If you watch enough KZfaq you will never buy any electronics

Luis rossman: i will never use Apple product Sorin: i will never use Lenovo laptops

This is the same thing Louis Rossman was talking about, They sabotage their own computer so you can't repair it.

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.

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.

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!!

It's because there is only one thing that counts in life now......MOOONNEEEYYYYY! The world is corrupted.

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 :)

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).

Ce surpriza, te urmaresc de atata timp si acum aflu ca esti de-al nostru :)) succes!

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..

Watching this from a Lenovo laptop 😅

Big hello from Romania! Congrats for the channel!

IMPORTANT Sorin, the plastic covering the middle pin is broken on you laptop,’s connector, that is the problem.

The two no like clicks were Lenovo engineers :)

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!

*Which is better?* - Killing electronics hardly by designing traps on ports... - Killing electronics softly by mandatory updates...

Thanks for putting this out there 👍🏼

Sa fii sanatos si fericit Sorine!!!

Plus they lost all my trust with Superfish malware, people seem to have forgotten but I never do.

OMG now i know why.... Thank You Sir!

I love the way you solve laptop problems I'd like to lean more from you

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.

Sorin this a criminal action from lenovo, thanks for the info i also will inform my family and friends.

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.

Omg, esti roman!! Super tare!!! Genial canalul, am invatat multe de la videourile tale! Multumesc pentru ce faci! Tine-o tot asa!

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.

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.

My Lenovo is 8 years old this year, still going strong (albeit running Linux Mint nowadays to keep going)

Hi Sorin, excelente video!

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

Not just lenevo ,Lenovo learned from Apple non repairable technologies how to make more money making all your products non repairable !

Buonasera , la seguo da molto tempo e spero che conosca anche l’italiano. Credo che lei sia un genio in questo settore; guardo anche altri KZfaqrs ma nulla a che fare con lei. 👏 👏 Bravissimo continui così .. 👏 👏

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.

Ma bucur sa vad un Roman care face asta!

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.

good night I would like to thank you for the very useful lessons you have given and important tips you have given, especially in my case repairing laptops, the dislikes you have probably had been given by your competitors, I hope you will continue to teach why laptop breakdowns can be so many and haven't taught everything yet :)

Great video, it is good to know what you can expect.

I will get more inspiration from you sorin sir... Thanks for sharing this information your big fan from India

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.

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.

Thank you so much sir I'm learned lot of from your videos i love your videos. You are doing great job again thank you so much.

hi just seen your Video on the Lenova thank's i just repaired a lenova with the same problem Great :=) all works keep up the good work

The Thinkpads are different and WAY better.

Can you add a resistor and zener diode to the charging port to fix lenovo's bad design?

I bought a Lenovo Yoga in 2014 and it's still very usable today including the touchscreen.

Thank you so much for the info Probably one of the excellent channel on youtube on electronics

Watching from my Lenovo, with a recently repaired/reprogrammed BIOS.

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

Sorin, in primul rand multumesc pentru postari ,le urmaresc cu inters pentru ca am aceasi pasiune ,reparatiile de electronica de orice fel,locuiesc in Spania cu familia de 17 ani si cumpar tot felul de oprtunitati de pe ebay dar pierd mult timp la reparatii electronica si ceasuri.Domul sa te binecuvinteze pe tine si familia ta si tara ta acolo unde locuiesti.

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.

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👍👍

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)

Thank you for this info. Good to know to keep an eye out for this fault. Happy with my Asus laptop 10 years now.

i have a G580 i5 3210m from 2012. It's been running non stop since. Still alive. 0 problems.

Keep it up sir. Support for you from +62 🇮🇩 And what brand in 2019 do you recommend Sir?

Ten year old Thinkpads rock. I don't know about the cheap non-Thinkpad Lenovos, or new ones in general.

JTAG interface that can be used for programming of "Super IO" flash memory. We do it on new boards.

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.

Here's another one: Dell puts a charging clock in the battery. After the warranty is up, it prevents charging. So they don't get caught its based on number of recharges not the calendar.

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!

I have had this same issue with certain HP laptops, KB9020. With programmable super I/O or KBC 19V sent to the chip from damaged charge port.

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!

10 years ago i remember when you hear Lenovo...you know its a durable laptop,i was using bussines model T400 it was really good laptop

DELL is guilty of this same practice..... going way back.

I enjoy the slightly older thinkpads durability, like t430 and 420. My t430 has a quad core i7, 2 ssds, 16gb memory.

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

This Laptop will Self-Destruct in 20 seconds...mission impossible...Could you have addded Diode Protection..!!!

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.

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.

Thanks for the video, I have T460s which works perfect after miner ram and ssd update. But that direct connection makes machine useless in case of lost or destroyed charger. Other misconduct that I’ve noticed on my t460s is soldered ram to the motherboard as they leaved just one additional ddr4 slot for update. Also probably program level disabled second M2 slot, it’s attached to the motherboard but not available in the BIOS .

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.

I love my Lenovo computer and phone and tablet and they all work flawless

Great content , keep it up

Thanks for a great video. Best education

Love my ThinkPad, everyone is entitled to their opinions.

Right, which brands do you recommend please?

Te salut din BUZAU!!!!!!!!!! Multumesc pentru tutorialul la laptop ul acer aspire v3 531!!!!!!!

Great job,i enjoy all what u do.

first question, is it made by lenovo, or meda for lenovo? there is big diference

Oh this is HP, different job. Hahahaha! Sorin is so funny.

thenks for lesson professor

I have Lenovo SL 510 and I have been using it almost daily since November 2009 - over 10 years now. I am writing this from that same model. Never had a problem.

Lenvo was already on my blacklist for security reasons.

I will never buy Lenevo after watching this. Thanks Sorin

Good video Sorin.

Hello , thanks for you input in your videos, i want to ask you, in your experience wich manufacturers are more reliable

What do u expect from an old laptop , maybe they changed their designs in the new ones

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!"

Wonderful demo

Nice job My favorite teacher.it's jour follower Alphani from Burundi un the middle of Africa.

"You can't do it. You just can't do it." (repeat 100 times)

Who would you say is the BEST laptop manufacturer?

Love Your Channel!

Cine ar fi crezut,esti roman din Timisoara.....fantastic.....la ce accent ai, puteam sa jur ca esti vreun rusnac:)))...Foarte tare. M abucur ca am gasit canalul tau. Keep up the good work si salutari din Maramu'.

My Lenovo laptop after 2 years of use: **Random BSoD**

True IBM Thinkpad only !!!

Sorin...I have a Lenovo Laptop Computer and have used it for several years...been a Great Unit. The only Issue is one day Closing the Lid the Right Hinge Broke which in turn Cracked the Touch Screen. I used JB Weld Epoxy to Repair the Hinge and Turned Off the Digitizer Screen in the Setup...still using it!

i have lenovo laptop and im scared after seeing :(
