My Toshibe Laptop power brick Is buzzing? Please help.

2 10 January 29, 2018 at 09:27 PM
Hello, I'm Elijah Fry.

I have a question for you.
So recently, My power brick started buzzing and wouldn't power my laptop. I saw a few different articles saying Its faulty. I highly dbout that's the case. I swapped It out with my backup. It kept buzzing. I swapped It out with my sisters. It kept buzzing.
I tried all 3 at different outlets. I tried most stuff that was recommended. As I said, I highly dbout Its fault due to me swapping It out with 2 others. The chances of all 3 power bricks dying at the same time I think Is Insanely rare.

All of the things I tried aside,
I had a few different Ideas. My power brick sits on the floor. Apparently, someone In my family dropped a blanket on It. It was a little bit warmer than normal. I was thinking maybe It overheated? As I said above about how It wouldn't power my laptop. I let It sit for about 5 minutes. Plugged It back Into the wall outlet and my computer. It started powering my computer, However, It was still buzzing. At the time I'm writing this post It's still buzzing. It's very quiet. If you put your ear right up to It you can hear It buzz. Some people said It's due to a heavy load. I was playing games such as Roblox and Minecraft. I wouldn't consider Minecraft nor Roblox heavy loads to the laptop. I'm not sure what It Is. If anyone has tips please let me know. Help Is much appreciated. P.S.: This Is a laptop power brick.

Best Regards,
Elijah.

My wife's Dell laptop adapter buzzes/clicks. Almost sounds like an HDD some times.

That thing is like 8 years old no issues.

As long as it's the OEM (not a 3rd party one) power brick and it's physically ok (No cracks in the case, no exposed wires etc) it's probably safe. Power supplies tend to work or fail, not much in between. Coil whine is a common problem with electronics and there isn't much you can do. You might check your input voltage and power quality to see if anything there is off significantly.

Just make sure it doesn't sound like arcing, doesn't feel overly hot, and isn't smoking. It's not likely to be your issue x3. I had one of the PowerBook chargers (made by apple) that went up in flames 10yrs ago.

Why do conservative politicians oppose conservation?
Have you ever stopped to think the long-term GOP immigration policy might be to make the United States of America a less desirable place to live than Mexico?

Wasn't that a recall?

I don't think there actually was. I know there wasn't at the point mine started sparking and smoking. Apple is good at dodging blame. Luckily, I was awake and using my laptop at the time and I was able to react pretty quickly.
