Sorin.i think there's something.also i have to say you should try more.still i am thinking something hiding in a shadow.you have to uncover that skill.👍. Every times i am learning from you.
check communication lines between IC and BQ and BIOS like caps and resistors that might be it
First time I've seen the BIOS being programmed via a keyboard connector! 🙂 Always learning something new 🙂
Hard to find bios obtained easily from a for parts laptop of the exact same model and year make yourself a library of bios images from such sources saves a lot of trouble
I just wonder, why Sorin not taking the EC chip out and check if it's still taking the same amount of amps, before ordering the new chip
that chip is freaking expensive
SPOILER:
Lesson I've learnt from this is always check you can get the BIOS version and have at least tried it before risking buying an expensive EC chip when you have this type of fault.
Learning everyday, i hope you make some profit with youtube and your videos.
❤❤❤❤ WoOoOoOoOoW nice
It was instructive
please someone recommend me thermal camera for laptop repairing
Mr Sorin. I have a very very strange and unique problem with my Alienware X15 r2 laptop . I7 12700h and RTX 3070ti. I hope you read this and can give me an idea what might be wrong .
My laptop works perfectly , for days and days as long as I don't turn it off , as long as I keep it in sleep mode .
But once I turn it off and instantly back on or reboot it, I get blinking error code "2red 3 blue" , which means" ram not found"
But if I wait 5 to 10min and turn it on the laptop turns on normal.
Now I have replaced the bios chip, but the problem is still there , so this s not it.
While the laptop is on I have run prime 95 and all kind of memory tests for 2 days, and no error has been showned, everything is perfect.
My next idea is to try and replace the EC chip
This is a very mysterious case I have never experienced, do u have any idea what is wrong ?
Please can u send the serial number
Regarding the bios. There is a support option for it.
It is rumoured that manufactures design their devices with Sorin in mind.
Those kind of faults, are like gamble. You don't know if you will get your money back when you order a replacement part.
You will lose your money or you will get payed for the part and also your job.
@electronicsrepairschool if you can wait, tomorrow i will come back to my lab: my girlfriend has the same laptop…i Think the motherboard is identical, and I can extract the bios for you!!!!
Model Name – S413EA-AM1887W
Product S/N – N1N0CX05U115014
Warranty Status – Out Of Warranty
Warranty Expiration Date – 2023/12/10
The warranty literally expired 7 days ago.
⚠22:10 What did you say? 😄
If it's liquid damage the keyboard could be faulty aswell. Did you try to disconnect the keyboard? Think there was a similar problem a few weeks ago where the laptop wouldn't start because of broken keyboard.
Sorin, why did the HDD and coil get warm? Testing without the hdd and injection of power to what else gets warm?
Sorin
Check SmBus charging chip.
Or resistor pull up resistor smbus.
Why you not checked this element???
Very bad 😢
Al so check current resistor on battery .
You giving up to early
OMG lol. Did Sorin just swear lol.
Hi Sorin , maybe its because of the ID pin of the battery the bQ chip can not ommunication wıth IO chıp
Why is hdd on. Remove the wifi adapter
Faulty keyboard .. remove kbd laptop will be ok. Had same problem
You should folow PowerOnSequence to see SLP_S3&S5 state. Maybe buyed EC chip are broken.
Asus "This Laptop will Self-Destruct…"..get Bios from working Asus..
i had this same issue . but i fixed that by reprograming the bios , can you give me the exact motherboard model
31:13 – Why you dont contact support so they give you files?
Sorin, programming the EC chip or at least trying to read it before replacing it would have shown if it was damaged or not especially since it was not shorted (may be for the next time). Any how I really enjoyed this video because it was very educational and you walked us through all aspects of the laptop power-up which I am still struggling to understand. Great work!
Is the PM chip good? Although they are enableing the main power rails they sometimes have issues controling the charge mosfets
Hi
1st check SM_D SM_C comminication on battery side is that going on means battery detected by io then This issue could be also from Thermal IC and Charging IC which is in connection with IO and battery and also with CPU .
IF Thermal IC NTC Resister or BJT is damaged it will not allow anyother Activity to happen even Battery Charging.
I have this bios! How do I contact you? F0062107.X421EAYB.201
Asus should be ashamed! I still use my trusty build like a tank Dell Precision M6400 from 2008!! And i can find ALL the software including the latest BIOS update on the Dell website. Even from a Dell M6400 build in 2008. Now THAT'S customer service! Dell is by far one of the very best laptop manufactures. Proof that Sorin don't get much Dell laptops. Just Junk Lenovo's…
👍👍👌👌
Thx for upload the video so we can learn more and more. Have a niice weekend ☺🥤🍕🍟
If I see that much money just for a chip, I try searching for a price for the whole MB or Laptop – lol -.
It's just a bad board; however, another great Sorin video. To watch the thought process was worth the admission price alone.
Which EC programmer he's using?
It needs few things to test on board before you do bios also.
I have fixed this machine last week with same fault
(14:05) Of course NO, you are not the only one who feels bad about failing, since my distant school days I bought everything for double (I even built the circuits on two breadboards) and at the exact moment when he (The instructor or teacher) wanted to see how it worked, they both failed! when half an hour before both were working fine. In today's real work life, it may happen that when the customer comes to pick up their device, it does not work! I take off my glasses, put both hands on my temples and look at the sky… Need I say more? All the best.
PS: That subject of logic & digital circuits made me suffer… Microprocessors? Another hellish stuff ☹.
Very educational all round!
Lesson 1:- Never buy Asus products.
The motherboard has lots of space to connect a normal pin type EC chip but they selected a BGA EC chip. And the motherboard has no silkscreen components marking.
What if battery needs to send an ok signal. I know not normally like this but designers are over engineering everything now. Try a different original battery? Otherwise PCH kaput .
I had used ASUS motherboards in many desktops machines, and had no problems with them. Good quality, price and Linux compatibility.That was about 10 years ago. I guess a lot had changed since then. CPU and memory chips soldered on the board is now a dead giveaway they want the board to fail early, but just out of warranty (can they arrange the failure in programing ??)
wow i saw lots of solder balls he didnt even try to get. i know hes a cheap fix guy, i watch him, but do the job right
so is the s1 programmer able to detect the type of ec chip automatically? or like other versions you need the schematics to get the chip programmed correctly. any one with info please answer. thanks
I watched the video a second time and I remember that regarding the fact that the battery is not charging, the problem could be with the first MOSFET….?
Does the bios version agree with the HW version, according to the sticker on the back of the laptop? What if the customer flashed the wrong bios.
could be dead cpu lol
Very very happy to see this repair:) 2 years ago i received a very similar asus laptop .. i programmedbrhr bios… i replaced the EC… and i made a lot of measurement … and after 2 week i stop trying to fix this motherboard … sometimes i think about this asus and now i'm happy because sorin not solved thr issue 🙂 🙂 🙂
