Lenovo Y700 dead, no power - BQ24780S & IT8371E diagnose step by step - Part 1

[@markdiii]

I repaired my Toshiba laptop because of this. Thank you so much Sorin! It's a BQ chip shorted. I replaced it. I thought the first mosfet is the problem then I saw this video, when I checked the BQ chip I don't see the 6volts.

[@JustInspiredKent]

Nice. Well done!

[@crawfordpritchard9604]

Nice one! 👍

[@gboyabraham568]

I have issue like that all coil are ok but before I go to Sio let me check the battery ic bcos I think since I have 19v on CLR I believe 19vlines is ok

[@jurgenkruger3932]

That's what we are talking about! Well done!

I forgot about the Y700! I wanted that laptop so bad back in the day! Crazy about the delamination of the screen from the glass, dang.

[@teslasapple]

Check the charge port for damage/dry joint…often charger voltage spike on Charger I.D. Pin kills the EC

[@JustInspiredKent]

Good point.

[@naprawafix-it]

We have a very nice video 😀 Great job, I learned a lot from you.

[@LordAnubis0909]

This was a great video. How to look for a fault.... Epic. Ty so much

[@theroguetomato5362]

Someday I want you to say, "And this time, we have a crappy laptop to repair."

[@crawfordpritchard9604]

Good Video and hope they go ahead for part 2. 2015 date on the motherboard with GTX so a bit old but still worth saving with dedicated GPU chip but depends on EC price I suppose.

[@martinharmath1566]

Sorin please upload continued video..I am interested about replacing power ic

[@filda2005]

6:00

[@zentechnician]

Is that uncured loca between the screen and digitizer? Don't let it leak out, it makes a horrible mess. I have Dell I got from a client leaking loca glue. I guess someone skipped the UV curing or maybe the build was too weak or something or whatever digitizers they bought don't allow the UV through to cure the adhesive. Be glad it isn't leaking. Just a frigging nightmare.

[@safn1949]

Dell XFR and Motion Computing tablets were famous for leaking LCD's, it is a horrific mess and then you get bubbles and goop.

[@stacyg3802]

Nice work deducing Sorin!

[@oaba201]

Finally a nice laptop.

lol good comment. Thanks for this 🤣

[@mihaioleniuc1642]

Very Nice! 😎

[@Headingmashine1]

Lol. I asked you on your sunday live about mine problem, where i had only 1v after mosfets. You told me about bq chip. So i replace it, then i got exactly the same second problem. IO chip is dead. So i gave up. I don't have conditions to reprogramme a new one.

[@maklogetrich2378]

EC chip sometimes can program itself from bios chip, might worth to try

[@Headingmashine1]

@@maklogetrich2378 Yeah, i might try it.

[@dirindirin3983]

Perfect

[@Pihmusik-PiCh-Expert]

[@knightwar3]

So it's always good to check the SIO before replacing any bq chip

[@vivaan138]

Sorin please repair a Lenovo legion y540

[@ootyguy9805]

Too sad to not see the final closing statement "we have picture, I can't believe" maybe we will see it in the next part!

[@amybella]

The chip can also be found on Amazon

[@viniciusvbf22]

Nice! Was that a hole in the SIO Chip (first "o" of Lenovo) at 17:50? Looks like it's right above the heat spot. (Maybe not. It's not there again at 22:00)

[@asgsgaer]

On what temperature do you use hot air?

[@stevejones4618]

Badly applied screen protector.... And that ribbon cable looks super dodgy.

[@sniper5406]

18:39 the Super IO have a hole on it so no need to test

[@DownButNotOutYet]

Yep, as he raised current you see a steam bubble come out and float left across the chips logo, after seeing that it's easy to see the hole.

[@samsscia]

Is it possible to post a list of common i/c part numbers to order for start up inventory? Most of us do not have a bunch of spare boards Thanks.

[@Vander-from-zaun]

sorin last week i had asus laptop with bq24780s what happened with you is exactly 100% like me now i am waiting new ite sio it looks like this bq chip is connected to sio and they go bad together

[@Gonzi-ze1sk]

what the effect of rosin when soldering?

[@toolsarecool]

Flux, helps the solder flow and limit oxidation

[@saheemgotnorizzz]

Hello guys, I own an Asus Tuf F15 RTX3050 Variant. The problem that im facing is that, my shift and m key both works finw individually, but as soon as I try shift+m , no output is generated. Also when I run cmd as an administrator, I face no issue in typing shift+m Can anyone plzz help me? Ive tryed using external keyboard

[@maklogetrich2378]

dodgy keyboard, replace a new one

[@hmartinlb]

wow this laptop is cursed. maybe lightning strike or something? how can multiple things fail at once otherwise?

[@XantheFIN]

I disgusted that flex cable colour at the corner. Eww yuck. I thought there was hole on EC chip if you look closer at middle "o" character.
