I'm not sure how you can make a video about laptop repair simultaneously interesting, relaxing, entertaining and informative, but I hope you don't stop.
Rabbit holes or dead ends make ok videos. Can't tell you how frustrating fix videos are when you've tried them but nothing works. Wins are great but fails teach just as much, at least in the mechanic fields. I always told my troops not to cover up a mechanical error because now I can teach them something else/new. Thanks for the video, always enjoy watching
Sorin: Ok, let's try to flash the BIOS with the new tool
I'm Up for the Rabbit holes and dead ends Videos, for all us newbies and hobbies that's pure gold we will learn and will know that not all repairs are a win. great content thank you.
Given that I've killed my first attempt at a component level repair of a shorted 3.3V rail via liquid damage, I so appreciate videos like this that give me more knowledge and context to what I should look for the next time i try it.
That was an interesting dive, thank you. Successful repairs are great but diagnoses of failures can be both interesting and useful, as this video shows. Think "Hmm... I remember watching Graham diagnosing a fault similar to what I'm seeing and he proved it by doing X, so I'll do that." and "Hmm... I wonder if Graham has had a look at a similar issue? Let me check on UA-cam..."
One thing I hate the most is reading a book only to find out it is missing the last few pages, with that in mind, I enjoyed watching you follow this fault to a logical end, it was educational and interesting. Thank You...
Done watching, thank you very much for the detailed troubleshooting procedure. 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] and BIOS Bin File Editing.

Fascinating as always keep up the good work
Yet another very informative video. Thanks!
I do wonder why the manufacturers don't have any circuit that will sacrifice itself to protect the CPU and GPU. It would probably be far cheaper for the end user as they might not then need a new motherboard
Great watching your videos. I have noticed, when you are looking for shorts using your meter in ohms range, you don’t zero the meter. By shorting the leads and press the REL button will compensate for lead resistance. Sorry if you that already
hey Adam great vid lots of interesting info thank you for sharing
Thank you for explaining things throughly in detail. I had similar scenario
What I find strange is when I do repairs like this it’s not the end, I remove cpu and put another one on. So I don’t see the problem here, only if customer doesn’t want to spend for the work. I mean in a lot of cases the mosfet is at fault, most repairs I do are 70% or more a mosfet problem.
Very entertaining, thank you. 🙂
Sometimes, you get the bear.
Love the channel.
New intro music is growing on me
