Nice video!! That chip is 3v3_ALW and 5v_ALW that always go to chipset. I got a Dell Precision 2 days ago with almost the same problem. Client said that laptop stopped working and now has some coil whine - that was true, and the coil whine was from 3v3 line that was almost shorted, like 20-25 ohms because of that small chip, which provide 3v3_ALW to chipset! Anyway, the chipset was wire inside :))))
For that model here in North America: Motherboard: LA-F991P Chipset: N17E-G1-A1 If I were the owner, I would think like when I go to a Las Vegas casino; Here you have all the “round corks” that I have left (my rest). Another way to say it: my last bet of the night: it would be the chipset. PS: Of course I want Sorin to do that delicate work ... All the best.
Hello Sorin! Perhaps it is time to get a BGA soldering station with pre-heater and start with CPU/ Chipset replacements?! Not many repairmen actually want to deal with these repairs, but there is always a way to acquire new skills. Soldering station costs around 500 euro, and you already have expensive tools like Thermal camera, battery analizer etc. This would be a nice addition to your workplace!
He has done chipsets before but soldering wasn't the problem. It was to "gamble" on the part not working. Apparently replacement cpus and chipsets all come from donor boards.
@@mikeh6286 HI, Yep, I have seen Sorin's attempts to replace chipset and the CPU. CPU was bent in one case and chipset was faulty in another case. My point is, if there is a problem with getting a working CPU or chipset, get a complete donor motherboard and de-solder/solder CPU or chipset yourself. To do this job correctly infrared soldering station is required as well as the reballing. I can hardly believe one can correctly replace such a big component with just the hot air and without reballing. Even if components (CPU or chipset) are 100% working, there is still a huge chance to fail the replacement anyway, if soldering station/ reballing is not used. This is why most technicians will not even attempt to do this job. its risky and time consuming.
@@lukedavis436 i repair board level for a local repair shop. I advise customer not to buy this laptop and not even replace the board. Once the 19v rail goes it takes gpu, pch etc with it. Most times the mosfet is bad. Replace it. Turns on, fan spin nothing. Cpu dead.
@@ДимитърАндонов-ъ7е its common on alot of other laptops nowdays. The resistance on the cpus now can be 2-3 ohms. I see it on other laptops to but your right, the circuit could do with more protection. Even fuses after the mosfets.
I always tell my customers; if you have the choice between a gaming desktop and a laptop, NEVER choose the laptop unless you absolutely must have the portability. If you want something to do work on the train, coffee shop etc, get a cheap laptop and leave the gaming desktop at home.
But the thing that I dont understand is why professional laptop doesnt have good configuration like gaming laptop? In my case, I didnt have choice because it was difficult to find pro laptop who can do video editing. Only gaming laptop can do correctly the job with correct budget.
I believe there was a short on the main line you kept the the probes for long time that was a long beep i don't think the capacitor was getting charged when you first tested it
Great job Sorin, i understand why u don't wont try replace chipset, because of even me drive my own business and customer never wont pay for your try if It fail, bye Francesco Timpano from Firenze Italy
Hi Sorin needs your valuable help. After replacing the Acer Predator Helios 300 Laptop LCD Panel, the Charging Light does not come on at all. There is no power to the laptop. At first the blue light came on and then unfortunately it went off. Many people on the Acer Forums experienced this problem after replacing the screen. Most of those who experienced this problem changed the LCD screen without removing the battery. Could this situation have caused a short circuit on the motherboard?
Please do something about the beeper in the meter. Your microphone seems to focus on it and it's about 3x louder than your voice at times and I can't make out what you're saying. Love your videos otherwise! :)
they do but in the split mili or so seconds that it takes the circuit to react, some of the power might go to the cpu, gpu or pch and thats enough to kill them
Hello, I have Acer predator Helios 300 it is 7 months old , it has problem where when I turn on the PC the keyboard light is turning on but the screen is not turning on, what is problem?
shorted chipset are pretty much dead so reflow is pointless. The better solution is to replace with working chipset but goodluck finding one with working condition
Also replacing it is a big gamble, with so much heat the board can even bend one way or another which will make it uneven surface and won't make contact on the balls

I absolutely HATE my predator helios 300. I live abroad and bought my predator from amazon. So warranty is seemingly impossible for me. The greatest issue i have with this laptop is the battery. Plugged in and within minutes battery stops charging and its only been 9-10 months since i bought this. Scouring through the internet for solution and its the same thing for most forums. Battery issue. Not gonna buy acer again.
Good morning guys I have this accer I was able to fix the same problem I just flashed the bios chip though might be different case with this particular one
Well done dear Sorin, proud of you!

it's hard to find an original working chipset

thank you for sharing the knowledge we really appreciate
remember guys, disable ur ab for sorin. he deserves it
No
no
I learn something every time! 😘
Unfortunate fault, but great tutorial! Thanks
9 out of 10 of these acer gaming laptop i cant fix due to shorted cpu, gpu and southbridge. Almost always the same with them
thats the reason why they are the cheapest gaming laptops - they use the cheapest components and obviously get damaged the most

Good work. You not have luck here.😢

On gaming laptops usually CPU or GPU got dameged, so very likely that you can find a spare working chipset.
and that's how we lose a expensive laptop
Great
it sure looked nice - seems to me the best gaming pc is desktop
why sometimes those input mosfets does not cut down the power when mboard is shorted?
they do but in the split mili or so seconds that it takes the circuit to react, some of the power might go to the cpu, gpu or pch and thats enough to kill them

Hello, i have same problem Acer predator Triton 2 years old. Did you fix your laptop? Thank you
Damn it, another acer gaming laptop, ok time to go for msi,lenovo
Or asus
skip gaming laptop, get yourself a nice gaming desktop and you won't regret every penny
Can anyone with a working helios 300 measure +VCC_GT while the laptop is ON and tell me what voltage it is? I have la-k862p motherboard
Why not reflow chipset as a solution?
shorted chipset are pretty much dead so reflow is pointless. The better solution is to replace with working chipset but goodluck finding one with working condition
Also replacing it is a big gamble, with so much heat the board can even bend one way or another which will make it uneven surface and won't make contact on the balls
Coustomer would be really annoyed but he has invested in the acer laptop so it would be a gamble to replace the chipset or get a new motherboard..
Look the chipset…it hasn’t cooled down…it’s normal that sooner or later it burns…the design is crap. Just to save a few cents in production
👍👍👌👌
Change it it can be done
I am now confused.
Another motherboard.....but i'm think'in...why the chipset don't have a heatsink?...a small one..why?..

Remove chipset and try.

Always Acer laptops 😂😂😂
Order new chipset and try to fix it in a video 😁
if it was so easy
@@maklogetrich2378 he can try still 😁
tricky fault
sad
Accer ar dum creepy hardware error
Good morning guys
I have this accer I was able to fix the same problem
I just flashed the bios chip though might be different case with this particular one
This is not the same problem. The chipset is shorted.

Stuff from Taiwan still as shit as it was in the 80s. This perception of quality is just an illusion.
Remove motherboard and poweron manually
😮
you joking, right?
Acer is realy trash, every secon gaming laptop is Acer...shm...
