In addition to testing your charger's voltage, you also need to test its current (amps). It's entirely possible for a charger, or any electrical device, to be putting out proper voltage, but little to no current. Testing for current is an entirely different animal than testing for voltage.

[@kitto6063]

Well tell us please!

[@Elpipiton]

Entirely different animal lol no. If ur getting voltage, and the load isn't doing it's thing....replace it.

thanks to your video...was able to fix my machine from not charging! I never thought it could be the AC Adapter that was the problem. Before looking at that, I replaced the internal battery, which for a long time was drained - I would get a startup warning msg, but I just ignored it. Then one day it didn't work anymore..... the new battery wouldn't charge - but it did power up the machine until it ran to zero. Thought maybe I got a dud and was going to exchange/return it. Then I saw your video. I tested my old/original power adapter and it shows 19.5V stable on the multi-meter...but I had already ordered a $12 replacement adapter on Amazon. Thought, what the heck - I'll try it anyway.....and it worked! Yet, the old/original adapter does not - even though it tests at 19.5V. Not sure what the deal is....

Amp?

[@ProjectDreamCatcher]

VERY IMPORTANT - just incase they want to check other chargers you should tell them about the little symbol on the back of the adaptor that shows if the possitive (+) is in fact the center! Some are reversed (+ on the outside). Things can seriously fry if you're not sure. I think you are safe using the meter though? Thanks for the video.

It will work fine if the cables are reversed on the multimeter

[@user-ti5fd3gs8z]

Multimeter i guess has that kind of protection

[@Loduwijk]

​@user-ti5fd3gs8z not protection, it just reads the voltage normally which is now negative since it's reversed. In this case you can just ignore the negative sign.

...but theoretically the power adapter could be putting out the correct voltage but not the correct amperage. I am trying to test amperage because I have two new batteries neither will charge but the charger indicates the correct voltage. Could be two bad batteries, granted as this is an old camcorder and the only batteries on the shelves are years old (even though the seller assured me they were made in the past year).

Hiii. For example 2 of them showed bigger values than mentioned on the multimeter. For example one with 5 volts appears 9 on the multimeter. What could be?

[@AquaticSkipper]

My laptop adapter is 11.8A output, should I use a multimeter with a 10A option or a 20A option? Or does it matter? I notice you use the other option for power on that multimeter, why? You dont explain that choice. If your multimeter was in "10a mode" for red, would that prevent you testing amp outputs either below or above that maybe?

I bought an 18v 1ma Psu for my audio mixer and it started smoking inside the mixer. I did your test and it’s putting out 21v but it’s labelled 18v … I’m assuming this isn’t correct and why it’s smoked ?

[@davidpride590]

The wire end near the connector can be worn inside but still show voltage plug in the computer and wiggle if you see the light go off or flicker at the same time you bend the end right near the 90 degree plug end that is your issue you can repair solder but if your really desperate sometimes a bit of cable surgery and an alligator clip or even a paperclip can make the repair if your not worried about a fire but it is low voltage DC. If there is poor connect some laptops will flash the charge lights or just shut off, if you enter safe mode or the bios startup mode F1 F2 etc then you can charge without drivers installed or with duplicated or corrupt drivers that the short might have triggered a reset or duplication of or some other internal protection circuitry etc. So it might only be able to charge in this mode until properly repaired by reseting the bios or getting a new charger battery or both but try a different charger at the computer shop first the battery and charger are pretty cheap. I have even spliced a different charger with the same approximate voltage and it works fine for a fair period if it heats up there is too much load maybe not Enuf watts etc bigger is better if you charge 4 cell phones in your USB etc or any extra loads. If it runs without battery and doesn't short u can leave the battery out as charging the battery is the biggest load usually. So unplug any USB loads and the battery plug in charger but leave computer off or in bios boot mode before the drivers load then use a USB load to verify power stays on like a cell phone that dings when it charges if it dings on you. Have a solid charge connection if it keeps flicking on and off you have a poor connection or very corrupted drivers. Delete all drivers and their duplicates From device manager before rebooting past bios start or safe mode if no flickering then it's software related if flickering still. You have a bad connection somewhere check external. First but could be pin in or internal. If it charges off fine then you can only run until the battery dies as the battery power is a different source location but tees in somewhere inside. But it works half the time lol. The charge onky load is less than when running with charge and USB load total a weak Or low output smaller charge cable might still have Enuf juice to run without battery and without major USB loads you can properly splice in a larger charge cord of simular voltage with more watt output on most laptops if the internals do not accept it can. Still charge the battery when turned off. The battery lights usually will turn Color when charged do not overcharge unless you enjoy a good fire always check. For heat at battery and at charger warm is ok but hot is troubke heat indicates load or excessive load like an internal battery short always test in a safe place. Do not. Leave unattended unless 100 percent safe from fire. Solder it up properly using heat shielding or cold solder techniques with proper fire rated insulation etc. If you. Short circuit the charger it can be destroyed quickly with open circuit wires inside the box usually. Not repairable. Get another and test continuity and polarity before plugging it in. Do not reverse polarity usually the pin is positive and the outside wire and outside pin. Are negative DC remeber AC is converted by the charge coil and any electronics inside the charger cable box. Sime even have an led showing DC power out but the connector end can still have an incomplete circuit to the computer or battery charging system. So the volt test is not always accurate but a good start. Enjoy all and be safe

Hi PC Monkey. My ASUS Laptop will not turn on with or without the battery connected.

i got a multimeter but it dont have the line/3 dot 'symbol' THATS ON there , it s on dcv and the other dial is V ma-kn 100........." is that the sam edial? thanks!

[@ericwhudson]

DCV stands for DC voltage. It is the same thing. The main thing to distinguish is that you are measuring voltage (V) not current (A). This often involves both a dial setting (as was shown in the video) and proper placement of the probes (if you look in the video you'll see that the black probe is in COM - common or on some multimeters it will be GND for ground; the red probe goes into V NOT A).

[@jsjoe66]

Hi, the setting on the multimeter that you show is that in millivolts DC or millivolts AC? The setting on my multimeter is V with two lines under it and the charger is suppose to put out 20 volts.

[@ericwhudson]

That is Volts DC (The horizontal lines mean DC, the wavy line means AC). It is NOT millivolts. On some multimeters you need to set the voltage range you are looking at. You want to set it so that the voltage you are looking for is in that range, likely 10-20V or something similar.

1. For a computer that does not turn on, try this video first; kzbin.info/www/bejne/oYClimehZ7Khlc0. Let me know how that goes :) 2. Also, did anything happen before this issue appeared? Liquid spill, overheating, Windows update, etc?

[@SKSK-xe2zu]

Sorry how to check the charger (Pin Head) current leakage. use test pen check?

[@MrGtagangster]

Just to mention something else, the charger might be able to put out the required voltage but NOT the required Amps for the device connected (eg. Laptop). Amps are necessary too! (I hope)

[@PC_Monkey]

Yes, very true. This was one of my earliest videos shot prob around 5-6 years ago, back when I was Pointe Tech. Just havent got around to updating it yet. But its on the list :)

[@enermaxstephens1051]

@@PC_Monkey I would love to see an updated video. One that shows volts, amps and wattage. That way we're 100% sure the power supply is functioning properly.

[@PC_Monkey]

@@enermaxstephens1051 Testing A and W are a bit more complicated than V. You wont find too many ppl on here showing how to test for the A. Im still working out how safely to show it and will post a vid when I do :) Another way to see is to simply replace the charger with one on Ebay, Amazon, or another place that offers free returns.

[@dannijabara]

Yes. Voltage is whats required for the adapter to push current (Amps). It may have Voltage, but that doesn't mean current is there so this video is VERY counter productive.

[@arviejoycecayabyab4280]

Hi, can you tell me what's wrong with mine? When I charge it, the charger's light turns on but it doesn't charge my laptop. Sometimes, I find myself tweaking and turning the position of the charger into my laptop's charging port to find the right position and when I do, it's the only time that it charges. Thanks so much.

[@PC_Monkey]

If you have to move the angle of the adapter then I would think that the power jack in the computer is damaged. That may be the cause of your issue. If so, you may need to replace the power jack board if its separate from the motherboard. If not, replace the motherboard.

My laptop turns on only with battery but with adapter it's shows ac adapter type and wattage can not be determined your battery may not charge. I have checked adapter same as you told and I found that adapter output is same as my laptop. I didn't understand where is the problem. Sir can you tell me what causes the problem?

[@PC_Monkey]

That usually means there is something wrong with the adapter or your software. You can see how to fix that issue here; kzbin.info/www/bejne/opO9eYeZfNt_nKM

[@jlr1487]

@1:57 you insert the red tip inside the pwr adapter; its unclear to me exactly where, I think you say "wall". Does that mean all the way to bottom end, or just internal sidewall. Thank you

[@PC_Monkey]

Each charger cord is different. If there is a pin inside, you would put the red probe on that and do not touch the inside 'wall' of the charger pin

[@jlr1487]

@@PC_Monkey Yes, there is a middle pin, but meter stays on 0 on it. After a few tries, It does display adequate voltage on inside wall.

[@sophiabuckner5471]

The probe on our multimeter doesn't fit into the end of the charger. The probe is too big. Is there another way to know if the charger is broken?

[@PC_Monkey]

The only way I have ever done it is by using a multimeter. I just did a quick search on KZbin for the issue and found only other multimeter videos :( Perhaps get a smaller probe is all I can say :( Or, if you have electrical skills, open the end up and test it. But in that case, it may be worth it to buy another charger instead of dealing with the hassle.

[@shaunsaju7084]

I have msi laptop ..my dc output varies from 16-18 v ...but it is rated 19v...my laptop is not charging..but when I keep the cable in certain positions it charges...also the cable heats up a lot...is the problem due to my connector cable ,my adapter or my laptop pin? Pls help.. thanks in advance

[@PC_Monkey]

I would test the charger as seen here to confirm its healthy. It also may be your power jack, as it needs to be at a certain angle. The jack could be damaged. If the charger is heating up severely, however, I would guess it needs to be replaced. Do you use your computer with a surge protector? You should.

[@viruantala1183]

Hi, I wanna buy new laptop . Which one u suggest ? Now I am using lenovo I7 please guide me to buy new laptop for my personal use

[@PC_Monkey]

There are many laptops out there. It depends on what you need it for and where you live as not all computers are sold everywhere. What programs are you planning to use?

[@wellschaung1110]

Correction. 19 volts adaptor the multimeter reader must read a bit over 19 volt. If it read 19 volts exactly, it may not have enough power.

[@PC_Monkey]

Feel free to do that for the customers in your computer shop lol. Ill stick to this for mine :)

Hey there I got a new asus vivobook 14 laptop last November Around 5 months ago Now its not turning on Not even the lights. There is no shop around due to covid Can't get a multimeter But i do think they are not the problem as they are relatively new Can you drain the static if you don't remove the battery and press the power button for 1 min I am not removing the bottom as it might screw the warranty

[@theScholar369]

@@PC_Monkey like i have commented above. The laptop is new It is not turning on and the light too is not on. I didn't remove the battery as it is not removable from outside. ( as it may be wrong with the warranty period still valid) But i did unplug all the wires and usb and pressed the power button for 1 min and it didn't work. Is it necessary to remove the battery for discharging the static ?

There's a hole a mile-wide in this video! How do you test the amps?

No. Without testing the charger, its just a guess.

I tested my laptop charger. It's rated at 19.5v DC but only outputs around 11v on a multimeter. I take it the charger is kaput? Or is that within an error margin?

Sometimes I've seen damaged power adapters with the right voltage reading, maybe the current could be the problem sometimes

[@PC_Monkey]

Yes, the current can also be faulty in a charger at times.

I have a Tester that Instead only has settings 10, 50, 250, & 1000. Can I Assume I can Still use it, but set at 50 since 10 is Below 19?

Yes, I would assume that would work fine :)

[@kevinbrown8497]

Yes. 50 would be the correct setting. It will give readings (safely and accurately) up to 50 volts.

[@pizzakat]

Hey, can anyone please tell me what happens if your laptop charger outputs less voltage then it was supposed to? Does it keep disconnecting and connecting whenever you open up a high cpu and gpu usage app?

[@PC_Monkey]

If your charger is putting out too little volts, then your computers performance most likely will suffer. The battery may not charge as fast or as all.

[@lolsword7]

Hi PizzaKat. I know you wrote this comment 10 months ago, but I wonder did you find a solution to your power problem? I am currently facing the same connecting/disconnecting issue when playing intensive games on Steam

[@nick-rv8op]

Can you tell me whats wrong with my laptop /charger? So what happens is that my charger doesn't charge my computer but it charges my friends laptop and his charger charges my laptop, i am really confused (btw we both have lenovo)

[@PC_Monkey]

It could by your battery is bad. When you say, its not charging your computer. Do you mean the battery is not charging or your computer isnt getting power?

[@Yash-Gaikwad]

You didn't check the amps. Should you be checking amps?

[@ericwhudson]

Can't really check current. These are voltage controlled power supplies. That is, they supply a constant voltage. When you put a load on them (e.g plug it into the computer) then the supply will need to send out current in order to keep the voltage where it wants to be. If you tried to measure the current just of the power supply you'd be "shorting it" (attaching the +19V signal to ground through your multimeter) and you'd likely end up damaging the supply. DO NOT MEASURE CURRENT from a constant voltage power supply (pretty much any standard power supply). It is a similar effect to attaching a wire from one end of a battery to the other - you'll just end up draining your battery. Except for a power supply, depending on its design, you have a risk of completely frying it.

[@olo-burrows]

True. It could put out 19 Volts just fine for the meter with no load, but when plugged into the laptop a bad capacitor in the power brick could cause excessive a.c. ripple that upsets the computer. Or the power brick simply can't put out the full 4.74 Amps any more for whatever reason. If you can borrow the same kind from a friend to test that would be one test to make.

[@texastitan6567]

Is the charger plugged or unplugged from an outlet during this test?

[@PC_Monkey]

It would have to be plugged in or it couldnt read a charge :)

[@texastitan6567]

Ah. I’m new to multimeter wasn’t sure if they produced their own charge but in hindsight yea that doesn’t really make sense

its safe to do this? i have a 5 volt ac adapter i want to test for a handheld game device.
