A gentle respect for you Mr Sorin, even though ou keep filming the content, not pretending you always fixing motherboard, you are a frank, honest man, a big thank you Sir
for those who can't afford the Start chip programmer, i will prepare a video for you guys on how you can use the keyboard connector to program the super io, it's very easy...and remember that not all Super Io are programmable, and well done to my old teacher Mr Sorin for starting to focus on serious things, and let young boys jump mosfets. Anyway let me help, you need to remove the bios chip, from the bios chip you can extract the bin files for the super io, you extract those files and you use them to program the super io...It very easy for those who are newbies i will do another video showing how to extract the super io bin files from the main bios
Think this good point more and more system go use this.
So I would have to buy the io chip and then use a different programmer?
Do u have that video up
here is a tip to program ITE SIO on a Lenovo laptop. Make sure your chip is empty if not program sio with a blank file if your sio is a 128k file 128k full file in FF in hex editor after you program the blank file means your sio is empty. Now remove the CMOS battery and don't plug in the main battery Just connect the charger and wait for your main bios will flash your sio itself.
Isn't this related to "mirror code"? There are some notes on schematics, but can't find anything about it.
@@nosleep6344, This method works for every Lenovo and `Asus which have ITE Sio. I tested it and it works.
Nope, Lenovo nm-a311 does not program itself
How long does it take to program?
@@LEMON-xe3rx Didn't calculate that, but about 1-15 minutes per chip.
I think this is the most complicated job I've ever seen Sorin attempting. Well done, Sorin! I hope you get it fixed! I've been down that path myself many times - almost bought a programmer like yours for a single use.
Interestingly, like others are saying - and, in my case, completely by accident - the chip reprogrammed itself when I took out the battery and started the laptop on the charger only. Yeah, the battery was already off when I soldered the new chip, go figure that out...
One of the crazyest and most insane repair video on this Channel. Really entertaining.
Nu pot sa cred cat de interesant e canalul asta, relativ la altele asemanatoare. Multe multumiri!
(Intentional Romanian; Translation: This channel is really interesting compared to others, many thanks)
I found this video has really important and valuable information, now i need to start getting prepared for this kind of issues. thank you Sorin.
Great Job I learned so many things from you sorin. Thanks
Thank You. We have learnt a lot
The way I do it is tack one pin on two of the corners with the iron, you can then just press on it with the tweezers and use the hot air
I like your school very much and has taught me quite a bit I am currently building and repairing and restoring computers myself as well as building power supplies amplifiers and other electronic devices I still got a lot to learn I would like to go to your school but I'm not ready to be able to pay for it yet
just one note- i personalty prefer to solder by hand, and not use air in the new chips, they are very complex and sensitive... just replace a nuvoton in a strix board... like that. (old one out by air, clean pads, install new chip, and solder, fine tip blade or a sponge will make a easy and perfect job) cheers :)
fine tip blade or a sponge ? what do you mean by a sponge ?
Awesome breadboarding! You need a very steady hand to solder those connections.
Wow that was challenging job ❤
Sorin really love electronics its affecting us
When I'm soldering next to connectors I put 5-10mm wide, 0.8mm thick aluminium strips on the board on it's edge. You can bend it easily around the connector and components and it shields the heat. Works even when I change BGA chips on the board.
When I misplace the aluminium strips, a desptop pc pci-e slot cover works too.
Ive learn so much from you master, now so many laptop that i fix in my shop... ❤️❤️❤️😍😍😍
You can program this I/O Chip on other motherboard . Using Keyboard connection if you see such case.
Misto filme faci Sorin!
Sorin thank you for sharing and that was very interesting. The programmer is expensive?
Sorin, your showmanship has got better with time
Nice sparks at 7:23 🌩
Yeah im happy i have all the tools for that's. This pain in the ars.
That's what sets you apart from the rest, I think you're one of the best
Blinking led maybe for self programing i/o chips from main bios . (I am not completely sure)
Hello Sorin, doing well? What causes the I/O chip to short? Is it an internal capacitor?
Thanks alot ... I managed to follow along to confirming that my SIO chip is dead with an electrician multimeter ... sadly to me it is a dead laptop R.I.P
hi, is it possible to solder the chip in an old motherboard just to program it
to see the difference
may be it may work
note: a continuity test should be done first to ensure that all 14 pins are directly connected between the keyboard connector and the chip pin out.
What Screwdriver you use? Thank you!
You can covered and with aluminum tape under the thermal tape
hello, thanks for teaching us, I have a laptop Dell latitude e6410 when power on ,screen display few seconds and goes off yet the board remains on , am confused I don't how to do thanks
i had the same issue fixing m.2 nvmes to a Dell and HP. after plugin the m.2 laptop didn't come on.
After diagnosing i found that vcore mosfets were shorted. (Gate to Source) . after replacing again as soon as plugged the charger in again the vcore mosfet were shorted. i had to replace both the mosftets, then it started working again.
now I'm bit scared to do upgrades.
Sir please kindly explain new laptops battery BMS circuit and how to repair it...
I wish i can help Sorin sometimes with soldering. Because he is not cleaning solder pads and when you do that it is much easier to put chip on flat surface instead of little bumps on pads...but that is the way he is doing :D
Cleaning and keeping your irons clean seems to be a thing of my generation
The counter argument is that always cleaning small pads with tiny traces adds risk. I do either method, depending on the situation. Nothing worse than seeing a pad lift and realising you are making the device worse, not better. 🙂
@@OnStageLighting i know but when you have feel for how much pressure on board and temp to apply make job easier, but i know we all have some tricks for our working, nobody is the same...but if he put a blob on soldering iron and clean that way also is good (for him) but it is okay to exchange opinions i wish him good luck and also to you in future jobs mate :D
There are little pcbs on the market to solder on the chip and have bigger pads for connecting the programmer.
great job but if can you remove ITE Sio to adapter with another programmer and write ur dump
just asking if it would be neccesary to test the caps around after removing the bad IO chip before replacing the new one to see if the shot still exist. from what have learnt from you is tht it is always good to be coutious.maybe a m wrong,,maybe am right, but just asking
i mostly thing a write is unsucesful due curent limitation.. cuase is in the board around semiductors interfere.. i know this from other repair i done .. sometime oyu just have to pull more power.. but not everytime is work.. pls desolder chip and program it in SOCKET.. or on test solder board with no around semi.. i do use revelprog IS with FTDI breakboard
Maybe a keyboard controller ic the problem source.I didn't see it clearly in the video, but it looks like a couple of pins have touched another adjacent pin of the sio. Maybe that's why not all the programming pins are there.
Sorin big like for you whiling ti try, that is a big ➕️. Iven if you do not do
It is ok. At least you tell as how hard is it and how to find easy way. THANKS 😊
So many wires =))))) OMG why? Sergey Vertyanov devices have a special flexes for this operation XD XD XD
You flipped the ship !!!!
What’s the sio programmer make/model?? Tks!
I have some warton flux - great stuff but smells so rank!
Can you use a breadboard to program the chip rather than while it's on the motherboard?
Patient man
why dont u use keybord connector for flashing?
great video i got the svod programmer , but after many years i found it's not original. plus the newest io .bin are not available.
hi
my laptop was just repaired recently io chip was changed my question is after the io chip changes the laptop can perform a long time and please tell me how can i save my laptop from damaging io chip?? sorry for my bad english thanks.
i usually aligne the sio chip feet put some flux around it then put a metal nut on the sio chip and in one try it sits down under the weight of the nut
hello master, I installed intersil 95859C HRTZ X908FFQ instead of intersil 95859A HRTZ W638EZ8, it didn't work, I don't have a GL signal in the mosfet, I've been dealing with it for 2 weeks, please help
Hey mr sorin, chhers from.Argentina, inlove your videos, i recently made a similar job, programming an ec with a bunch of cables, and cimes an idea yo mention, my mistake was no to use commond ground between mother board and programmer, may be your solder motherboards ground to a fpc ancor point and not acctually ground on the;programmer?
That seems to be cheap thermal paste trying to look like liquid metal, but I am almost sure is non conductive. Why can't you tin the pads with unleaded solder? Makes the job alot easier.
hi sir I am a young man trying to learn how to repair like you but sir I wanted to ask can you do a video on basic repair like how to identify components and how to use the multimeter I would be glad
Bro, just watch the old videos he have. Remember """electronic school repair """ you welcome
he has all of this in older videos, just search :)
Check playlist :)
@@tachidaallentumoto2351 He won't make it. Not a character for learning. There are people who want learn and there are people who want be served.
so if it turns on then the io chip is fine?
what about all those shorted capacitors?
Thank you for this wonderful video Mr.Sorin...
I always get lost whenever you bring current into the motherboard using multimeter. I will love if you can dedicate a video on the use of multimeter for troubleshooting and also motherboard component and their functions...
Thanks.
Much love boss
Can be confusing at times because Sorin uses similar looking probes for the multimeter and power supply. You can usually tell which is being used / connected as the top left 'red' display is the power supply and the bottom 'white' display is the multimeter.
ok so which warton flux then?
You are a real professional , Amazing job, I really like watching your videos , thankyou for this high quality content
Hi Sorin
I fully respect your work and love your TH-cam channel, but i must ask why you used jumper wire to program the ITE8227E EC when you have the perfect programmer and could of used the Keyboard connector with ribbon cable, this would have saved you so so much time.
The schematic's show all the KO's , i've never had to program an ITE like that only MEC's using JTAG.
Keep up the good work and love the Saturday Morning "Lets have a Coffee"
yes ..this is what i was going to comment
EC is not connected directly to the keyboard port like other machines. This model EC is communicated in digital form with the keyboard management ic => the keyboard management ic will connect to the keyboard on the mainboard
@@luuduccpi2646 That may be so but it is still connected to the keyboard connector and can be reprogrammed by it, No need to hard wire direct, check the schematic and you will see for yourself.
@@alien-repairslike how he explained, the keyboard interface was not communicating directly to SIO chip.. it talks to another ITE chip and that ITE chip talks back to SIO chip..
@@ivanzsarjust look at the schematic and you will see kb is connected to super IO.
Why do you use wireless mouse?
35:34 haha 🤣 proper wire-spider
from my experience that kind of chip has to be soldered after with soldering iron from pin 1 to the last one and more flux to be 100% job done but after all good work sorin [after all i think u missed something doing the j-tag or chip is bad]
😊
The chip doesn't care what order you solder the pins in.
@@Brianck1971 it was for example from pin 1
How do I fix a Asus that no matter what I do nothing will let me actsess my Asus k55n I tryed just about every thing accept changing bios chip all Ctrl+what ever usb,s software ect. What am I missing????? I never not been able reinstall a pc
Hp is my favorite I have 2pavilion G7 4 pavilion 17g 119dx/113/121/G7
How can I fix it?
Maybe, are the keyboard controler messing with the pins u are trying to use to program the kbc?
Must check this...
Maybing just removing it of the board will let you to program the 8227...
Looks like if you have a big laptop you will get tge worse problem. Good luk with this one and hope see the result :)
At 20 volts 15 amps, "that's a nice charger". My laptop charger is 19.5 volts 16.9 amps. I purchased it from China to power my home made laptop. On testing, the power supply, it maxes out at 330 watts. But I'm sure the one in the video is better made than the charger I have. :-) Mine is a bit electrically noisy, but I have extra filtering on my laptop to handle it. On mine, instead of turning off, and staying off when overloaded, it turns off and on rapidly.
Ask for the programmed ic who you were talking with ❤❤❤
Iam a bit confused, there is type of chip that need to reprogram, and type of chip that doesnt need to reprogram. So how can you tell if it the type of chip that need to reprogram? Assuming without looking at schematic
Various methods. Datasheet (unprobable you can get it), ask online, deduce that from separate bin in bios update or deduce that from the list of chips of programmer.
The chip that "does not need reprogramming" in fact needs, but it will be automatically programmed at first boot.
well, you need to connect usb ground from programmer to mothrboard via usb cable. i would also recheck whole SuperIO chip connection to motherboard.
I have the same charger with my legion y530. It’s 230w charger.
The 300W charger that comes with some Legion laptops looks also very similar.
Hi everyone
What programmer is this? I have search on aliX and looked at a thousand pictures on google but can not
find it. Does anyone know the programmer model?
Thanx
Claus
i can t found it5507e for i9 ???
What are the chances to have a laptop with a dead sio? Is it worth to buy that expensive socket for a one time job
That charger is for a mobility scooter 🤣🤣
12:02 the cap the discoloration could be a bad cap
You put the chip upside down ?
OK, i understand all of this, but how on the first place so many EC/IO chips get burned? Like this motherboard looked mint? customer played with the motherboard without disconnecting the battery or its just a random thing?
I think it's because the users don't know they need to turn off the battery in the bios and the ec is somehow sensitive to replacing components under power.
Those 128 pin chips in all the devices, I solder with an iron. I'll try with a hot air next time as well :), thx.
I have a problem in my ASUS ROG laptop, when I plug in the charger it drains my battery and goes to 0% and then shutsdown and when I plug it in after a while it charges normally and goes to 100% and th battery sustains for 3-4 hours and the cycle repeats
If you see such messages in the Vertyanov, then your ITE chip is defective. We also have to fight with this all the time. From 10 ordered ECs, 1-3 pieces only work. We have this Tetris adapter and always test the ECs when they arrive.
As I see I/O legs are short or bad solder 😮this I/O programing by main bios..😊
I'm going to get to your school
Very great chances of faulty chip from China and also bypass paths by program it onboard. The paths can lower the signals from the programmer and make them low quality. If it is a reputable seller buy the programmed chip because the PC is there for too long and you are stuck with the job and customer waiting. Very beautiful job. Congratulations.
Or maybe a fake chip. Sometimes it is just an empty shell.
90% of those from faulty laptops. 50% of faulty laptops are shorted due people dropping screws on the powered motherboard and around half time the chip will die. so we get around 25% dead chips from random sellers.
As I see sio legs are shortet or bad soldering 😮
It is hard to open it especially the key board
Two of my friends have these machines and we tried figuring out why the carger is that overpowerd, till we enabled fastcharge in lenovo software, it charges then with over 100w the battery
Not that this helps with the fact that the batterie runs out way too fast anyways
The GPU can also take quite a lot of power. The RTX 3060 variant for example takes around 130W in performance mode for the GPU alone.
The mid range variants of this laptop do not need that 300w brick ( you can use a 230w instead). Im pretty sure Lenovo was just like : well, thats a lot of work to make 3-4 types of chargers , lets give everyone the 300w one
no wonder the official service centers would rather replace the entire motherboard
Add diagnostic steps and next task to your ticketing system. Two week, two months, don't need to try to remember all the devices you looked at and what should happen next. :-)
ive successfully program it8227e-192 onboard, using rt809f with peb-1 board extension., jtag mode
Do you know more about this? Which pins on kbd port?
@@nosleep6344 Pins will be motherboard specific. You need to work with the schematic...
@@FrozenHaxor I know how it works in general, but it's parallel port on kbc. I was curious about that jtag (it's different mode). Can't find much about it.
@@nosleep6344 It's a waste of time, nowadays we use SVOD programmer. You go in through keyboard connector, quick and clean job every time.
Aluminum foil much much better than kapton tape 100% tested
That's right
As I see I/O legs are short or bad solder 😮this I/O programing by main bios..
The laptop won't turn on if you don't connect the power button...
Purchase SVOD4
I I just started trying to do this business
Do, don't try.
when you take your measurements please use the microscoup thnks
Is it not "What a EC/IO chip replacement on a gaming laptop looks like"?. But main thing is electronics i know, could not resist though, hopefully oké.
2:38 ceramic thermal paste
Those io are programmable
20V 15A OMG 😯😯😯
This work is very difficult and exhausting. No one can do anything unless they have great capabilities
