Asus S200E , dead, motherboard repair

[@fabriziovicari7565]

It was exactly that mosfet! the first one! You have saved my computer! thank you so much!

[@electronicsrepairschool]

u r welcome :)

[@franciscomorais4179]

You are a great man because you share your knowledge but more importantly you worry. I'm learning a lot from you.

[@thetiredtechie2704]

I'm so happy when I see there's a new video :) It's like Christmas :) Tanja L.

[@eileenluck1176]

Have followed your brilliant video and laptop up and running - thanks

[@fsimoris]

Good work 👍! Thank's a lot. I'have a problem with same PC, the voltage is good, but i think there's a short with many capacitors! What should I do! Thank's in advance. 🙏🤗🤗

[@SOS.ProRepair]

Je m'ennuie jamais de vos videos je suis un grand fan de vous qui vous suit du Maroc ^^

[@SteXist]

This must be weird. But, I see that your GoPro cam blinks whenever you use Power supply probes to check Voltage on a board. it takes about 15 to 20 sec to freeze. Thats why your hands with probes are always on the frozen screen. I think that the Gopro or the power supply need an independent power socket. That happens because they seem to share the same power supply source. Im a bug fan by the way, but not a 7 min guy. if you see what I mean. keep up the good work. you are a repair Sensei. I wait for your new Vids everyday. I Like the Laugh sound you make when you fix something. hhhh Congrats from Morocco

[@Kipster848]

You amaze me with your technics

[@morphuk1]

Thanks so much for your very educational videos. Can i ask which pins you bridged on the Mosfet and also you mentioned the startup chip and I wondered there was an official name for it so I can look it up and read some mote about it. Many thanks, you're a lifesaver!

[@galkaenazul]

Thank You Very much! Saved my laptop.

[@electronicsrepairschool]

u r welcome :)

[@alizoghi7457]

Thanks a lot.Do you repair other boards like ECU?If possible, include an instructional video of repairing it.

[@saarike]

Nice as always. I hope that you do more videos about motherboards.

[@electronicsrepairschool]

i will, thank you

[@baya24]

...like to remember that i saw that kind of circuit here and can be NOW sure i common problem on this ones...

[@recommendedforyou157]

can someone explain why in 6:43 the drain and source is shorted

[@vanguardspider]

Thanks for the great video . I have an Asus X504U laptop, it's dead . The first mosfet lined after power plug doesn't give voltage on one side. I removed it , shorted it , when shorting it gives a spark , even after shorting it with solder , now the plug doesn't give any voltage . Another thing , i couldn't find bios bin file that match the size (1024 kb) , only 8mb ! Any help sir ? Thanks in advance.

[@richardwilliams8412]

So happy you made this video. A friend recently gave me his damaged laptop same name and model. It is totaly dead he has bought a replacement power supply 19 volt but at 4.75 amp instead of 1.75 amp. do you think it will be worth my while to use a lower amp charger and follow tips in your repair video or is 4.75 amps ok . Thank you in advance for advice.

[@pedrofilipeserra1582]

you can use even a 20 AMP (if existed) if the mainboard ask for 1,75 it will use 1,75. never use a 19v power supply with lower amperage. it will burn the power supply

[@agussalimbasri9136]

if im not mistaken, you just remove the mosfet without replacing it?..am i right?

[@camnascar]

I, good job! But i have the same laptop model an S200e power on but with ac adapter plugged in, the battery not charge (battery good), and when the battery is very low the laptop turn off and don't turn on also with the acadapter,need to recharge battery if i wont turn on! Any solution?? Thanks

[@pedrofilipeserra1582]

verify the charger IC

[@patoverde]

I love your channel!

[@xose1984]

that was so good, you explain how to follow the 19v power rail, but how do you know with was the bios chip? do more videos with how to follow the power rails, thank you for sharing your wisdom with us!!!

[@electronicsrepairschool]

Ok, i will

[@Infiniti25]

xose1984 it is a small black chip with 8 pins, sometimes it's close to the bios battery. On some motherboards the bios chip has a white silkscreen behind it and often has a plastic covering material to prevent shorts. If you are probing voltage with multimeter you should find 3-3.3v on one of the corner pins as you saw in this video.

[@faresshaker7765]

Thank you , if the problem was in the second mosfet would it be different approach because in a previous video you had put the power supply in the mosfet to find the short

[@electronicsrepairschool]

Those mosfets are in serial mode on 19v power rail, so if are in short the laptop will should be working fine. The mosfets from swithcing power supply, yes, if they are in short you can find the quickly with the bench power supply.

[@tanishqbhaiji103]

It’s freezing because the power adapter doesn’t have enough holdup time so the power supply is unstable , adding some bulk capacitors should fix it

[@ningdeloy6342]

nice video sir again

[@siddiquishoaib7929]

i want your video daily.

[@frantisekhorvath3078]

Thanks for video just fixed one motherboard

[@bahadoromid3554]

Excellent. Thank you

[@syambagaming9718]

Sir I need your help I have a laptop asus X553m series when i turn on my laptop the power immediately gets on and off and i upadated its bios too but still problems persists....... From India

[@rahularora4155]

hello sir,is there no need of changing that switch

[@glazyrap9244]

i have same problem, i made same bridg at mosfet , i have all alw voltage now, but still no power on lol

[@rashh77]

Thank you, but you just remove the mosfet, why you didn't replace it with another one? please reply.

[@nelsony4024]

Thank you Sir this video.. i have the same unit to repair problem is the board is shorted en mboard is tampered customer said he sent to asus service center but still not repair,,i have check all caps en mosfet the i remove one mosfet switch as you did yes there is 19v..but still shorted.. help pls..

[@Marko_Djuricic]

Because the mosfet was not the problem. It switched off because there is short somewhere after that mosfet.. I don't know why he guessed that that mosfet was faulty.. Maybe he checked with the power supply before starting the video.. It's not the case with your motherboard as you can see.. or you soldered the gate and the drain together

[@businesswoofer]

man i got a acer aspire and it doesnt charge boot up or does anything it just makes a click noise in the motherboard when i plug the charger

[@seagorman]

Hi Soren , any particular reason why manufacturers use 2 mosfets, would one not be adequate enough

[@electronicsrepairschool]

i think the first one its for protection against inverse polarity

[@seagorman]

Many thanks Soren for your usual speedy reply

[@diegoandradecaruaru]

How often do you find boards that have problems in their Embedded Controllers? Do you have a programmer for those chips or you buy them already programmed or take them from other dead boards?

[@electronicsrepairschool]

they are not dying, just get frozen as they are always on even if the laptop its off or has a dead battery

[@gused1128]

great works for me , thanks

[@franciscomorais4179]

It can not be OBS?

[@TerenceAng]

Good job.

[@rahularora4155]

pls help me sir is there no meed of putting new switch?

[@rahularora4155]

need*

[@jeramsadventuretv4905]

Very nice!

[@aneezaliyar1901]

Its a real quick one. I was like- 10 mins...? are u kidding me?.. But you look so serious, so bold in this video. Where is your charm..? We want that laughing when u fix something.. We want that sarcastic comments when u find something funny.. We want that frustrated murmurings when u r confused... Really missed Mr. Sorin in this video...😒

[@quattro4lifet844]

[@josephcauchi5371]

How can I confirm it's the graphic chip

[@electronicsrepairschool]

check online by laptop model no

[@indio502]

mmm non sostituisci mai i mosfet? never replace mosfet?

[@rinoroma]

come ha fatto a vedere che è rotto? è un interruttore elettronico, se non gli dai 5v all' input, non si chiudono le due parti, che cavolo di riparatore è

[@ridariyad]

nice work you are help me for répaire my pc

[@rmitkumar7564]

[@Marko_Djuricic]

Short happens

[@lucio3285]

Mahusay!

[@Biffo1262]

Change the micro sd card on your GoPro. If that doesn't solve it then update the firmware.

[@Infiniti25]

Steven Booth he said it was on latest software...I take that to mean he has the firmware up to date.

[@hadireg]

👍👍

[@ericramzi5445]

the software of the Go -pro need to be Re-update

[@jakwongaurbain8178]

Hullo! help me please! i have Asus laptop unfortunate it had stopped working completely! what might be the problem? from Africa DR.congo.

I'M INFINITELY GRATEFUL & THANKFUL FOR ALL YPUR EXPERIENCES + YOUR VIDEO TUTORIALS MY ILYCABSAFEMWQGKGAPTESPF OR INFINITELY YOUTHFUL CONSCIOUSNESS HAVING A TEMPORARY HUMAN EXPERIENCE MY BROTHER ELECTRONICS GUY. I THINK THAT ALL THESE LATESTS MODELS ARE DONE AS CHEAPLY AS THESE LAPTOPS, BC THEIR MAIN FUNCTION IS TO SPY ON YOU, LIVE FEED DIRECTLY INTO THE NSA DATANASE. SO ALL THESE LATESTS MODELS ARE DONE CHEAPLY IN CHINA WITH CHEAP PARTS THAT ARE NOT MEANT TO LAST EVEN A FEW MONTHS, ACCORDING TO THE "WIRED" MAGAZINE, LOL.+ PLUS WHOEVER SOLD YOU THAT ASUS MODEL TV SCREEN PROBABLY DISABLED SOMETHING TO GIVE YOU A HARD TIME BC THEY'RE JEALOUS, LOL. MAYNE YOU SHOULD TAKE IT APART + FIX IT. MOST LIKELY THE MAIN REASON IN ADDITION TO BEING MADE CHEAPLY IN CHINA BC IT'S CHEAP LABOR IS THAT IT'S MAIN FUNCTION IS TO SPY ON YOU, WHICH PROBABLY BURNED IT'S CIRCUITS AS IT WAS VIDEO RECORDING YOU LIVE TO NSA+ THE CAPACITOR WAS LOOSE+ BURNED OUT, LOL.

[@geoepi321975]
