Acer Nitro 5, working but not charging, motherbord repair, a strange fault

[@JustInspiredKent]

"No, the computer shop cannot do something like that." I can tell you with confidence that yes, some 'computer shops' round here can do something like that. I've seen it and MUUUUUCH worse. 🤣 Just wanted to add... today I fixed a backlight issue on a Lenovo laptop motherboard and it's mainly because of watching you all this time, I am able to do these things. Thank you Sorin.

[@maklogetrich2378]

@@JustInspiredKent yes they do sometimes 😅

"Sweet liquid damage", most times "cola", one of the key ingredients of cola is phosphoric acid. Phosphoric acid reacts aggressively with copper causing corrosion, in the case of circuit boards causes track damage. Also of note, phosphoric acid is a known "electrolyte" and can conduct current, that being said, a cola spill on a circuit board can create current pathways to components causing critical failures.

It is so refreshing to see someone actually repair a laptop motherboard instead of replacing it...We are constantly told to reduce, reuse, recycle except when it comes to the latest Mac or Windows based computer...You keep seeing faster CPU and memory performance, but I don't need to upgrade...My Dell D531 with its dual core CPU gives me all the speed I need to run Windows 10 successfully...The sad reality is computer manufacturers don't like us...They don't make money off of "old reliable" lasting a lifetime...So, they incorporate design flaws into all their models and make it really difficult to repair by gluing parts together...I guess people like us are considered old relics to this new world...

[@supergeekjay]

Yes, but machines like yours are only good for basic stuff. Office and web stuff. It is too old to run newer software, or anything strenuous. Try running video editing, gaming or even AI generation on it, it will be slow as treacle or not work, and as for 4K video, forget it! Dual core chips are so underpowered for today's stuff. My old Dell Precision M6600 was a beast when new (£1,400 desktop replacement workstation), but today it can't run anything stressful than just basic stuff, so I had to buy a new one. It's like asking a 70 year old human to do backflips and gymnastics. Old machines have their place, but to keep up and do the latest, you need newer. Sadly they are not as upgradeable as they used to be. Planned obsolescence, more profit.

[@jameysummers1577]

Yesterday I had an Acer Nitro 5 come in with the same problem and I had to take the board out of the laptop.It was running fine but not charging and it said it was charging. The first charging MOSFET caught fire as soon as I plugged it in to check what the laptop was taking. So, I fixed the PCB and replaced the MOSFET. All was well, and BOOM, the second charging MOSFET exploded when I went back to testing. So again, fixed the burned PCB and replaced the MOSFET and now were good. Sometimes the fault can jump up and bite you.

[@pauldery7875]

Excellent work Sorin. Another great video of diagnosing a fault on the motherboard. Paul, USA!

[@mihaiacer4395]

Visual inspection can save you a lot of your time

[@GregM]

A good reason why a visual inspection of the motherboard on BOTH sides is handy.

[@bones1225]

Nice job S.

[@CarlAlbermarle]

Sorin has Talent

[@joralexandrgoesdiniz8109]

I love when the proper calibrated wire appear🥰🥰🥰🥰🥰

[@Hidden_Hunger]

Sorin advantage is his experience + high end tools + rosin that's the secret.

[@retrocomputinggrotto]

dont forget the proper calibrated wire!

[@mrnikau1]

I stuck a screw right through my wifi card. Damn. Until then I didn't know this was a possibility.

[@aljosamlinaric8705]

you should buy strong switching power supply just for testing gaming laptops. Like Riden RD6012, crazy strong.

[@TheHalo14aus]

Exclusively for all the faulty Acer Nitro Gaming Notebooks haha

[@deamooz9810]

I didn't know that tracks can get corroded through the protective motherboard layer?

[@maklogetrich2378]

that track have a test point, so, very possible

[@ElektroTechNL]

Nice fix 😊

[@jurgenkruger3932]

If the battery does not get any electrons, it can be that it is fully charged. Also this first MOSFET can he broken. The charging controller can also be faulty.

[@northwestrepair]

Not all coils exist to be driven by any mosfets. Instead they are just filters.

[@electronicsrepairschool]

I think the word you are looking for, is 'inductor' :)

[@tkcomsiri7649]

good job sorin.

[@mikX4]

Was there other tracks with same damage beside those 2 tracks? Looked like it in the video

[@TriodeTetrode]

I was wondering same. There was one big track to the right which looked corroded as well. It's really hard to tell was it gone or not. Probably not since laptop seems to charge and work fine.

[@davutozturk3348]

Great job.

[@xeroeffect5745]

Sorin, you really had me believing I was live for a second! Who knew imaginary friends could ask such good questions?

[@ranjitmandal1612]

Amazing work 👏

Bună seara dl. Sorin. O întrebare mai "off topic" 😂... Cu ce ați acoperit bancul de lucru? Pare a fi o suprafață de cauciuc sau silicon... 🤔

[@ibo1973]

Hello, I watched many of your videos and learnt a lot, can you write the brand and model of the thermal camera you use. wish you success, good luck.

[@rfr653]

Good job mate 👏

[@TheBionicbone]

At last an Acer like mine with a side charge port. I've been watch for months. Has it got two SSD sockets... yes

[@technical5880]

thanks for sharing

[@PedroFNMartins]

Sorin you need to upgrade your power supply to a 10a

[@libyanboy94]

I believe he used to have a 3010 series with 10A, he switched and in one of his setup videos he stated that him using a 10A ps was a mistake for some reason.

[@youneslafri9120]

5a max power supply

[@thevideostudeo]

if there is a burnt pcb , something is drawing more current than normal, if that it not addressed can burn it again🙂

[@joaquinmatascuso9870]

nice video like always!

[@mihaioleniuc1642]

Very Nice! 😎

Hi. I have same laptop with that chip (now I waiting for delivery - need to replace that, why?), I looking for few problems, but on that I have short that pins on IC (desoldered and check), imposible on this point but stil short on that pins on IC.

[@joakoc.6235]

That board is not new, that board is actually old, is from 2019, I have that same model but on 15.6 inch screen, so mine is the same motherboard but it does not have the heat sink tunel on the right side of the laptop.

[@phambaonghiem9704]

I have a Acer Nitro 5 2021 version and i am worrying about the PCH chipset that reach 80 *C with only 1 USB connected, quickly above 85 *C when i connect keyboard and 2nd monitor, what should i do. Should i use only thermal pad or a small heatsink with thermal glue :< ?

[@F2x2]

3:03 - I guess : First mosfet !

[@TheBionicbone]

I'll just add this, mine discharges if left for a few days, the voltage in the battery falls until something disconnects it and the voltage goes up a bit. But its flat and shuts down after a few minutes without power. Not sure why

[@alwahch1000]

Easy peasy😅😅 you made it easy😂😂

[@biomagic8959]

you should open a school and educate a new generation of repair gurus 😎

[@PhoneReLife]

Hello brother please answer me i have a problem with my lenovo t450 14" the problem is the picture is flickering i checked the cable and it seems fine and i checked the voltage on screen inverter board v_out is 23.7 . Can you please tell me what do you think about this issue ❤

[@maklogetrich2378]

shouldn't the inverter voltage around 32V?

[@gabest4]

My comment got auto-removed. I just wanted to point out that there was a link in the brief datasheet to the real one.

[@gadgetmind]

Will that magnet wire be OK with the current? Short length, and dumping heat into tracks, but I'd have gone for bigger.

[@ANgeliC2k]

Most likely a dodgy computer repair shop can always do something worse. Like intentionally put water on the board so they can charge you with extra, or giving some technical reports to a customers who are not technically knowledgeable..

[@transformateur9969]

i have same problem with lenovo

[@samsscia]

You're lucky that you're surrounded by incompetent computer shops 🤑

[@IcecalGamer]

I'd say that That computer shop is highly competent. Knew exactly where to stop (before doing more damage) and hired a specialist: Sorin.

[@tobiasmangoma9566]

Sorin makes it look easy because of his experience.

[@TriodeTetrode]

@@tobiasmangoma9566 To be honest all computer shop needed to do in this case was to take motherboard out and have a proper visual inspection under the microscope. Computer shop probably don't even own microscope.

[@ДимитърАндонов-ъ7е]

@@TriodeTetrode what Sorindoes is like 1-5 % of repair shops. most of them just replace parts and clean+repaste the cpu/gpu.

[@TriodeTetrode]

@@ДимитърАндонов-ъ7е Yes I know. But someone had measured around that Intersil chip clearly so this shop seems to go more far. If it was this shop of course. But easy way to improve for computer shop, buy a microscope and do proper visual inspection.

[@KrissBartlett]

To me looked like the tracks were cut somehow corasion wouldent look like that ?

[@maklogetrich2378]

very possible, because that track have a test point also

[@SamiTM]

Ok so basically why a gaming laptop will not charge the battery is because a capacitor is missing from the motherboard. Aye aye... Mystery solved 😋

[@supergeekjay]

The customer could have scraped the board with the new battery when installing it. Even though the battery is not a customer replaceable part. Only the RAM and storage are, usually. Service manuals usually say the battery is Authorised Service only. AND a big no-no is they've used a cheap Chinese battery. Eurgh!! 😔

[@einfelder8262]

Some owners do not deserve a laptop - spilling stuff on the keyboard and not immediately cleaning it out, then change a battery for no reason, and screwing the case carelessly.

[@parawizard]

Skipped checking the repair traces? I would want to confirm that there wasn't any weird resistance values.
