This was an absolute masterclass in board repair! The way you handled the chip replacement and explained each part of the process is truly impressive. I learned a lot from this video-keep up the fantastic content!
I was curious what the chip was and did some digging. It's a UR0605B-XXXX made by Global Unichip Corporation for Google. It's the Google Titan/H1 security chip for Chromebooks. Talks to EC/AP, talks to EC EEPROM, tied into USB-C port. Can find it listed as H1 in chromebook schematics or UR0605B.
What I found strange is that after booting up the computer it appears to have reset the Chrome os back to factory default. Perhaps replacing that security chip caused the os to be reset.
The storage of those cheap chromebooks are often Flash based and accessed over the USB bus. So the chip could either provide power or the data lines for the flash memory goes through the chip.
@@mayamatuszczyk2436 Yes, on some of the cheaper chromebooks, eMMC (embedded multimedia card, aka a type of flash memory closely related to SD-Cards ) are sometimes run over the USB bus. I presume it is a cost cutting thing. Some of them even have a SD card slot on the board with an SD card hot snotted in place for the OS.
I had a similar issue with Lenovo Chromebook TPM security chip H1B3C. Cause: bad broken usb-c ports destroyed the SlimPort ANX7447 + diode ESD array + PI3usB9281 + H1B3C IC Good to know H1B2C is equivalent to H1B3C didn't know that, in my case I just ordered it from ebay. You probably have a bad usbc-port a bad slimPort IC (controller) or usb controller 2.0 3.0 controller (like PIUSBxxxx Ic's ). Also in your case is it a charging port on the left side, sometime laptop have 1 usbc for charging and the other only for accessories but you probably checker that.
I bought a Lenovo Chromebook off the internet for 100 dollars. It worked fine for about a week then all of a sudden it wouldn’t power up. I took it apart and examined the audio board on the right side and saw some chip components burned up. Because whoever owned it before me was charging it on the wrong usbc port. I got on a really nice website selling electronic components for older devices. That audio board only cost me 25 dollars and that is with shipping included. Gee I put that other audio board in and it fired right up. I wasn’t sure I would like it because it’s chrome os but I’m really happy to own that computer, thanks for the video on this.
When I had my first dead chromebook I researched this chip, which was shorted in mine, and found an in depth paper saying how it's a security chip and it sounded like it was coded to the motherboard and couldn't be replaced so I never tried. I have found this chip always fails especially with USB port damage. I wonder if it will let you log in with a chrome account.
@@JustInspiredKent I believe one can store some data on the physical device but resetting via ChromeOS wipes that data off. I wonder if replacing that chip caused the ChromeBook to reset to factory default. It seems that the splash screen on boot up may be the cause of replacing that chip.
At 5:10 MINUTE your thermal camera shows two chips getting hot. what made you ignore the first chip and go for the 2nd one? why didn't you replace the other chip you had identified at first?
Hi sorin, i suppose the bread and butter payment keep the work comming in, three or four cheap jobs out weight one three hour job, you cannot price a fault finding job unless you have a good idea what it is, and if the item is worth it! we live in a throw away society, you work hard to please the client, but you dont want the learning curve for yourself be compromised for the next job, cheap component are our nemesis, i would not be able to do a lot of repairs without my service equipment and these days the thermal camera seems to be common place, good job sorin well worked out, with a little help from your finger! £40.00 job i think at the least.
"should be fine, it's black, it's square"
You sir are hilarious.
🤣
Thanks for uploading every day videos. ❤❤

Nice find! Thank you for sharing!
Thanks for the info! Was also interested.

Thank you, man! But if this chip is dead, then it's game over, I think.
google pixel smartphone also use that kind of chip
Sorin, you're the best, Paul USA!

Makes sense.
I run a Linux "distro" for chromebooks and I've never seen a chromebook that has its internal storage connected on USB. It's eMMC on cheap ones.

That factory thermal paste is really something!
You are always the best
Nice repair 😊
Hi Sorin, good job...good to know the IC are equivalent.. bye Francesco Timpano from Florence Italy

yes, most cheap laptop only have 1 charging port, and the other usb c port only for data
why your comment is 23h ago and the video is 9 hours ago LOL !!

So... a chip known to fail is in charge of the users data, with no redundancy
At least Acer is learning from the best in the faild, Apple :))
@@IcecalGamer Wouldn't most of the Chromebook data be on the cloud or is there separate local storage that is not accessible via Google Drive etc?

One pizza and one slice 😂😂 you are funny Sorin…
Good job mate 👏
Very Nice! 😎
I just start getting your jokes. It's black and square 😂
I have never seen an old person move so fast after burning his finger!
14:46 NO! lol 🤣🤣
🤣🤣🤣🤣🤣
Sorin, i have same type laptop. Only one usb-c port used to a recharging.
Oh, so that 5V is normal on the left port?
At 5:10 MINUTE your thermal camera shows two chips getting hot. what made you ignore the first chip and go for the 2nd one? why didn't you replace the other chip you had identified at first?
the first chip is the chip which is supplying power to the second chip, thats why i ignored it
Nice one
Only paid 2 pizza slices. Great video.
Not a nice laptop, but a sexy motherboard 😂😂
Sorin my friend I hope all vedio you say: we have pictur crazy 🤣🤣
Is there a lightning symbol or "PD" to see beside the USB port? Then this is the charger port.
On fire with the jokes today. Love it 😂
if you don't know what the "black square duck" do, you lose the additional pizza slice !
No easy pizza today only Hot Dog now.
BArdzo dobra robota!!!
11:59 this scene reminded me ulqiorra fight !!!
First time sorin say sexy motherboard
Where's the Temu fan gone?
"This is not a niiice laptop" I don't think it is worth as much as the repair cost.
funny as always (black, square....).
Sorin's magic touch is a lot better than the thermal camera.
Chromebooks are little sketchy to boot. I have one which modified with Windows and larger capacity etc.. love it but little sketchy to boot sometimes.
How the port not working if it takes current
That was an easy (supermarket) pizza lol. For £30 I would just buy it in the supermarket or make my own. :))
Soin dont think its voice controlled lol, dot instruct the laptop via voice not 2 continue installation, nice work

👍👌👍👌
Proper sexy you don't say... 😂
That's a charging IC chip. So, I think it has a relation to the rest of the system chipset..
its because u remove the developer mode screw
if u test with the screws on it will boot on chrome os
Hardware security IC. Possibly developed by Google.
Otherwise... Really not much info related to it online.
I think it's a op amp
Hello sorin, whats going on about spiders in UK? Need to hear from you.
Wasn't it a Chromebook he applied 19V and totally fried it, ie, it ran on 5V - lol -.
Sexy motherboard 🤣😂🤣😂💪👍
it's black it's square, lol
this thermal paste from factory tho...
lol
i can see there a pizza ...... :)))))))))))))) another t-shirt logo ...
Chromebook, built to be thrown away, junk.
Chromebook=glorified browser
Yep
