I love your calming voice and the way you teach there is also one more Chanel named northridge fix you both are the ones I like to see the videos of yours are much in depth and his is fast and i often watch it as an asmr video as he has fixed the terrible soldering work of others who have tried to fix the device reflowing all that solder and the cleanliness of the work is one of the most like to watch .❤
Another informative clip nice and steady with checking out fault ........you do make it look easy, but experience is the main factor. Thank you for sharing with us
Just got one of these cheap from eBay for £283 took a chance since I needed a half decent laptop. Turned out all the faults were easy fixes. Well chuffed.
Very nice laptop, I'm writing these words from a same laptop (mine is a 17" one tho). This laptop will suffering overheating issues after disassembly. You need a special thermal paste for that.
@@kimoleto5178the heatsink is pretty much made with that PTM phase changing thermal solution in mind , i have heard that using sometjing else even if it will provide good temps it will last a few months at best
Good job sorin and you are lucky, sometimes can be a short on the screen, i usually use a power supply first to check At the end "i can't beleive it's working we have picture hahaha'
I have a laptop that is the same model or close enough. My backlight stopped working right after I swapped out a broken LCD. I was worried I shorted it out since I didn't disconnect the battery first. (I know I know) I suspected that I popped the same fuse, but I'm testing it and the continuity is fine. Perhaps it's just the 40pin LCD cable for me?
Sorin, why not check for short on powerrail ? You did that off camera ? That's why I liked the unedited vids more ! Ahhh the good old days... (Give me one second!)
Love your videos! I have a Lenovo legion 5 that I replaced the screen with after it was damaged. I didn't take the battery off and now it looks like the board has blown a fuse. The laptop will look like it's powering on (power button lights up) but the screen doesn't come on, even on hdmi it shows no signal. Is this something you can fix?
my Lenovo Legion 5i need to change battery 60wh Model L19M4PC0 And i need to change Model 80Wh Model L19M4PC1 When i Replace No charging the laptop and i wait 24h still Not working do u tell me How
Amazing for a couple of reasons: -He knew it was a fuse problem -He knew where the fuse is located RESULTS: a job of one hour or more for others was done in few minutes for him
I don't think he necessarily knew where the fuse was located or whether it was the issue. He found it quickly by logical thinking, which is the way to go and what he actually teaches.
Can you please help me?? My lenovo legion 5i had its motherboard replaced. I am unable to start the secure boot from the bios menu. Is there anything that can be done ??????
First go into the BIOS, disable legacy boot, then enable secure boot . Rarely I have come across some models of laptops (acer) which allows secure boot only when we set administrator password for BIOS!
@@arsucka Make sure that your hard drive is initialized as GPT, secure boot work only GPT partition table! If yes, try disabling TPM on the BIOS save, exit, then enter again ino the BIOS & see whether that option grey out is gone.
@@Aneesh.Asokan Wheneven I am trying to interfere with something in the bios, the tpm get disabled by default and i am unable to get it back on. Then I have to flash the windows again to get back the TPM
@@arsucka As default, legion laptops comes with UEFI & secure boot enabled, then how it went into CSM MBR mode? Go into your BIOS boot options or advanced boot options, enable UEFI, some BIOS do have an option legacy & UEFI then enable secure boot, save & exit BIOS. If still that option is greyed out, set administrator password to your BIOS save, exit BIOS. Then re-enter the BIOS typing the administrator password, then you may be able to select secure boot. I have seen such scenarios on some servers. Good Luck!
Please help me I gat a Lenovo legion 5 it comes on but no caplock nor number lock light comes on and no display on screen but the fans and the processor are active
Forgive my ignorance, but is the replacement fuse just a piece of wire? I just opened up a Legion 5, found the fuse (at least I hope it's the one) but now am a bit stumped.
i have the same issue on my acer nitro 5, can anyone give me an cost estimate on the repair. i cant do this myself because i lack a goold solder and voltmeter.
You have taught that fuses usually blow for a reason. In this video, I don't recall seeing you checking for a short. We're you going by experience or is there a condition where you should try replacing the fuse first? Watched many of your videos, thank you for the content.
That's what he was doing when he worked the lid back and forth, and that's also why he tested it with the charger plugged in. He is probably not going to charge for this repair, so it is not worth it to spend hours exhaustively searching for a short. Just give it to the customer and they will bring it back if it happens again. Be smart with your time.
That is not necessarily true. A short may be hidden behind an active component (transistor), or as Sorin said, it may be something like a capacitor that only shorts at a higher voltage. If finding shorts was always as easy as putting one meter lead on ground and the other probe on a fuse then fixing electronics would be a whole lot simpler and no one would watch this channel.
My first laptop was a HP that developed this same issue. HP wouldn't fix it without changing the motherboard which made it a not affordable repair even though in retrospect it was an easy and cheap fix, replacing the fuse. After that I stopped recommending HP laptops to anyone. I just wish their was a laptop that worked. The most I expect I need to do to any laptop now and then is replace the thermal paste. Can anyone recommend good brands that never break down or break down less often. Bad experience with HP, MSI.
If u want ultrarepairability and upgradeablility then framework, its costly yes but you can just replace parts over time, which could otherwise make having new laptops cheaper. And as for rule of thumb maybe avoid macbooks and of such.

Make a video when you deliberately mis-plug the screen connector and see if the wire fuse blows or not. On a scrap board that you don't care about. Let's experiment. :)
Sorin, you should once calibrate your "Proper Calibrated Fuse". (Do several experiments to show when they burn. BTW: A very interesting video with the principle of fuses: ruclips.net/video/apQU_VuJlFU/видео.html )
I really don't like replacing a fuse without a root cause. These drive me nuts. Hopefully, there's some rational explanation involving the customer doing something dumb while attempting to clean, or adding memory, or whatever. If it's embarassing, then we may never know.

I'm always AMAZED when Sorin did fix the problem by saying "I Can't Believe"
he can't believe it just as simple as changing a "fuse" 😅

I was for the "proper calibrated wire" mention 😂 love this guy. 7:22
"proper calibrated fuse" 😎
Amazing Job!
Interesting thermal paste application 😂 great job as usual.
Good job 👏 👍
Nice video! 🙌
The Pc doctor does it again 😁
Good job as Always. ❤❤❤
always amazing🔥🔥

What is the special thermal paste for this laptop?
@@derekhatake Exactly.
The kind that transfers heat

Thanks!🙋🤗👍
Beautiful repair 😁
Thank you.
thank you sir...
Looks like pc3109 is showing burn or is it the lighting?
I saw that too like a hole in it, but could indeed be the lightning 😅
Thank you Sorin.
What may happen if, let's say the proper fire is too strong and won't blow up? Probably the fuse on the screen's board
5:09 - PC3109 doesnt this component look burned? Diode or whatever it is. 2 burn marks visible.
Looks like maybe a drop of old flux and a scuff mark to me
شكرا بجميع اللغات
What is the wire(fuse) diameter which you use for these cases?
probably 0.1mm
Amazing
Fuses are there so that Master Sorin can jumo wires to FIX......😂😂😂
Sorin, just out of interest would you test one of your " fuses " to see how many amps they can actually withstand ? Regards
Hi my friend what did you solder the fuse to. I couldn’t tell where
To the ground track
Thank you sorin for sharing ❤going straight to fault...just a thought though..why didnt computer shop replace fuse🤔
They don't have fuses 😉
@@aviandragon1390 they must replace with proper calibrayed fuse🤣🤣😉
Only he can manufacture those. They don't have the skill.

"Dodgy manufacturer.. hehehe" 😂
Sorin¡¡¡ You should do a video blowing up one of your "perfect calibrated fuses" and show how many Amps are necesary to burn the cable¡¡¡ ;-)
This is THE lesson on how to proper calibrate fuses if u hadn't noticed, one extends the length of the wire 🤣👍👍
I have several spools of that properly calibrated wire. 😅
Proper calibrated fuse
What is the address i can send my laptop to? Please tell.

A fuse is a wire in plastic capsule

Try to repair psu like this just replace the fuse
sorin read a montherboard like it is a book. it would be cool if he can engineer a motherboard, or recommend a proper motherboard
I’m new at this but it looks to me LG1 could be bad. Just a guess.
"a proper calibrated wire" is about 4A fuse.
