How a hard laptop repair looks like - Acer laptop not charging, motherboard repair

[@carlodevinventiis1737]

Sorin,you are a real Master.For normal techician this is a Classic no repair case.

[@malikkhan_01]

Thank you very much once again. And am really grateful mostly about the recent videos, because they have really helped me to learn more intel about the BQ Chips and their involvement in charging the system battery. And I can't stop myself from being more grateful for ALL your videos, because I remember when I started to watch your videos like the previous year around August, i literally knew nothing about laptop PCBA ... I used to look at it as a green thing with many tiny components. But now I am glad I can understand some few things, because of your videos. I really want you to stay longer, and keep on uploading those videos because they are so helpful.

[@eliasbourozrrrs8585]

Greetings from Elias Greece.Very clever troubleshooting.

[@68pishta68]

wow, amazing diagnostics! I picked up a no power ACER and will look at this vid for guidance.

[@laidman2007]

What a challenge! I enjoyed every minute of the process. Well done! Thank you!

[@renecastanos949]

Wow! I have learned something new again! Thanks for your effort and priceless contribution sir!

[@malikkhan_01]

And I wish KZbin had a double like feature, because some of your videos really deserves two or three thumbs up.

[@SuperfixrN]

45:29 that smile :) yaaay good job! I was thinking maybe it has a battery circuit killerswitch on backcover as that usually is a acer thing.

[@ravindraadapa2952]

For learning it's a good video on how to track and find faults

[@dulerock90]

Sorin, you can charge this battery with NLBA but, when you press charging, you must wait 20, 30 second and current will go up. I do this many times, just wait a little longer for it to start charging. Balance is not important fr charging

[@wigmansir]

Great video i have a laptop with similar problem it just won't charge the battery, changed the bq chip but nothing changed hopefully this video will help me solve this issue in facing.

[@carleckhardt4701]

Really enjoyed watching you troubleshoot this one and I learned a lot from this thank you.

[@Soloptech]

I really appreciate your time sir and the way explain, i have learn alot from you.

[@anthonyvisagie7106]

Incredible well done Sorin

[@LOGICONE-q5c]

Thank you so much Sorin! you are an amazing teacher and am grateful that every day I learn new things from your videos. I would like to ask if there another cheaper alternative to this battery and good linear power supply. Am from Rwanda-Africa Thank you

[@photoexpert3771]

I realy appreciate the time and effort that you put into making these invaluable videos, but i still prefer and miss your un edited versions i.e real time videos. I miss your banter whilst you are finding and fixing faults and also its gives us a true idea of how long these repairs ACTUALY take. Thanks again.

[@computersrepaircotesaint-l7407]

Yeh me too. we enjoy every minute

[@David55436]

When the video is unedited I can learn much more about the way to find the fault, I also prefer unedited videos

You are so awesome and amazing and genius.....😊

[@ronlevin2339]

On macbooks you cannot change mosfets like this, CDC3215 and 17 cannot be exchanged although they are basically the same

[@jaym5938]

Another nice laptop! Still waiting for Sorin to say, "This is not a nice laptop...trust me!" lol

[@windycl111]

I love your videos!

[@fichambawelby2632]

Thanks once again for sharing your knowledge, Sorin. I have a question for you: do you think I can buy the Romanian NIP Embedded battery analyzer?. I'm in Madrid, Spain. There are too many times I saw you using it, and I find it extremely useful. TIA for your help.

[@Swenser]

Need to be careful when using generic adapter. Sizes of centre pin sometims off by a bit. Thus laptop did not come on first time. A nudge further and ok

[@maklogetrich2378]

the problem is from rusted track on BQ chip

[@simranshaikh5485]

You are Genius ✨️

[@Mobile.Repair.Technician786]

I have a question for this laptop battery analyzer. Does it have to be renewed annually?

[@reversetransistor4129]

Hello, capacitor gangster, lol, I didn't saw you measuring the gate of the replaced MOSFET, replace burned track and measured drain-source. Just to be sure that you have a higher resistance and not damage the MOSFET again.

[@christozed]

@10:00 Yeah because the battery it's unplugged for a long time. I told u so many time you have to wait

[@notJW13383]

Another great and interesting video!

[@temp8420]

Great repair - thanks

[@trilhosdoalgarvebtt]

had this problem recently, shorted mosfet on the battery circuit 😂

[@balik.electroservice]

Terima kasih banyak pak .. 🙏

[@kuripotech461]

Sir I have similar issue just like this. I have Dell Inspiron laptop in which if I connect the battery the laptop goes on, but if I connect the charger with the battery on, the charger light dies and it is not giving 19volts. But if the battery is out the laptop powers on with just the charger plugged in. What could be the issue here sir? Thanks.

[@pierrotlebatisseur9308]

Where did you get the replacement MOSFET, from a donor board? If you don't have donor board is it feasible to purchase them online ?

[@mindezz]

i have same exact issue.. replaced charging port, battery and addapter still battery sits on 2% without progress.. my question is how much does this kind of repair cost?

[@franciscohernandez1830]

Hello, I have a question, my laptop got some water on it and I tested this Parr not working. The part on the top have this numbers 820 NO3 CMI 0295 they look like mofset do you now where I can get the part?

"We have a niiiice one, really nice laptop, this ones a customer job *bubbles the vape* HA Ha! That's crazzyyy lawl!" - Sorin Love the videos, always an interesting video from you Sorin!

[@ChrisJR1000]

Hey my laptop needs BQ 24780S ic chip replacement for my dell inspiron 7577 my laptop currently doesn't turn on the ic currently on looks damaged. My question is can I buy any BQ 24780S chip because i keep seeing difference in the rest of the number specification when i search for it on eBay and Aliexpress. For example the chip which is on my laptop is BQ 24780S TI something "can't clearly see the rest of the numbers" and CQ something "can't clearly see the rest of the numbers" but when i search for the Chip as BQ 24780S , there is BQ 24780S TI 540 C4TR also BQ 24780S TI 561 C4NN and other types. Can i buy any of these two and will it work as long as it is a BQ 24780S ?

[@lazytest3421]

Thank you for your videos. I want to start learning Electronics, can you please advice what type of tools and material will I need as a beginner.

[@miftosaurus]

two 830-grade multimeters*, a regulated power supply, a linear one, if you can get one, something like 20-25V/5A max, is ok, and a 60-70W soldering iron. table chair, a lamp... at least, some magnifying glasses, after a while, a microscope... and an laptop able to read pdf's and browse da internetz for datasheets, schematics and videos like this. * because sometime you want to check voltage and current same time, and sometime, the power supply ammeter is not sensible enough, or even it don't have one (like "laptop bricks"). also, as a newbie, is expected to do a lot of mistakes, so, if you fry one, you can try to repair the other one... after you buy another 830. they are cheap and decent enough! good luck. :)

Domnu Sorin aveti ceva videouri despre reparatii Hybrid Inverters pt solar? PS. Mi-e dor de videourile despre helium ,ce vremuri acelea.:)

[@andrasszenteszki3950]

That was nice.

[@joemamabidendementia]

amazing.

[@Edge-71]

Hey Sorin Is your charger cable connected directly to you power supply, did you cut off the connector ? Thanks man

[@Knebebelmeyer]

slowly Sorin went crazy.... A wire?? its a proper calibrated fuse and not just a wire^^

[@_kicaBo_]

Bravo.

[@YoutubeSupportServices]

47:36 So.....ummm?, Is that "1 hour and a half" in the UK-time scale, which I believe converts to approximately; "6 hours USTime.. It's a rough estimate... I mean; It's kinda hard to accurately convert a "UK-Hour" due to the extra minutes per UKhour for " tea, a snack, more tea, a little TV, and some tea)". or did you already convert a "10-minutes UK" job to the "1 hour USTime"? 😁

[@roche1237]

Thanks Sorin this was tuff we l earn

[@antoniodias2776]

Excelente.

[@kristyalberton9498]

My battery pops out without taking it apart. I think I will have the charging port replaced instead of buying new.

[@경험공유]

I don't understand well why your laptop is suddenly a live in 9:50 10:50 😅

[@andyvitz]

No, not that weird cause an Acer computer will not work. If the battery is not installed, try the battery he Letty had in it. He probably modified it
