, even though the solution was replace the motherboard.

Qqcum busted all over the pch.😂

Pattern in thermal camera looked like from the back side to me. Did you check the back side?

Just a thought... how common are this kind of failure's? Do u think it has any tng to do with PCH and CPU being on the same chip? If so how concerned should i be coz i got msi modern 15 laptop with the same design... pch and cpu on the same chip. I've had it for a yr and its a nice laptop. With worst possible screen hinge designs...

Are pre surface mount components better or worse quality than surface mount ones?

you are overcomplicating it , there is close to 0 ohm short on power rail , injecting 0.8v can't damage anything , there ain't a thing on this board that's meant for voltages lower than that.

We are professional, we dont talk about a chip on the board. It is not his fault that te laptop is dead.

Be Nice if Your Omh Meter was on The Screen..

please select the language for the windows setup kinda OC with it hahaha

What termo camera are you used?

Normally, when you observe that each component in a device is not identified with alphanumeric characters using indelible ink (commonly white); That is to say, such a device lacks silkscreen printing on each PCB that makes it up, so for that device you will not find the service manual (schematic diagram) either. The majority of recognized manufacturers whose authentic models meet this requirement will be able to enter (be accepted by Quality Control agencies) the demanding North American market (USA and Canada mainly). Another way to say it: I see the PCB silk-screened so I'm likely to find the service manual. NOT screen printed? well... Greetings.

Resp Sir! Very Nice Tutorials. -- ChinnaRao Paderu Visakhapatnam Dist, Andhrapradesh

I don't think he has noticed....

i3 12th gen better than i5 11th gen, surprisingly

Cum on it’s the internet they will always be jokes

I will be an adult and not make a joke about the c*m chip. 😐 I will just laugh instead. 🤣🤣🤣

what on earth has Q been upto on that chip lol

😂😂

Trying to sell an i5 sony laptop on facebook marketplace for 50£(100au$). Nobody wants it. I'm surprised i see so many laptop repair videos still. A dying industry. Bring back Amiga laptop.

OK question how much is a quid

Idk man, im kind of desperate. My computer has been dealing with crashes since the day I built it. I cannot for the life of my figure it out. From SFC scans and repairs, to pouring over Event Viewer and removing software, to scouring windbg for hours reading several dumps. Im at a loss. I have no idea what is causing my crashes. I have tried some other boards with no help. Grasping at straws but if there's any suggestions of anything please help me out. I'll try anything before giving the PC a fresh windows install.

Don't buy HP, kids
