Acer Laptop motherboard repair - Not that easy this time

[@miguelferreira1051]

I have seen more than 50 videos, I have never posted any comments...I'm an industrial electric technician, with some love for laptop repairs... Even with schematics is hard sometimes, and this is incredible...doing it like he does, teaching with no secrets like he does...You have win my greatest and honest respect Mr. Sorin... Regards, From Portugal!

[@roseelectronics4582]

You've found the right channel to learn laptop repairs, sir. Sorin is among the top 2 on YT in my opinion. The other one is Laptex. Have a look at their channel. Most of their videos are in Hindi but still there's handful of English videos which I found very helpful. I don't have any affiliation with their channel. Just wanted to help someone who's willing to learn laptop repairs.

[@juliusvalentinas]

@@roseelectronics4582 NOn english channel? What. What usefulness is that?

[@roseelectronics4582]

@@juliusvalentinas ask a German, Japanese, or Chinese guy they'll explain. In Japan, they rarely use English, not even in design phase. English is not the language of technology, but mathematics is.

When Master Sorin says : " Can´t believe I spent an hour " , means I would be happy to find it in a week.

it is like watching a movie where sorin takes the role of a detective and starts Interrogating the components until he finds the suspect xD great video sorin and thanks for sharing :)

The only difference, that on Columbo we (the audience) already knew the offender and we were just curious to find out how the detective found a way to prove!

Three boards diagnosed. One repaired. About 25 minutes per board. Extremely fast! A very informative video. Thank you.

Ďakujeme.

[@adriansilvers2079]

Just gotta say, "Sorin", your video's are "Sic". Trying to learn about fixing stuff and came across you channel about 6 months ago, I've watched everything I can find. Always look for the two mosfets, coil and current resistor now....;-) Please keep doing the long video's, please keep showing the mistakes, please keep explaining. It helps us newbie's enormously... I love the "dodgy" fixes, but once you understand why, they're good. Thanks for taking the time.

[@trlababalan1586]

Takes you half an hour to figure out that you don't have the ground?! Bravo Sorin you are a genious!!!

[@michaelparanormal]

Thats why we like watching you repair theses laptops , your so dedicated and wont give up like most of us would!

[@tony42hajdu]

well, we love Your long videos Sorin, each minute spent watching your videos is worth it, and funny too :)

[@protonx80]

i cant believe your skills with the soldering of high pin count ic's .. ive seen others remove the ICs and clean the pads and apply solder to those pads and then try to solder it .. ive never seen you use extra solder .. and as much as ive seen your videos (and i ve seen many .. most ) youve had a perfectly soldered IC every time .. this super IO was an odd one .. and even though twice or thrice .. it moved from its place .. it was soldered perfectly.... my salute to you sir ... ive learnt a lot from your channel .. and to think .. im not even in to the repair business .. i used to assemble and deal in computers long long back 1994 to 1997 (fresh out of college) so thats a long time back .. but thank you i watch almost all your videos

[@gorky_vk]

watching him replacing these ICs without any problem look strange even for us who often work same kind of things. Pure science fiction :)

Hi Sorin, it have been a long video, and you fixed it, and we learnt something 👍🇦🇺❤️

[@sipansibabdreddknot5179]

hi sorin ive been watching your videos lately and for the past years and never gotten to focus up until now, growing up i use to love electronics and repairing things, thou with life hardships growing up and no one to educate and mentor me when i was a lil boi ive never pick up on it, but 32 years now watching you decided to pick it up again and upgrade my self to learn and grow, i bought myself some soldering tools and now learning new things from youtube and your channel, theres a long way to go and thanks alot take care

[@Falvien]

My bows to You! I'll quote Tina Turner: You're simply The Best! Always a pleasure of watching You at work and thanks for this precious lesson. Hello and see You soon from Poland.

[@thomaskane9922]

What I love about your channel - you teach people how to think. More thinking - the less stupid people doing bad things.

[@thekillerdog5228]

You are like the friend i wish i had, ive learned so much watching your videos and now i only ever fail if parts cant be purchased/mixed or swaped. Also the obvious damage inbetween layers. I use a rework station for small stuff and a old counter stove 200c for reflows works like a dream :D and old style solder irons for stubborn places 🙂

[@breakingthe4thwall260]

now that's a thoughtful customer the kind i like.

[@ATAG-yn5pd]

@electronicsrepairschool i've learnt so much from you (lol), after the diagnose i thought it must be a faulty bios, or a partially dead controller (IO)... and when you've said the same around 1:00:00 i was so fckn smiling and being proud :D Thank YOU!

[@lagging_barish3736]

13:25 why can't you fix it if it's a ram problem? You have 3 boards to replace the ram. I don't get it.

Sorin I hope you find one day the time.. to do it al the way and not in a hurry. I understand you have a shop to run. But I almost see you make two boards in one time but you don’t did it. I like your spirit too always thinking off the shop. Thanks for all the time

@Sorin, easy way to check SOC (system on chip) (CPU) test data pins of USB ports if one data pin is shorted cpu is dead takes 2min to diagnose, saves time

[@SinsBird]

@@multiomer1997 Read again and find out

[@AnonymousRepair]

USB 2.0 has 4pins (VCC) (D-) (D+) (GND) Test D- & D+ to ground you can do the same with USB 3.0, the (PCH) is build into the GPU

[@awetaiwo9551]

@@AnonymousRepair I need more explanation on this pls

[@AnonymousRepair]

@@awetaiwo9551 SOC is CPU and PCH rolled into one chip, if the data pins are shorted it means that the SOC is dead as the USB ports are connected strait to the SOC

Sorin, I have been enjoying your videos. Thanks for your instructive, practical style 👍. I have one criticism. PLZ mention the make/model of the computer you work upon. If not in the title, then maybe tag it, or mention it in the explanation below video. This way all the people who are looking for guidance on repair of a specific laptop can find it in the Search function.

[@samgibson100]

you are the man Sorin.

[@muhammadmashaly1299]

Thank you Sorin i learnt so much

[@JazzEnso]

Most of the time the difficult job to fix is missing voltage, you're lucky sorin because you have 2 pc's extra board to get a SIO ,if you don't have a same board or SIO, you can't fix that! BTW is a nice video and great idea, thanks man

[@COMPUTERREPAIRSCHOOL]

hi sorin. on battery the coils will not gen voltage.the chip releases a 100ma low output to the super io .and after the power button is triggered the mail 3v & 5v will get power love from sl

[@tinkmarshino]

bad for business great for us.. Sorry Sorin.. But thanks! I just had a thought at the end.. If the customers could see you working on there lap tops, fixed or no, they would be satisfied you did your best.. I truly appreciate people who do there best.. no matter at what level it is..

I ask why did the customer made it so difficult by not sending the charger ! Also whoever sent this does know an awful lot about these laptops to have two other motherboards ?

Can anyone point me the direction of fixing my laptop ? I have replaced the Thermal Paste on it and accidentally blew my Screen Backlight Fuse off. After finding the blown fuse and removed it + short the circuit to see if the issue is still there... the screen is working fine... but now the Battery does not charge anymore. The laptop seems to be working fine only when plugged in ... but dies immediatelly when I disconnect the charger... which means that the battery is not charging. I have removed the battery and tried it out in my new laptop (they both have the same battery model) ... I have charged the battery ... but when I try now to connect the charger... the charger's protection kicks off and cutts the charging power. I have tested the battery from my new laptop as well... and the charger cutts of the power as soon as I plug it in. Any advice on where should I start ? Thanks in advance
