MS-6712v1.0A KT4V-L

This mobo does not POST

Found two SMT Alu miniature caps amiss near the battery holder.
These should be easy to replace even if I use Pana FM equivalents
(that being so) to test if the patch will fix the problem.

I found the battery completely dead. 0 volts.
Suspect it may be related.
Anyway, I have posted an enquiry on the MSI forums in the
hope some members can ID these cap values.

Which brings me to my next question. I feel an idiot.
How? I have looked at another two SMT Alu miniature caps
on this mobo. The markings are, for example;
10 16G 308 (EC35) and 10 16G 309 (EC46)
The numbers in brackets are the silk screen decals.

However, should I calc. the values as follows;
1. G - 4V working voltage
2. 30 - significant figures (cap value in pF 10^-12) so 30pF
3. 8 and 9 - the exponents (10^8 and 10^9)

Result - mult. 2 by 3
Is this correct?

Just want to check that's all.

Re: MS-6712v1.0A KT4V-L

if they're electrolytics (as you said SMT Alu caps) the're more likely 10uF@16V.
a pic would be helpful.

Attached you'll find a stock pic from MSI

The caps in question can be found;
1. Botton left quadrant
2. Locate battery
3. Both of the caps are to the left and slightly
above the battery

Thanks

Got an answer from MSI Europe via MSI Forums

These are in fact 10uF 16V as you suggested

Thanks

Most likely for audio couplings if negative side is not grounded due to proximity of the AC97 audio chip processor.

Those 10uF/16v caps in the audio signal path won't fail - it's only a line level signal, and there's very little ripple current on them. You can upgrade them to improve the sound quality, for which the Nichicon Muse SW series (85c, subminiature, through-hole) is about the only choice that will physically fit *and* sound great.

Re: MS-6712v1.0A KT4V-L

those 10@16 often are bad on msi boards.
even the ones in the audio path.
