Help needed with motherboard repair - capacitor problem

Hi to all.
I have Acer tablet c300 and it’s out of warranty and there's a problem with the motherboard now. One of the capacitors (red arrow on the picture) on the motherboard accidentally fell off and lost while I was trying to fix the loose power jack. Do you have any idea about what type of capacitor it is (capacitance, working voltage, etc.)? It is of the same size as the capacitor beside it (yellow arrow). The dimension of the capacitor is approximately 2 mm by 0.8 mm.


The picture is in the address below:

 

Are you sure it's a capacitor and not a resistor? I hate to say it, but your best bet would be to try to contact Acer and see if they take pity on you. I've had luck with Panasonic helping me find a replacement switch for my volume on my car stereo when it broke.

Anyway, you may also just be able to run without it, or bridge it with a touch of solder, and hopefully end up with nothing worse than some spotty sound over the speakers or whatnot.

I'd also consider vacuuming thoroughly in the area where you were working on the power jack, and then sifting through the bag when you've done so. That may be your best/only way to get the correct part.

If it's a capacitor, it's in the 0.1 picofarad range, in a 0603 package size is what it's called. If it's a resistor, it could be anywhere from the mOhm to the kOhm range, which make huge differences of course (also a 0603 package).

 

Can't open that picture.

Pitabred: not 0.1 pF. Not a chance in hell. Somwhere between 100nF and 10pF, but not 0.1 pF.

If it's indeed a ceramic cap like Paitabred said, there's a very decent chance the notebook will work just fine when powered on.

 

Er, oops. They do go to the 1 pF range or so, but I was reading the tolerance I believe Just a quick google around to figure that stuff out. I don't work with the things, I just know a bit about electronics in general and figured I'd throw him a bone.

 

Thank you all for the replies.

Although the component is not labeled It is most likely a capacitor because it has brownish grey colour as other capacitors do (which have labels c19, c20, etc.) while resistors have black colour (labeled as r19, r20, etc.) on the board.

I tried to turn on the laptop but it does not boot up. When I pull the switch, Couple of the indicator LEDs blink once and pretty much nothing happens except that the cpu fan turns on and battery is charged.

I will contact Acer about it and maybe I can find out what capacitance it is.

 

Can you read the label on the IC next to it? It's connected to pin 17 or so, shoul d be easy enough to figure it out.
What's the component on top? Looks damaged. Sure the solder joints are ok?

 

The label on the IC in which the capacitor was connected says:

1SL
6218CV
L0340HBBL
Any idea what it is?

The part at the top is the power jack, I applied glue to it to fix it, that's why it appear kinda of rough. Other parts and solder joints look fine to me.

 

It's ISL.

Linky.

Unfortunately, classified datasheet. If you feel like it, mail and see if you can get it. I might be able to help you further after that.

 

Well I wouldnt recomend trying to solder anything on a pc unless you are VERY good at soldering. Other then that I cant help you sorry.

 

he's already soldered on it, so the damage is done Didja try vacuuming the work area, swmelon? I really think that'd be a good idea, seeing if you can just get the old part back.
