Just repaired my wife's Lenovo L14 using your example. All I had to do was to unplug the BIOS battery, short the contacts and reconnect everything. Thanks so much for sharing you knowledge with all of us!! 😁👍
👍 Good one Sorin. Quick and nice fix, customer is happy and all good.
Buna ziua Sorin, felicitare pt cea mai rapida lucrare....Bravo!
Feeling spoilt today, mutiple Sorin uploads
I learn a lot from your chanel.. malaysian here
The T14 is easiest opened on the back of the laptop, the clips of the lid slide in the front where you started to open the laptop. I have a T14 Generation 3 that I have upgraded with a fingerprint button. They are so easy to work on and parts are available everywhere.
You just saved my daughers laptop. Live and greetings from Belgium
Thank you Grandpa... you saved my day!
With that light blue shirt you look like a Man City fan (triple crown) and I am convinced that by wearing it your luck for this day seems to change😊. Thanks for sharing. All the best.
I wish I get laptop faults like this :) (I usually get intermittent BSOD laptops to fix)
Nice job Sorin
Lol, I was happy too when you fixed it, thank you for your video
nice one Sorin, about time you get a easy one with some easy earn profit, thank's for explaining the bios functions and correlation with cpu
Sorin. i'm happy when i watching your video and you fixed complete.
Love what you do!
Damm 2 vids in a day ... Luxury
Nice sorin good job fast and clean perfect
Sorin, this Lenovo and some other business ones have a button at the back that you hold, I think it does the same thing to reset BIOS, can save you 2 min of your time :)
Good job mate 👍
I've had a few of these apart (still got an old X1 Carbon gen 1 sat on a shelf somewhere)
Today my Lenovo I have the same problem I fixed the same way thank you ، you saved me 😭
ADPID on the BQ chip is fun, had to disable this circuit on an acer predator i fixed to get it to start.
I am electronic also fixing everythinh and it’s interesting how we can find problem.
Thank you
normaly lenovo laptops has a hole to reset the bios and u dont need to open it I think that T14 model has it
I never thought one day I will watch a video of opening my laptop to fix it
i have a lenovo T470s laptop that wont power on and wont charge either and when adapter plugged in the indicator light doesnt show at all but when i test the power jack i get 20v power from the adapter. the indicator light is on a seperate micro board for usb. its mother board seems confusing. any advice Mr. yap been following different repairs of yours and used some here and there but this board i need some help to figure it out the board seems so compact.
Dit you check the voltage of the bios battery?
Thanks
Hi Sorin,
What microphone are you using?
there is a reset button at the bottom. at 1.00, you can see above the middle screw, there is a pin hole, you can poke it with a sim tool or whatever u can poke through. all T series has this reset hole, because of the bios freeze due to errors. all new ones have two bioses. but ec as u said gets corrupted for whatever reason.
Why on charging coil are 13v and not 19? Depends on how many cells has?
exelent i loved this video...
HI i can you help please I have a lenovo T480. when pressing the power button the power led turns on but no processing and no display. 3.3v, 5v is present, the 1.2v of ram is present. What can I do to solve.
Looks nice. Where can we buy it from ?
When you have knowledge always is simple. If it was simple the shop would take the money not the master 😀
7:32 Thanks for your video. Tell pls what device you are using in the charging port? 🖐
I heard there was a reset button on the back of the laptop. And we're supposed to push the button 3 times to reset it. Is this correct?
Hi, What do you charge for situation like this where it was a very short repair? What happens if you get a repair that isnt and when you turn it on it works?? Do you run it for a few hours just to be sure then call customer to say theres nothing wrong with it and charge a min fee?
the customer agree to pay 150 pound if it's done today
We currently have T14 and L14 were I work. Strange that the WiFi card is permanently attached to the mainboard - ??? I have a lot of L14 laptops that are having some kind of handshake or USB-C protocol issues when connected to a Dell WD19s dock - works with WD19 and Lenovo docks. T14 laptops do not have this problem. The problem is when (out of the box - both new WD19s and L14 - connect the dock to the laptop - blinking power light on both dock and laptop and some type of connect/disconnect sound from the laptop. Connect a Lenovo dock - works normally, then connect the L14 back to the Dell WD19s - no more blinking lights and the WD19s works normally?
I have a Lenovo T480 that doesn't charge and USB C port does not work. Do you have a video to repair this or advise? Kind regards
Hello sir im from malaysia 😄
Common issue on modern lenovos. I work in a company with around 2000 lenovo l490/495 on stock. We see a couple per day locked up won't boot need bios kicking to restore
Hi
I have lenovo thinkpad t450 it asked for restart to install windows 10 updates and i restarted it but it didnt turn on again and not even charging led show anything
in the future, start oppening from the back/ hinges and finish in the front by lifting the back
I have a thinkpad E14 11thgen and first it had an charging port issue and changed its port and now the prob is motherboard "they said" could you please any tips for solving the prob
How can I remove the supervisor password for this ThinkPad T14? Cannot find the eeprom
Smooooooooth
The number of devices now that have the equivalent of an EC chip running all the time waiting for you to press the power button. Particularly annoying with devices like electric toothbrushes, I've had to take mine apart, unsolder and resolder the battery to reset the microprocessor.
You have did also on desktop computer
You don’t have this jobs always because you have electronics knowledge 😊
Hello Boss where is your shop location ?
Sorin could you do a few test on different laptops with 12V power supply?
It will not charge, but I don't see any reason why it would't run just fine from 12V instead of 19V.
yeah, I don't see any reason why it wouldn't run without voltage at all...
As a business owner, I don't see any reason why employees wouldn't work just fine for half their salary.
@@alexisfrjp As a business owner, you are a very wise person.
God help us all and your employees, customers from such genius minds.
Let's check some voltages, but for a newbie where are the points of checking? How we can learn about those points without schematics ?
vezi ca are niste videouri unde explica pasii pe care ii urmeaza de obicei
T14 comes with a reset hole pin. I assume you reset that before opening the laptop? That's what we normally do. If it doesn't work, then we open it and unplug the battery, followed by a CMOS reset. It's an easy fix, sir. I'm not sure if you still intend to charge the client.
Yes it worked for me little hole without opening laptop
Enjoy the coffee from us 😂
Wat is the name of the usb-c checker?
@moskito2010: Just below the video screen is the description, if necessary click where it says More:
a) My Tools (click)
b) Icon or Photo 24 Items (click)
c) look for the image where it says AVHzY. All the best.
Ur ossam
Can you charge the bios battery?
No you cannot
I have a Lenovo Thinkpad T14s doing the same thing like this Laptop how do i solve the problem
could the bios battery be low and cause this problem ?
could check the bios batt volts with meter I guess, but that condition normally just results in Bios values reset to factory defaults inc. date & time
I thing this faults have to do with a electromagnetic interference like a mobile phone close to the laptop or static electricity but not sure ...
cool , i love this channel and I got highlighted comment
The reset has nothing to do with EC/SIO. When you are pulling out the CMOS battery, you are essentially resetting the Power management controller inside the PCH. A laptop which works by reseting CMOS will come back after somedays as it's a sign of PCH slowly dying inside. Since you are getting more laptop jobs now, you will learn this after sometime.
How do mean bro isn't that different
@@themuzer1301 , Nop. I speak from my experience. Some modern laptops doesn't came with a seperate CMOS battery but the main battery will have a pin which outputs 3v and functions as a replacement to the CR2032. In that models, unplugging and plugging the battery essentially is same as a CMOS reset.
@@anshadedavana yes, just like the Toshiba L50 series I'm using. it has no internal cmos battery, and when the battery die, the bios date and time always reset, and to stop the annoying correcting the date and time every time I turned it on, I bought a new laptop battery.
... it's coming quiet hard .... well, you need to open the base cover in the correct order: first the back, then the two sides and lastly the front. Also there is no need to open the laptop in case of a frozen BIOS: there is an emergency-reset hole in the base cover.
It doesn't always work the way it should.
i have an acer laptop that turn on (orange and blue led light) but the laptop is unresponsive, fan spin a bit and then off, display port not detecting external monitor, and usb port not detecting external mouse and keyboard. I almost conclude that the motherboard is faulty and need to send for motherboard repair. Turn out its all because of the previous user trying to upgrade the laptop using regular sodimm ram (DDR3) when in fact the laptop refuse to turn on simply because it needs low voltage ram (DDR3L). Hope this will help someone out there.
I have lenovo g40-70 board model it stop working and no power nor display what could be the problem , technician here wont repair they just say its motherboard problem but aome video like this im sure it can be repaired but i dont know how and im no technician
Same symptoms... but doesn't work for me..😢
Simples ,,,,, !!
This model 2 bios 32 mb😢
Easy money 💰💰😎☕
Please master reset bios paswoord thinkpad L14 Gen 1 core i5 10th pleaseeee sir
8:55. HEY. CLEAN THE FAN. ON ALL OF THEM YOUR RIGHT THERE. NO ONE ELSE WILL OR CAN CLEAN THE FAN
C..L..E..A..N.....I...TTT
Spring my guy
Hello 🤝👏👏👏👍👍👍👍👋👋👏
EZ Money...😊
Guyz just press tiny hole at back side and this problem will be solved without opening laptop.
Mistake: It's not the bios batterie you short, it's the circuit of the bios batterie lool!
I always update the BIOS to the latest version whenever I am tasked with such a job.
The 1 million question is: You going to charge the 150 pounds?
Does Lenovo that suck!this is simple but it doesn’t be so simple the problem?!
This is an extremely common fault with Lenovo.
Interesting that he immediately pulled the date and time from something! We don't even know what they have in those chips that are spying on us!
Windows had the date/time already
it pulled it from windows, if he would've gone into bios straight away the date would've been wrong but yes you are correct, Lenovo is as dirty as Huawei
@@Arachnoid_of_the_underverse No, date and time is placed in the bios, not in windows.
Easy £150......... Show Me The MONEY!!!!!!!
Again a Lenovo?
Ce zici de rusi..? ia Moldova?
