Real troubleshooting from start to finish... I must say so far u seem to be the best presenter of this trade, touching every aspect of the problem at hand.. I love it... I pray that you have more subscribers..... I'll check all other videos on this channel... U r a good teacher.
Great tip about recharging 'dead' battery. I already knew that you can revive "dead" lithium battery by bringing it back to minimum level of charge, but drililng tiny hole on sides of the battery to recharge it instead of cracking the battery case open is a huge tip! thank you
I had already asked for a video of this a short time ago and here it is, thank you.
You're a great teacher. Thanks for sharing your wealth of experience. God bless you for being a blessing to many lives.
You are a genius. 👌
We Hope your back is well and Merry Christmas to you!!
Thanks for a great vídeo. The battery tip was perfect. It came in handy as I checked the battery of an Acer laptop. My Daughter went to your country for Six months as an Erasmus student. She liked it very much, do did I when I visited her. Kind regards from Portugal.
Hi Sorin, hope you get well soon. Take care!
Always surgically methodical and logical -- with just the right seasoning of humor.
Thank You for the tip to drill holes on battery's sides You are a genius hope you get better soon master
And again i learned something. Thank you master.
Good work, sense of humor that I like + Good manual work combined with electronics know-how. *Like*
I really appreciate you because of sharing all your experiences. Thanks a million
This guide about battery charging is priceless! Thank you Sorin! :)
Thank u master it is so useful things........
In less than an hour I have learnt how to check my battery and fix a broken charging port. Thank you so much ♥ ♥ ♥
i love your vid man
and the pop undertone in ur voice and execution. keep it up, pal.
Nice easy fix in the end with it being just the positive connection on the power input - good hack on injecting charge into the battery too to get the pack going. The Medion brand is the cheap tat they sell in Aldi - don't see why they would bother with a fan if it did nothing as it adds extra cost - if you look at the casing vents, it probably draws air over the processor from underneath and out the side without the use of a heatsink which would add further cost - not the best cooling solution but then it's meant to be cheap ;)
Your first funny laptop video ever, about the fan issue😸😸, the battery tutorial is very helpful and interesting, thank you sir.
I tried with an Asus battery (X55C if I remember well...) and damn, the internal battery cells were not disposed in plus-minus sequence as always (very weird). I opened carefully the enclosure and I applied the voltage on the right point. And battery live again. Thanks!
Thank you Boss for the tutorials
@Electronics Repair School: thank you for this video, I followed the steps and my daughter's laptop Accer now works again with a battery, it was "dead"
Dude is wearing a fully functional tri-corder on his wrist.
I LOVE THIS GUY!
hope you get better soon master
Thank you Brother for helping and explaining how to troubleshoot safely. I also appreciate you exposing the extra crap not needed.
Peace be with you
Great lesson sir..you are my teacher
An Absolutely Brilliant Demonstration of How to Diagnose and Repair Laptop Battery Issues
*1.* 5:30 This is a *GREAT* video, and a *GREAT* battery trick! I just did this trick on a 6-cell Toshiba battery pack which showed "plugged in, not charging." Your trick worked perfectly! It only took me about five minutes (plus time watching videos).
First I watched some other youtube videos, in which they disassembled battery packs similar to my Toshiba's 10.8v / 11.1v six-cell pack. They showed that the six batteries are just a series string of three ganged pairs. So I did what you suggested: I drilled a tiny hole in each end, pressed my DVM leads through the holes, and measured the voltage: a bit over 8v. I then clipped the DVM leads to a 12v car battery with double-clip leads, poked them through the holes, and watched the voltage climb from about 8v to a little over 10v. Then I put the battery back into the laptop, and over the next couple of hours it charged up completely!
*2.* The "magic bullet" that solved my *lower back pain* problem was to do *"crunches."* Just a minute or two of exercise each morning, in bed -- and if you start to feel discomfort then stop, it means that you are done for the day. In just a couple of weeks -- probably no more than 30 minutes total time expended -- you'll probably see major improvement. Searching UA-cam finds many "how to" videos; here's one:
ua-cam.com/video/MKmrqcoCZ-M/v-deo.html
Note: crunches are the cure for moderate lower back pain, not upper back, and not for serious problems like herniated disks. They strengthen your abs, which support the lower half of your S-shaped spine.
I wish you healing and thank you
Wishing you quick recovery master
great video mr sorin, ive got a few dead laptop batteries im going to try and bring back to life now ! :)
always informative, thank you ...
Merci professeur
Sir,could you please do a video or stream on how to use the power supply on the motherboard and when to increase or reduce the voltage or amps
Nice work.
Thank you.
Nice technical experience at its best, beautiful video... I have a battery that won't charge when fixed in my laptop, when I replaced the battery with another one it charges, the question is what makes my battery cut-off without any signs but, I can tell you I did allow some unectical practice though , for instance having my laptop on in my truck while I drive and I think couple of time I experienced shaking the laptop shot down, WHEN i BRAKE !!! couple of time before my battery went out...hope this is not the final burial for it... could that be shunting!?
Thank you, battery poor quality ?
Keep it cool...✌
Nice diagnose.
Soren hi there, for your back pain do massage and walking in straight road on up or down keep doing 👍 job
The battery has 2 negative pins on its connector usually side by side. one going to the negative of the cells. When The battery detects both pins connected to ground it will allow you to read the voltage of the cells and charge the battery via the main connector.
You mean the battery's conector or the laptop charging port? And once grounded both pins, it can be charged vía the laptops charging port or external power supply? Thanks in advance for the info!
your great sir i like 2 much how you fix things it great. thank to make videos to help people like me thanks for all your afraid
I like this trick! This will allow me to diagnose a battery when the laptop won't power on.
Hi, I have a quick question while changing the cells I noticed the new ones got really hot so a disconect them, whta could be the issue the other ones show good charge and only 2 were bad those are ones Im replacing but I dont know why they hot, are all the batteries the same ? In size they loock the same did I purchase the wrong batteries, please if you can give me advice, thank you in advance.
Great tip! Thank you somuch
YOU ARE A GOOD MAN
The hot glue technique was fantastic. I’m definitely adding that technique to my future projects. 👏🧠👍
Best ticer .Fantastik IT man
thnk you gain for all your videos
very nice videos. Sir do you have any video on how to use multimeter for beginners to troubleshoot laptop or desktop parts .?
Had an HP laptop that wouldn't output an image only while the battery was in the laptop. Battery pack only outputted 3 or so volts. A fine point X-Acto blade turned out great to drill the holes.
Have you try fixing Lenovo T420 battery before? I oppened mine, measure each cell is 3.6V, 3.6V and 2.4V. I thought the 2.4V cell spoiled but I can manually charge it. I measured capacity of each cell is about 2900mAh for all threel, spec was 5000mAh, that about 60% not so bad. However, somehow I can't get the voltage out of the connector. I checked the battery PCBA, fuse was OK, none of the capacitor short. The closed explaination I got from internet is the microprocessor flag it as defective cell when detecting inbalance. Any idea how to reset that without having couple hunderd dolars of equipment? or maybe some brute force way to fix it?
I have the same laptop 😊 white the same problem, now i can see whats going on.... Thanks man, you are crazy-inteligent 😁😁😁
What is the voltage at the pins where the battery is plugged in laptop. You know when you put the battery in the laptop, there are pins that gets connected to battery pins. What is the voltage I should expect when I remove the battery. I connected the laptop just to my charger and getting about 2.9 V at the pin that gets connected to battery when you put it.
great work u are doing,,, god bless you ,, i have a sony mbx268 board, it shut off within 10 to 30 mins (fan, heat sink all are ok ) it have amd graphics chip on board what should i do thanks in advance
Hi there, my name is Tiago and i am from Brazil , i want to say thank you for your good tips and really lessons. I am going to take some vacation in UK in a few months, i would like to know if it´s possible to meet you and give a chat about those things, i buy you the lunch ok ? I am learning so muchh with your videos , great job, very good person. I have a small shop about 20 years and i am learning eletronics about one year, need a lot of help lol .
AoA! You are a very Honest Person! May Allah grant you more than your expectations! Regards
200 IQ how to test battery thank you so much
20:30 dont laugh on my video... 😂😂😂 lmfao..
And get well soon.
God bless you master..
nice job sir..
Shot brother clever when you drilled a hole in each end I thought well why didn't I think of that
I have a Sony BPS-13 11.1v battery. I measured the outer most connections + - and get 11.3v. However
when it's in my Sony Laptop the charging percentage does not go above 73% and the Laptop amber charging light never
goes out. I tried removing the battery, holding the laptop power button down for 30 seconds, insert the battery but
still no change. I am not sure if the laptop or the battery is the problem.
I do not have the laptop charging configured to stop at 50% or 80% it's configured for 100% charge.
Could you offer a few things for me to try? Thanks, Ken
Have you ever tested a DELL laptop battery ?
I know when in windows the battery is charging, but when i take the battery out and try to charge it with lab supply, no current.
Ive tried shorting all pins to ground, but no result.
Do you know what action i must do in order to get a dell laptop battery to send out a voltage and accept charging ?
Hi, Mr. Sorin. I have a laptop HP Compaq Presario CQ61 that won't turn on without the battery inserted. The battery is dead but I have to put it in place and plug the charger. Otherwise the laptop won't turn on. Sometimes I have to remove and put the battery back for 3 or 4 times.
Thanks sir
you are the best
Fan is keep body laptop cool because air flow not really from bottom.. so its a little bit function.. yes not primary function for cooling the processor haha..
Verryyy helpful thank you
is there infinite ohms between the plus and minus of the battery connector? and if not, why not ? thanks
good show
OK nice video! My question is, how can I connect two laptop batteries in parallel (not interested if the batt case is damaged)?
Hi. TNX. is this method (get battery to life) will work - if i 100% sure, that my battery is ok, and all connections is ok??? My battery not charging after 2 y of not using on +/- new laptop, and its was 100% working before i stopped to use laptop. I also i tried all other methods - like reinstalling drivers, (even win7 to win 10 and back many times) unplugging battery methods , power switch holding by 20 seconds. p.s. battery visually looks like new too.
is it possible to charge a laptop battery with external power supply? i drilled holes in the side of the battery and . it is taking current and i checked it has 11v , but it won't work in laptop. laptop doesn`t charge the battery also. maybe the electronics in the battery are preventing things?
Can I use my spare charger adapter to give charge to my dead batter? The adapter is the same as my original laptop charger. I am thinking of splicing the cables of the spare charger and creating a jig to charge my spare battery manually while the other one charges on the laptop?
Hello sorin can i use my laptop original charger to charge directly into the battery pack like what you did there because im confused is 19.5v too much for a 11.1v battery to charge?
Use 12v from your car battery, instead.
How can I charge laptop battery like you did in this video ?? what did you use
OMG you are amazing Sir
Curious how many volts you used I have trouble seeing the meters in the corner...????
Sir, i want you to lecture us on laptop coming on for about 4 to 5 seconds and will sudenly off, what are the possible cause and the solution, thanks.
You da man, Sorin!
Please, I have read about the cp2112 adapter that it does the work of reprogramming or initializing a laptop battery and I bought one, but I do not know the correct way to plug and play, please I need an explanation
when i watch your video, there is a voltmeter/amp meter on top left corner of the screen, what is the model number of it?
i love it
Maybe it is a fan to cool the owner :))
how would you charge it if I have no tools to do it? my old laptop says %1 plugged in but not charging. Any help appreciated.
hello sir how can find compatible mosfet in other board?
what if i dont have that tool to charge battery?.. any solution or any way to charge the battery to any tool??
Hello, good day. I have an hp 840 G3 system that charges slowly. Also, the pc shows it charging even when I had take of the battery. Instead of giving a NO BATTERY signal, it gives 0% plug in.
What might be the cause of that?
Thanks for your videos, bytheway, they are very instructive.
Its ok if I charge the battery with a 12v 5A charger. Another option is 12v 2A. Which is better. Thank you.
Still very helpful in 2024. Thanks!
I add voltage to my batteries and it works once you get the voltage up.
thanks for the videos mine the laptop is boots fine without battery but when battery plugged in cannot turn on i put lab power supply and its taking 4.5amps on the ground. what could it be the problem?
probably you got a short li-ion cell there?, try with another battery
Question: what if the battery is charging but when you put it in the laptop the computer will still not turn on and it still says it is charging but never actually charges? I used your method to charge the battery, but it does not charge when in the computer. (ACER 5534-1096)
Thank you for your videos. Take calcium and magnesium every day. That will help your back greatly. Take magnesium citrate or chelated magesium....not magnesium oxide. 200-400 mg magnesium every day....about twice as much calcium.
Super Video.Danke!
my sony vaio e series was not charging and battery unknown remaining orange light was blinking rapidly not booting up by battery but booting up when plugged-in on ac power
Hi there,
I can feel your back pain up to here. If you are sure that you have no damage to your back and you are not yet being treated by a doctor, try the following: Go to a place where you cannot be disturbed, but can call for help if necessary. At this place there should be a stable vertical tube or a ladder or a railing that you can hold on to with your hands. You grasp it with both hands and then support yourself with one hand while reaching down a little further with the other hand. You bend your back further and further down without using the back muscles. The back muscles should be relaxed all the time. You just hang on your arm. It should feel good. Climb at that way up and down along the pipe but while you keep your feet on the ground and only go a little backwards or forwards. Do it very slowly. And make sure you don't have to make a sudden movement because the pipe falls over or you slip off. If it hurts while you are doing this, stop it and try again on another day. If there is no other damage in your back this can help you a lot by doing this only twice a week. Get Well and stay healthy ! Thanks for your videos and a lot of information. Greetings from Germany !
The fan extracts the warm air that builds up in the case.
he is pointing out the location of the fan.. which essentially renders it useless without a heatsink
I wish you very soon health recovery Thanks for another great video.When you make holes into battery pack to charge the batteries , you charged battery cell directly - so you excluded control charging circuit in the battery pack that laptop must use.Is it so?
What if the control charging circuit were faulty? How would you diagnose?
Thank you, i never found a charging problem, all the time if is a charging problem, it is the battery. You must have a mosfet connected to on serial mode with the battery, you can replace it
I meant that battery pack itself CAN be a problem. But battery pack = battery cells + electronic circuit( in that battery pack).
You measured/charged ( in the video ) battery cells ONLY. Is it so?
But what if that electronic circuit (in the battery pack )is faulty? Will the laptop charge?I do not think so.Or am I wrong?And how do you test that battery cells are OK but electronic circuit( in that battery pack) is faulty?
its not even important as you can't fix the battery electronic board. Any repair attempt on the battery board will result an permanently not working battery. The memory of the battery board is extremely sensible
@@electronicsrepairschool pls sir, on the video,you made mention of supplyiing power to the battery or better still charging the battery directly to the cells, pls what do you use to charge or supply power to the battery, is it the multimeter? thanks.
Thanks I really appreciate holding the b and holding the windows key helped me 😊
Hello
I've tried this on a battery. I made holes on either side and measured the voltage was 7.5v.
When I put power there it takes no current from my bench psu. Can you please explain to me why? Thank you you are my favourite channel :) God bless
Dead battery
Checked the voltage getting just over 4v on the battery connected 12v (drill battery) each end as in video started to get warm voltage dropped. Guess its a short.and can't be fixed Am i correct?. Thanks
What is used and how do you bring the battery back minimum voltage. I'm new here and don't know what everything he is using.
Blob of hot glue and a bit of solder :-)
