It’s true that you have the right equipment for fixing the battery, but the way you put everything together and know exactly where to look, it sounds like it’s a child’s play 😂. Well done!
hello we are back saturday and we have a nice laptop to repair
Look this, is a nice motherboard.
@@demostenesramos check here
@@demostenesramoshave you spotted ram?
Check here
Finaly friiiidaayyyy
Apart from the astonishing knowledge about laptop batteries this great man possesses, we can only hope the properly calibrated solder actually blows when needed
Good morning Sorin. I've been watching your videos for a month now I watch what you add on a regular basis and I have also been watching your videos for 6 years. And I would like to thank you very much for the invaluable knowledge you share with us beginners. I feel that you are a very good person with the love with which you do this and I thank you for everything. I wish you good health and best regards.🤝
good call -- all from experience .. TY ...
Thank you for the knowledge
What a pleasant channel, throughly enjoy!
Hello good sir is a pleasure to SEE a Nice repair
Thank you for the knowledge.😊
Well done Sorin
Renesas/NEC is very well known old brand and big one like Infineon, Microchip Motorola. They all play in same circles pretty much in different industries.
Hello sorin, you are really a very ❤🙏🙏👍👍👍Good person, thank you very much for the training you give us with all the details
Now I know how I can help my brother. Thanks for a very good video.
Thank you sir I appreciate your knowledge sharing with ❤️
That was insane.. holy crap
My only question with this fix is that you have replaced the fuse with a blob of solder, so it won't be the same rating as the fuse that was previously on the battery.
Isn't it likely that IF (and a big if) that cell was faulty and the solder stays connected and not blow, could this cause a thermal runaway effect with the cell/cells and cause a fire?
The battery board should still have MOSFETs that can be turned off by the battery controller, but yes, removing a safety is *never* a good idea in a lithium battery, and here we even already have hints that a cell may be going bad.
Btw the fuse is specially designed so that an external trigger can blow it (from the battery controller in case of a permanent failure event, which is a safety mechanism), if you fill it with solder that won't work as intended either.
This battery should definitely not go back in the machine like this. Better have it disposed of and get a replacement one.
What could possibly go wrong with Li-ion batteries. its not like they can overheat while the laptop is charging in the middle of the night and cause a fire and burn down a building and everyone in it. That would never happen. Geez /s
Hard to tell in this video; but, if there's anything left of the fuse medium then a solder blob just reconnected what was left and there's still enough material to blow again if needed. Otherwise, this is no longer a fuse, it's a bridge and a short waiting to happen.
Just get 4 LiPos in series and short it with low-melt solder and see what happens. I'm guessing the high discharge rate of LiPo will melt it, ie, assuming 3000mh x 4 cells, C1 rate is12A, C4 is 48A.
It's calibrated solder, You should know this by now watching his video's
Love from Somalia 🇸🇴 big fan 🎉
master respect!!!
well done
Hi Sorin! -I'm having a problem with my own Dell laptop, which is very similar with this one... I didn't check the battery output yet... thanks for that!
damn would like to have that battery tool its so sick good ! holy moly!
No proper calibrated fuse?
proper calibrated solder
17:30 that triangle on top of the battery icon in windows doesnt look too good xD
Amazing fix. What I never understood was, if the chip has all the information about the cells, why can't it deal with unbalanced cells? I mean, not the program, but the battery controller itself. It should be more intelligent than "I can only recharge balanced cells" by now...
laptop batteries controllers dont have external cells balancer on the pcb, just integrated microbalance circuit inside the AFE of the chip. Its throughout (5mA typ) is so low that it cant equalize such a big voltage difference like shown in the video. It could only handle deviation up to 30mV and only during charging. So unbalances over 50mV should be fixed manually.
@@electricelectronich9979 Thank you for the explanation!! It was a mystery to me.
Still, I think they could devise a better solution than this. I may be wrong, but it doesn't strike me as a difficult thing to solve.
Nice lap top😁💪💪👍👍❤️
Se vedea pe ecran în softul de testare la baterie ca bateria asta este din 2020 fabricată deci fie este cea originală sau schimbată cu una veche nefunctionala. Legat de siguranța care au lipit-o nu trebuia să pui o sârmă calibrata ca să nu ia foc în caz de vreo problemă?...
From the Philippines ✌️✌️✌️
Why is the board taking 14v but battery 17v? Why they have used a boost circuit? Is it normal?
Hi am from India
Hello Sir, How to unlock battery wothout the machine u have
Sorine please help me I have hp laptop G1 it's hanging on hp logo and no blacklight.
With the right equipment and some knowledge gained from years of repair some things begin to look easy.. When you start out nothing is easy🤣 I'm sure there's a lesson in there somewhere😍😍
Is that battery analyzer worth getting?
No. Just replace the battery If you need to. It also require a subscription.
@@modorangeorge4991 Subscription is only for Repairing and its price is equivalent to 2-3 genuine batteries. So, if you repair 5 batteries in a year, it worth it for sure :)
I still can't understand why they change the battery and it's still not charged?
Is that nlb analyzer a normal price yet without a friggin subscription? If not, i'll ask again next year..
NLBA1 has the best price in the world. Nothing can be compared to its features and its price, try to find other hardware to do the same analysis and you will see :)
@@azzidoqsc I would even pay 1000 euros if not for the subscription model.
@@fliporflop7119 with 999$ you can buy 10 years of Unlimited Battery repairs.
It looks that cell was discharging after you charged it
do a full discharge and a full charge and you will see that the health state(which i guess is % of the original capacity) of the battery has decreased
Hello, there is a problem with my laptop hp 8560w - when I disconnect the power from the charger after 10 seconds, the laptop turns off, and when I restart it it works fine and the battery is fully charged without any problems - but if I disconnect the power from the charger and unplug the charging plug, it does not turn off at all and continues to work, meaning that the problem is Only when the power is disconnected from the charger. I replaced the charger and nothing changed. I replaced the battery and nothing happened! They can help me. Note that I have information on electronic circuits
Is the battery analyzer your creation?
I've seen it here and a few other channels. It's the NLBA1 Professional Laptop Battery Analyzer
@@TheHalo14aus thx
Hello Sorin, would it be possible to unlock this battery without the use of your tool?
I do not want to invest hundrets of euros just to unlock a few batteries.
Do you know whether there are other maybe a bit more complicated but free methods?
Thanks and best regards,
Andrej
No, it is not possible to unlock laptop batteries without a dedicated tool. All the cheaps are well secured. The analyzer is a must-have device in any repair shop, it is like a multimiter.
There was a small cut on the lithium cell. Isnt that a problem? (11:05)
Just a scratch
literally trouble on my xiaomi laptop, gonna check how its work)
Is there an alternative for unlocking the battery without this software.
Other softwares, 1100$ license for 1 year.
Companies keep using these obscure chips to prevent repair and I think that battery replacement was probably 2nd hand when they put it in. 51 cycles isn't brand new!!
that must be a fake battry with unknown firmware causing the problem
here replacing the battry can fix the problem
Hi ihave a laptop acer v5 no power and the EPROM is so hot when I connect the charger
give it to a repair shop, it is not going to be fixed via comments
without analyzer how to reset
you can't
Hmmm, yesterday my dell inspiron 15 suddenly battery dead, I asked shops for new one,than your video appears, i searched how to unlock and now all ok 😂
I missed your video the other day, and man, my day was so boring...
Hi I'm from Earth.
Dragobetele 😊
Sorin you always repair any kind of laptop problems but in battery repair, you must have a fire extinguisher near with you. ⚠because bad things can be happen at anytime.
Ya, he has a fire truck in the garden, and I knew because I have seen it...
Love your channel. Good sleuthing here, but "repairing" that blown fuse with a solder blob is a dodgy solution. You are leaving yourself wide open for a lawsuit if & when that laptop burns down a house.
👌👌👍👍
Day off for DELL 😆
Hello🤝👍👍👍👏👏👏👋👋👋
most likely that battery will die again soon... most likely the battery died because of different internal resistance of the cells
for sure he does not know this, he just learn electronics by watching couple of videos on youtube
@@user-ug9nn 🤣🤣🤣
It depends. In some battery designs, I have seen that the chip is powered by just one cell. The chip consumes power so if it is powered up from just one cell then after long-term storing one cell will get lower than the others. The same issue I found in the Makita batteries.
company sabotages the laptop,.. even if it is new battery,.. reduces capacity,... through hardware scans,... ruins hard drive by introducing bad sectors through update patches,...
The battery cell probably has a different SoC, this battery is not fixed. The fuse blew because there was more current because the voltage dropped and the DC/DC converter line of the laptop increased the current draw or, it has something to do with that bad capacity of one cell with low voltage. The laptop is now probably dangerous because the battery can overheat and catch fire. I would definitely replace the battery with a new one.
Thank you very much for the opportunity to watch very informative videos. But this is the first time I feel the need to discuss to avoid an accident. But maybe nothing is happening and I'm worrying unnecessarily.
this fuse is not curent driven blowotu, but trigered by microcontroler
@@user-ug9nn exactly, good answer. In this case it was triggered because of big imbalance.
🪄🧙 👏
How come the chinese didn't copy this device already?
And selling it cheap.
It is already cheaper than the Chinese tester Poloso RFNT3. RFNT3 is more expensive, 15 years old, has no updates and has max 5% of NLBA1 features. Of course, it cannot unlock batteries.
Anybody trying other affordable options /devices for unlocking batteries. Mostly just easier to buy another used laptop. Facebook marketplace is full of cheap laptops starting for free and soon people will give you money to take theirs away. Haha. How times have changed. Free Julian Assange from English Tyranny.
Those used laptops have most probably the same locked batteries, so, you need to buy another used laptops :))
