Hi Sorin, the reason for the shutdown (at minute 11:59 and at minute 12:25) was that there wasn’t enough current from the power supply. When you charged the battery, the limit was set to 1.83 amps (at minute 13:00). After increasing the current to 3.03 amps, the laptop was able to start. It had nothing to do with the battery charge or with the bios. Thanks for everything, and I appreciate what I learn from your videos every day.
yeah i caught that it didnt have enough amps to start the board til he increased the amps to 3
either way he is good and fixed it nonetheless. he knows what he is doing
Yes, Sorin is amazing. I’ve learned and continue to learn so much from his videos. My comment was just an observation, and I believe it’s correct as well. Thanks also to his teachings that I’m now able to make these kinds of observations. I know very well that he knows what he’s doing :)
@@Ripara-Zione yeah i agree thanks to this man i have fixed several of my own pcs and laptops.
I have repaired a good few laptops now and yet I almost always remember something when watching these videos. Thank you for continuing to upload them!
I found my joy. I can't wait to get home and see if you've posted anything! When you do, it brings back the joy I felt as a kid when watching Turtles Ninja or Captain Planet. 😊
I always get happy when I see a new Sorin video. It's been years now and I still get excited.
Somehow this reminded me of a TV engineer coming out to repair our family TV set in the 1970's. I was a young teenager and mad about electronics and got talking to the friendly engineer about the fault. It was a missing power rail and we both discussed possible causes and we agreed it was either an open diode or dropper resistor. The resistor was difficult to reach/measure and the diode was easy so we replaced that... "We have picture" (or words to that effect)!
It was really good fun and I learned a lot that day.
Why am I telling this story? I wonder whether viewers might be prepared to bring their laptops to Sorin and pay for him to personally coach them through the repair process.
i love how Sorin explains every details on what is happening. very clear and simple. very effective tutorial. 👍👍👍
Always enjoy watching those videos, even the short ones. And have to be honest, completed an apprenticeship as an Electrician 20 years ago, only got the chance to do the minimum soldering/testing required and I can confidently say, even these short 15 minute clips teach more than we learned in like half a year.😉
I've been doing some board repairs on top of my usual PC repair stuff for two years now and I think I've only seen a shorted second mosfet once during that time. I mostly get shorted caps.
Hi sorrin, thanks for your time, you must do an episode of the proper impedance that some components have, for example PCH or memory according to ground plane
Hi Mr. Sorin and thank you for sharing your great videos. ❤
Thank you boss for all this great information!!! ❤
Thanks for the lesson
Sorin, dude, you are just plain good!
Thanks master sorin... For lessons. ❤❤❤❤❤❤
I like to see your video and learn from this. Do more video like this. Thank to your video I can repair some five laptop for myself. Thanks.
Thank you for all your videos, I want to send you some pictures of my dead motherboard
Hi Sorin, what pleasure to see a new video, thank to share how to check e fix this common fault... Always quite abd precise lesson...never i'll be grateful enough to you that give me the opportinuty to update caminng from old THT... Only a question....Can you give me live consult and support during same for my experience hard repairs via Skype or else, paying your time... helping one of your supporter and subscriber...we have only one hour lag..bye Francesco Timpano from Florence Italy 😊
more videos Sorin please, thank you
Sorin thank you, even though i am not an electronic guy , but i learned soooo much from your videos, keep shining !!!
geat knowledge bro
Hello, I watch the videos you make and they are very informative, thank you.
You have the possibility of making videos on breakdowns other than mofsets and short circuit capacitors. Thank you in advance.
Good job sir
Need to bring out merch saying Mosfet and WE HAVE PICTUREEEE
the perfect diagnostic
Nice fix but no proper calibrated fuse this time and IMO the most common fault is BSOD (blue and black)
Excellent
Hello i spent over 5 years following your channel and everyday improving my repairs skills but i never see your repairs tools setup. Pls can you show little bit.
Me when Sorin says easy pizza 😃 Me when Sorin says no easy pizza 😭
Very Nice! 😎
Nice one
12:38 because you don't have enough current(amps) on the power supply(1.84 amps set)! You forgot, always 🤪
Normally he hears the current limit relay kick in for his psu to remind him but maybe his age is starting to effect his hearing 😅
Its ok master sorin knows that's hes legend. 🎉🎉🎉🎉
Beautyfull repair from the one and only expert on RUclips in my opinion. I was however afraid that, that cap exploded because of the amount of heat but gladly it didn't.
great❤
Quanto vocês cobram no reparo de notebook?
Sorin, I'm a little lost. If the first mosfet is cuting the 19v by the control of the BQ how came we had 19V at the double diode?
The bq chip is taking 19v exactly from the charging port!!!!
Ok thanks. It makes sense if it needs to control the mosfets. Thanks for replying.
Proper PIZZA, except taking the board out 😅
merhaba sorin 15;48 neden 0.03 v ? ve laptop çalışması için neden bataryaya gerek var? adaptör takılıyken batarya dolu veya boş çalışması gerekmiyormu.
Don‘t get exactly right, removed mosfet is SM 3319 and is N channel, but replacement is 7410. what about even or odd numbers denoting N or P channel?
AON 7410 is N-channel MOSFET
hi brother, i have a question from one tech to another. im trying to fix my sisters laptop and here is what happen. (ill post a video too) computer fan cant blow out air because it was blocked with dirt and dust, so computer got too hot and the fan ceased up so it had a thermal shut down my sister not knowing anything just turn it back on like nothing is wrong. so now the battery is swollen and the charger IC chip blow up and the board where the chip was has burnt layers and the laptop wont turn on with 19V present. is it possible to bypass the charger IC area to make the laptop power on? i know she cant use the battery just on AC power. if I can get it to work then i need to source out fan. thank you in advance in assisting me in the escalation of this issue. i would send to you but im in canada seems maybe too far
good day sir how to fix lenovo edea 320 corrupted bios thanks
How we know it is n ch mosfet by knowing that gates is together
I just started working on top loading washers lol easy as pizza
Hi Sorin how to detect power management chip is not working
An ic/chip contains many transistors which makes a chip/ic nearly imposible to be tested with a multimeter, the only way to be sure is good, is by replacing it.
@@electronicsrepairschool okay noted but on the video you tested 19v on the transistor, etc ic around that chip meaning if 19v is present around that Pu chip, it looks good?
Hello, how do I study notebook and cell phone using high definition photos, that is, without having the motherboard physically, any tips? Thanks ❤
Olá, como faço para estudar placas de notebooks e celulares usando fotos de alta definição ou seja sem ter a placa fisicamente, alguma dica?
lenovo laptops die like flies, their hinges break everyday...their biggest issue is the customers who thought lenovo is decent brand and buy it,but it ain't,its a ugly scrap
No propper calibrated bridge anymore, nice😂
Greetings. I am always amazed as to how Sorin can manufacture those perfectly well calibrated fuses.
Apple should take Lenovo to court and sue for using the "I" prefix in it's naming of products.😅
Proper classic easy pizza
Do you have budgies? I can hear chirping.
I hate laptops with a soldered RAM
lick squid damage
we have what
I will NOT support this channel until Sorin starts making money for steak 🥩 instead of pizza 🍕!
Pizza kills you, steak heals you!
Today u have a easy pizza
Easy pizza buy 2 this time
easy pizza hann 😅
☕☕☕☕☕
Another pizza, but not such an easy one this time.
If you don't have any scrap boards to remove a mosfet from they are available online
but be caerfull who you buy it from, there are a lot of fakes these days.
i love how Sorin explains every details on what is happening. very clear and simple. very effective tutorial. 👍👍👍
