I'm trying to move the easier hardware stuff there so that I can focus on the more in depth troubleshooting and diagnostic videos here :)

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.

Well discuss. Easy to follow. Thanks for making this video.

Thanks brother i learned from you how to check really am very greatfull to you god bless you stay safe and be happy always... Soo much thanks for this video

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.

Ok ur a life saver!! The last vid I watched helped me so good tysm! It was my charger I Believe

[earthcomedy]

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 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 it worked! Yet, the old/original adapter does not - even though it tests at 19.5V. Not sure what the deal is....

Thanks for your response. Please understand I am a novice with this stuff. I bought a meter tested the power supply it is fine. I watched your video on testing the receiving Jack in the laptop. There is a ribbon cable over it and I am not sure how to unplug it to access the Jack to test it.

thankyou!! saved me a lot of money. turns out the plugs breaker was thrown. I had to get to the level of testing my electrical though. its a new combo plug with its own reset. the discouraging part is that it has a light on when the breaker is thrown but that mean no power.
