Acer Nitro 5 - Intel chipset PCH replacement

[@kenwamasho]

I really admire your confidence when replacing that chip set.

[@evandrocarlos1509]

Made bga soldering look easy. First time I see someone doing it at the manual station, standing ovation.

[@robbirobson7330]

did this for years i even soldered chipset on a camping gas stove

[@evandrocarlos1509]

@@robbirobson7330 it really makes the job apparently easier, because usually you have all the preparation and you're already there and you're afraid of going wrong.

[@robbirobson7330]

@@evandrocarlos1509 i know i bought a bga station after that it increased the success rate a lot. i fixed a lot of hp laptops back in the day with failed nvidia chip.

Sorin use his 6th sense when he suddenly put more flux and immediately the chipset start moving perfectly. Very experienced, respect 👍👍👍

[@PCEYTube]

If you disconnect the screen from the motherboard the HDMI output will work before Windows loads. Well done Sorin this is a harder than it looks. Biggest challenge is getting a working chip.

[@2368rafa]

Hello Sorin, it's an excellent job, without having a reballing machine for this and doing it like you and that it turns out perfect, you're a great professional. Thank you very much for teaching us.

[@user-yc7vc9ql6l]

On my BGA machine I put a one penny on top of the chip and I put a tiny bit of solder on the chip itself. When it melts it’s fixed. I have fixed tons of laptops like this

[@justinc9991]

I can’t believe how lucky you are!!! The shift pch did when it positioned itself shows me it was way off it desired position… judging by the 0.3mm balls on pch, it nearly impossible to not have solder bridges underneath it… lucky lucky lucky!

[@hristiqndimitrov5249]

I was thinking the same thing super duper lucky with how much it traveled to align

[@ErrorXTech]

I wonder why there is no voltage protection or fuse for the chipset to prevent it from blowing up on such an occasion.

[@wisabid4025]

I just love the way you work with explanation sir❤

[@easierrogue]

On some laptops it may be possible to use the hdmi as the main screen (incl. bios etc) if u disconnect the internal screen connector before starting up. 😃

[@OriginalFinnish22]

Just closing lid is usually enought, my tuf A15 has a faulty screen but can run 2 2k monitors trough HDMI and USB-C Dp, the panda brand panels are complete crap anyway. Keyboards and Mouses are cheap.

[@xDaRkModEx]

Yeah this worked on my msi gf63 laptop when the screen was broken. Got into bios and everything through HDMI.

[@PCmaniak]

Exactly ! disconnected is almost always a certainty 😊... This is the first I've heard of a closed lid... thanks for the tip😄

[@glazyrap9244]

you did amazing job , but my concern is that if you blowing air in so tight zone you can bend the board and after a while the balls between chip and board to unsoldering. Sunt si eu tot roman, si te salut si mult respect pt ceea ce faci! Esti mentorul meu!

[@viniciusvbf22]

Amazing work. Nothing short of amazing. People who are saying this was luck must have not see you doing it the first time. TWICE. I may never be able to do that. Well done!

Excellent work Sorin! A human BGA machine 😀

[@jaym5938]

I'm amazed that the board didn't burn with all that heat for so long. I would be too apprehensive about it. Great fix. Too bad the screen wasn't salvageable.

[@InfoDav]

Big PCBs like that are very resilient.

[@robbirobson7330]

he actually burned a hole in the board but you can't see it because the chipset is on top

[@realMrVent]

[@snitra.]

Hello Sorin, Just noticed that you are checking if the chip was moving by touching it with tweezers from the top, If you don't mind me saying that: the best way to check if the chip is soldered is to slightly poke it from its side and you should see it snapping back into it's place. thanks

[@rivciks5045]

Aligning the chip that's the biggest challenge

[@demontagemontage]

شكرا

[@81506860]

Nice job, Sorin ..but how do you manage to heat up the board so high from behind (on the spot) without being afraid that the components will fall down (a few resistors etc. could be seen there). And: do you have a jig to put the board on or do you have a table with a big hole that you blow the hot air stream through? During the soldering process you always only watch the board from above - how do you control the airflow from below at the same time when you have to be sure that it hits exactly where you want it? Well, soo many questions :)

[@PCmaniak]

Hi, the surface tension of the tin will hold them there .. of course you mustn't handle the board like a m....... calm hands .. no sudden movements with the board😉

[@ErrorXTech]

That's CrAaaZy I wonder why there is no voltage protection or fuse for the chipset to prevent it from blowing up on such an occasion.

[@PCmaniak]

Hi Sorin, on most laptop boards you can force output to hdmi / vga by disconnecting the internal display, even without HDD/SSD 😊

Just to test .. place an nvme with windows 10... connect the eth cable... wait some minutes.. and after automatic drivers installation you can switch to hdmi using win+p ... ( or just disconnect the screen cable )

[@1marcos55]

You need BGA rework with lead free profile, hot air just head can blow these chips or make bubbles, some motherboards have more heat resist

[@ovidiuovidius]

Bună sir Sorin! Pe când continuarea? O seară frumoasă!

[@kakkoishonen]

I hurts me you are doing a chipset replacement without using a preheater 😭😭😭 It's mandatory that you use a preheater when you work on a big chipset like that otherwise you are killing it instantly. Without a preheater the PCB will eat all the heat before reaching the solder melting point and because of that the silicon would be exposed to a dangerous temperature for a long time, enough to destroy it or timebomb killing its internal nano connections inside.

[@Davysguru]

Sometimes things are not as complicated as you think. You will find out when you have enough experience😊

[@kakkoishonen]

@@Davysguru that's not how you do it if you're experienced enough handling BGA chips.

[@seckinseckin3919]

@@Davysguru he is right. preheater is better solution. i have experience on repair.

[@smoothjazzfusionslowbluesb2630]

that's why he heated the circuit from the bottom, It happened to me to explode a CPU of a phone because it was super hot that day and I always use the same temperature on my hot air, a mistake on my part

[@lvlup2]

if you disconnect the display connector it should output on the HDMI by default for Intel and AMD laptops

[@XantheFIN]

Depends too on BIOS default settings if laptop starts output hdmi, vga when booted up.

[@twx8626]

Usually if there are 2 screens connected, the BIOS will default to a laptop screen. Whenever it doesn't recognize a screen, it will go straight to HD...especially new screens 120-166 HZ, there are malfunctions, so immediately deactivate a client's screen and check through the HD output

[@Noman22410]

my laptop is the same as the one in the video with the same problem.

[@majong_da]

I'm curious about motherboard bending because nowadays laptops have a lot of copper and a lot of layers so linear thermal expansion may seriously bend the board or even some traces may break. I'm thinking about bottom preheater. Additionaly you can reball it with lead solder

[@iTCXtreme]

[@josephdavid816]

[@TheElectronicDilettante]

Great video as always. Just a question, you stated that a cpu chipset can’t fail catastrophically at 1v. I was curious about the type of power a cpu requires to get so hot and came across a data sheet that indicates that pentium i5,7,9 use upwards of 140W@1.1V… that’s almost 140 amps. It even states this amperage on the data sheet. I’m still learning all this and that just sounds bonkers to me. Granted, it’s 1v but 140 amps?? Please explain… thanks

[@petartomic9783]

Yes. That is why you need a heatsink over and active fan.

[@fabian11235]

I am not 100% on this, I am still learning. But usually electrical components don't draw more amperage than they need. They got an internal resistance so its basic ohms law. The pch runs somewhere at 1V. There is simply only so much current that gets pushed through. So nowhere close to those 140A that would be available, only a fraction. At 19V its a different story the "pressure" of the Voltage forces much more current in than it can handle. The delicate internal circuits overheat and short out. Just some random numbers lets say the pch is 4 Ohms then at 1V you'd get 0.25 Amps so merely 0.25W. At 19V you suddenly get 4.75A which would be 90 Watts.

[@ariewijaya1679]

The pch get power from very simple buck converter like lm358. Not wonder it fry easily

[@oussamathedjfreeman]

Hi sorin that was good video, if you had a screen to test the laptop it will be good so the costumer will know if screen replacement will get the image back.

Hi Sorin, I expected that the first test after replacing chipset would be to try to start it without screen connected but with live usb and hdmi. I wonder why you cannot try live cs/usb or any other ssd with windows for the test?

[@twx8626]

Huge mistake if you try to run WIN PE on an open computer you will burn the processor instead!!! Especially that a heatsink must be installed + cooling paste + some of the heatsinks cool additional chips Some Asus laptops also some from other manufacturers have the same phenomenon. When you enter the bios, the processor runs at 60%-80%, a kind of internal test for the processor. You can monitor fans that work at high RPM... only after you have assembled the computer and placed it on legs at a height where there are ventilation openings from below... after that, run a test. It's fun. ...I'm running WinPE 11-10-8 Sergei Strelec :) on an SSD with ORICO packaging .ballistic missile ")
