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.
Thank You for the tip to drill holes on battery's sides You are a genius hope you get better soon master
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!
I really appreciate you because of sharing all your experiences. Thanks a million
Always surgically methodical and logical -- with just the right seasoning of humor.
You are a genius. 👌
We Hope your back is well and Merry Christmas to you!!
This guide about battery charging is priceless! Thank you Sorin! :)
Good work, sense of humor that I like + Good manual work combined with electronics know-how. *Like*
And again i learned something. Thank you master.
In less than an hour I have learnt how to check my battery and fix a broken charging port. Thank you so much ♥ ♥ ♥
Thank u master it is so useful things........
Thank you Boss for the tutorials
hope you get better soon master
i love your vid man
and the pop undertone in ur voice and execution. keep it up, pal.
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

An Absolutely Brilliant Demonstration of How to Diagnose and Repair Laptop Battery Issues
I wish you healing and thank you
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 ;)
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
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.
*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 RUclips finds many "how to" videos; here's one:
ruclips.net/video/MKmrqcoCZ-M/видео.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 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!
Your first funny laptop video ever, about the fan issue😸😸, the battery tutorial is very helpful and interesting, thank you sir.
Great lesson sir..you are my teacher
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.
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 ! :)
Nice work.
Thank you.
always informative, 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 ?
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
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 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
Merci professeur
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 ?
Great tip! Thank you somuch
@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"
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.
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.
Keep it cool...✌
Nice diagnose.
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?
is there infinite ohms between the plus and minus of the battery connector? and if not, why not ? thanks
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.
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!
I like this trick! This will allow me to diagnose a battery when the laptop won't power on.
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?
Soren hi there, for your back pain do massage and walking in straight road on up or down keep doing 👍 job
thnk you gain for all your videos
20:30 dont laugh on my video... 😂😂😂 lmfao..
And get well soon.
God bless you master..
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
OK nice video! My question is, how can I connect two laptop batteries in parallel (not interested if the batt case is damaged)?
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.
Verryyy helpful thank you
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.
Curious how many volts you used I have trouble seeing the meters in the corner...????
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
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.
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?
YOU ARE A GOOD MAN
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.
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.
nice job sir..
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
very nice videos. Sir do you have any video on how to use multimeter for beginners to troubleshoot laptop or desktop parts .?
Best ticer .Fantastik IT man
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)
The hot glue technique was fantastic. I’m definitely adding that technique to my future projects. 👏🧠👍
I have the same laptop 😊 white the same problem, now i can see whats going on.... Thanks man, you are crazy-inteligent 😁😁😁
How can I charge laptop battery like you did in this video ?? what did you use
AoA! You are a very Honest Person! May Allah grant you more than your expectations! Regards
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
200 IQ how to test battery thank you so much
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
Its ok if I charge the battery with a 12v 5A charger. Another option is 12v 2A. Which is better. Thank you.
Shot brother clever when you drilled a hole in each end I thought well why didn't I think of that
what if i dont have that tool to charge battery?.. any solution or any way to charge the battery to any tool??
hello sir how can find compatible mosfet in other board?
Hi There,
I was using my laptop on gaming... and suddenly my laptop switched off due to low battery. The battery was hot with ~60C
I let it cool down the temperature and tried to charge again and it was showing o my HP ZBook 17 G2, Baterry Failure alert.
I have replaced the cells that were 0mv, with new cells the battery is charging but if I remove the power cord it goes off.
But it says battery 100%. What can I do? Thanks in Advcance
I have a problem on my hp 530. I plug the charger, but laptop says Pluged in but no charging. I checked with the multimeter and problem is next. Chargers output is 18.5V, and 3.5A. When charger is pluged in, without battery, that is the voltage i get on dc connector. But when i put battery in laptop, i get 17.5 volts. And when he says he is pluged in and charging, percentage of my battery drops, doesn't go to 100% full. What can be the problem? When battery percentage drops low, i can hear some buzzing inside of the laptop, and it's not a fan that makes the noise. When he starts buzzing, also the screen start to act like he is loosing power. Something like.mini flashing. And also, i can't make laptop works only on a charger, he shuts down only after 10 seconds. When i connect charger and battery together, he works, until he drops percentage of battery on minimum and goes to the hibernation mode. I tried other charger, and i got the same results. When fully charged, battery works more than one hour, so i believe she isn't a problem.
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 .
good show
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..
You da man, Sorin!
Still very helpful in 2024. Thanks!
Thanks sir
OMG you are amazing Sir
you are the best
I have HP pavilion c15 the battery is fully charged 100% but when u unplug the charge it shutdown completely, but it use to say the primary storage capacity of the battery is low 601 error code .but a week ago it can stay for like 40mins .
So I removed the battery cells and charge it and replace it back.after replacement it charged full but can't stay on
Hi thanks
