beginners said "battery is dead, lets buy a new one" but experts always have a solution.
The experts got skills and tools cowboy...
Amazon has run out of power meters because of Sorin, everyone wants to be a Sorin to someone's life 😅🤣 Love from Montreal, very insightful repairs as always 👍
"Clearly, this port is soldered properly." You've got faith and great skills, Sorin! I would've been praying I'd soldered that charging port correctly - especially with horizontal and vertical pins that all need to make contact! Awesome work.
I would swerve that DC jack repair based on what I *now* know 🙂
Thank you Sorin.
Every day we learn new things from your valuable videos.
In the NLBA software, go to "Check Cells" and then "Wake Battery", this will force the battery SoC to communicate again and it will then take charging current
wow a dead battery brought back to life , hats off
i like how you solder the connector , very confident and professional
Merry Christmas Sorin and family for this week have a great day 👍Ps keep the great videos coming 👍
"This is a nice Lenovo Thinkpad" - not the same Lenovo company who's products he's slagged off, saying he'd never buy one ? Still great videos, thanks Sorin
hello mister sorin. thank you for creating all this wonderful video. I write this because I have a 60V 5A power supply which had the same protection as yours on one of your videos. and I also have the cables that heat up with the Current at maximum like you. the Manufacturer gave me a manual to follow to adjust the current meter omoin to 5V and touch the cables and adjust the current. BUT it all describes errors because the protection is the power supply fuse only and the power supply only. and is not specified that it does not detect any short circuit on the mother board. he speaks only of the protection of the power supply. the fuse for the overvoltage and the short circuit is to touch the cables together without breaking the machine. otherwise it never detects anything on a motherboard ( i have use translator i from Quebec ) my model power supply is ( Jesverty SPS-6005 )
insane man. thanks for sharing. learned so many things.
Another happy customer! Great Sorin, thank you!
Good job Dear Sorin
Excellent tool, indeed Sorin.
NICE JOB Sorin!!!!!! 👍 Good video!!!! 🙂
Very informative and thank you
Thank you. You have no idea how inspiring you are. I found a new love,...electronics. My low water light stopped working on my coffee maker and I had to find out why it's not working. Water probes would never go 0L on ohmmeter and impossible to rig it. I added a 1M ohm resister and it works now! I fixed my laptop twice and learned how to use hot glue, fabricated ribbon connectors(cause I ripped one assembling) with super glue and a very fine file. I wished I learned this 35 years ago, because I just found my passion
Nice job.
Another advice would be to left a battery Charging for an hour in the Nlba1. Some chips start precharging by injecting small charge with timeouts, untill voltage build up over 3...3.3v then it start charging normally. It was observed one such injection at the beginning of the charge.
You're a genius!
Hi
I watch your videos and they are very useful
great analyser :)
Now like seriously, how can i become this good like you ... !!!? can anyone please let me know any of the tips !???
Reminds me when highly dehydrated person is supposed to sip water very slowly in the beginning.
it may go back to the same state if you run the battery to zero again...customer may not be able to start the charge again if it the SOC reads bad again....i would run it to zero and see if charges again, ...great video!
You my friend is the best
I think it was the reset in the NBLA software that fixed it. I've seen BQ chips that were unresponsive were crashed, but simply grounding the /RST pin temporarily fixed it. (I know you said it wasn't a BQ chip in this video).
lithium battery's that go to zero lose bias and need a little bump so the system can sense what end is positive. the battery may be good afterwards but it'll never be the same.
That's true but has nothing to do with the video. The battery was at ~3v / cell.
SANGAT LUAR BIASA SOBAT👍🏻👍🏻👍🏻
Sorin. Would it be possible to do this without an analyzer ?
GOOD Video and well done . I'd like to know if there's any other tricks or methods' to reset or refresh a battery without using this peace of hardware tool (battery analyzer) to ignoring the SOC state of charging ?
You can do it with a linear power supply. V set to 12 and A set to 2
@@leerzeichen1910 thanks
@@anshadedavana i know what you mean, but if that's the case you just have to put the probes after the SBS, if it's possible; if not than yeah, you have to buy that device. right?
in my experience to fit one of these type is the better option vs the type with horizontal pins on the underside of the port, you cannot see or know anything is correct. it sucks. this port is quite frankly a doddle by comparison, alignment is instant. if its in, its in.
very funny. Battery is telling IO chip "I am dead' and later "it wasn't charging before". hilarious :))))
Cool nice ♥️🙏
Did it not charge because of the undervolt state? 3v per cell
HI SORIN, I WOULD BE GLAD IF YOU COULD HONOR MY SPECIAL REQUEST.
KINDLY DO A VIDEO ON HOW TO FIX COMMON PROBLEMS OF POWER ADAPTERS AND HOW TO IDENTIFY COMPONENTS OF THE POWER ADAPTER.
ADAPTERS LIKE FLAT SCREEN TV POWER ADAPTERS, DIGITAL TV RECEIVER POWER ADAPTERS(9V, 12V) AND LAPTOP POWER ADAPTERS.
THANK YOU SIR.
Hi Sorin, that's why I personally HATE machines like the NLBA you mention: are a valid help if you continually update them (by paying a fee, of course).
Once not updated, quickly they became almost useles, since there are *A LOT* of new chips coming out almost in a everiday basis. that make the very same function inside the battery, but are different for any reason.
But these reasons there's not to aim to a better product (i.e. PC), only to complicate the things to more people, who believe that can use that info to work with; but this will be true only for a short period.
SAD
Can't you add your own tiny BMS board. Sure windows won't record it's level but that's another option right?
I hate till date those laptops for those ports. I've got as well one Lenovo here and each port cost about £10. When I see those vertical and horizontal pins, I start to pray :D (I'm not a religious person). These are the worst when at the first attempt you can't insert it and £9 is going to the bin.
This is a very useful piece of equipment to have for laptops repair this saves a lot of time nice fix
What is NLBA Analyzer??
Just by the way, I don't use such tool as you're using. When it happen, all I'm doing is charging the battery with my bench power supply and it reset itself if that was a firmware freeze. I don't know in which case this NLBA would help me. Any advice?
if you could reset the chip just by precharging the cells, you no need any special devices for sure)..
could u have charged the Cells directly ? to have some voltage so the chip thinks its fine?
Possible
Why engineers pushing type c port to use for charging with high voltage and current nearby data lines? There has to be a charging port only use for charging.they re designing it for broke the laptop after a few time insane
When the laptop is charging the battery correctly, what should the amps be??? I know you mentioned and you could see it on the device that it was .03 amps. What is considered normal? What range? What is abnormal?
Please watch the video one more time, without skipping :)
@@electronicsrepairschool 2amps it appears
What kind or brand of battery analyzer are you using? Thank you 🤓
Its made by NIP-Embedded
@@electricelectronich9979 ok, thank you 🤓
The battery has Firmware that will be updated from windows with windows update 😂😂 I know is ridiculous
as alex would of advice from northbridge is to heat the board from the bottom for ports.
Merry Christmas Sorin and family for this week have a great day 👍Ps keep the great videos coming 👍
