There are several methods to resolve, but here are the almost BEST TWO SOLUTIONS: A. 1. Turn off the laptop, unplug the power charger 2. Press the Fn + V + S keys at the same time and keep pressed for 40 seconds 3. Press and hold the power button for 40 seconds 4. Then turn on your laptop. B. 1. When you are in Windows, close all your open programs and windows 2. Force shutdown your laptop by holding the power for 4-6 seconds (pay attention that this method can bust your windows instalation)
Can you please explain why the option A helps whatsoever? I'm really curious what exactly this fn + s + v shortcut have done to the system while being shut down, alongside with 40s power button hold after that. It's mind-blowing it actually works. Big thanks!!!
If your keyboard doesn't work at all, even in the bios, do the following: 1) Turn off the laptop, unplug the charger, 2) Press the Fn + S + V keys at the same time for 40 seconds. 3) Then press and hold the power button for 40 seconds. 4) Then turn on your laptop.
Dear friend I must say this worked for my y540 17 inch, 3 times so far. BIG THANKS. I have this problem with newest 45 version of BIOS. Formatting disk didnt help. Unplugging charging cable, switching off and pressing keys doesnt do anything as resetting via NovoButton works (so battery didnt drain). So I guess its just about unplugging power and starting without charging cable. Maybe with battery disconnected this would work, need to check, someday.
Bro i don’t have words enough to say but u are incredible man🤦🏻♂️❤️❤️i just tried it again and guess what it workssssss🔥🔥🔥🔥i have been searching for a solution for 2years and finally i found it so thx for your help bro ❤
One thing that works all the time is to force shutdown your laptop by holding the power for 10s, then press it again to turn on and the keyboard works. But after a reboot the keyboard dies again and doesn't work till next force shutdown. Very shitty situation and lenovo doesn't give af.
From what others have surmised. The issue lies with the built in keyboard controller on the motherboard. I purchased a used y540-15 and was not told of its issues. Needless to say I taken royally on the deal. Keyboard work once out of ten boots. Screen is scratched severely, and there is an puncture mark in it and then TouchPad... It is weird. For me, when the keyboard decides to quit, the fn functions all work fine still. Even with the USB device descriptor error present... But when the keyboard does its not working thing. I just hold the power button for 30 seconds, and it usually comes back to life. Needless to say, I had a chat with support, and I am purchasing the mid tier warranty extension. They will check it out for me. Hopefully.
Thanks for this solution that worked for me. Another case is accidentally activating a keyboard lock feature. In this case try pressing the Fn and Esc keys together to turn off the function lock. I did it accidentally and this method worked for me too on a Lenovo Legion.
If you shut down the computer, unplug the power adapter from the back, power on the computer, the keyboard should work again. Repeat this every time the keyboard stops working.
@@rollin-troll of course it's a design flaw... For a permanent solution, see below, i pinned a comment where i explain some methods to resolve issue(one is also this, said by you in first comment). You can try and maybe it suits you. Saddly, i don't have an 100% working solution.
well dear friend , i read someone had this problem , the same . but it was still under warranty , and they changed his whole motherboard . so seems like there is something sketchy about the build process . over all , let say this , if only keyboard is going to die and the laptop is going to work just fine for another 5-10 years , screw this . for me personaly i can live with external keyboard .
i kind of don't think is keyboard; because on a lot of people, problems ocurr when notebook is updating bios, throgh windows 10 updates; even you say exactly the opposite "they changed the mainboard" NOT the keyboard; but is very low business from lenovo this aproach, to left us with eyes in the sun...
what i've found to work is to place a robber to push on the keyboard connector latch, i've stuck a robber on the latch high enough to press on it when the ssd is mounted and it worked. this was done after i've replaced a new keyboard on my y7000-2019 and i've noticed that the keyboard worked intermediate, sometimes worked before boot, and i was able to pick options to install the windows, but once in installer didn't worked. also fn+F keys functions worked with no problem. my guess is that the poor design of the connector sitting under ssd get warm from ssd and deform in time and doesn't make good contact with the flex keyboard cable perhaps this will help somebody to not spend 5h to fix this crap
I have an Unknown USB driver in my Driver Manager that can’t be identified. It’s linked to this problem with keyboard somehow and it can’t be deleted (just reinstalls right away). The keyboard doesn’t work even while booting with it being unplugged. It works in Bios and the FN keys work all the time. It’s impossible to fix I guess?

Salut, ai reusit cumva sa rezolvi problema intre timp? Numai ce am intampinat si eu aceeasi problem, la fel ca si @Cross dupa update la windows 11. Timp de 3 ani nu am intampinat problema, cei drept laptopul a fost folosit cu tastatura externa in ultimul an jumatate. Sunt mai mult ca sigur ca e de la updateul de windows 11, am citit tot ce se putea gasi pe net si la fel ca si tine am incercat absolut tot ce era posibil inafara de schimbul placii de baza care nu se renteaza pt un Y7000 din 2019. Multa lume spune ca ultimul keyboard firmware v43 e cel stabil care merge si cineva la care i-a fost inlocuit motherboardul de cei de la lenovo spune ca noul motherboard a venit cu bios v36 si keyboard v43 si nu a avut probleme. Firmwareul v43 nu e de gasit nicaieri, singurul fix la care ma pot gandi e un windows 10 pe care probabil il voi incerca...
Update: Win10 nu a rezolvat nimic dar pe Win11 nu imi aparea nici macar updateul pt y540 firmware. Pe win 10 am primit notificare si am reusit sa il si downloadez incat sa ii pot da install manual. Mai incerc niste ghiduri gasite pe net si updatez
@@alexcaus nu, nu am gasit rezolvare; bine, nici nu mi-a mai venit vreunul la depanat cu problema asta; se mai pot incerca niste chestii, dar sunt sanse sa stric de tot placa de baza; win10 nu rezolva nimic, nu prea poti rezolva cu nici o varianta. Citeste comentariile pe care le-au lasat ceilalti la postare asta, cateodata singura solutie e cum a zis un tip mai sus/jos, cu o anumita secventa la pornire referitor la pus sau nu incarcatorul in laptop; cel mai bine, nu mai pierde timpul, foloseste-l cu tast externa si aia e.
The keyboard failure is due to the malfunctioning of the control chip, it’s common problem for Lenovo laptops as I searched on the web. The only solution is to replace the keyboard control chip on the mainboard, but I can’t find people who can do this in Canada. The chip is just $5 but you need someone to do the job.

Salut Daniele as avea si eu doua întrebări am același laptop merge cat merge apoi se închide ecranul gen sleep mode…tastatura nu mergea tot ca si la tine, ce spui ce as putea face ca nu merge deloc merge cat merge apoi intra in sleep am făcut setările sa nu intre in sleep dar tot intra ori își dă restart am reinstalat windowsul dar tot degeaba ce sugestii ai avea? Aștept răspunsul tau te salut :)
Salut. Referitor la tastatura, citește primul meu comentariu, este fixat de mine, fă ca acolo și dacă ai noroc, îți va refunctiona tastatura. Cu problema a doua, referitor la sleep/restart, e mai complexa chestiunea. Trebuie detectat din ce motiv face și apoi rezolvat. As începe, dacă te pricepi bine, cu curățarea perfecta a sistemului de răcire (radiatoare și ventilatoare), pus pastă termică Arctic mx-4 bit.ly/Pasta-termoconductoare-Arctic-MX-4 Și, făcut update bios. Cam astea ar fi. Trebuie sa ții cont ca este un laptop destul de vechi și sigur s-a jucat pe el mult și poate nu în condiții ok. Apropo, e al tău de nou?
Saluare,eu as vrea sa stiu daca imi poti spune cum sa o dezacivez tastatura de la un acelsi pc,pt ca vreau sa pun o alta tastatura peste cea de la leptop si vreau sa o dezactivez ca sa nu se apese butoanele de la tastatura pc-ului cu cea externa care o voi pune peste.Imi poti face un tuto sau explica etapele te rog.?.Mersi

@@DaneluRepairs Din Iasi. Ohh, la mine s-a bulit din momentul in care am pus o tastatura externa la laptop. Ceea ce este ciudat e ca problema nu a aparut pana ce nu am facut update la windows 11. Pe windows 10 mi-a mers fara probleme chiar si utilizand aceeasi tastaura externa. Am incercat mai tot ceea ce era pe youtube, am ramas fara optiuni. Ma gandesc sa reinstalez windows-ul, dar nu cred ca va ajuta cu mare lucru asta.
@@TheVonCross pacat; nu are legatura cu windowsul sau cu faptul ca ai utilizat o tastatura externa; are legatura cu faptul ca windowsul a facut update de drivere si acum si 10 si 11 e in stare sa faca update si de bios; din momentul in care s-a facut update de bios, adio tastatura; nu mai stiu exact versiunea de bios cu probleme, dar de la ea incolo, nu mai ai ce face; daca te-ai uitat la video, eu i-am facut chiar si downgrade de bios si degeaba. Dar 100% asta s-a intamplat, cu update de bios facut de windows; oricum cei de la lenovo sunt foarte ....insert epitete... la faza asta, nu mai zic ca nici nu vorbim de vreo janghina de laptop, in ideea sa nu-ti para rau prea mult de el. Cand voi mai prinde vreun model de genul asta, si sa nu imi fie teama de repercusiuni, ca se poate si strica de tot laptopul, o sa mai studiez problema, ar mai fi ceva chestii de incercat; deocamadata, la acesta clientul a fost multumit ca i l-am facit sa porneasca si sa il poata folosi chiar si cu o tast externa, ca el il stricase de tot.
@@DaneluRepairs Da. Este destul de aiurea. Acum nu stiu daca este legat de Bios, deoarece prima data cand mi-a facut asta a fost imediat dupa ce am conectat tastatura pe noul win 11. Am facut un power off, power on cu tastatura externa scoasa si mi-a functionat din nou tastatura. Dupa aceea, a doua oara cand am conectat iar tastatura externa am avut un comportament ciudat, abia dupa a 4-a runda de conectare, tastatura laptopului a devenit inactiva. Cu toate ca HW este functionala, pot aprinde lumina de backlight cu 2 taste, iar touchpad-ul este functional. Ma gandesc sa nu fi fost un conflict in momentul in care win 11 a incercat sa instaleze driverul de tastatura. Este doar o presupunere.
@@TheVonCross uită-te la clip, sa vezi câte am încercat eu. Degeaba. Și sunt 99% sigur ca e din bios. Poți cauta si pe net, sunt foarte multi fix cu aceeași problema. Și pe reditt sunt mulți.

Update: Win10 nu a rezolvat nimic dar pe Win11 nu imi aparea nici macar updateul pt y540 firmware. Pe win 10 am primit notificare si am reusit sa il si downloadez incat sa ii pot da install manual. Mai incerc niste ghiduri gasite pe net si updatez
@@alexcaus nu, nu am gasit rezolvare; bine, nici nu mi-a mai venit vreunul la depanat cu problema asta; se mai pot incerca niste chestii, dar sunt sanse sa stric de tot placa de baza; win10 nu rezolva nimic, nu prea poti rezolva cu nici o varianta. Citeste comentariile pe care le-au lasat ceilalti la postare asta, cateodata singura solutie e cum a zis un tip mai sus/jos, cu o anumita secventa la pornire referitor la pus sau nu incarcatorul in laptop; cel mai bine, nu mai pierde timpul, foloseste-l cu tast externa si aia e.
The keyboard failure is due to the malfunctioning of the control chip, it’s common problem for Lenovo laptops as I searched on the web. The only solution is to replace the keyboard control chip on the mainboard, but I can’t find people who can do this in Canada. The chip is just $5 but you need someone to do the job.
It's not that simple.
Problem is not the chip, is the software inside.
I pinn the best two solution in comments, read and do.
I did and it didnt work, and trust me, the chip replace will solve the problem once for all.

Having the same issue? Did you find a way to solve it?
No
hello ,did you resolve the problem? I have been trying for few days to resolve my keyboard problem.i tried everything.i could found on the internet. The problem is my half keyboard keys work and when i start after long time the laptop the keyboard works almost normally but after some time the same keys die again. Do you have any tips about my problem?
i don't have a permanent solution; but, you can also read all comments on this video, users write a lot of any other ways to resolving the problem
Did u also try replacing new keyboard? Did it fix the problem?
Yes, i try, it will not fix the problem.
See below comment pinned by me, there are two solutions that works in most cases.
@@DaneluRepairs Thanks. saved me from buying new keyboard. I will not worry about the keyboard anymore and just use the external keyboard.
@@Fuppa162 you're welcome.
Yeah, external keyboard is the easyest and cheapest way.
I believe that this Y540 is indeed a defective product, and I think the cause of all this is due to static charge
Problems with this model is because a through Windows updates, bios was updated, and this version of bios was bad programmer.
@@DaneluRepairs Is it true that Windows updates are the cause of this issue? Because I am using Linux, not Windows.
It might be the BIOS causing the problem.
@@flawless3055 yes, bios is messed up. At some people, Bios came through Windows Updates, at others, they manualy make Bios update.
@@flawless3055 I am also using linux and have the same problem, did you find any solution?
@JoseFrancisco-hz7op: read fist comment Fixed by me, that solution should work
Hello guys found any solution yet? Mine stopped working after a Windows update and now it´s completly dead. Already tried draining the batery the push the power button etc.
Sad to hear that. I don't find any solution because i not received to repair another y540. But, read all the comments here, there are several ways, maybe you find one.
If you find, please let us know.
Thanks.
Aun no saben si este problema tiene una solucion completa?
Este problema NO tiene una solución completa. Pero, lea todos los comentarios, hay algunos chicos que han encontrado varias soluciones, más o menos bien. deporte
Throttle L23 needs to be replaced, or jumpers must be installed instead for diagnostics.
"throttle" meaning acceleration... so, i don't understand your commnet; please write in your own language, in rusian, i'm gonna use google translate for better understanding; thanks.
@@DaneluRepairs Если посмотреть по схеме то на позиции L23 находится элемент, этот элемент и является причиной неисправности с клавиатурой. Если его выпаять и сделать перемычки то неисправность уйдет
@@DaneluRepairs но лучше вместо перемычки подобрать похожий элемент, я взял такой же с донорской материнской платы
@@user-sp8mu5so6e Хорошо, теперь я понимаю; вероятно, это катушка, этот элемент. У меня нет ноутбука или бракованной материнской платы, чтобы посмотреть, что там, но я найду это сам, когда и если снова столкнусь с этой проблемой.
Однако мне кажется крайне странным совпадение, что у многих людей с клавиатурой начались проблемы сразу после обновления биоса, полученного через обновление Windows или сделанного пользователем вручную.
Когда я снова столкнусь с проблемой, я вернусь со своей собственной информацией. А пока, большое спасибо.
@@DaneluRepairs Пожалуйста. Просто у меня был точно такой же ноутбук с идентичной неисправностью, что я только не перепробовал, замену контроллера, прошивки разные, но перепайка катушки решила проблему. Я так же не понимаю почему именно после обновления такая проблема произошла, но знаю точно что замена этого элемента устраняет неисправность с клавиатурой.
I have finally solved the keyboard problem by replacing the laptop battery. Pretty sure everything is fine now.
UPD: It's not working after all :(
Mate, i'm glad to be the battery reason of our problem; but, i don't think so. I even remember that a guy, below in comments, think exactly like you, and in few days, problem reappear.
Please leave a conclusion after few days or a month. Thank you.
@@DaneluRepairs Ohh.. it's been a week for me so far. I hope new battery will last for a year or something, it's pretty cheap to replace it.
@@big-game-dan a week with NO keyboard zero response problem?
@@DaneluRepairs Yes, now I'm turning my Legion Y540-15IRH off and turning it on without a fear of finding a way to bring the keyboard back to life like everytime.
@@big-game-dan that's really great news. Let's wait some another few days, till were too happy; i hope this was the problem...
Salut Daniele as avea si eu doua întrebări am același laptop merge cat merge apoi se închide ecranul gen sleep mode…tastatura nu mergea tot ca si la tine, ce spui ce as putea face ca nu merge deloc merge cat merge apoi intra in sleep am făcut setările sa nu intre in sleep dar tot intra ori își dă restart am reinstalat windowsul dar tot degeaba ce sugestii ai avea? Aștept răspunsul tau te salut :)
Salut. Referitor la tastatura, citește primul meu comentariu, este fixat de mine, fă ca acolo și dacă ai noroc, îți va refunctiona tastatura.
Cu problema a doua, referitor la sleep/restart, e mai complexa chestiunea. Trebuie detectat din ce motiv face și apoi rezolvat. As începe, dacă te pricepi bine, cu curățarea perfecta a sistemului de răcire (radiatoare și ventilatoare), pus pastă termică Arctic mx-4 bit.ly/Pasta-termoconductoare-Arctic-MX-4
Și, făcut update bios.
Cam astea ar fi. Trebuie sa ții cont ca este un laptop destul de vechi și sigur s-a jucat pe el mult și poate nu în condiții ok. Apropo, e al tău de nou?
Saluare,eu as vrea sa stiu daca imi poti spune cum sa o dezacivez tastatura de la un acelsi pc,pt ca vreau sa pun o alta tastatura peste cea de la leptop si vreau sa o dezactivez ca sa nu se apese butoanele de la tastatura pc-ului cu cea externa care o voi pune peste.Imi poti face un tuto sau explica etapele te rog.?.Mersi
salut; urmaresti video si la 12:11 stau cu degetul fix pe mufa flex care vine din tastatura; o scoti de acolo si gata
Hey how are you? Did you find some solution?
hello; i, personally, did not find any solution because i don't have a laptop to test some new ways to repair. Laptop from video belong to a customer. But, guys below in comments have several ways to repair, read and check them; good luck, mate.
Lo solucione sin tener que abrir el hardware
Awesome. How did you do it?
8 sec shotdown work thank u bratva taşaklarına kurban
Memnuniyetle 😊
Disable Fast Startup and restart your computer.
I do, no change. I'm aware about many problems that Fast startup create...
Salutare Daniel, ai reusit sa faci functionala tastatura ? Si eu intampin aceeasi problema, si nu mai stiu sincer ce as putea sa-i fac.
Salut Cross. Pe scurt, NU. Poți urmări clipul cu toate metodele încercate, multe la nr, dar, DEGEABA.
Apropo, de unde ești?
@@DaneluRepairs Din Iasi. Ohh, la mine s-a bulit din momentul in care am pus o tastatura externa la laptop. Ceea ce este ciudat e ca problema nu a aparut pana ce nu am facut update la windows 11. Pe windows 10 mi-a mers fara probleme chiar si utilizand aceeasi tastaura externa. Am incercat mai tot ceea ce era pe youtube, am ramas fara optiuni. Ma gandesc sa reinstalez windows-ul, dar nu cred ca va ajuta cu mare lucru asta.
@@TheVonCross pacat; nu are legatura cu windowsul sau cu faptul ca ai utilizat o tastatura externa; are legatura cu faptul ca windowsul a facut update de drivere si acum si 10 si 11 e in stare sa faca update si de bios; din momentul in care s-a facut update de bios, adio tastatura; nu mai stiu exact versiunea de bios cu probleme, dar de la ea incolo, nu mai ai ce face; daca te-ai uitat la video, eu i-am facut chiar si downgrade de bios si degeaba. Dar 100% asta s-a intamplat, cu update de bios facut de windows; oricum cei de la lenovo sunt foarte ....insert epitete... la faza asta, nu mai zic ca nici nu vorbim de vreo janghina de laptop, in ideea sa nu-ti para rau prea mult de el. Cand voi mai prinde vreun model de genul asta, si sa nu imi fie teama de repercusiuni, ca se poate si strica de tot laptopul, o sa mai studiez problema, ar mai fi ceva chestii de incercat; deocamadata, la acesta clientul a fost multumit ca i l-am facit sa porneasca si sa il poata folosi chiar si cu o tast externa, ca el il stricase de tot.
@@DaneluRepairs Da. Este destul de aiurea. Acum nu stiu daca este legat de Bios, deoarece prima data cand mi-a facut asta a fost imediat dupa ce am conectat tastatura pe noul win 11. Am facut un power off, power on cu tastatura externa scoasa si mi-a functionat din nou tastatura. Dupa aceea, a doua oara cand am conectat iar tastatura externa am avut un comportament ciudat, abia dupa a 4-a runda de conectare, tastatura laptopului a devenit inactiva. Cu toate ca HW este functionala, pot aprinde lumina de backlight cu 2 taste, iar touchpad-ul este functional. Ma gandesc sa nu fi fost un conflict in momentul in care win 11 a incercat sa instaleze driverul de tastatura. Este doar o presupunere.
@@TheVonCross uită-te la clip, sa vezi câte am încercat eu. Degeaba. Și sunt 99% sigur ca e din bios.
Poți cauta si pe net, sunt foarte multi fix cu aceeași problema. Și pe reditt sunt mulți.
Is it because bios messed it up? Try downgrade the bio version perhaps and test.
when you downgrade bios, there are part from bios that will NOT downgrade; for do that, have to dissansembly mainboard, desolder chip's and program with external programmer
@@DaneluRepairs Damn son,they screwed up big time. This product was top notsch back in the days.
@@LOOTLORD605 also, there was big money. And it's not that old...
@@DaneluRepairs 3 years old,its starting to get rusty nontheless, Its very great for what it is. Sold mine long time ago :) I love this design, Fun fact I still have the old videos from 2019 when I used it maxed out on the rtx 2060.

I had same problem. But if you turn on the computer before plug in the charger, keyboard will probably work.
Probably. But, it's a damn rubbish this situation...
that used to work for me but it stopped for some reason, now i just use an external keyboard but its annoying
holy shit that worked!
what was the issue with the laptop?
Used to work for me... not anymore. I just resigned to hibernation mode. For some reason the keyboard more reliably comes by. I don't know why, considering it still pretty much the same as shutting down.
