Help with Part ID

[Pesti]

This fell off a Toshiba satellite motherboard. Does anyone know what this is ?
and where I might get a new one. Thank you, Pesti

Re: Help with Part ID

Hi - Bigger photo might help. Presume there are no other markings on it.

A picture of the base might also help.

Which model TS was it off and was there a designation on the board.
Perhaps a pic of the area of the board it came off would help.

Re: Help with Part ID

Judging by the tiny pic, it looks like an enclosed inductor/coil of some kind..

Re: Help with Part ID

Either an inductor or capacitor.

Post a picture of the area and the exact model of the laptop.

Re: Help with Part ID

yea I finally got my camera working,,,so here's the photo of the area,
(like my little red arrow? lol}

this is a Toshiba L305-S5933 #PSLB8U-027025 It came to me Dead as a doornail.I spent about 3 hrs trying to figure out what the problem was. I noticed heat from the area around the power jack, and wished for the hundredth time that I had some type of thermal image device....

Anyway any help would be greatly appreciated,

Pesti

Re: Help with Part ID

Can you still be able to read the continuity between the two legs of this inductor? If you can, you can try solder it back on the PCB. This inductor is used for the switching power supply section.
As far as the DC input jack is concerned, you should remove the old solder and resolder real well at both top and bottom of the PCB, very common problem in laptop due to of mechanical support for the jack.

Re: Help with Part ID

That's one of the inductors for either the system DC-DC or battery DC-DC. I can see the MOSFETs next to it.

The schematic for the L305 is floating around somewhere on the Internet, should be possible to find with some quick Googling. That'll show you exactly where to start looking for power.

Re: Help with Part ID

Thank you both, do either of you know if I can pick one up from ebay?
Also..
I tried a while back to register at PC SCHEMATICS But the registrations closed for now :.( I'll keep looking..

Re: Help with Part ID

But did you try Ohming it out to see if it does not have open winding yet? A close up pictures will help.

Re: Help with Part ID

Found the schematic, I'm gonna ohm that right now....

Re: Help with Part ID

My camera sucks, well actually I'm an idiot when it comes to things I'm not interested in
and this POS camera (That's "piece of ****" lol) is one of them. I managed to get a decent
close up of the board this am but now I can't seem to get the settings to the same place.
It's an old Sony cyber shot, from like before Win xp, and it doesn't have an instruction manual it has an instruction "Novel" The settings arn't logical and I don't have the patience right now to figure it out again. Anyway, Here's the deal, The inductor looks like the black plastic base is chipped away, (I'm not sure if someone tweaked on this laptop before I got it, but I can tell you that half the screws were missing out of the base) and I can see part of the winding on one side if i put the probes on the 2 connector legs i get a reading...so...

Re: Help with Part ID

It should have very low resistance if it's OK.

Just solder it back in and see if that works. If it doesn't, you can find the value on the schematic to go buy a new one.

Re: Help with Part ID

I second that.
