this is amd platform , lenovo laptops can program their EC chips from main bios only on intel boards , aslo that only works when EC chip is new (has no programing - all fffff in memory)

I love the way he gets excited when he manages to fix a troubled device. Makes me smile.

The satisfaction at "We have picture". Sometimes I be anxious that it is not going to show. Then I remember it is not a live video.

Thank you Sorin! I don't know how you knew that I needed this test!? Indeed, I can not program this EC with my programmer rt809h. Very nice EC soldering technique 😉👍! Your colleague will be glad for what you have done for him 🤗!!

Brilliant fix and thanks for the knowledge you share with us all 😊

22:05 best moment every vid Sorin! Another great repair! ☺

Sorin, don't say they repaired us, but you repaired it! Congratulations as usual!

Another nice repair. I can’t believe it!

Excellent as usual. 😊

perfect job. thank you .

It is nearly perfect, LOL, i never seen a more 90°, Talk about perpendicular, Excellent soldering and programming Sorin!

Good job mate

Interesting the test if it work without programming... thank to share again... bye Francesco Timpano from Florence Italy

nice repair!

Super...Thanks ...For...Videos ....👍

nice work

Can you believe that... It's work king 👑

My OCD simply wouldn't let me leave the chip crooked like that :D Once again, very good job electronics jedi :D

Very nice

LOL I have found myself saying the same as you when i fix something now, "It's working! That's crazy!".

Thank you! We have a situation with a shorted EC chip. Ordered a new one, a pre-programmed version from AliExpress. We found the EC firmware in our BIOS. Here's the thing - microcontrollers need to have a BOOTLOADER on them in order to take on new firmware on the fly, through their SPI port, without special programming voltages and signals such as from the programmer. When the BIOS gets an update, I think it tries to flash the EC with the updated firmware as well, but that can only happen when the EC has an existing program on it. By erasing it completely, the EC cannot get the firmware from BIOS. I'm unaware if stock (non-preprogrammed) AliExpress ECs have bootloaders.

The Best

First and always present Maestro.

Just an idea, maybe you could solder the opposing corners of the chip, with soldering iron, to keep it in place and then come with the hot air

A database with the EC chips that need to be programmed would be great 😁

When i hear "good job" then i gets calm.😊

All motherboards with SR40B are coming on without EC chip installed! All voltages are on, 3.3v, 5v, 1vPCH, even the power on voltage is present (only on the ones with power button on keyboard) on the motherboards that have a second ITE chip that i belive has something to do with kb and rgb lights. Ive seen this mostly on Asus motherboards, not on Lenovo!

Its working we picture 😂😂 funny sorin

Satellite programs these chips and the laptop can be offline. A secret list, similar to Napster download. Phones also do this offline. Nokia phone has a secret power bank inverter in the old battery, turns on offline without net connection.

Hi Sorin What is the adapter that you are using on your EZP programmer to program the chip?

That is a SVOD programmer not EZP and SVOD has an option for this adapter.

Hi I did have the same issue but when i removed the ec the laptop didn't turn on there was no led light and after that i purchased new ec which was programed but laptop didn't turn on and there was no led what should i do

¿Cuál programador uso?

Sir do you have any laptop technician requirement....

this is exactly my problem..I am waiting for power IC ITE 8587E to replace and was curious if it will work without programming..anybody knows?

Hi Sorin. As you, I have the SVOD with the 128 pin ZIF socket. In theory, as you had soldered the EC, the SVOD is capable of programming it via the keyboard connector The practice is different...I 'd programmed several ECs before they lauch the ZIF socket, but with a little degree of sucess (I mean, throught the keyboard connector and the SVOD). But maybe you could have programmed it via the keyboard connector in the motherboard. By this way, you avoid to remove an already well soldered EC chip... Thanks for the video!.

Hi sorin I have Lenovo legion 5 that recently start acting crazy sometimes it's working sometimes not then I smell a burn from the motherboard after checking I found chip was burn some current ic control it's marked as (UX2) on motherboard so after checking online ifiund the chip number (g2898kd1u) so please if you can check this ic and tell me if I can bypass this chip because no one have it and I cannot buy it online the shipping is to pricey where I live , it will be It will be of great help from you in this

Normally we should be able. But I couldn't figured out with my RT809H. Maybe my EC was a fake one.

chips are hardware and for several years they need software to "run"
