I got it but it it was faulty, but it was repaired for warranty for same price. It took like two weeks more to get back, but in the end got quite handy device for like 1/5 of normal price. Phone itself isn't special, but thermal camera with normal camera overlay is very good for mobile device. I highly suggest to keep eyes opened for such shops and deals.

These mid 2010's Lenovo's are workhorses. I have a T430S and 2 T440p. The T440p I am on right now has been upgraded with a 1080P IPS panel, 16GB DDR4 RAM, a 4 core/8 thread CPU (i7-4910MQ CPU @ 2.90GHz), a total of 2.5TB of storage via a DVD-ROM replacement with a 1 TB SSD, a 500GB SATA m.2 2242 SSD and a 1 TB SSD in the normal location. There is only one more upgrade I'd like to do and it's the touchpad. You can put as t450 pad in place of the t440 one. I was told the T450 does not have a drop in replacement for the CPU so I didn't want to be bothered with it.
Yeah, I also use Lenovo since a long time. My day to day notebook is still an X230. It's old, but very well made and does all I need. I could switch to the T450S from this video, but I don't see the point. For power usage I have a powerful desktop and notebook is just for simple tasks and if the battery is still alright, the performance doesn't matter much. On the T450S as I said in the video I keep a windows installation for testing purpose.
@@necro_ware My T440p has a Windows install, and on the other drive is Bataocera for retro emulation. I still haven't put anything on the 500GB drive, but I may put Linux on it.
My daily laptop is a T440p with an i7-4800MQ, 16GB DDR3, GT 730M, 2TB Crucial MX500, 1080p IPS, 100Wh battery, DVD-RW, fingerprint sensor, backlit keyboard etc. It does also still have a 3G modem but that's a bit useless now. I have Windows 10 and Xubuntu 22.04 on it in dual boot
After repairing main power line, on lenovo laptops always check first two mosfets on the input, near power connector. In 90% of cases, the first or second mosfet is also shorted because of previous short of main power line. And why is it important? They are directly connected to charger circuit which detects if you have charger plugged in, decides how high current it should drive to battery, and also decides how and when to switch from battery power source to ac adapter power source, or even dock power source. These two mosfets on the input are very important as you can see, and they can be checked separately because if they are shorted you cannot detect it directly, measuring main power line resistance referenced to ground, but instead by checking resistance or voltage drop between drain/source/gate. Another interesting point - if first mosfet is shorted = charger would switch to protected mode, if the second one is shorted = charged would not switch to protected mode, but laptop would be dead like in main power line short :)
You can hardly tell there's a repair, great job. I wish I could still do SMD work without it being crooked or flying across the room. Definitely mount that camera to a rig, should make scanning close for hotspots easier.
I've had something like this happen to me. I had a laptop where one of the filter capacitors for the video card had shorted out (very similar to what happened to you). I followed the short to three capacitors in parallel (just like you had). I decided to remove all three capacitors and measure them out of circuit and one was bad. The other two capacitors had different values (I think it was 1 uf and 47 uf) and I couldn't be certain what the third value was or its voltage. I put the two good capacitors back and reinstalled the video card (the laptop had two options for video. A built in 2d accelerated and an add on 3d accelerated card). I powered up the laptop and measured the voltage across the two capacitors. I then ordered the largest value capacitor that had the same footprint but at least a few volts more than I measured. When you have multiple capacitors in parallel it's fine to power up the machine with one missing capacitor. I wouldn't consider it fixed, but at least you can check voltages.
On main power rail you can just ignore one cap. Device will work fine. Output caps of other PSU's (3.3, 5, 1.x...) on board is something else but main rail have resistance so low that other caps will do the job just fine.
Oh, hey, it's my laptop! Was bummed I couldn't put an NVMe drive in it, but with a couple new batteries and some fresh thermal interface, she's still my daily driver. I got it for free because it had a busted screen maybe six years ago. It's amazing how valuable being willing to repair stuff can be.
I only recently bought a thermal camera, convinced by everybody on youtube, but somehow I still have more trust now my milliohm-meter… yep, for finding hotspots where I might need more heatsinking I do appreciate the thermal camera, but for finding shorted caps/tracks I always fall back to my milli-ohm meter… but then I am old, and can still remember those old days of voltage injection, with lots of current to blow up a solder-bridge underneath a SMD component…. And yeah, seeing juniors techs/engineers frying the whole PCB with voltage-injection… guess I am just old and over-cautious, lol…. I know, I know…. Lower voltage that what is required to switch on semiconductors, and not enough current to burn tracks, and then use the thermal camera…. At least with the milli-ohm meter, I cannot burn tracks… and when that doesn’t work, then I *might* revert to the current injection method, but I haven’t short that the milli-ohm meter couldnt detect. Yeah, Yeah, I know…. With current-injection and a thermal camera you don’t have to measure so much, you just inject current somewhere and the shorted area shows brightly…. Sheez…. I am old, OK, still slowly building in thermal cameras… even though like in 20 years ago, when they were very expensive, I tried convincing management at my old company to buy a very expensive one to verify designs and look for hot components, that was denied…. Guess I was just a bit ahead of my time, but now everybody seems to have overtaken me…😂😂😂😂 guess technology moves quicker when you get older…
Nice. I was only like 5mins in vid and was saying myself here that thermal camera might do wonders. My S62 Pro has quite nice feature for overlaying camera picture with thermal image. Now this all being said I just remembered that I have one dead laptop (quite good specced one, well it was back then) in storage for years that doesn't power on and I didn't have that IR phone when it died. I'm definitely going to check it out some day if I might find something in it.
we were taking these out of service already 2 years ago at my old job. They weren't aging particularly well, the batteries in the 50 and 60 years are really prone to swelling by now.
Thanks for checking the linux and open source support in that camera. That means I might actually be able to use it. I don't need one right now, though.
Yes, that's possible too, you just need a high precision multimeter. But that is a very unreliable way, especially on tightly populated double sided SMD boards. On an old 386 this works fine however.
@@necro_ware I have very nice and chip AN870 with 1999 counts, it can measure 0.001 mV. Then repair ASIC PSU, found short transistor placed in line of them :) In motherboard and GPU it's much easy, because it have inductor :)
I used my Chinese thermal camera to find a shorted capacitor in my daughter’s phone. She dropped it in the lake and it took on water. I’ve used it at with too to find shorts on boards. Really great tools and the prices are coming way down.
My Flir C5 thermal camera has the same pause during calibration, and I've seen it on much more expensive models too, so this is at least on par with other cameras and I wouldn't hold it against it. 😊
That's interesting. I also bought a TC001 and wound up finding the same issue on a handheld device, a shorted 0603 cap. What's strange is your TC001 has that external lens and you have those issues with focus. Mine does not have any lens and it auto focuses. Not sure what that lens is actually for, mine can focus clean across a room or fairly close to a PCB. Some cameras have removeable macro lenses but they are for getting really close. My TC001 does not have a lens mount but there are 3D printable lens holder models out there.
It's probably possible to calibrate it manually in the settings. I have a old CAT phone with thermal imaging and this option works. And in black and white mode it works the fastest
I'm a thinkpad man, and I usually leave those rubber stoppers out when I reassemble a system. They don't really do anything except keep you from pushing that keyboard screw cover off.
I just want to tell someone that I destroyed a power board for a computer monitor today because I absentmindedly put it on a **metal surface** before plugging it in to test it. It was probably toast and I had to spend 30bux for a replacement, but it was incredibly embarrassing 😂

Did you check the voltage on that power rail? Cause it would be funny if it was 19V rail, but the donor cap you replaced it with was from a lower voltage rail (e.g. motherboard vrm) and may not be rated for such voltage.
One thing I notice on newer laptops (especially the non removable batteries) they no longer have that small button battery for timekeeping, but relied on main battery for that. Is that the reason why your lenovo laptop got two batteries?
This notebook has CMOS batterie, you can see it in the bottom right corner. So far I didn't see any devices without that battery, but I usually also don't repair notebooks very often :) This one is probably the newest, which I ever opened.
Wait, a Linux nerd with a wife??? Never thought I'd see that 🙂 Also, Lenovo have something called "hardware maintenance manuals" for all their hardware. In those you can see what exact steps to take to disassemble/assemble everything Lenovo.
yeah unfortunately, I had some devices that require app, never again, I prefer to buy the ones that are standalone, even tho they are more costly. My flir with lightning depends on a working iPhone, their USBC they told me only androids... support told me to get a $800 Bluetooth one! not the best option.
Don’t watch UA-cam to see how other people broke open the laptop, be smart and use the service manual freely distributed to Lenovo account holders to open it properly, here you will find instructions on disconnecting the internal battery from bios (should you still have access).
That's true, better always to double check if the resource is trustworthy. That's why I often repeat, that nobody should ever consider my channel professional tutorial. Just a hobby of a software engineer, which nobody should rely on :)
but why wouldnt they just cover the metal case of the laptop in a piece of insulating foil lol instead of this patchwork of ill-fitting scraps of insulating foil on each component they could have achieved better results, without appearing so unprofessional also, i would love to find a thermal camera that could output an image in a standard format.
The question is, what is meant by "standard format". As you saw in the video, the output stream is a standard video device, which you can access with any video capture software. The additional temperature information has to be extracted separately, but I don't think, there is a standard for that. To be fair the extraction is very straightforward and is already open source.
@@necro_ware yep the open source extraction software does add a lot. it's still not really what im looking for. id like to be able to just hook a display up to the camera without the need for external processing.
Android trick: In application properties you can turn off network access per app. So even though the app has access to some information, it has no network access to send it anywhere. Can also help block ads in games if you don't have root or Adblock.
В Германии в основном используется слово Notebook. Laptop почти никто не говорит. Раньше считалось, что Laptop имеет дисплей минимум 15" или больше, а Notebook меньше. Потому слово Laptop устарело и сегодня практически не используется. В других странах может быть по другому.
@necro_ware Nice sound effect from Predator! :D Great video as always @necro_ware I myself would love one of these cameras, but sadly out of my price range right now. Some day I might be able to get one. One of the tricks I try to use is looking at the resistance of the short. The closer to the short I am I find the lower the resistance. At least gets me closer to the area where the short is anyway.
This is why I love repairing hardware. Even though this laptop was completely dead, 99.9999% of it was still in perfect condition. The challenge is to find the 0.0001 that isn't. Awesome video.

The question is, what is meant by "standard format". As you saw in the video, the output stream is a standard video device, which you can access with any video capture software. The additional temperature information has to be extracted separately, but I don't think, there is a standard for that. To be fair the extraction is very straightforward and is already open source.
@@necro_ware yep the open source extraction software does add a lot. it's still not really what im looking for. id like to be able to just hook a display up to the camera without the need for external processing.
12:16 - You used your shaky hand for the first time? Did you do everything else one handed until now?
So far I always used just my feet. I needed both hands to hold the camera ;)
Android trick: In application properties you can turn off network access per app. So even though the app has access to some information, it has no network access to send it anywhere. Can also help block ads in games if you don't have root or Adblock.

Очень странно, что автор видео, говорит слово " Ноутбук " Очень чисто на русском 😊 иностранцы не используют это слово, они говорят Лэптоп!
В Германии в основном используется слово Notebook. Laptop почти никто не говорит. Раньше считалось, что Laptop имеет дисплей минимум 15" или больше, а Notebook меньше. Потому слово Laptop устарело и сегодня практически не используется. В других странах может быть по другому.

Nice sound effect from Predator! :D
Great video as always @necro_ware
I myself would love one of these cameras, but sadly out of my price range right now. Some day I might be able to get one.
One of the tricks I try to use is looking at the resistance of the short. The closer to the short I am I find the lower the resistance. At least gets me closer to the area where the short is anyway.
