That sneaky little fella. I love using a thermal camera for electronic repairs. It's also great to show the students when systems are live with fuses and relays showing temperature. Great aid for parasitic drain diagnosis.
@@JonnyFix I just bought a DEPSTECH Dual Lens Endoscope. Awesome piece of equipment. Great having 2 cameras, especially for looking down engine bores. It has a quality recording feature as well. I'm using it more and more & make it a regular tool in my classes.
I think you need to dial down the exposure, it seems a bit bright and washed out, noticed it in a couple of videos now, it depends on the light reflections a bit, maybe set it to auto exposure to see how it performs.
They're definitely available, I'm just a cheap skate. The battery sure lasts 3 times longer than the old camera so I'll pop it on charge between vids. Might need a psu when I launch my hot tub streaming career 🤣
@@Mhndr101 ok. Finally after everything checking I had to change the motherboard. The motherboard i brought from ebay by £140 and £100 for repair cost. I had used local repair shop as lenovo customer service was demanding ridiculous overcharged which that i could buy a new one.
@@Fireheart90 Wuaa i wasn't expecting a reply even this flash. thank you for the info :') guess i have to pay a visit to a lenovo service center in a nearby city. i hope the warranty covers the repair & part changing cost
Love watching you fix stuff, I've learnt lots! Is it just a general rule that random caps like that are 10u 10v? I recently fixed a dell laptop with a similar fault but just left the cap off the board as I didn't know what value it was, working great and still have the laptop so could slap a cap on there. Without a schematic or donor is there a way to tell?
10uF is a good start for main line caps. Once it's working you can measure the voltage at that point to know what rated cap to put in there, physical size plays a part as well. If say a 20V line you wouldn't put a 20V cap, you'd use say 36V. A 5V line would be better off with a 10V one instead of 6V. Often as you know it makes no difference leaving it off. If you had to remove 2 bad caps on same line then yes replace them. Only time you might notice it is if a cpu, ram or gpu line and the machine is running at 100% like in gaming it might show as random crashing or image glitching but that would be an extreme case. But on the general 5V or 3V line they aren't as critical in my opinion. Thanks for watching!
@@JonnyFix Some good points regarding what voltage rating to use, noted! Feel a bit silly I didn't think to measure the line after to see what voltage it was, next time I'll do that, thanks for the info :)
Well done :-D Bloody capacitors!, they seem to be failing way too often. I'm starting to wonder if its done on purpose. I've got a few ancient machines that never fail, better parts or just luck? Mosfets going poof is a really common problem in some brands (under rated ?).
It's funny how the older stuff almost never dies. Maybe as time moved on and things became more competitive the parts supply went to the lowest bidder and rated claims became a bit of a stretch.
@@JonnyFix Yes that makes sense, The crap, sorry cap :) is eather under rated for voltage so there is an internal arc that welds the structure, or the layers are so fragile that vibration or temprature changes cracks the internal layers. I almost sound like i know something ha ha :-D
@@JonnyFix i learnt a lesson a long time ago, dont be a big head, there is always someone around the next corner that can make you look thick. So run away from that corner ha ha :-D
Element14 but also mouser, digikey, rs components. I'm sure you could find them on ali/ebay if you don't care for quality but I'm sure they're just fine.
first thing first you should have check for power voltage charger , i am no expert but you went straight to the M.B , at the end of the day you fix it but you took the long way
First things first I did check the charger. The simple act of passing it through a USB meter at 0:37 shows it was supplying 20V to the laptop. When you have experience you don't need to shove meter leads in the end of charge cables just to prove a point. I went straight to the motherboard and as you see the fault was on the motherboard so spending more time checking the charger would have been a waste.

I keep forgetting I can record thermal image video on my phone so I don't need to point the camera at the phone. Maybe next time lol!

Good job finding that shorted cap. Nicely done!
Cheers mate!

Yeah I did wind it up a bit
Amazing detective work! Well done
Thanks! Appreciate the comment :)
You should try and find an AC supply for the camera, that is what I use so I don’t have to constantly charge batteries.
They're definitely available, I'm just a cheap skate. The battery sure lasts 3 times longer than the old camera so I'll pop it on charge between vids. Might need a psu when I launch my hot tub streaming career 🤣
What's the device that measures current draw at 0:34? Looks neat
A USB power meter. There are many different types under that generic name with different USB type sockets
Hi, thanks for the video. I have yoga slim 7 and same problem. Do you have any repair centre? I love in Manchester.
Ugh I have the same model with the same problem that just occurred last night and I left with nothing to do :(

and I came here thinking I could fix my own laptop 😥 Appreciate the video though.
Why would you not charge for this repair??
AAhhhahaha.........haha,......ha......ha...... 😊

Corporate computing does not care about fixing. They just replace and send this back to the maker.
Where did you get the parts
