"The power button is ok but its not powering on, maybe its upset.....could be..."
Thanks for the great laugh
You get good feedback not because you do dodgy repairs, you do cost effective ones with what you have got, and teach us about the circuits in the process. You simplify some very complex circuits. It is that reason why you get good feedback. Its the stuff you teach. :-) I hope you have a happy birthday, and enjoy your time off.
Make a video on my Asus a58c
@@unforgotenpromises I hate those motherboards. Small, thin, with a small D/C jack power supply port and built-in (can't remove) RAM memory and CPU. The built-in CPU always gets hot. If I remember correctly, there was something on a few asus modles like this that you can try. I'm assuming the problem is no power (won't turn on) or no display. You can try grounding the screw holes to the top chassis better. Around the screw holes is some light metal and if you notice where the TOP keyboard cover chassis touches the screw holes, it's suppose to provide some grounding for the whole unit. I used some tin foil pieces around each screw hole and then put it back together (applying some pressure) and I was surprised to see it come on. These boards are so cheap and sensitive to faults.
electronics free online course. I\'m not sure but ,if anyone else is searching for understanding electronics pdf try Letza Easy Electronics Lessons (should be on google have a look ) ? Ive heard some awesome things about it and my buddy got excellent success with it.
But he glues when he should epoxy. He hot glues broken hinges. He doesn't have very common parts on hand and does repairs that won't last 6 months.
Please can anyone tell me where I can buy
few broken laptops like this, I really want to
repair something and learn.
yes, customer bought and stole the wifi, then returned not working. simple
Sir, thank you for inspiring and for teaching me. From Poland, you recieve great thanks! :D
Thats great video sorin. We learned the 19 and 3.3, great lesson for the 5 volts rail.
Do you use zippo to find faulty smd with high temperature?..
Maybe the guys who bought it, didn't check that its internal connections were not plugged in.
cash converteers sold the laptop to a guy who stole the wifi card and took it back with ribbon cables unplugged ..basically he got a wifi card for free.
I remember Rossmann telling me that PCs are not practical to do board repair because they are too many models. I guess this guy proves him wrong.
Happy Birthday Sorin and good job.
I wish Sorin would tell me the name of the tape at 19:27
@@thingshappen9199 the tape is called thermal tape high heat resistant.
Nice Video too like your other one`s! Great work; greetings from Germany

Hi , I would like to know where you buy the mosfets.
And I have a mosfet with numbers FAD18AL. where I could find it. Thanks
Hello
Could you be able to tell us what tools, tape, liquids you use for your repairs in all videos in the time you use them ?
Thank You
... Electrical Tape, Mini Screw Driver, and Krazy Glue/Gorilla Glue.
A typical Romanian joke. ...maybe he's upset, he can be. We joked about everything.
My laptop not taking charge but working directly without battery,, what's the problem??? Plz sir
Positive feedback - well earned, I say. I enjoy your videos and the relaxed yet very practical and correct approach to solving real world problems. Have a nice, relaxing day off for your birthday and keep it up the good work.
Happy Belated Birthday Mr.Sorin. I need some information on how I can get my laptop to you so you can repair it for me? I've been watching your videos and I think you do a great job. My HP 15 Notebook won't come on the battery power works I changed the power board but still no power? Please help me out if you can....
I dont have the 3.3 volt on the power buttôn what i have to test
it feels so satisfying when repairing brought dead laptops back to life
Great lesson : the Fan was bad>fan_connector is getting too hot >Heat destroyed the power regulating chip>>> The same problem with my 7 yrs old Acer laptop..
Hi I am currently working on my laptop motherboard. After turn on it shuts down after 30sec. Where to look for the cause"
Happy birthday for Friday sorin
You are one HELL INSPIRON for us. 😆👍 Thank you. Cheers.
nice lesson thanks
Hi.Sorry for asking, what is your nationality?Thanks.Love your videos.
Thank you master
Bdw sorin is their any chance talking with you and help me with an acer. The usb data isn't working anymore . I only have 5v but no data,no mouse no camera everything is conmected on usb isn't working. Please if you can help me let me know. Wish you a nice day. Thank's . Andrei.
One more diagnostic tip for the fan......flick the blades with your tweezers to see if its bearings are gummed up.....
Thanks for the video. What was the liquid put on to see what was getting hot at 51:50? Did he say petrol?
Sorin I have a theory. Water damage on fan connector shorted 5v rail and caused damage to that chip and in the process fan die too.
Thanks for this awesome video
100% YOU RIGHT IF FAN NOT WORK FEEDBACK VOLTAGE TO DC TODC CONVERTOR
AND NO NEED TO CHANGE IO
Hello sir... U know... Lenevo X250 bios password remove how to please guide me sulotion

Hi, I have a HP laptop, and when I power up it just displays millions of coloured lines, even when connected through the VGA (same thing). What could be the problem? checked the ram, changed the screen and more but no results.
Because of you i managed to fix a Acer Laptop.......THANK YOU !!!!!!!!
Need help with an Asus A270-P motherboard. It’s not switching 12 volt ATX power on. 5 volt rail is showing 5.4 volts but only reading 1.7 volts at the chassis connector power on pin. Anyone know where to get a schematic for this board or has come across this problem before. Shorting the green wire to ground on the 24 pin atx power power supply connector starts fan spin.
Can you jumpstart a Dell Inspiron 17in M731R Laptop? It used to power up but every so often I would have to remove power cord and battery press and hold on button for 20sec put battery ba back in and power on again to start laptop. I replaced power ribbon because of damage but now it just wont power on. I like to salvage this laptop. There's always a way to make it work, it's just not my area of expertise. How do I test a motherboard?
Can u help me sir..i have aspire e5 575g..when pressing power key..it on and off immediately.
Hi, please I have a problem with the Acer laptop, the backlight, the laptop is showing in the background but the light 💡 is not light, so I have a dark screen 💻 I used another screen the same thing, What can I do?
Another brilliant faulting session , nothing dodgy about that, thank you , see you tomorrow .
Advanced Happy Birthday Sorin! More blessings and birthdays to come, and more videos as well. More Power to your channel! 16K subscribers and still counting...
Hi, I am watching your videos from Papua New Guinea and I like them very much. Plenty to learn and it has help me a lot in my wok. Thank you very much sir.
Just like me, the more you are thinking about something the bigger the vape clouds you produce haha. Thanks for the vids, they are really helping me level up my hardware skills and these kinds of step by step tutorials are not easy to find! You are a legend!
Lucky man. You found what you want... very nice job👏👏👏👏👏
Laptop's can P.O.S.T and still have --catastrophic or-- serious motherboard problems and be unusable. I've seen quite a few laptops (Intel i3, i5 and i7's / AMD & iMac's) boot up to the desktop but after 5-20 minutes turn off because of the onboard GPU / Video. Also, the worst of it is the iMac's and AMD/Intel motherboards that have ALL working compasitors and electronics, but the BIOS and/or circuit DATA (ROM) chips with DATA information that gets corrupted and/or wiped out (EMP / Static) and you scratching your head all day. Many times, after spending hours troubleshooting, I found that all the compasitors, resistors and power supply was working just fine but I had a corrupt or erased BIOS and/or I had a ROM chip with DATA somewhere that was corrupt or wiped out. This happened to me more than you would think.
The history of computer motherboards is ridiculous. Intel was making brand new motherboards (5 to 6 years behind what they already had because they wanted to sell off the "on-shelf product" they already produced before releasing the new stuff) that were faulty and had faulty components. In 2003 I had to figure out alot of "work-arounds" for so much faulty Intel motherboards that were working exactly the way they were made. Not to mention in 1999, Intel already produced and were sitting on Core 2 Quad CPU chips that remained on the shelf for 5 to 6 years before releasing them to the public. When you realize how many components are put together on a computer motherboard that have no idea about each other and how they are suppose to work together and/or communicate with each other, you realize it's just a catastrophe of chaos that simply work on and off together. It's crazy. Even ASUS motherboards had problems with this too. And the wireless wars between 2003-2013 were insanely ridiculous and even worse than the computer motherboards.
Happy birthday, Sorin. Sometimes you get lucky like this one. Take the win.
hey! how can i send me laptop to you for a repair? ;) Dell XPS 13 2 in1 9310, poss mobo issue?
I don't know if this guy even have the time to read comments ,however ,I have I was putting my PC back together , when I was about to put the internal battery back I saw that small light , I really wanna know if that's reparable and what is it exactly that stopped functionning. I it is the motherboard , right ?
Why do you solder the motherboard on the plastic case? You can deform plastic the bottom cover! Such a complex chip like EC controller needs first to be heated from down side with heater. If you solder only hot-air statition you risk demage chips or pcb delamination.
I'm sorry, but this is not a good example of how to do it.
so my laptop wont turn on at all. if i remove the battery and replace it. will my laptop possibly turn on ? also, im getting a new laptop with a 256gb ssd. i plan on replacing it with a 2tb ssd. both m.2. will it work just by doing the offline reboot with the os downloaded from Microsoft?
Question: Before you changed out the chip, wouldn't there be a pin that was connected to the switch so that you could verify the signal was getting to the chip before you changed it? You may have done it and I just missed it. I am just trying to learn, have you done a video on checking a desk top board? I bought 10 boards with bad cpu pin sockets and I am trying to replace them. I messed up the first 7 and am now trying to use them to learn and follow the traces from the beginning. How would you start trying to input power? Use a computer power supply and try to trace it. I have a antec power supply that does not turn on unless everything is good! The green and black bypass does not seem to help? Thanks for the videos.
real o.g. - fix device, sit back, hit vape. Haha.
thank you dear ! even if you r too busy , you r supplying knowledge . it is your profit ! [shaping mind ]
hi everyone ,if anyone else needs to find out about
electronic repair kit
try Saankramer Electronic Magazine System (should be on google have a look ) ? Ive heard some great things about it and my friend got cool results with it.
Hi sir,this is kogila anjaneyulu,sir you are videos is very very helpfull.i am requesting to u sir please when will i get problem with laptop mother board at the time i will contact with you,please help me sir.
i am curious to know if the ITE came preprogrammed or something ? everytime I see you replace the I/O chips you do not program it. please educate me about that. thank you
A great work but that ite chip is wasted or ı didnt understand that part.
Hi, I enjoy ur videos alot.. Please can you make a video on how to fix shorts from Smart TV Led strip without replacement and how to use DC supply to find short effectlively
I am from assam - india . Your video is very helpful for me ... love you sir
Sir, one question. Can we change a equivalent parameter value of a desktop mosfet into a laptop mosfet? All parameters are same but amp of desktop mosfet is 85amp and that of laptop mosfet is 13amp. Desk mosfet is sm3113n & lap is ao4712. Can we change with it please reply me sir....
i like the actual power testen deeper than power cord and button tutch shows most aint fried mother boards just simpler part change outs saven pc from trash sales tactic of "it wont come on cheaper to buy a new one "claimes ..sounds more like they didnt wana do actual repair and just wanted the faster higher priced sell but here shows fixes go simple and qwik
Thank you wish you was close by to fix mine
Do you buy faulty from cash converters ? Or has customer brought it in? My cash converters don't have anything like faulty for sale 😐
i feel buying a new motherboard is cheaper than the equipment needed to diagnose the problem. Can i pay you to fix my board?
Is that lighter fluid he's using to clean the board??
Please can anyone tell me where I can buy few broken laptops like this, I really want to repair something and learn.
I have a dell laptop and it has an issue. Sometimes it doesn't turn on at all. After doing the static electricity drain it turns on. When the battery is left in there is feint orange light and the battery drains overnight. When putting the battery in, the laptop automatically switches on as if the power button was pressed. When the laptop is off and the charger on pin is connected (but not plugged in the mains) the charger light comes on. It seems like it may be a short? Any idea what could be wrong?
if you don't have 51125 you can use 51123 it's same
both chip have 19 v on pin number 16
The only bad comments are from the laptop manufacturers losing business
Where can I buy programmed Startup chip , Please recommend an Ebay dealer to me ,
It’s normal for the fan not to spin when a laptop cold starts. When the laptop slowly warms up. Then the fans will start spinning.
can you make a video about how to turn on laptop's motherboard by joining positive and negative of laptop batteries which are out of battery case
I am very impressed by your different maintenance activities to enable others motivated .Good job sir .keep it up
where you can find laptops like that,with problems (acer)to buy?
hi sir can you help me i have asus x552m i check on connector i have 19v but on first mosfet i have 19volt on one side other side 0 volt lose all volts on first mosfet and i think is second mosfet dead because multimeter give me short circuit connection too small mosfet m0930m i check again with no power adapter on diode mod all mosfets give me 460 500 volts this second mosfet give me 7.3 volts and 7.3 ohm all other have 100, 56 , 170 ohm my laptop is total dead no power no lights
I know this is an old video, but thank you so much for all the knowledge!! All your videos are amazing. Keep up the good work!!
Thanks man, people still keep old laptop and fix them right. Put ssd and it's fast enough for most people e
Sorine nu era mai bine daca verificai mi intai linile de 5v de ram,cpu,gpu,cipset daca erau in scurt si dupa aia super i/o chipul,cred ca startup chip original era bun si nu trebuia schimbat.Tineo tot asa cu stima YO2MFU
your hands are magic most of dead laptops works itself after touching your hand
was not the original solder difficult top melt ? (I heard of solder for machines that contains copper and ask high temperature ). I see yuou use Zippo fluid, here I have mineral spirit, that also evaporates very fast I guess it can do the same work (min.sdpirit type F ort C)
41:07 What pins do you short to power it on without the button? I have a separate board with a button, which is connected to the motherboard with a ribbon. There's a whole bunch of wires in it, because there are also some LEDs on the panel with the button. So I'm not sure which ones should I short, and unfortunately I can't simply test it with my multimeter because the probes are too thick for the wires on the ribbon :q
Maybe usb killer? No 5v, fan fucked up, and also the super i/o chip
