I bought three Lenovo laptops from 2010 to 2011 without proprietary measures on their end. I could upgrade RAM without issue. I gave up on Lenovo this year ever since finding out that they solder one stick of RAM so that if said RAM fails you have to return the system for them to repair it. It also prevents you from upgrading/adding more RAM. I am done with this company and this excellent video supports my stance. Thanks.
@Comrade Of rainbow six seige Yes the older machines were great. The two laps from 2011 are still doing fine one of them being an AMD Turion X2. I do know HP does not solder in their RAM.
@@bocconom Most modern laptops have soldered in ram including HPs it saves space for in 2 in 1 and thin laptops
Lenovo, HP, acer , asus, etc are pretty much the same, when it comes to low/mid end laptops atleast, they are made by the same ODMs like Compal and Quanta.. i saw motherboards from 3 different laptops from asus, lenovo and HP i think it was and they were pretty much identical.. the difference is mostly in the exterior design, screen, keyboard, mousepad etc
just buy apple and shut the fuck up
Yep won't b buyg this brand anymore
If you watch enough TH-cam you will never buy any electronics
Or cars.
hahaha
Yes, it's true.
They will make me design my own damn laptop (which will sure be more than 5kgs and 40mm thick :), but rugged 8-)
THis is the perfect comment. These kind of videos serve a purpose, but still you get the wrong impression, if you rely only on these. A lot of factors, especially factors important to "you" specifically, are ignored. A repairer cannot cover every consumer's need/pov.
I really appreciate seeing your videos. I am not a geek or a technician, but I can see that you are a very serious and honest person. Smart and curious. You are an example of Good Work! Congratulations from Stockholm.
@@andrew_koala2974 What's wrong with you?
Luis rossman: i will never use Apple product
Sorin: i will never use Lenovo laptops
Correct, but Louis Rossmann recommends only the Thinkpads. P-50 very expensive. Get what you pay for.
Thinkpad T/P and maybe E/L is not consumer V/Y/G/Ideapad line. Think about it...
E and L series fall apart I very rarely get p or t series with issues
@@ernestmccollum2397 so Louis only recommends Thinkpads that cost as much as Macbooks that are roughly speced equally. Hmm what does this tell us about the whole Apple hate train?
@@RandomUser2401 It's not just specs that matters. Maintenance and productivity is also a key factor to why people buy Thinkpads.
This is the same thing Louis Rossman was talking about, They sabotage their own computer so you can't repair it.
And force you to buy a new one as soon as possible!!
@@user.fedorman and most people would avoid the brand that just failed, stupid idea If Lenovo done that on purpose
I think Apple takes it a step further and makes the firmware self destruct when read. But Lenovo must not do that if people on eBay are selling them pre-flashed.
@YeshTV this is about us repairing an item that you spent your hard earned money on, where we can fix in a day they want you to pay them and it can take weeks.
@@bazj5392 I know people who have bought Apple laptops which fail, and they go straight out and buy another.
Sorin: "I hope some guys from Lenovo are watching this video..."
Also Sorin: 14:12 - "Hope you guys can see my middle finger alright!"
This guy is just awesome!!
*rants in hidden*
i saw that hahaha
I'm not surprised. I bought a top of the line Lenovo laptop for like $1,500+ and it died a year later. I had taken such good care of my expensive tool and hoped it would last many years, which is why I spent more. I also swore I'd never buy another one. I'm sure failures like this were planned for increase of business. I'd never do this to another person. If anything I give more than I'd get in return on most occasions. I can't support a company that takes advantage of people. Thanks for the video verifying my decision a few years back wasn't by mistake.
Again Sorin, I love watching your videos. You explain everything you are doing, we see no editing cuts. I like how when something stumps you. You take a moment to stop and think about your next step. EXPERIENCE is the BEST teacher. In my last 42 years in the communication industry I do exactly the same thing. No matter who is trying to force me to “ Get it Done “ you have to stop and think it through. Believe me I’ve BURNT up some very EXPENSIVE equipment being force to move it on. You are a GREAT TEACHER Sir. I will continue to learn from you. You are a MASTER of your trade. Thank You very much for all you do and sharing your knowledge . Don’t get a big head now. LOL. Larry :)
What model as of now is good in Lenovo my G50-80 motherboard or keyboard is spoiled they are demanding large amount. Can you suggest best endurable laptop please?
It's because there is only one thing that counts in life now......MOOONNEEEYYYYY! The world is corrupted.

Sorin, I always enjoy your video's your voice is soothing your mannerisms very country polite, your knowledge unquestionable.. Even I, the 67 year old fella that is just below noob and beginner can understand what you are talking about.. I just started to teach myself electronic last winter.. I have quit working on cars and such because my body can't take it any more so I had to do something.. and with all of these cool new project boards and Arduino's, raspberry pi's and such I thought I would try and join the fun.. I thank God I am already loosing my hair so as I pull it out IO only get about 15 hairs in a hand full.. You do not know how much I appreciate all of your video's your style is so conducive to learning for me that it makes it fun.. one day (if I live long enough) I will be able to follow you completely.. in the mean time.. carry on, be safe and enjoy the heck outta life..
Sorin this a criminal action from lenovo, thanks for the info i also will inform my family and friends.
i have a G580 i5 3210m from 2012. It's been running non stop since. Still alive. 0 problems.

@Coolride17 ?
Still using a 2011 lenovo t520, I think they still used the molds and hw designs from the IBM days then, it's very solidly built and hasn't failed me once. But good on you to call Lenovo out on this, I agree this is unacceptable and highly suspicious design. Input protection on pins is a given, there's really no excuse. Either the zener variant you showed or 2 upward facing diodes from gnd to positive. Must be a case of design by gunpoint!
One thing I like about this laptop design is how easy it is to access the CPU fan. One can clean it more often and its easy to replace in case it goes dead or start making a weird noise. In most laptops, you have to remove the motherboard and everything just to access that fan.
Felicitari pentru efortul tau si sustin cele spuse de tine! Si eu sunt in acelasi domeniu si gasesc mereu exemple de design gresit intentionat ( echipamente proiectate sa tina perioada de garantie plus o zi).
Lenovo has many brand lines of their laptops ThinkPads are their higher-end business laptops with their Ideapads being their low-end cheaper consumer brands.
I have exactly the same problem with lenovo carbon X1 1st. gen. i think it´s one of most expensive and have same design. But i have X240 for my self and i really like this one.

Big hello from Romania! Congrats for the channel!
I have old lenovo laptop (cheap and not waterproof). I spilled 3dl of milk all over the keyboard. Few keys stopped working because they clogged, but the computer kept working. It's been working perfectly for 2 years, and when i finally opened it to replace the paste, i saw how it was made. It had a foil in crucial places where it prevented the fluid to go to any crucial parts. I liked that design and I think it is a very good design. Laptop has been working for 7+ years now, no problem. (Lenovo Ideapad 100).
My Lenovo is 8 years old this year, still going strong (albeit running Linux Mint nowadays to keep going)
@@HamzaHanma not really! About an hour. But it was never great!

Thank you for the warning, and mentioning the eBay seller of the ITE chip. I have a dead, no power & no charge, Lenovo Ideapad G50-45, and I was aghast when I heard the 'beep' for the continuity check on the DC-in middle pin and the corresponding pin on its ITE8586E super I/O chip.
Lenovo should do free lifetime repairs for all the affected laptops that have this disgraceful "self destruct" design flaw.
Ten year old Thinkpads rock. I don't know about the cheap non-Thinkpad Lenovos, or new ones in general.

Watching from T530
@@iamlabovic I think that’s the last good model. At least, I wouldnt want a T540 or above. Mine’s a T520 and it just works.
I love the way you solve laptop problems I'd like to lean more from you
Just watch all his movies..
Can you add a resistor and zener diode to the charging port to fix lenovo's bad design?
It's possible, but quite hard to cram these components on such a board. That would not be reliable though.
Of course you can.
Sad, I will make sure to spread these sad news like Sorin so that no one gets scammed like that. Mr. Sorin you have an amazing attitude for repairing and the right to repair. Have a lovely day, greetings from Montreal, Canada!
To be fair, Lenovo has many series of production, the cheap ones and the heavy duty.
I have been using Lenovo X series for more than 12 years now, I have 4 of them in line, and they are all still working perfectly (except for some batteries)
put zener diode should be for all model....zener diode is important...
12 years? That was IBM my friend
IMPORTANT Sorin, the plastic covering the middle pin is broken on you laptop,’s connector, that is the problem.
Watching from my Lenovo, with a recently repaired/reprogrammed BIOS.
Did you reprogram it yourself?
I need to do the same. If you can , please tell the sources you've followed.

Hi
I've found you less than a week ago, and I admit your topics have become even more necessary than oxygen for my life...
Just wanted to express how much appreciated I am.
Keep on, bless you.
Thinkpad, X, and P series are very good laptops. In fact, one of the best on the market as it comes to quality and durability. Saying all lenovo are bad is a bit of an exaggeration. All manufactures are guilty of design failure in their low end products. Cheap, critical design failure, uneconomical to repair, buy new. That's the world we live in and consumer electronics companies business model now days.This laptop is cheap budget lenovo model. This is the case with any budget laptop brand. Apple is even worst, because their high end expensive line is design to fail! You don't want to buy cheapest laptop from any manufacturer. You'er better off buying second hand mid tier model.
Yes, it's nonsense. I have a second hand X230 from about 2012 bought a few years ago for $200 with extra RAM, SSD and added an mSATA. No issues, great keyboard. I also have an X1 Extreme (which was not cheap!) for about a year I use daily for work on the road. Also no issues.
Buy Dell or HP
Stale NFS nah Lenovo and Toshiba are the same crap 😅 but the Dell and HP professional products are great 😬
It wasn't always like that. I still have a G565 in daily use. It was somewhere around 400$ back in 2010-2011 and still works perfectly fine.
@Stale NFS I have an HP from ten years ago and it works great even after spilling crap on it and using it outside in the summer, Results may vary I guess.

Nice video . Very informative. I had a Lenovo laptop the hinges broke in a bad way requiring the whole lid be replaced. Same thing happened with my MSI was able to repair with no parts and still works a year later.
The Thinkpads are different and WAY better.
Please explain!
I plan to buy a used one.
If you search internet you see. Many agree ThinkPad is one of the best laptop out there. I have one myself. Very good design and simply to expand/fix. I replace Keyboard in 2min
And is there any issue with the middle pin?

Thanks for putting this out there 👍🏼
My same model suddenly stop working and unable to turn on and i was told that mother board died so I bought Dell. Now I know what happened to my Lenovo

Well I knew that motherboard was dead
Not just lenevo ,Lenovo learned from Apple non repairable technologies how to make more money making all your products non repairable !
True, Lenovo picked up many bad practices from Apple but their over-large range includes entry-level machines and the G50-80 is one such. It is not a ThinkPad. Although ThinkPad quality has declined since the fad for slimline took hold the buyer should properly evaluate specs, layout and price. A refurbished 'proper' ThinkPad pre the awful mess that was the T440 should last a demanding user many years and can be upgraded. The pseudo-USB shaped connector was inferior to the barrel type from the start and should be discontinued.
People who have pointed out that most Apple products are flimsy and hard to repair despite the enormously inflated prices and lousy official service are right. However, the bad power protection on the G50-80 is on a cheap machine. Sorin might have different thoughts on other Lenovo products but I hope that he has shamed the greedy designers with his cogent points. It is also great to see a true expert at work.
@@stephenhall3515 I could not have put it better
Around 23:10 - putting the magic smoke back into the chip. Thanks for a very educational video, I learned quite a bit including SMT desoldering and use of zener/resistor to protect the pin, though as you point out there should be no need for a consumer to do this and the manufacturer has clearly designed the product to fail.
I had a lenovo android tablet for the home. different family members had different separate user accounts on the same tablet. One day an update deleted the multi account function and wiped all the data from all the non main accounts, no warning no nothing. On top of that LOWERED the resolution of the screen! So the hardware is higher resolution but the software will only run on low!!! And there is no way to return to the original software version.
They do that often , not only lenovo ,but samsung to.They did that on old note 10.1 , which i have...fuck them
My Lenovo never have any issue, but it,s fun to watch your video.
ppl who say " i have a lenovo its its gr8" clearly is missing the point. The point of this video is that if it gets broken, you cannot repair it. And that is anti consumer, and you should not apluaud it.
Just give it a motherboard swap like you do an engine swap on a car.
JTAG interface that can be used for programming of "Super IO" flash memory. We do it on new boards.
i thought these super io are already programmed...thas why for me i tried to replace 1 of the lenovo g50...the board was working perfect but the keyboard was not reading....now have realized that they must be programmed to the same model👍👍
Yeah i think only bios need to program.. but io chip also need..
the board has a 64Mbit bios chip on the other side as well, it's crazy that they split the thing in two places.
I enjoy the slightly older thinkpads durability, like t430 and 420. My t430 has a quad core i7, 2 ssds, 16gb memory.
I have the predecessor, the g50-70.
On it's charging port the sensor- and the +-rail are seperated by a plastic housing.
Looks like they removed it intentionally on later models.
That is how you improve your design!
Does your G50-70 also have this super IO issue?
Maybe they stopped using that style of plug? My 2 year old Lenovo has a old school barrel jack.
This Laptop will Self-Destruct in 20 seconds...mission impossible...Could you have addded Diode Protection..!!!
@@robertoruiz7069 Imagine you drive a car at 20mph and a wheel falls off. Is it the manufacturers fault if the entire cabin falls apart during the ensuing crash? The manufacturer is supposed to build some sturdiness into it's product. Off course you should expect the charging port to get destroyed. The charging port is the third most physically stressed part of the laptop after the keyboard and the hinges (by normal use, I'm not talking smashing screens). CHARGING PORTS WILL GET DESTROYED. Manufacturers know that. If the SuperIO was not protected against the shorting in the charging port SOMEONE INTENTIONALLY DID THAT.
I found your channel after my $1200 Lenovo bit it after only 2 years. Decided after watching a few videos, I wasn't going to be able to fix it, however, watched a video of you working on an ASUS gaming laptop, you pointed out how well it was made, so I picked up a used one. Very happy so far. Lenovo is garbage---I'm only glad that at least my data on the SSD was still recoverable. Great channel, you're a fantastic teacher!
Lenovo quality after 2016 is certainly not the same.
I own many Lenovo laptops(>8) of various models except G50-80, every one of them is very good to excellent. Maybe only the G50-80 model is not well designed other models are very good to excellent. I am typing from one.
Same feeling, my friend's Lenovos and my own t440p never had any similar problem lol
I have a lenovo laptop as well and i can say they are good. Mine is six years old and still going strong. I want to replace it but the damn thing is immortal.
copy pasting my own comment cause the point is still the same.
His point is not giving a fair review, but bashing Lenovo products. I myself had multiple laptops of multiple brands, and those i never had problems with are the asus and the lenovos, unlike the countless problems i got with HPs after just 3 years of usage. Many laptops dont have such design, he's bashing the whole line in name of the fews that do.
Other than that i would never send a repair to this guy, laptop has been handled without care, the whole disassembly was just homeboy stlyle. There's a difference between repairing computers and knowing how to repairing computers.
Thinkpads are great machines but I have experience with a U530 where the hinge cracks (common problem). This forces you to buy a new machine just because some cheaply made part decides to fail.
@@raffaele148 thank you for your comment. This is exactly how I feel. You can't bash the company for an engineering compromise made to one product.
I have been repairing all types electronics for the last 30 years and have 3 lenovo products. I only recommend lenovo of I'm forced to recommend anything.
And it's so true. I wouldn't send my stuff to this guy even though he knows his stuff. He's too heavy-handed and seems to get distracted easily.
Nice video as usual Sorin. I find the quality of Lenovos to be pretty patchy, have used them as corporate laptops for many years. X250 - brilliant laptop, absolutely no problems for 3 years. T470 - complete rubbish, NVME and Motherboard failure within 12 months - along with other random failures. T450 (a little older) - proving quite robust after a year. Replaced T470, random failings again.
Compare that to my Dell XPS M1330.... still going strong with a constant flogging after 12 years - and very upgrade-able. I suspect the complete laptop designs have gone backward in quality, rolling in very poor thermals with gotchas such as this super i/o cooker...
Love my ThinkPad, everyone is entitled to their opinions.
Same! I just commented on my t430 and its mods. lol
The difference between thinkpads and ideapads is huge, though. I had both. My ideapad was a piece of shit, while I love the thinkpad.
Facts are objective, opinions are subjective.
Same for everything, bad practices, scam, exist and have a long life because some people are stupid and even if you teach them the scam point, they stay stupid and live in a kind of deny mind position.
For example, Apple sale expensive hardware and software and spy there customer through back doors, they also lock them with a jail commercial system than they have to buy special plugs, special software for anything, at expensive price. What ever some nice people demonstrate about these crooks practice they do, some customer hate who ? The crooks ? No, they hate the people who show them the objective true about the scam.
Why ? Because they are stupid and yes, crooks make money (a lot) with stupid people. And there is so much...
@@DGDG0000000 , well, at least You are very clever.
I own an oldschool x200 and use some brand-new Thinkpad (from employer). Even though both are thinkpads the difference is night and day. That old x200 with it's Core 2 Duo is still soldiering on despite all odds (with Windows 10 and Visual Studio running... well, at a respectable speed) while the new one is literally falling apart without any reason. So yeah, T series an older W and X are good newer ones not all the time.
Agree with you. That is .. Intended. Why?I clearly understand why buying a product from a company that refuses to protect such a sensitive component like the super IO. Nice video.

Many years ago I worked for HP on their minicomputers.
My guess is that this was NOT an intentional design flaw to frustrate customers. That would take too much thought and work.
Mistakes like this are usually the result of sloppiness, being rushed, not putting a high priority on products being resilient. An engineer might have tried to bring this issue up in a meeting, but be voted down because the schedule was tight.
Kudos to Sorin (and to Rossman) for making knowledgeable criticism of bad design. It is great ammunitiion for engineers inside Lenovo or Apple to tell the rest of the team: "Hey, if we let this sloppy design go by, we'll get roasted online. Let's take a little more time and do it right!"
Stuff like this still shouldn't happen. It is 2 cents in parts and can be done super easily in the schematic and layout. Esd protection should always be there on any pin going outside. This is just a wrong design philosophy / quality standard
@@unbekannternutzer8506 , I don't disagree. I'm just describing how it probably happened, given my experience on projects in a large corporation. The area I worked in was higher end, and people were more careful. Still things like this occurred. There's tremendous pressure to ship product.
Hello , thanks for you input in your videos, i want to ask you, in your experience wich manufacturers are more reliable
first question, is it made by lenovo, or meda for lenovo?
there is big diference
No, it's not the difference as Lenovo is still responsible in front of customers!
Thank you so much i had same exact problem and was almost to buy new motherboard....and i find you...thanks u saved me a lot of money
DELL is guilty of this same practice..... going way back.
i has this same model for more than 9 years and working perfectly
Enjoyed the video. But my work experience suggests this sort of built-in risk is probably mostly an error. From work I found like mistakes in electronics in missiles and radar designs for defense systems. Also errors that can cause total failure. In heavy equipment designed in risks that could result in killing operators. Much design is pushed to meet deadlines that contribute to the risk, particularly as product competition drives decisions, and understanding risk often can be not analysed before failures.
Surprisingly the management of companies do not always acquiesce to fixing these until a history of damage specific to the particular product becomes undeniable even when shown like problems in other products. Caveat emptor cautions that the buyer might over pay, but in these cases the product may cause a catastrophe. Consider the Chenobyl reactor as a particularly extreme example of poor judgement rather than intentional miscredence.
They still continue this kind of design with their laptop motherboards, i have same problem right now, the super io chip of my lenovo y520 is dead and im finding replacement chip, good thing i found your video and knew where can i buy a new one
I will never buy Lenevo after watching this.
Thanks Sorin

Thanks for the heads-up! That continuity tester going off made me cringe! I'll make sure to be more mindful of my charging port (actually watching and typing this on a G50-30, right after a RAM upgrade). I'm also considering adding a Zener+resistor right on the wire. Salutări din Galați!
Lenvo was already on my blacklist for security reasons.
Youri Khan pls explain sir
@@fantasitma chinese
@@executor2056 Then one might as well blacklist every electronics product, since everything is manufactured by Chinese companies...
I can see how bad you feel about Lenovo and the reason you gave out is clearly TRUE.
You are the BEST.
Oh this is HP, different job.
Hahahaha!
Sorin is so funny.
😂
I will get more inspiration from you sorin sir... Thanks for sharing this information your big fan from India
What do u expect from an old laptop , maybe they changed their designs in the new ones
It might be old. But you'd expect it to be designed by an adult. Not a 13 year old.
the board has a 64Mbit [8Mbyte] bios chip on the other side as well, it's crazy that they split the thing in two places.
True IBM Thinkpad only !!!
Omg, esti roman!! Super tare!!! Genial canalul, am invatat multe de la videourile tale! Multumesc pentru ce faci! Tine-o tot asa!
Lenovo is a chinese company with chinese reliability standards for its products.
Sa fii sanatos si fericit Sorine!!!
Who would you say is the BEST laptop manufacturer?
Apple obviously.
Apple, Asus
This video speaks the truth!
I have a second-hand G40 80 and the bios works fine until I decided to reset everything. Now bios has a "system password" required which I dont have any idea about it. It sucks. I hope you guys read this and suggest if theres anything I can do to remove the system Password.

Thanks for all the good efforts my Prof. We are well informed about electronic repairs through your friendly videos. I hope someday you will make us a video on "how to fix Laptop with faulty USB data line". We are condemning many Laptop's motherboard with such problem down here in Nigeria. Please do consider this as a request. Utmost gratitude and God bless.
My Lenovo laptop after 2 years of use: **Random BSoD**
it may have a bad stick of ram.
Noroc cu Karol ca-si sparge creierii cu chestii complicate ! spor si sanatate la toti !

Be careful when you plug in your charger and you'll be ok.
True
@@DariusIC like it's okay ok ?
Not all Lenovo is designed like that. Especially the ThinkPad
@@emanuelmilani7976 I dont have the thinkpad i have a lenovo 300
Great video, it is good to know what you can expect.
Lenovo died when IBM sold it to the Chinese.
Are you taking about Thinkpad? IBM sold it to Lenovo.
@@yuli4708 lol yeah
