this is your mistery chip: TVL ST23 04 AD0 it is a tvs array, it saved the rest of the board
That's what I was thinking off the top of my head, ie, some sort of double diode crowbar protection thingy - lol -.
how did you know that if I may ask?
Yep👍
Thanks !!!
the fact the chip was there, HP know someone will put the battery the wrong way 😂
12:24 C96KJ it is a simple ESD Protection chip (bunch of diodes inside). which can protect against ESD or polarity mistake.
The chip name is: TVLST2304AD0 or SU0524A6GTR or AZC099-04S. So the laptop can work without it (until another mistake with battery connection - then the damage will be worst :))
Hi Sorin, I think it is AZC099-04S ... a few diodes and a zener ESD Protection ... it's available and cheap, please replace it... you probably have it on some donor board.
Correct
@@Skarz289Hi.
Type ''chip component C96KJ'' in the search bar of your browser and you will have the equivalence:AZC099-04S.R7G AZC099-04S C96 SOT23-6, as simple as that, hope that help for the future...
Totally agree, if Sorin doesn't replace the chip, this laptop will probably last until it will need another battery replacement.
I agree with you! Coincidentally, I have another HP board here that uses the same IC and labels it D2400. From the look of things it provides ESD protection to the USB data lines.
No unknown chip ---> No burned unknown chip!
You improved the design: no chip, no dead chip!
The chip is AZC099-04S it’s used for ESD protection for high speed data lines
with this battery design that chip it is a must chip
My guess is that chip probably is a reverse polarity protection diode or a tvs diode ?
Yep TVS Diode and ESD protection
Hi Sorin,the chip is family of AZ099-04S and is an ESD protection with all diodes and 1 zener across pin 2 and 5 which is possible shorted out
The chip is
AZC099-04S
and it's a tvs array. Protection on 3v3 rail
Finaly I found in this episode what I was waiting for long time. You took repairs to next level and started removing and not replacing chips from motherboards. No chip no shorted chip. Still I think there is a lot components that are redundant. I am waiting for episode to strip motherboard for minimal components setup. Lets say processor, some resistors, IC chip maybe.
You seem upset
It's diodes protectors
protect sensitive components, which
are connected to data and transmission lines,
from over-voltage😊
Hi Sorin,
On Ali Express the Chich C96KJ is sold as a voltage regulator.
(20PCS AZC099-04S.R7G AZC099-04S C96 C96KJ SOT23-6 IN STOCK)
Nice one , the chip looks like a protection diode
I would assume the chip will ground the 3,3V when something goes wrong, such as the battery being plugged in the other way to protect the rest of the system.
I have this laptop and did the same thing because the new battery had the label on the opposite side (probably counterfeit) and I didn't pay attention to the connector orientation. Genius design HP! I replaced it with a C96KJ from the SD card reader daughterboard because I'll never use it and the laptop still works fine today.
check on da screen, check on da screen !
No chip, no problem. No capacitor, no problem.
Your mic is better now. Not so loud. It feels natural. 😊
👏👏👏perfect... your so being practical... where all voltages biasing is all fine... thats why i realy like to watch your videos...
Sorin for future faults, mark the top side of the battery with "this side up" or sth.
we have picture i can't believe we don't care that chip hahaha
Hi Folks,
No matter what kind of component, @ HP, it is registered in the obsolescence program.Cheers
Excellent work and video!
Hi. AZC099-04S Low Capacitance ESD Protection Array For High Speed Data Interfaces
What I found is that it should be AZC099-04S. It can be for video graphic card, USB 2.0 power and data lines
probably some kind of protection zener because it does not make sense that it has 3.3 on all pins except the ground!
It was, fine❤
Brilliant fix Sorin thanks
Probably just old standard hp tactic "protection diode" or how to call it :D
It's a proper calibrated wire placeholder. What else?
😂
Motherboard model 17889-1 L20713-601
It is for IO ESD protection.
If it's the Quanta sb8 rev. 3 schematic you need then yes I have it..
The chip seems to be a TVS diode array.
Hi, nice cool and educational videos, from what country you are ??
UK
that is an SOT-26 ESD protection diode.. with the marking code of TVLST2304AD0
I suspect that it is a "LSK489 SOT-23 6L ROHS" Low Noise, Monolithic Dual N-Channel JFET Amplifier
I saw 3 more chips which are seem useless. Could you take them out either to avoid causing problems in near future?
If laptop everything looks like fine means... I guess that's protection diode.
That is wistron board kind a hard to repair if no signs physical of damage
Hi Sorin, good job as Always, but think Is better you tell computer shop to replace It or the laptop live until next battery.. bye Francesco Timpano from Florence Italy
Now that you've removed the tvs array next time around if they replace the battery and screw up the polarity KABOOM goes the laptop.
Alibaba has chip C96KJ listed as a voltage regulator.
Hi Sorin, maybe there is a chip for typical application.
For SD Card driver or LAN port or USB port.
HP or lenovo which do i avoid more?
AZC099-04S C96 C96KJ SOT23-6
protection for usb I guess
Look for "HP Envy TouchSmart 15 15SBGV2D-6050A2548101-MB-A02" boardview "D9001"
Thank you. Looking at this motherboard, can you describe to me how to identify the power switch connector? I don't have a schematic. TIA for your help with this.
Apple made a call to HP to do this to make sure Sorin will never be the king of England. If he will be the king he will have access to schematic, data sheets and what he needs to make a proper callibrated repair with original parts at a fair price. By letting the customer be able to plug in the battery 2 ways will make a statment that only HP (i mean Apple) can make this kind of high level repair with a motherboard repair (replacement with a new laptop with the price of 2). This way it will prevent Sorin to accept his defeat and throw the laptop in the ocean and make the planet go under. This is a true story trust me...
i think this is the correct one
AZC099-04S ESD diode group
I think just "Overvoltage protection"
That should be a protection. You have normally 3.3 voltage on each pin, but when reverse the polarity, what happens there?
I think its a crowbar chip . it dead short to protect the circuits
Looks like it is step down controller comes under SOT23
Hi, Sorin! Im serching for ,,ok,, thermocamera. Not the expensive one, but what could you suggest for the beginner?
Hello🤝
AZC099-04S
Low Capacitance ESD Protection Array
For High Speed Data Interfaces
Revision 👋👋👋👋👋
It is a proper calibrated duck...
Hi everyone I've got an asus rog strix gl series with a wird problem . Bios menu works fine but when post (loading windows ) it suddently turn off . Its like cutting the power . Anyone any ideea or advice ( is not the ram memory or sdd already tried . Thanks in advance
It is a azc099-04s
AZC099-04S C96, ESD chip
ASUS X550LC has this part from reading google
Someone put battery label sticker wrong side of the battery clearly.
I think chip was used to protect the motherboard from wrong battery and wrong power supply
Has to be a reverse diode but that's crazy.
Ten chip to zabezpieczenie zapewne linii danych bateria EC. Bez niego też będzie działało.
Boa dica
Bad design and bad battery label emplacement the manufacturer should've put it on the other side of the battery
But first to say Free Julian. Assange now.
The screws holes from the batterie tells allot , no ? 😑
Nice repair ❤👍👍👍
I think for usb
AZC099-04S
the chip is made by worldway electonics
NO! that is simply one of the vulture-like companies that re-sells IC
Lots of battery jobs recently!
That is voltage limiter
Not hurt our screen😅
HP = Hinge Problem ;)
It wont break the bank Sorin less then 10p for a new chip,please replace it
Sorin, i´ts a mosfet power supply ic
Thought the motherboard had the part number printed next to the chip?
No, that's just a generic reference for each component followed by a serial number. i.e: R for resistors, RN for resistor networks, D for diodes, F for fuses, C for capacitors etc. Unfortunately, in this case, EU is not a common designator for TVS diodes.
Ah ok, apologizes, great vid's though @@viniciusvbf22
He did read the marking on the chip but refused to spend 10 seconds to google it. He engaged with his audience by asking anyone know what this is
power ic,you found this ic on ebay
That chip is a transient suppressor. I'm surprised you didn't know that since you work on a lot of laptops. HP likes to put a lot of these all over their boards.
That's stupid why is the label of the battery on the wrong side?
17" laptop :)
That battery design is "proper stupid". Don't laptop batteries have the sticker with all the text and markings, on the side where it can be read as soon as you open the laptop?
it's likely to be Chinese copy battery. original batteries are VERY expensive and most people will not buy it. The Chinese copy has the label on the wrong side because Chinese copy factory doesn't care about quality control, they only care about money ;-)
They are supposed to. Glad the issue was one that is easily fixed though. Those TVS diodes are awsome for protecting laser diodes BTW, solder them in as close as possible and no ESD problems ❤
ESD Diode 🦆 🤷🏼♂️
Can't believe 😂😂😂
c96kj mosfet
it is AZC099-04S
It’s a smoking 🚬 chip maybe it’s stopped smoking 🚬 now😂
maybe needs a proper calibrated wire.,😜
“Who cares anyway”
So you can replace with a proper calibrated NOTHING :D :D :D
Act as a diode
Hello 🤣😂🤣😂🤣😂👍👍👍👏👏👏👋👋👋👋
3 wtf ?
First
Another dodgy repair.
HP probably calls this the idiot protection chip, especially integrated into the motherboard for the people that don't check the manual on how to replace the battery 🥲
the true idiot is the design engineer who put the battery connector exactly in the middle so it is reversible.
