- Recently one of my Dell notebook computers experienced a catastrophic failure to the power supply/battery charging portion of the circuit board. Rather than throw away the computer, I found another way to power the computer without having to constantly recharge the battery. Enjoy the video!

this repairability is a reason why I am not supporting Apple products!
Couldn't you have reduced the voltage of the original switching supply to 12.8v instead of using an alternate power source? or does it not produce enough current? Also, and I'm not sure about this, on this particular laptop, but in many cases, you can enter the BIOS to turn off the battery fault detection in the settings, to escape the recurrence of the battery error message at bootup... just a thought...
Pp Ss I could have bought a step down converter, but I hate to buy things when I have other things on hand. I'll check the BIOS...good idea.
Hello and thanks for your video. I just tried this on an old laptop. Only connected +11.5V and 0V pins (Battery is rated 11.1V). But when I press the power button, the battery led on the motherboard flashes three or four times and then nothing. I saw on your video that your connector has some other connections or jumpers. Is it possible that I need to connect something else besides the power pins? Thank you.
Either your laptop isn't getting enough power from the power supply(very likely), or the computer won't start up because it doesn't recognize the incoming power.
i tried it and its not work battry light blinking which means amp are low so i connect to 12v 5amp battry still its not working help which wire you short to work ?
YES SAVE MONEY POWER SUPPLY 64$ :)))))
All the laptop AC adapters I have ever seen are a nominal 19V @ about 4.5 amps. Are you sure the AC adapter is not bad ? I assume you load checked your AC adapter. Maybe the battery is bad and is pulling down the power rail when you plug in the adapter. Did you try just running the laptop off the AC adapter with the battery removed, You can run a laptop without the battery installed just off the adapter. You may be right that the internal power supply / charger got fried and this is a great work around.
JOHN LUCAS 100% fried.
You can't use the original power without lowering the supplied voltage (it has higher voltage output in order to be able to charge the 12V laptop battery)
why not use the original ac adapter again? I just put whatever fits into the hole. I only check voltage if i take the end to put it in another power supply. usually works for me.
Trench You don't understand. The old switching power supply is fine, the portion of the circuit board that handles that power was fried.
@@electronicsNmore have the same with acer laptop but I don't know how to connect power
( Always at desk ) Plug in Power > go into Windows > Device Manger > disable Battery or put Power supply as the main source of power supply ( can disable Battery)
Few Videos about this Unplugging battery Inside laptop - if you never leave desk power Always boots from mains power
Buy a PC .
It would be interesting to see the motherboard to find out what died in it :)
The Tired Techie Wish I had the extra time to do it.
I'm suspecting it's only power brick connector on motherboard or something before the power management chip, usually not a non-repairable fault.
Can you purchase an external battery like the omni 2000 to power the computer? I'd like your input before shelling out 200 bucks.
If you can get the computer to work doing as shown in this video, then you can switch to a battery later. The battery must have the same rating or higher.
Nice one, Subscribed. Please keep'em comin...
Can i use inverter battery instead of power supply
So I tried 12v and 4.5A but my laptop didn't power on
Should I make the current 5A?
Make sure you are definitely using the correct pins. It's possible you may need at least 5A.
I want to know sir the inserted 9 pins connected from power supply to battery terminals...
Every laptop is different. You'll need to identify the correct pins for your laptop.
Can you please give me the link of that battery connector? Please. Please. Please.
Excellent video! Valuable information presented in a very nice, simple, concise manner. Good voice, tone and communication style as well. 👍
(Just wondering have you tried in increasing the power supply gradually in 0.1 volt increments, i-e, 12.7, 12.8, 129. ... 15 volts). I have a strong feeling that it might work on higher voltage range as well because with same motherboard, some laptops have 4S instead of 3S. Pls try and let me know!)

Doubt if the 13.7 volts would have fried the 12.6 battery and nominal computer value needed for power.
No, just keep the voltage at a similar level to the battery pack.
Edit 3 I saw something about drawing less amps without dvd drive? If I remove dvd drive I can use an adapter with 3 amps current?
Edit 2* sorry I’m reading through the comments seeing you’re getting a lot of similar questions, I see you put less than 12.6 volts and 4-5 amps SHOULD work but stick close to MY specific battery output specs... Hello I like your tips, do you think I could find a universal adapter that’s close enough? I don’t have a bench supply. My battery output is 10.6 volts, not sure about the amps. I found a 12 v adapter but it’s only 3 amps current. I noticed you said you had 4.5 amps and needed 5 to power the laptop normally? Wondering if a 12 v adapter with 5 amps would work for me? I know it’s hard to say for sure but I really want to get this laptop working. *edit* the laptop is powering on with everything working except the screen. It’s a gateway nv53...hmm
My dell has same issue , thanks for speedy response & great idea .
My dell laptop charger is good but when plugged in for charging the LED indicator for charging is working or light up
My laptop is latitude e6430 I want run on 12v can you tell me is it working and send me diagram plz
one less piece of tech in a landfill. you are doing god's work
I have the same issue but with different laptop, can you explain more to me at what you did?
I bought a new battery for my Alienware, didn't fix the problem so I purchased a new power supply, still doesn't work, tomorrow I'm going to try this and let you know if it works :) My power supply is huge, 19.5v and 20 amps. The battery is 14.8v. So I guess I need a power supply of 14.8v and at least 5amps? Does that sound correct?
13.5v to 14.8v at 5A should work.
@@electronicsNmore Amazing it works!!! HOWEVER it only works with the power supply still connected? Even though the power supply is NOT charging the laptop?? So now I need two power supplies, one connected to the battery side and the original Dell charger in the side of the computer!!!! Any walk around for this? I will be using a large battery from my boat (300ah) and dell charger plugged into my inverter !!! Any advise or help would be most welcomed !! Simon
Im having the same problem and i did everything like that but my laptop's power button is just light up then off again ( im not even touch it ). Im using 12v 5a supply.
Same thing happened to my wife's HP laptop. Our son uses it more for gaming. Before I saw your video, I purchased an external battery charger for the laptop battery. That works but what i'm wondering is can I use that external charger to power that laptop by changing the end of it to fit the computer instead of the battery? In otherwords, does the external battery charger act (or can i use it) like your Trip Lite DC power converter? I don't know much about electronics.
I always thought this must be possible to power a laptop like this, but I've never seen a commercial product that did it. This is a great alternative DIY solution.

Bro you came in my life like a angel my laptop volt in section died i was finding out the exact stuff
If it worked it will be a great help
Did it work ?
Thanks! My old Dell laptop works fine, but gives only 2.5 hours on 65Wh I'm gonna use your input to create a pancake 12.8V LFP solar charged stand or similar.
Very helpful well made video. My battery is showing very low and not charging. Unit works OK from the power pack which is showing rated output Volts. The cells are not flat and can discharge at 10A. Since there's a fair amount of electronics actually inside the battery, I'm not sure where the blame lies. I can't measure any volts at the supply pins with battery removed and Laptop powered up. Maybe it detects its absence and switches off...??? Any ideas or help would be welcome. I'd really like it to be portable so battery operation is desirable. Best regards BjG
My laptop it's same problem. ..thanks for sharing your idea
demha yawanekla It happens. :-)
Excellent idea! This is JUST the kind of workaround I have been looking for. I have an old 13" MacBook A1342 from 2010, with a broken DC-in board, where you connect a Magsafe charger, that supply 45 or 60 or 85wats. Everything Apple is expensive, so i want to use what i already have. The battery that is labeled 10.9 volt should give max 12.4 v at full charge. Well, this battery is dead, wont charge. I have a 12.2v power supply but i am not sure how to connect since Apple has built in different chips both in motherboard and battery to communicate with each other. Any ideas or tips?
Hi Erik! That's the nominal voltage, 12.6 is the fully charged voltage. A 12.2V supply is perfect, as long as the current level is high enough. You can always rip open the battery pack, remove the cells, and connect the power supply (+) and (-) to where the battery was connected. Good luck!

@@electronicsNmore Thanks for the reply, but sadly it seems it wont work. From what i read online, Apple put some "electronic fuse" or something inside the battery, and if, for ex, the voltage inside ever drops to a certain low (because a cell go bad), it blows the fuse, and the circuit is broken and even if you replace the cells, it wont work. Same then if I put DC in instead of the cells. VERY frustrating.
Update: I found a workaround to make it work! With Mac-laptops, you need to use "bypass SMC-mode", or whatever its called, (disconnect all power, hole power button 10 sec, connect power, keep holding power button 10 sec, then release, the press power again). Then the laptop powers up, on 12 volt DC in via battery plugg. Now I am here to find out how to do this on an old HP/Compaq laptop where I have no battery, so its a bit difficult to figure out pinouts....
Hmmm was the original PS only 12 volts??
I’m guessing is 19V and that’s why you are needing so many Amps.
P V Draw off the battery without the DVD operating is around 2.5A. Original power supply was 19.5v, which ran the computer and charged the battery at the same time.
Hello I have a Dell laptop battery model J1KND 48w 11.1volt How can it be charged without a laptop? Which pins are negative and positive? Can its negative and positive pins be used as a power bank?
Well now i know whats wrong..an i guess i will get half ripped of by some old fat guy at a comp. store front...I wish i had the equiptment. You have to workaround magic..I have two power supys for a rasberry pi and a panda latte wonder if i can use it? Anyone know?
You need to see how much current and voltage the computer draws.
Hi thanks for the video. I been looking for an answer. Just have a question, the battery says 10.8 v , I guess it should be around 4.9 amp. Would it work, taking aout the DVD player, and using a 12v ac adapter 3.74 amp?
You need a switching power supply of no more than 12.6v that can supply between 4-5A.
@@electronicsNmore ok thanks for the fast response:) So the same power supply as in the video will do.
@@gaal-guirestaurant6888 No!
@@electronicsNmore pc power supply will be ok?
It works but im getting electrical socking i think due to not grounded. Do anyone know how to fix that?
hi, does this work with any cables/wires?
my battery is an internal one and uses very thin wires. I wanted to keep the wires and the little plastic connect outlet to fit it into the board no problem, so I soldered on some wire with about the same diameter but it's made out of one solid metal instead of those fibers. would it still work? does it have a higher resistance or anything? also cable wires are thicker than these so would there be a problem soldering them onto a charger with normal cable wires and the right voltage and current? should I be worried about something catching fire?
Thanks man you saved my money

My dell charger has its ID chip fried. This has two consequences: 1. no charging, just maintaining the voltage; 2. setting all CPU cores to minimum frequency without any way of bumping them.
if someone can share the pinout diagram, I appreciate!
They all vary.
Hello, Cool video. I have a Dell Inspiron 13 7000 series 2 in 1 laptop that the power supply port/receptacle broke off of the motherboard. I can’t find a motherboard replacement that I can afford and wondered if you know of a way to power the the motherboard via a USB-a port or any other way to power the laptop and keep the battery charged? On the machine I have it requires taking the bottom off to access the battery or I would go that route. I would go the route that you used but I need to move the laptop from place to place. Do they make a USB-a charger or adapter that can recharge the battery? I am at a loss of what to do, being a disabled senior on a small monthly income I can’t afford a new motherboard. I have tried a couple of used MB’s from eBay and both would not work so I am afraid of the $129-$179 used boards.
With your knowledge I wanted to ask if you may have a solution. I feel if we can put a craft on Mars there should be a way to charge the battery without taking the computer apart every few hours. With as many computers out there without a USB-c port someone should develop a way to charge via the USB-a port and make a fortune. Thanks in advance for your input it is greatly appreciated.
Excellent work.
I have a big Dell laptop/workstation that was acting up (couldn't play audio properly -- the audio kept sputtering, like the system could not keep up). After reinstalling the audio driver too many times, I discovered that if I let it boot while on battery (i.e. charger not plugged in) it worked fine, but if I booted it while plugged into the Dell charger, it would not run fast enough. It turns out that that charger was too small (in Dell's view) to run AND charge the laptop, so when the BIOS detected that, it crippled the clock rates to save power to the point that it could not even play audio.
At some point I had told it during boot that I didn't care about the charger was too small, and after that it never showed the warning that the system would be crippled.
Booting while on battery, then connecting the charger was a good workaround. Also, getting the proper charger worked.
Hey ive had the same issue and i tried this..So i used an alternative power supply of 5A 12v.. to find the third negative in the laptop pins i looked at the battery and there was written all of the uses of pins so in mine the third negative was just alongside the 2 negatives ..... so can i just connect all three together and provide negative charge and the other two end pins the positive?? please reply i reallt need your help
hi..bro i have dell latitiude e6320 but this method dosn't work on my laptop plzz help
What is the voltage and does it harm any inside components of th he laptop???
Damn i need this 4 my asus mb ver x501
Hi, can you tell me why not every battery can be meassure? For example i have 2 batteries that does not show any voltage on output, but once you add them to laptop, everyting it's fine. But right now i have other problem. Hp 6530B, i don't have any output voltage on laptop's pin. Not battery, but on the laptop. There is no voltage to battery. But if i add the battery and i meassure the pins inside, there is unstable voltage 0 to 13 volt. Once you remove the battery it goes to 0.50.
usually if the battery ran out once (eg: in storage for too long) the protection circuit think something is wrong and disable the whole battery.
I have the same issue with my Samsung laptop. The laptop worked a month ago and randomly it started smoking and stopped charging from the charger because the charging port is broken, so do you think replacing the port will fix it or is it something else like a chip causing it to smoke? I'm a little worried since the laptop still worked before the problem and was pretty useful although it was 9 years old. Of course I have another laptop but I don't want to waste a laptop unless it's fully broken...
Without looking, hard to say.
Can't we use ripped power brick/charger instead of power supplier?
Will it be steady and enough power?
My laptop works this way but shuts off after 10 seconds... probably some safety function of the laptop when it’s detecting the non original power supply. Do you think its fixable?
Probably lacking power to keep it running, try another power supply 1A higher. You may be able to adjust some BIOS settings.
electronicsNmore hey thanks for your quick reply. My power supply is a multi voltage powerbank rated for 90W. I found that when I bridged the temperature sensor pin to ground it works... so perhaps this is a PTC sensor where the resistance increases with higher temperature. So not grounding it will tell the laptop the battery is too hot and it will turn off? Anyways It’s working now. Thank you!
Nice video

Quick question are you keeping the small circuit board attached to those pins. would it work just applying your voltage with no circuit board directly to your pins? Thanks.
The power is connected to the board that was used for the battery.
@@electronicsNmore okay perfect thank you. unfortunately I took my pins off of the board not sure if I can put it back on. what would happen if I connect the power directly to the pins with no board if the voltage is being inputted to the pins at the same level. I'm assuming the board with all of its diodes is used for the communication pieces of the pins would this be correct. And if this is correct does that mean I can connect the power directly to the pins.
Hi I just did this with my own laptop but used a 500mah adapter 12 volt n it barely switches on then goes off after do u think if I use a 12 volt lithium ion battery pack would that work well
