No you didn't! :D

I'll pay that.

Thanks. That will be one thumb up, please.

Dave, Have you moved to the new lab building?

Only a fool would ask that.

Yeah, it's crazy. I was on Skype call with my best friend after my laptop's charging circuit died and they said something like "oh, about time to get a new one then". And I was shocked! Hell no, I'm going to rip this thing apart and see what's going wrong. Turns out a MOSFET was blown and I had a replacement part, and it only took an hour or so to get a new one in.

An hour of someone's time for component level repair is worth anything from $100 to $300. Older laptops or cheaper laptops would be easily totaled at that rate.

people throw out lcd monitors all the time because of 20 cent capacitors. back in the day you could find crt tvs and monitors on curbs for bad transistors, those only cost a buck or two a well.

First you pay someone to diagnose the problem (base pay + benefits + social security + Medicare + Federal Unemployment taxes + State Unemployment taxes + Workers Comp +++ etc.). Then you pay someone to fix it (see above). Assuming it can be fixed. And at the end you have a used piece of equipment that YOU have to warranty for when the next item fails (because the owner will never believe you did not break the component on a completely different board/area while working on it). Economics do not really support the effort UNLESS you are a small company (or single individual) doing the work. Or you can charge a lot for the work, such as repairing really high-end or rare pieces of equipment. Sad statement on economics. Taxed to purgatory then further litigated into oblivion.

***** I would honestly be shocked if you charged me $10-$20 an hour to repair a modern laptop, but to each his own I suppose.

That's a good idea, he could auction it as a prize or something ... I'm sure someone out of 350k people would be interested in having a genuine, as-seen-on-youtube, fixed-by-dave item!

Personally repaired by Dave? That is not refurbished, that is "made perfect..." or "quality assurance by Dave's own hands." It's like those flags that have "flown over the White House", they run them up, count to ten, take them down and bag them up. Market as "Used by Dave himself." or "Checked for accuracy..." or "Tested by Dave himself." It should be worth at least a 2X premium. 3:-)

How'd it go?

+EEVblog I was young and I didn't stick to the pt properly. No pain but no full extension. I'm missing probably 3-8 degrees to full extension of the knee.

I thought that about Dave repairing the item on film. But then in most situations a sane person within this industry accepts sods law, like Dave admitted. It's just the way it is. It's also interesting to observe those who will not take responsibility or criticism and see it as a sign of weakness or what have you and do what they can to shun similar. Some people are glass half empty and some are glass half full with life's choices.

That would do it, yet, the physical therapy is very important.

It's a jiggled model

Good point.

agree, that failed inductor is pretty darn close to the input jack...physical stress might be a contributing factor.

But did you knee eventually fully recover enough to play sport etc?

+EEVblog I'd say yes considering my situation. ACL and Meniscus are the common sort knee injuries. But being Type 1 diabetic w/ compromised immune system slowed down recovery. Just started rehab later then expected from swelling taking longer to go down, but once it did it was full speed ahead. Unfortunate I also had torn the Meniscus and because I had to fight insurance for two years for surgery approval it became beyond repair. So that bothers me, but ACL is good. I have a knee replacement approved, but don't want that until I feel it's the last option. Key things are get it done as soon as possible, use a good sport surgeon that has done many of them.Don't slack off on rehab! My shoulder recovered better then original, but I was rigorous with rehabilitation. Everyone will tell you take rehab serious to build it back up and it should be fine, I know people that were lazy with rehab and years later regret it. Good luck, I'm sure you won't slack off with rehab and should be fine.

You're not alone!

lol even though I have almost zero electronics skill compared to this guy, I always hope the same thing. Hoping for some leaking caps, brown spots etc.

Look back on the channel about a year or so, and you'll see Dave's all-but given up on repairs because these days it's always something complicated.

I have a repair shop for mostly SMD components, and it's 90% cracked solder joints or component solder joints just like this. My microscope is my friend. Then mechanical parts like pots, switches, then transistors.

In case of such warranty claims right after using the product for the first time, it's very often a faulty component or some mechanical problem that happened during the production (bad connection or even a connector that lies around). The things will be different if one fixes only things that worked fine until now.

I was thinking that also, based on that pillar and the isolation gap, there could be more torque on those components than expected. I suggest taking another look at the other inductor, it looked to me like it might be cracked also.

Interesting observation, I'll take a look at that.

See Joe Smith review of the BM 235. He found the factory fix.

It is around 7:40 in that video.

You are right. See the 7:09 mark: kzfaq.info/get/bejne/nZmljMZ5ptvRmHU.html

Airplane cargo holds don't get down to -50°C. They have a single pressure vessel that contains crew, passenger and cargo areas. The whole vessel is pressurized, and therefore receives conditioned air. In some planes, the under-floor cargo area is sealed for fire protection and has its temperature loosely controlled by a surrounding air jacket, but none are open to external atmosphere.

Yep, more likely cooked in the back of a tractor-trailer or truck instead while being shipped.

Yep, I once had to leave a trailer full of Post Raisin Bran at the rest area in the Virgin River Gorge for a week while waiting on a part. 100 degrees + every day. Don't know how hot it got inside that trailer sitting in the parking lot.

I think those pads look awfully big for those components, when you make solder strech this far, it's prone to crack under mechanical tension. Solder ain't flexible.

Troll alert! inconsequential...

EEVblog Not really, maybe inconsequential is a bit harsh though. I am only expressing an opinion, I personally can't see what the fuss is about, I don't really do obsessive.

Now that's what you call a Braindump :-)

My money would be on a thermal stress failure during soldering.

Agree

But we dont know how much didnt passed at fab. It could be 50 failed for 1000 pcs.

Arek R. I don't really mean just this device. I'm thinking more any given device has hundreds if not thousands of components with that many points of failure if not multiple ones for each component. Then think of how many devices you have in your daily life. Its amazing that stuff isn't exploding left and right.

Think of computer motherboards, or ever server boards like that 8 PCI-E slot one on LinusTechTips. There's some ridiculous number of components with miniscule pin pitch and several layers in the board. But then also think about the cheap Chinese crap that just about works through its usable life and is planned to be obsolete.

Computer/server mobos have up to 16 layers PCBs...

the movs would have saved it before it could think about its family

In that case I think it's more likely it had a weakness to begin with.

That's not a good advice. If surgery is necessary he needs to take it. No offence, but you're not a doctor and ACL can have complications if not treated right. It's just about the stupidest advice you can give.

aserta Im saying skip the surgery if thats an option. as in the doctor says "get surgery of do these exercises for n months." So many people (americans at least) jump to surgery and don't even ask if there is a plan B.

You can get by fine without ACL surgery if you live a fairly sedentary lifestyle, and maybe just run or cycle for exercise or something. But anything else requiring any sort of twisting action will be out the question. eg. playing with kids, outdoor stuff, etc. I did this injury 7 month ago, and I've popped my knee even in the kitchen just pivoting around.

I'm speaking to the surgeon tomorrow. But I already know it's entirely optional. I could win the tour de france or an ultra marathon with no ACL. But play ball with my kids in the backyard, probably not very well.

good luck with it then :)
