As i've said on many occasions before Sorin, the best Laptop tutorial channel on youtube, keep up the great work
Thanks Sorin! This has been 1 of your best videos. That stuff is critical for better understanding of your work. Hopefully I will be at your level someday. :) .
Thanks and I really value your Electronics Repair School. I try to attend a lesson a day! Consequently, the world of computers is starting to make sense, so cheers for sharing your expertise and in-depth knowledge. Delivering lessons in 'Live time' is great! refreshing and authentic.
Thanks a lot for this video. Its so beautiful to find this kind of people, giving away specfic technical knowledge in these days. You helped me made a repair today wich would had taken a lot more time if I didnt have this info. Im so grateful! Will suscribe and keep learning.
The Volts adjusted in proportion with the I ,as to keep the Power constant.
You are the BEST TEACHER of electronics, THANK YOU!
True!!!
Very good and expressive presentation. Thank you.
Yaah we understand its not possible to answer all email and comments, but at the end of d video we r getting many thing from u. which gr8ness of u. Thnax ton u r sharing ur huge expreience with us.
This was a very educational video, Sorin! Really demonstrated and explained the concepts well. I will now always look for stronger chargers so they can work more "relaxed" like you said. : ) Thank you!
best lecture and u are a wonderful teacher
nice to see you when you give information
16:19 Great lesson and I agree! You have many successful repair videos of consumer devices with a variety of issues, but the critical application of the key concepts are what I believe you're trying to emphasise. That's what I believe separates the "technician" from the simplified "top-level component swapper."
You are the best, thanks for sharing your knowledge
you are awesome, thank you for sharing your wisdom and knowledge.
Good and useful experiment!
Hallo Danke für deine anschauliche Erklärung !!!!
great video you are amazing everything explain and with actual test thanks for the videos keep more video lessons about dead motherboard
Thanks sorin sir for your inputs and knowledge
Great Video as always. Thanks
nice learn bro ...good job
thank you sir, for you're sharing your knowledge!
thank you sir,awesome explanation.this is imperfect..
Thanks for video.i think my gateway m series fried today when I plugged in 30volts and charging cord got hot and smelled burnt.did I ruin laptop? It won't power on
This is so much info. Thanks a lot
very well explained Sorin
you are very good teacher i respect you for that . kindly also explain the instrument you use and we should also should buy that will be very kind you i mean hi tech one
thank you for your videos very informative
Thank you. Important information.
Could you please make a video of how to use the equipment that you use....its just hard to make out when and on what components of motherboard do we use what amps to pinpoint the faulty components
This is good to know. I have an universal charger that allows a setting from 15 v to 24 v, and I have been very worried about accidentally over volting laptops I check because I didn't set the output first. It's nice to know I won't fry a motherboard because I checked the laptop with a different voltage than specified.
Hi, could you please describe the internal individual power supply units in the laptops?. As examples, the +5 , +3.3,-12.... etc.
Thanks for all that practice explanations.
I was hoping you put 240 AC into the laptop to see a nice explosion. Good demo. Thank you.
Sorin, thank you so much for the detailed explanation. Do you think it's safe to connect 2x 12v car batteries or 12v adapters/power supplies in series 24v and power a laptop regularly? :)
I think it would not be good for your computer..
BTW you can connect use only one battery and a power booster
Nice Video Sorin. I guess using the higher current charger may just mean if there is a failire internally in the laptop that it would be more catastrophic and easier to find!
Probably not, because the adapter's over-current protection will kick in and it will shut itself off, but i love the way you're thinking! 😆🔥
Hello I would like to know if the power supply is 2A is enough to test and repair phones?
Thank you Sorin, like it says on the tin. you can't get out more then you put in!
Great help thank you sir ( sorry I don't know your name) , but you have a very good way to simplify things and explain complicated processes
I am looking to get my first power supply , and I looked at the one you recommended from CSI Linear one but it is over my budget for now , and I am not sure I need a 50/60 Vault one , they have a cheaper one which is Linear 30vaults /5Amp or 10Amps version , plus for the same price they have the switch mode type,
But I remember you vaguely saying Linear is better then switch mode type !!!
I am hoping you could make a video or point me to one you have done already in which you explain your preference and reasons behind why Linear over Switch mode , I realise your very busy and may not have time to answer me personally , but a video would be very helpful for all us novices just starting out , many thanks 🙏
his name is sorin
Thank you
0-30v 0-5amps its ok, i never use the power supply over 5 amps anyway. Linear one!!!
Electronics repair school thank you Sorin
Hi Sorin, this question might come very late, but I'm wondering why a Linear power supply is needed and not a switching one?
Where can i get an heater like yours? (To desolder parts) i got a laptop heavily water damaged and i wanna try to repair it myself.. What do i need? Lippo fluid/propyl alcohol, liquid flux, the heater?
Keep them coming dude ;-)
Could you, or have you done a video for a dc to dc boost converter to charge a laptop from a 12v deep-cycle battery instead of using a 120v plug in charger? I was hoping to do something like that in my camper van instead of using the battery to power an inverter (up to 120v) and then use the charger to turn it back down to around 18.5 volt dc, 3.5A, which seems very inefficient.... Thank you for all the videos you do!!
nice vid bro
Hi Sorin thanks for another great video. I don't own a Linear dc power supply yet so i couldn't test. But i would like to know when you try to find bad component, do you lower the voltage to get higher amps, or you can make it at 19v and making the amps higher??
i will explain that on the next video with a short mothrboard
Awesome!! Thanks Sorin!
I would buy a shirt from you that says This is Crazy. I like when you say that when the Gopro locks up. You should send these videos to GoPro they will probably send you a free camera. Keep up the good work.
Hi there ,its was very very very use fullllllll viiiiideoooooo,thanks
sir in dead laptop how much volt n amp do you give, to find short mosfet or capacitor?
19v 2-3 amps
Its a pity we don.t see more PC motherboard repair
thanks :) nice videos
On new models this is not working. I did try this with my laptop a toshiba P70-B. If I input more than 19v will not charge and will not have the power in led on with battery out. Also when is on with the battery in will take 6.32A without anything attached to usb. The label on the laptop says 6.32A. If I attach a phone or anything on usb or run the cd will still take 6.32A. So newer laptops are build different. Also if I input less than 6.32A will say plugged in not charging but when I have 6.32A on input will charge fine
You're confusing labels with actual live values. Yes, your laptop is very power hungry and it wants a high quality charger that is actually capable of providing the power stated on its label (the charger), but that doesn't mean that the laptop is in fact constantly using 6.32A. If you want to check that for yourself, you can buy a household energy meter (watt meter) and plug the laptop power adapter in it. Then you'll be able to at least see live data of your adapter's consumption and you'll sure notice everchanging values. If you want to monitor only the laptop's consumption at constant +19V DC, you'll need to modify your original adapter or use a lab power supply like the one in Sorin's video demonstration ;)
now i'm using a cordless power tool battery with 20v rating on my laptop with depleted battery, and it's working fine
So is it safe to say that any laptop charger (which fits F-M) will work since the power suppy will always regulate what the laptop takes? I'm always cautious when puting a HP charger in and ASUS laptop
Exactly!!! You can use any charger on any laptop
Yeah...in this case the bigger is better, regarding Amps!
THANK YOU
high current doesn't matter but i think injecting more voltage to system (like 70 volt DC) makes trouble
Perfect video!!!!
i accidentally plug an almost 34V to my laptop. and my laptop shutdown and not booting up. is there still hope?
I like your videos !!!
Please make a tutorial video about ,mosfst,resistor,coil ,please show them to us on laptop mainborad
You need a secretary Sorin! HAHA
Is it possible to get my ROG laptop back to life again? Due to Sudden midnight flood my laptop damage while on sleep mode. I need your advice.
Thank you
Can relate completely with the can you fix it over the phone after 25+ years of auto repair.......Am not Harry pothead and the stoned sorcerer is AWOl and I do not have a magic wand.
true :)
So, it's okay to use a power bank with high amps, say 18 mAH to power up the laptop?
@dandon1105 That's normal response from racist.
You said you had 2500 subscribers. Now you got nearly 90 000 😁
LeFranck Not great, not terrible:)
Hi! Accidentally i created a short circuit on an USB port of my laptop. The laptop is HP PAVILION DV6 6C75LA, is there a chance to solve my problem? The laptop is not working, i can not see the bios, just the caps LED is blinking. Please point me in the right direction, i think its just a transistor but i dont have the schematics so... I really need help. Thank you :)
Your PCH is dead
You can't change the current only change te voltage and the resistance un can adjust the current. When you understand this everything will be clear.
sir, what's wrong with my laptop, it doesn't want to turn on even the vibration of the fan or even a sound at all, but the charging indicator is blinking in orange color, what could possibly be wrong here? hopefully you can notice me sir😢
I LOVE INTERNET.. THANK YOU GOD.. THANK YOU SORIN
I have lanovo ideapad 1.24 amps blow out from insigna charger 3.42 amps
The only one problem with a more powerfull charger in when the laptop have a short circuit inside, al tracks will be melted
Partial right, you have fuses and mosfets for protection
using higher amp charger will it make my battery life shorter?
No. The battery isn't connected directly to the charger. The motherboard has battery charging electronics and the battery itself has an electronics board inside to protect the cells. Biggest enemy of laptop battery life is heat. If you change the thermal paste of your laptop regularly (like once every year, before summer), every part of it, including the battery, will last you longer ;)
7:05 one of my pc burned pecause shorting +/- and never come back again
all that things have limit or all motherboards would have only 19v powerlines)) bring 19v in 3.3volts line and will see whats will happen
You stick a probe in the VGA and one in the USB port and the laptop starts charging? What the hell is it that I don’t know here?
He's connecting the ground ("negative") wire from his power supply to a random grounding point on his laptop (VGA metal shield, USB metal shield,...) and then the "positive" wire of his power supply to the central (positive) pin of his power jack. It's just easier to provide power from his bench supply this way. Otherwise he'll have to reach with both power supply leads inside the jack to touch the contacts - it's just physically more inconvenient and he risks easily shorting them.
@@em0_tion Thanks mate for explaining this clearly.
This happens with all laptops for example: Asus, Toshiba
When the Laptop needs 3A and charger is 3A it will work on 100% load. When the charger is 4A will work on 75% load. That is better for the everyone :)
start with like and listen hahahaha :)
Good. Too bad the customers never watch your video.
Hi,me i am very happy ans interesti'g about your vidéos.I live un Dakar west africa.And tour vidéos about vidéo help un m'y work un laptop maintenue.Juste i have some problèmes about Asus X200ca,the laptop Turin On baterry not charging.Nées help about this
Taste good does it
what about in 12 volts car battery can i charge my laptoo with the 12volts battery??
I X R = V Easy
so does that mean when they say a laptop or cell phone needs a certain charger to work, they are misleading the public ?? ...
I wish to be your only one subscriber to talk just with me lol
Please do car key remote repair no videos anywhere
ok, soon as i will get one
Electronics repair school thanks I love your videos and your sense of humor.
Like the videos, but the many ads are annoying😠
