ITE Super IO Chips from the factory are pre-programmed with default firmware that reads data from its SPI Lines. Most laptops are equipped with 2 Flash ICs, one for the PCH (M_BIOS) and one for the SuperIO (EC_BIOS). The EC_BIOS contains procedures & information on which GPIO pins are for Power Button, LED Notification, PowerOn, SusOn, PGood, PCH S0, etc. Some laptops don't have ECBIOS, so they use custom firmware manually programmed to the SuperIO's flash before usage. This is the reason why you didn't need to program the SuperIO. Be careful though, some laptops have Thunderbolt ICs that also use Flash ICs for Thunderbolt Firmware. Most modern Lenovo Thinkpads nowadays have 3 Flash ICs.
Even XPS have the same. UEFI, EC fw, Thunderbolt fw, and TPM fw
Hi @lazal3m where can I get IO chips.
@@solomonmaenetja2605 aliexpress
Interesting , im ganna be replacing a super io chip from a lenovo ideapad gaming laptop , since the cpu isnt getting a certain voltage from the chip . I assume the chip get programmed automaticaly?
@@lietus4192 what model of laptop? If it has a separaTe EC_BIOS FLASH chip then most probably you don't need to program the super io
Sorin, the super io was drawing current and getting hot. Doesn't mean it's dead. Could have been the dodgy dual MOSFET dragging the rail down. I would have taken that off first and checked v+ again
Thanks Sorin! I can't wait to see the programming of startup chip!
Sorin makes it look so easy... the mark of a true master
Thanks Sorin, everything is very clear and fast. Super Master :)
Another great work! I can't wait to see the programming of startup chip!
Great job like always love your videos Sorin would love to see the programming of the chip for the other laptops 💻 thank you for sharing your knowledge with us beginners THANK YOU
Thank you so much.
looking forward to watch your video programming the other SIO chip.
Super sorin, urmaresc mereu videoclipurile tale si astept de fiecare data cate ceva nou, eu nu pot lucra cu manusi
Excellent work Sorin
Thank you Sorin
It’s a nice job. It’s working great.
Looking forward to seeing the video on programming.
Thank you for the content Master
Thank you for yet another lesson
Thanks Sorin, The Video helped alot.
Am reparat un dell care a baut cafea, sau cola ca era tare lipicios si negru , cu alcool am curatat , si a fost ok a pornit si functioneaza perfect
Good job mate 👍
Nice work !
Nice man I had this one a 14s PAH board also dead. No amps draw and no led
Hi sorin, always glad watching your repair videos.
Favor please, where do you buy a pre programmed sio chips. Thanks
You have finally the svod3 or 4? 👍
Nice Work!
Thank u sir.
Nice surprised , Thank you
Hi sorin thanks for sharing your experience with us .
My laptop similar problem but on power button board I tested the 3.3v nothing is there no sign of voltage but when u click led blink on time
Thank you very much
Well Done!
thank you master
Yes please do a SIO programming.
Nice one
MSI GP6x, CX6x.. (uses similar motherboards all of them i don't know all their models though..) laptops example has SuperIO firmware on second EEPROM on the board. No need program if goes bad. P.S. Loved the MSI laptop.. i did unlock BIOS hidden menus which included all goodies like Overclocking intel iGPU and it worked. i got when using only iGPU higher FPS in Portal 2 lol. Got like 300MHz extra or so easily.
Sorin change the two circuits one minute, fast and easy
Because that is unleaded solder, it will take more heat and more time to resolder. Also the flux has lost properties after so much heat. That is why it is common to apply at least some leaded solder to mix and apply fresh flux. Makes the job easier.
Great, thank you
its a 300$ Laptop and a 5$ chip!
if thats a 1500$ Laptop, ok you are right! but in this case...its simply not worth!
@@Knebebelmeyer Flux and solder needed are a few cents. If one is charging dozens of pounds per job, can't he spend a few cents more? The thing here is being professional, and not fixing things over your knee.
🙋🏼♀️ Thanks!
yes time is money,so gotta do what you gotta do Sorin..will be interesting to see programming a chip has always been a bridge too far for me in past as a DIY..
It's my laptop too and it's very fine
I'm just curious how much is the repair cost for this. BTW great video. 👍
Good video. I want to know if it is difficult to change a USB Type C port on a pcb.
An SSD that could get hot right on top of the IO chip.... interesting design.
i so poor do not have even dollar but you are best teacher ever I wish you could teach me more I am in USA California hemet,ca.
Ow cool, seems you disabled that auto mute when sound level is below threshold. Much more relaxed listening to.
btw, don't throw those old chips away. They are worth money, contain Gold. With that many legs probably easy 3 grams of Gold a kilo.
Perfect
What a nice place to put the SuperIO on the board, just below one of the hottest elements on the motherboard.
Plz, HP, next time, put it over the CPU.
Nice 👌
i have the same board with the same problem... I don't know if it's a super io problem as the cpu does get hot when plugged.
where was the super io purchased?
Nice 👍🙂
That chip can be setup to use external memory or external instructions program from the bios chip. The engineer probably trying to use off the shelf part to create a simple and cheap diagnostic system. Maybe they are realise that the super io chip is not the best way to store a basic program. Because if the super io chip is damage they have noway to tell what might cause the problem systematically. So they use external chip to communicate with the super io chip. If the super io chip fail to return the communication, the diagnostic tool that they have can flag it as super io chip problem. It kinda smart way to debug a product. Instead building an expensive test jig, the can just intergrade a small diagnostic circuit into a product.
Great vid but i really want to see the programing. I dont understand how would you program it on the motherboard
SuperIO chip is directly connected to the Keyboard and Trackpad in all laptops. To program the SuperIO, the programmer would just need to remove the keyboard and plug the programmer to the Keyboard Connector. After this, you just need to run the programmer and check if it detects the SuperIO, if yes, then you can load the firmware. No soldering required.
hye sorin, i have same issue like this. do you sell the chip with program
HI Sorin I have dell optiplex 3050 7th generation 3.3v is present on the power button but when i press it nothing what else should i check guide please
I think for a laptop business a good programmer like the SVOD should pay for itself. (about 200€ from the original project shop, not the astronomic prizes some reseller ask for)
Sorin where do you buy that it8987e chip how do you its programmed ????
i got 3 hp17g119,113/ect in my shop i wish i good fix i just do not understand how or what is bad???
Show us programer you useeeeee :D if its ch431 thats old school but it helped me to save bricked board from bad bios flash
hi sorin, i think there is no need for you to program a brand new ITE SIO chip Just attach your blank SIO chip and the laptop should automatically flash a valid ec firmware from main bios. correct me if im wrong
For me what I do , I fast download the bios file. And if I find that there are two files but on the board I have one bios chip ( the main) then it means that the ec is within the Sio chip hence you need to program the Sio chip. But if it is only one bios file, and one bios chip on the board, then it means that the sio chip will program itself from the board.
Is that iTE also named KBC ?
I hope you did not hand over the laptop to the customer without cleaning the cooling fan :-))))))))) 🤔
By the way, that does not mean I apriciate your jobs and videos. Thanks for your time and effort.
Cool...
hello sorin, whats the mobo mark?
Why does that screwdriver turn the light on AFTER you press the button, you need the light on BEFORE so you can line-up the tip to the key/register of the screw head - lol -.
Salut, Sorine! Am o intrebare. Te urmaresc de ceva vreme. Repari laptopuri HP, Dell, Toshiba,Acer, dar nu am vazut nici un Fujitsu defect la tine pe canal. Ce se intampla , fujitsu nu se strica sau nu se cumpara ?! Cu stima!
Because they are not that common!😀
Good morning Sir. I got a one problem is that I have a Aspire E5-575 laptop. When I turn on it , it will disturbe near to another Laptop. Like usb port problem. It will flacutate. and display also blinking, but first laptop Aspire is smoothly running. Do you have any idea about this cause?
Sorin, what do you do when there is a stuck screw under the case? and it wont turn - a proper deformed screw.
Drill him out.
Use spot welder and weld the screw with a screw driver and it comes off easily
i have this superio on my z97 motherboard and its brocken so i need to replace it
i did that
never had this problem and i fixed 100 of pcs
Hi all. Where can i buy this electric screwdriver?
Why are these super io chips dying at the first place?
i am no way in any position to question the master but i have an itch saying to me if that was necessary to replace the chip as the mosfet was in need of replacing. maybe that was the only fault.
👍👍👍👍
i working on Asus k55n has admin password I can not get past tried every thing on line but went I put a USB or cd my PC turns off like PC no not gonna let you in????
How that happened? How an embedded controller can die? The dual mosfet? In this case. How a low power dual mosfet can die without a cause?
As long as the laptop is connected to the AC Adapter or there is a battery, there would always be 5v and 3.3v present. This means even if the laptop OS is turned off, the SuperIO is always running. Over time, due to heat and continuous power it will die out (ymmv). The only way to prevent this is to completely power off the motherboard by removing all power source. The 3v CMOS battery have no effect on this so you can leave it as is.
The only good thing that HP make is Brown Sauce .
Reason for the glove ?
Keep oils from his hands off customer's laptop. Or anything else really.
fingerprints and heat
2 weak ago i change bios on lenovo i5 gen 6
complete change EN25Q64 TO WINBOND 25Q64
I REMEMBER IN BIOS
EC VERSION =1.9
BIOS VERSION IS =32
I JUST REMOVE EN25Q64
INSTALL WINBOND 25Q64 (WITH NEW BIN FILE 8MEGABYTE COMPLE IMAGE FILE) NOT CAP FILE
AFTER INSTALL BIOS I SEE WUTH MY EYE "UPDATEING EC FILE"
I SAY NOT CAP FILE (CAP FILE IS MAIN BIOS AND EC FILE)
BUT I DONT EVER TOCH THE EC CHIP
AFTER ALL IN BIOS
EC VERSION =1.12
BIOS VERSION =39
IN BIOS FILE SOME WARE EC FILE HAVE A PRESENT
IF EC FAIL .OR OLD
AUTOMATIC REPLACE
Someone did answer with watch app message.
They copied the picture from Sorin. With number +180……it’s not from you I think?
Classicly manufactured laptop!
pavilions
i got no clue????
but still do not understand motherboard testing compleatly
man I wanna learn this but honestly is it a niche that is profitable for someone in a first world country? pmachine learning is probably more profitable i think
I'm surprised at how lax you seem to have become now you're working at home - I had expected that you'd have taken more care to be seen to carry out repairs more carefully and more professionally now that you're building up your own business. Not removing the damaged chip from the board and testing again to see if the io chip stopped heating up and also supplied the 3.3V to the start switch I found to be incomprehensible. Potentially it was a one visit fix, without having to wait for the new io chip to arrive - let alone being a cheaper fix for the customer. You neither removed nor even diluted the lead free solder on the board before replacing the chips, then didn't touch up the joints with an iron after using the hot air on them. I'm certainly nowhere near your level on expertise, but I'd definitely not be sending anything of mine for you to repair. Something seems to have changed...
Well just for fun I had tested colophony flux, which I also had made some time back. To be fair and exact on the topic I have been daily soldering for past 22 years since being child. So first - colophony flux burns out above 350C and it's even harder to remove it than any amtech or any similiar flux that hasn't been heated up prior removal. Second, magic Sorin flux is not very good for non leaded soldering referencing to my prior sentence earlier. I did mention on Asus laptop DC socket repair that soldering job is just poor and people here on YT were not very kind to put it up to perspective. Soldering is kind of an art combined with experience and it takes many burnt boards and no fixes to understand. Looks good on video though, but reality is diffrent. Objectively speaking I would send out job like this when I was still a child. Today I make joints better than factory and I don't need fancy stations and tips for that but I see tendency that big youtubers seem to push in the content fact that they have fancy equipment that somehow does the job but it's great because using own experience and brain is more hassle than using fancy tools. By this comment I mean no offense to anybody but as it goes we could argue with no limit. They have their experience, I have mine. I stopped making such comments but being sincere I see what you see and what i saw earlier and I can 100% agree that Sorin's job somehow got worse than it was before. Happy trails.
