Hi Guys,

My volume dial has fell inside my laptop at the front and now the volume isn't working on my laptop, I tried using the volume control next to the clock on the task bar but it won't work.

Does anyone have any suggestions?

It sounds like you'll need a service technician

I think I'd take it to a service technician. Taking a laptop apart and repairing it takes skills that most of us don't have.

Good luck.

volume reading but no sound
by andantesash / February 18, 2013 1:29 AM PST

I have fixed alot of laptops in the past, stripped them to pieces, replaced screens etc. But this just has me stumped, it says its working in device manager and when I go to playback devices when I move the volume button up and down the little green audio bar goes up when I hit the top of the volume button.

Or If I play music, and go into playback to check whats coming out - the volume status mixer is bouncing up and down to the music - but no sound out the laptop. Also tried plugging in earphones but nothing either

I had a Tosh with a volume dial.

It went to a "POT" and if it was set to low, all you wrote above would be true.

You claim you repair laptops so is the volume dial still in need of re-attaching to the control?

dial is split

I've take the laptop apart to get it out and its broken. The clip which it sits in is snapped in half so not going to be able to fix it that way. So trying to find out what the problem is as the sound is reading on the laptop but no out put

Again, the claim as I see it is you are a tech.

Just like any other potentiometer it could be set at a low level and no matter what Windows is showing the output should be low to off. Why not turn up the pot manually?

There is a 3 buck USB audio replacement if you can't do this work.

no pot
by andantesash / February 18, 2013 4:55 AM PST

Theres no pot dial on it, thats what I looked for when I opened it, theres just a wee plastic part coming up from it and it goes into a chip, you can't turn it either, its locked onto the chip. Is there any other way in the laptop that I can turn the volume up or down - other than the ways I said I've tried

So it's that newer digital pot.

I would replace the broken part, but the chip with the broken wheel clip is on the motherboard and can't find anything on the net for it

A dead model from ebay or craigslist if the parts from Toshiba are too much. I'm guessing here you have not used the phone to ask what FRU is needed and how much.

opened it again

I opened it again this morning to see if there was anything else I could do - I noticed when I force the metallic strips on the dial against the chip on the laptop - the sound plays, but they have to be pushed hard. Is there any way I can just switch to using the laptop software for volume instead of this - like a full disable of the dial chip?

But I thought your were an electronics technician. At this point I'm thinking you are not and would mis-identify a broken pot as a chip. You might not know how, in manufacturing you can paint a potentiometer and well, you are out of your depth. I can't teach basic electronics here but a good tech and jump the pot to full on with a small wire and fine solder work.

have I ever said I was an electronics technician? - think you should go read over things before you post false statements, where have I said I was an electronics technician? I said I have fixed a few laptops in the past - how does that make me an electronics technician?

So how do you suggest I fix this so called pot when there is no where to turn as its broken clean off?

I asked for help from people and you have done nothing but slate me, I wanted help - not for you to say your not this or that!

Don't bother replying as I don't want your help Bob

I read above

You are inside the laptop so you are now a technician.

I'm an electronics engineer so I have to guess what you are by what you are doing. If you are inside, you are a tech. There are all varying levels of techs but to fix this would be trivial for the everyday electronics tech given the story so far.

Sorry to upset you but unless you have the basics down pat with a year or more in some electronics classes you can't be instructed on how to fix this with a small piece of 30ga wire and a little solder work. WHY? Because you don't do this work and I can't see the board from what I am.

So get the cheap USB device before you do any more damage.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
