Everyone be very careful. I took my adapter apart that hadn't been energized for over a day and it still showed 120VDC across one of the capacitors. That can really bite you! Get a resistor to drain off that charge before touching.

@BarryFence4 жыл бұрын
@@imadrabhi5991 You should discharge it through some resistance or you could damage the capacitor. If you can rig up a light bulb with some leads (that are insulated...) you could discharge it through that... Otherwise, it will dissipate over time, but it could be a few days. If you are feeling lucky, you could use a small insulated screwdriver and just short it out in little bursts but it might damage the capacitor. Wear eye protection, though!

Lucky for me the charger was unplugged (at least I tought of that!).

Great techniques and advice in this video! Thank you! In my case, I saw a failure of both the output capacitors from a cheap $10 power brick (the type that we're advised in the video to avoid). I blindly replaced the capacitors with a pair that has a higher voltage rating, and they also started to fail due to over-voltage; my 24V supply was putting out over 50V! I haven't verified this yet, but I believe the transformer failed in a high-current use of the power supply. It is often the case that these cheap transformers use copper-coated aluminum wire, which will generate more heat due to higher wire resistance; this can melt the insulation around the wires in high-current situations. When that happens, turns are shorted, you get a higher output voltage than expected, and then electrolytic capacitors go BANG. So, yes, don't buy the cheap $10 power brick!

I removed the case and then suddenly the LED does not turn on when plugged in. As soon as I removed the case I smelt something that most engineers would recognize as a shorted/damaged part. I looked all over but couldn't find any damage. I'm wondering if the power supply is rigged to break when opened. Or maybe some cap was shorted during the case removal. Anyway, be careful! Removing the case may make things worse :(

I couldn't get it open and tried with some force but did not want to gouge the plastic too much. I saw in another video to use Flux solvent on the crack all around the adapter. It appears this is Ethyl Alcohol. I didn't have any , I had Isopropyl and used a dish plate and put the adapter on its side in the plate and poured a little bit of Isopropyl into the plate and used an eye dropper to pick up some and put no the other side of the adapter and the ends also. Waited a few minutes and then I was able to break the seam at one point and then I got the screwdriver in and kept prying and used a kitchen knife to slide up the seam to break and just kept working it until one side was open and then just kept moving it and prying until it was free. Then of course you have to know how to solder , remove the top metal shield which was soldered to the board and then I could unsolder all three wires, noting white black and blue locations. Done in about 20 minutes total. I did not re glue the plastic together I put on two black twist ties. I know this will last a few years and then need to be done again.

My AC Adapter is a model PA-90W. Recently it started not working very well and it would need to be at a specific position (the ac adapter itself not the wire). I'm familiar with issyes where there are kinks in the wire between adapter and computer and I'm pretty sure this is not it. Usually the blue LED on the AC adapter is off but when it's on it can be a low intensity blue light or a very bright blue light (when it is bright it is working). So in an effort to make it work I tried 3 things: 1. Unplugging and replugging the triple socket wire that goes from the wall outlet to the AC (this doesn't have any effect anymore), 2. I pick up the ac adapter by the 3 prong cord plugged into it from the wall and I move it up and backwards toward my hand till the AC adapter and wire are upward and tipped back and then set it back down. This also makes the 3 pronged cable slide out and around a bit each time which I'm pretty sure is a part of how this works (this is highly effective in getting the LED light to turn on to the high intensity level and the light on the laptop that indicates it is charging will turn on. However, this is only temporary and the LED light gradually turns off usually and along with the laptop charging light. I believe that the 3 prong cable being not fully in is part of why this works because for some reason it tends to start charging when the prongs are not completely inside the AC adapter) and 3. Just shaking it like in 2. but with my hand around the power brick itself. ^I have been able to get my laptop to continuously charge with all of these things albeit with some difficulty (it takes a long time to work) and I have to keep the AC adapter and wire still because if I'm not careful it may stop charging. At the moment #2 still works and rather well but I haven't been able to get it working again for quite a while. I have not yet looked inside the AC adapter but I would like your advice/diagnosis in this situation. Please and Thank You, sir.
@ElectronicsComputers3 жыл бұрын
First of all you have to check if the AC socket is properly soldered and have a good contact with the PCB. Secondly, I would check the caps and DC cable. The last one could may have a short. You can simply desolder the DC cable and see how the blue LED indicator changes with and without cable attached.

Did not work that well for me - I could get the screwdriver in, but the case did not pop up as in the video. When I turned the screwdriver around a bit, it just widened the hole and did not open the case. Had to ruin one side a bit to finally make it pop open. It's a Toshiba Satellite PSU, by the way.

I've got the same issue with an ASUS. Got a bit careless and jabbed my hand as well, but that's my own fault.

Thanks a lot. Just watched this because I am to replace an adapter's output cable and I was wondering how to open it up. I am not exactly friend of this screw-less fashion in components. Did they forgot to play Meccano as kids? 😒

Hi, first of all great tutorial! I wanna ask about one thing. The LED on my adapter is of and it doesn’t give any power out. But somehow after a while with it’s plugged to power source, it became hot. Based on this, what is your diagnostic on this? Thanx in advance.

most likely you need to replace capacitors and I'd also recommend checking DC cable for short.

"Without damaging" *attacks with screwdriver*. There are plastic pry bars for this kind of thing, they don't leave markings as metal tools do. Just a tip!

Is it possible that the AC adapter still works (and randomly fails) if some of the capacitors are swollen on top? I'm asking because I have a laptop without a battery, and I'm running directly on the adapter. The thing is, the laptop is turning off randomly, either during gaming or just by watching KZbin, but mostly during gaming. Sometimes it turns off after 4 hours of gaming, sometimes after 30 minutes. There is no pattern, but I would like to be sure that it's the adapter's fault before I open it up.

It could be but first check if your laptop is not overheating. Use some software like Aida64 to check CPU and GPU temperature.
@LukaReeson3 жыл бұрын
@@ElectronicsComputers Ah, I forgot to mention, the temps. are 65-70 C when gaming and 35 C when idle (cpu and gpu), so I'm sure it's not an overheat issue.
