URGENT broken adapter or broken latptop

I was watching a youtube video when I realized that my ac/dc adapter was un plugged from the wall and grounding unit. I plugged it back in and my lapto pl froze then made a loud buzzing sound. I imeditaly turned it off and on, there were 0 probelms. Then, when I made sure that my power cord was workin g, I plugged it in and nothing. When I remove it, the screen flashes black for about 1/5 of a second this is only external. I don't know if my adapter has been fried or the power component in my laptop has been. I am rushing this post because I only have 17% left on my latptop and this is the only d evice I have. I am backing up everything and I also ran power diagnostics. Please, if you have any information on how to check if one is broken or the other, respond immeditally. Sorry for the bad post, but time is limited. T omorrow, I am going to try and build a charger (usb) for it with some extre mely low output batteries and capacitors 130maH in total. yes, I am on it now for those of you who are "slow".

a multimteter will tell you what's coming out of the psu. junk snipped

It's hard to get a connection to the interface between the PS and the computer when it's plugged in. Measuring the PS unloaded can tell you if it's dead, but not much else.

It's the first thing I'd do. What's the first thing you'd do?

Probably the first thing I would do also.

With some of the multimeters less than $ 10 everyhone should have one and have a basic idea of how to do simple measurments.

While it would not tell if the power supply is working, it will tell if it is totally dead or maybe if the voltage is way too high or low.

An ohm check across the primary of the supply could tell if it was bad, but with the moden supplies it may not.

Some of the switching supplies may not show a voltage if not under load, but still that is where I would start.

I read this occasionally, but I have never come across an SMPS that will not run without a load.

I have come across some that show overvoltage with no load, however.

If they latch into a shutdown mode from overvoltage they won't. Actually though in practice the output filter stays charged for quite some time so you have an indication that it DID run. (unless it crowbars the output)

Don't most PC power supplies stay off until that one pin is grounded on the 24 pin motherboard connector? True that isn't exactly what you were talking about, but it might give a novice the impression the supply won't start without a load becasue unplugging the load shuts down the supply.

I get that.

I still have experience of SMPS that DO produce overvoltage with no load, but are fine when connected.

That's the first thing I'd do too. BUT If it measured the correct voltage, I'd put a load on it and look at it with a scope. This is FAR EASIER than taking the laptop apart, only to find that the AC adapter was bad all along...and you broke a bunch of the plastic snaps trying to pry it apart. Been there, done that.

Make DARN sure the power supply is good before disassembling a laptop.

In ANY diagnostic situation, you start asking questions to determine the diagnostic tree. For each question, ask yourself, "What am I gonna do with the answer once I have it?" If you can't do anything with the answer, it doesn't help to ask the question. You can lop off whole branches of your diagnostic tree. If your lack of test equipment lops off ALL the branches, you're dead in the water. Fixing it will be a matter of luck.

In this case, if you can't load the power supply and look at it with a scope, you have two options.

1) output voltage is not correct on the multimeter.>> laptop ac supply is probably defective. 2) no load output voltage is correct...and you don't have a scope>> you probably shouldn't be taking the laptop apart until you have more info or a known-good power supply.

"my laptopl froze then made a loud buzzing sound" is NOT a good symptom That it didn't buzz next time suggests like the power supply is defective and it blew a fuse or something inside the laptop. Or that a static zap killed it when it was plugged in. OR...OR... In that case, trying a good power supply may not fix it. And if you fix the inside problem and plug in the bad supply, you may break it again. Been there done that.

I don't know if you have any repair resources near you.

I'll tell my story.

I had a laptop with a bad power jack. I went on youtube and watched videos on how to disassemble this brand of laptop. It's a daunting task, they aren't made to come apart easily, and that power jack is very vulnerable.

And then, before I did it, I took the laptop to Staples to their "free diagnosis" desk. They connected it to a universal power supply, one of those that comes with several connector pins. Surprise, it booted right up and charged fine.

Even though everybody I talked to was sure it was the laptop, the power supply was the actual problem. All I had to do was buy the new supply.
