I had a similar problem on my laptop (same model). and internet forums suggested my charger was broken. I assume (now) the motherboard was frozen, because when I unplugged and replugged in the battery, my charger charged the battery again. thanks to videos like this, I saved a little bit of money, saved me from a lot of headache and learned a bunch. Thank you very much.
EXCELLENT DEMONSTRATION of why the Lenovo ideapad was not working and showing that it was working after fixing the non-charging battery. I'm *VERY* IMPRESSED. GOOD JOB: CONGRATS!
This solved my problem: exact same model lappy, I just unplugged the battery and plugged it back in, and the lappy came back to life. Must have been a board freeze. Thank you! Great video!
Another great video! I've learned really a lot in one week by watching your videos and I refreshed all my knowledge once again thanks to this channel! Best channel!
No low voltage protection. Battery is dipping some how. Battery will not accept charge with the laptop charger. It needs a spike to resume taking charge.
I bought a brand new Samsung phone on E-Bay very very cheap :) It would not come on, would not take charge. It had been left on till the battery ran completely flat, the store where it had been on display tried to charge it with a 5V charger to no avail, so they sold it off as faulty. I simply plugged it into a genuine Samsung Fast Charger which is 9V+5V and after one week ??? yes, one week, it came back to life with battery full. Lithium batteries are supposed to have controllers to prevent over discharge but clearly on some devices the manufacturer cheaps out on this protection circuit and the battery goes past low voltage limit and won't charge from the standard charger.
Hi. I have the same issue with my laptop as of now. I've been using my laptop for 3 years since we bought it and ot works perfectly fine. But the other day, the battery was drained because my charger's cord was broken and. And so.I bought another charger the next morning, not an original.one though, and when I tried it at home, it says charging but not increasing the percentage and remained at 0%. Then after a while, it turned off and the charging light no longer works and the charger as well doesn't charge my laptop. I asked the computer repair shop where I bought it and he concluded that the motherboard was affected. Hearing from you that the motherboard is not really affected, and you showing the laptop makes it clear to me that mine has the same issue as of that laptop.
Hi sir, I think you are doing a tremendous job with the electronics repair. I just want to ask if you can explain using a schematic diagram of the board circuits. thanks
It happened to me often on old phones when i tried to turn on and being so low battery freezed...don`t work until let some minutes to charge turned off.
What I think is the battery was too low, taking much current, the charger can't deliver enough voltage to power the board, because it was fighting to deliver energy to the battery, ence the no lights in the begining.
Seen this with mobile phones where you dead the battery. And you need to use larger amperage charger than that came with your phone. To start the charge cycle.
Hello Sorin, thank you for your informative and useful diagnostic procedures. In short, first check if the power supply voltage is coming to the board and look if 3.3v is present at the power button. If it is present super io will try to boot and the other voltages like 5v, ram voltage, core voltage should be measured. If one of these voltages are missing either there corresponding MOSFETs or caps are broken or check if you get 3.3 on gates of the MOSFETs. If there is no 3.3v on the gates, super io chip is bad and must replaced. For the MOSFETs can I use different manufacturers than the used one? Package size and pinout must be the same and also n or p channel types. Do you have a list with most used parts in laptop repair??? Wish you all the best and I thank you very much!
Hello dear. You are doing really very great job. I learned too many things from your videos. I want some information. I recieved one board. And i found one 5 colored resistance is short( black, green, black ,gold, green). And i didn’t found the same resistance. Now what resistance i can use there? Can i use 5 colored resistance? And which ohms?tanks
I had the same issue with a DeWalt 18V lithium battery. I bought a genuine DeWalt adapter to allow me to use the slide battery in my older tools - but the older tools don't have over discharge protection built into them like the new tools do. Result was battery over discharged and would not charge again. The fix is to split the pack and apply a 9V tickle charge from a power supply and put in enough charge to take it over min level, and then the batteries charge fine again.
So i actually have one of these machines and as i upgraded to a thinkpad, this one sat for a while. I go turn it on after i see this video, and the EXACT same thing happens. Clear design flaw hahaha
great repair sir... i have a concern about acer aspire e5-473g-31dv power on but nothing on the screen even the processor will not gitting hot i notice the fan was spinning so fast any idea about this problem sir? tnx more power have a blessed day...
Hello my friend. I have a Lenovo V470C and the motherboard has just gone. I also have a Lenovo G480. I replaced the HDD on the G480 a few years ago and just bought a cheap one. The HDD on the V470C is actually a better quality and runs much quicker. Do you know if I could strip the V470C and use it in the G480 or are they not compatible. Thanks?
Dear Sorin! Do you (or anybody here) have experience with Lenovoa Yoga not charging issue? Turns on, in the first few seconds it shows the charging icon (Windows 10) animated as charging but not really charging. Tried every software method, replaced motherboard, replaced battery and DC jack. Have read hundreds of forum comments worldwide on this, everyone has only the problem itself, no solution. Lenovo Support cannot say anything for this. That is an X-File.
azucho98 The battery was too flat, but the charger should be able to put out closer to 5v than it was, yes some cable voltage drop but i think the charger is not up to spec any longer. That machine seems a bit picky for it to charge the battery, the nearer to 5v the better. :-) Ooow love the dancing penquin :-D
R V Yep the charger is not quite as good as it should be, that machine needs as close to 5v as possible under full load. Ordinary laptops have a wider voltage range so the supply can drop more than a volt and the charging system wont give a dam. Just my opinion of cause.
Don't call it laptop. It's a tablet with integrated keyboard, a joke. It can't be normal for the original (if original) charger to lose 0,5V when it should provide 4A max @5v. The charger is weak or a joke like that "laptop".
Hi, I have a Dell laptop corei5 it has a problem once close the screen and open it again does not return back to work as a normal laptop in addition black screen but you can see the led and hear a fan of CPU still working sometimes leave it then if the screen went to sleep it will not return back till I switch it off with press on the power button and hold a couple of seconds can you give me your advice, please
hi i recently used a different power adapter to charge my lenovo miix 300 because the adapter wasnt working and it was too much voltage and now my ideapad/tablet/laptop , whatever you want to call it will not turn on or even show any kind of power. can you tell me if there is any way to a) fix the problem b) is it the motherboard or the battery c) is there any way to save my data if the motherboard is fried? thanks

Hi Sorin, I wanna see more Phone repairs and microsoldering! I am getting from you new technical ideas.
there are tons of videos on this channel with microsoldering and phones repairs.
Thank you Sorin for a nice video
This is the first time I’ve been seeing such a laptop with a tablet hardware
you are the best teacher and generous person while you share you life time experince with others for nothing
Thanks for another video. Hoping for more tricky faults that require circuit tracking with schematic.
No low voltage protection. Battery is dipping some how. Battery will not accept charge with the laptop charger. It needs a spike to resume taking charge.

I can second you on that. Work is happiness. 🙂 I am also between computer repairs 😣

You are a master !
Hi sir, I think you are doing a tremendous job with the electronics repair. I just want to ask if you can explain using a schematic diagram of the board circuits. thanks
This kind of problem is often found on phone battery, now a laptop have this problem too. Nice
When people goes to mother-in-law house for a visit and they forget their device , this kind of things can happen :)
So basically the battery was so low it wouldn't accept a charge?
It happened to me often on old phones when i tried to turn on and being so low battery freezed...don`t work until let some minutes to charge turned off.
Thanks old man i did it
great job Sorin , why not use the new power supply you order and show us how to set the current and voltage on the next video. THANK
How could someone quick charge the battery like this without all your tools? I only have a multimeter on me
What I think is the battery was too low, taking much current, the charger can't deliver enough voltage to power the board, because it was fighting to deliver energy to the battery, ence the no lights in the begining.
Plus the fact that the battery was super drained , 3.05volts ain't healthy
So how do you charge the battery when it gets too low
Very very informative video !
Seen this with mobile phones where you dead the battery. And you need to use larger amperage charger than that came with your phone. To start the charge cycle.
Thanks it worked on mine 😊

So if the battery voltage is too low could be the issue? I have an ideapad 330s with the same problem
I would still mistrust the capacity of the charger, worn output capacitors.
I have seen this too many times.
I was thinking the same thing. Cant handle the load and the voltage drops.
It wouldn't power on with his bench power supply either so how would you explain that?
