Love your humour. It's a pity you had to explain about the chip replacement but i suppose there would be viewers that might believe it. Make every job a challenge! Just a small explosion nothing weird!
Leaned even more from this video. All the puzzle pieces are falling together 😀 thank you sorin! Im making a block schematic because most laptops seem to use all the same chips.
@blootchy1: Yeah. (3:01 exactly and still image): a) I see a dark (circular) spot just above the gray band. b) I see 330.

well I have learnt from the master , I will never replace any component without dis connect battery first . The only thing I need to know is if battery is connected then laptop / phone etc will probably be f**ked
You can programm this via the connector next to it, it's usually a 15pin 0.5mm debug connector if there is a different KBC, if this is the kbc too, then you can use the keyboard connector. Also Asus boards autoprogram the EC most of the time.
Auto programming will happen only if the SIO is blank. But most of the time what we gets from China are refurbished chips which has already program in it !
@@fattymcboomboom9254 , You have to use Windows or the BIOS built in EZ-FLASH to update the whole BIOS including the EC. However that's possible with a dead board, obviously.
@@anshadedavana on my asus I was able to start the board with the power pin defective caused by a defective ite io chip by removin bios battery and laptop battery, then just plugging the powercord will actually autostart the board after a while.
😮Interesting. This board is very similar to HP also in the color of disposable boards. It seems to me that even on this board without a battery, the computer does not turn on. If a customer has replaced a screen, an estimator that remains short in the screen area. Either a cable output or a video card (in this case CPU). For a last attempt to disable A client's screen and connect an external screen. Maybe a miracle🙏🙏🙏
I have just replaced the IT5125e-128 and it worked without programming. The bios also contains the ec firmware. Asus vivobook X421IA, Bought it from aliexpress
Thank you Sorin, I would like to know if the battery should also be disconnected for mobile phones, tablets and others before disconnecting the screen?
You can't without power, ITE chip has to try to turn on first and then you can see if the chipsed is alive or not, or use the thermal camera if there is a Christmas tree on the chip 😄
Hey Sorin, here's a Question: *Did you have a specific reason for choosing the amscope SM-4TP and not the SM-4NTP model?* (The SM-4NTP is what Rossmann, TCRS circuit, etc uses) Also do you find you have to use the focus knob to stay in focus when you zoom with your microscope? (Or move the head up and down on the articulating arm to maintain Focus when you are changing magnification?)
Sorin is not using SM-4T. You can check his tools. It clearly says SM-4TP. And it makes a big difference. You cannot use both oculars with a camera at the same time on SM-4T. But on SM-4TP you can. It's massive difference. When it comes to SM-4NTP not sure how it is different.
@@TriodeTetrode Sorin just changed the link to the SM-4TP after seeing my comment. It was incorrectly linked to 4T prior to this change just made. He acknowledged it and thanked me for pointing it out.
Hi Sorin im asking a favor. I bought same board on ebay but with bios password and i can not find the original bios because i dont know the model. Would you send me the bios of this llaptop. Or at least the exact model of llaptop.
Those EC chips mainly contain a 8051 mikrocontroller and their software fits exactly to the board. I would not deny that there are officially available Mikrocontrollers which are exactly the same product. But I personally have never seen those. Probably those EC chips are really unique.
Hello. It's a wowstick, by xiaomi. Anyway if in any sorin's video you open the description, there is a link "my tools". There you can find the majority of the tool he uses.
@ngwanindi: In your browser type: wiki ldo regulator. (11:25) look at the part number on the plastic body of the component: 3H=5C type it into your browser. Find RT8249A/B/C (datasheet) and look closely at Pin Configurations (page 2). Terminals 3 and 13 are the answer to your question. All the best.
There’s a bulletin from asus stating that EC chip (it5125vg)failure is secondary to bad capacitors. That being said, your customer should be able to get warranty satisfaction
@@TheElectronicDilettante That is not the case for the laptop in the video. The EC chip did not fail. It, and probably the chipset, which is merged with the CPU, were shorted BY THE USER. No manufacturer would cover such a case.
sorin i saw in every electronist spare parts bag a led laser head lololol. I have too :)) i see in this video that is a chain defect , first goes pch after made a short in ec after in 3v ic xdd
Sometimes you can get the whole tested M/B from competing chinese sellers for 50 pounds anyway? and more and less depending on age and popularity. I get all my ipad boards from them and theres tons in those massive shopping districts where they just pull apart computers ect all day and sell the parts.
newer laptops suck....solderred ram...even some have soldered wifi etc etc....my new alienware has f*cking soldered ram on it...but 4 nvme slots?! why??? rather have 2 nvme slots and 2 ram slots
Sorin those ITE on asus have self flash when they are empty, all you need to do is replace and insert dc power for a minute. worth the try 11$ on ali

Nice one
Whenever the system power get short, ec chip get affected, mostly
Can you check if chipset is dead before replacing SUPERIO chip ?
You can't without power, ITE chip has to try to turn on first and then you can see if the chipsed is alive or not, or use the thermal camera if there is a Christmas tree on the chip 😄

Would you send me the bios of this llaptop.
Or at least the exact model of llaptop.
Look for the website biosbug
May be your laptop model is supported?
just ask on forum... it is in description

You do not need to replace the chip, just clean the charging port of the computer with thinner
Which electric screwdriver is that? Is it good? Last long?
It's a MiniWare ES15!
Just a quick question, is that a hole in a chip at 3:00 or just a company marking?
That's Capacitor
Ldo chip is not same. 2N is 3.3v always on and use Vclk. 3H is 3.3/5V always on and use Skipsel pin
Could you tell me how you know the chip information. I tried to find the data sheet but was unable to. How and where do you look? Thanks
RT8249C
You can use TPS51225C just cut 19 number track from the board. I've done this and works fine
Super🎉😊😊😊
question are all ec chips are different? I mean you can't find equal chips especially that they are programmable?
Those EC chips mainly contain a 8051 mikrocontroller and their software fits exactly to the board. I would not deny that there are officially available Mikrocontrollers which are exactly the same product. But I personally have never seen those. Probably those EC chips are really unique.
I will have satisfaction sir!

Hi sir what chip is LDO ?
Linear stabilizer as part of a PWM controller

EC chip failure, with chipset failure, because of user, is not covered by manufacturer.
@@yeahright9014if the user change the screen himself, then yes, out of warranty
@@yeahright9014 if your motherboard is listed on ASUS’s website for EC chip failures, then it’s absolutely on the manufacturer.

i see this chip on aliexpress for like 9£
Bad day at the office😂
3:00 seems to be burned ^^

5:10 charger port extra pin was in Acer ... do you remember?
I'm having a coffee....😊😊😊😊

It should be programed, and postage included with 40£.
Just replaced one and it doesn't need programming.
