Asus X54C (YA-4A 1 94V-0 K53C Mainboard Rev 2.1) - Identifying Burned Component for Replacement

Question

Motherboard YA-4A 1 94V-0 K53C mainboard rev 2.1 It's a symbol of a burned bone to be able to replace it. I believe it has the same symbol as the...

It is to be explained in a random way.

boro1234567 · Answer

Both keys are identical. To check the latter, I suppose that the driver also for replacement. Further defects can be excluded.

Replace this bone with an inscription identical to the other one or vice versa, or does it matter?

boro1234567 · Answer

Are you kidding me? The laminate is marked with pin 1 mosfeta.

wentyl215 · Answer

I do not see anything here, I asked a question and I wanted an answer, but not ... always around. EDIT: Regarding the thickened line on the laminate, it means that it is opposite to the other one.

wentyl215 · Answer

Thanks, next question ... I have some plates for parts, I have to look for bones with identical signs, or maybe there is something to pay special attention to (some one symbol or something)

boro1234567 · Answer

It's best to look for the original transistors. If you do not find it can be a replacement with the most similar parameters.

Can it be about such a sign? NIKOS P20036VG GN27K2510

boro1234567 · Answer

There is no transistor. Verify the designation.

I have one, I can check myself only, I do not know where to look for these signs:

Here you can find pdf: https://www.google.pl/ Compare the data, choose something.

wentyl215 · Answer

I was thinking about the link to the page you probably have. But ok, I will look.

boro1234567 · Answer

https://www.google.pl/ Here you will find everything if it does not exist, it does not exist.

wentyl215 · Answer

I know that, I will probably find answers to my questions there too, and this forum is to send to the gugel and make people look for on their own.

boro1234567 · Answer

Do you think that where do I look for the application? A little initiative, minimum effort on your part.

wentyl215 · Answer

Minimum? I presented all my models, some were very hard to read

boro1234567 · Answer

Did you download at least pdf to compare parameters?

wentyl215 · Answer

I have something like:

http://elportal.pl/pdf/k01/33_06.pdf

and

http://www.elektronik.edu.pl/strnaucz/strona_ss/Katalog/indexx.htm

I will review this in a moment ...

EDIT:
Nothing here, I need to look for a directory specifically for field effect transistors (MOSFET)

Added after 1 [hour] 37 [minutes]:

I have something like this here:

P1203BV or the one to be replaced:

p2003Bvg is it suitable for a replacement?

or FDS6690AS:

boro1234567 · Answer

I did not let you search for directories only applications.
Is it so hard to stick the transistor designation into a browser and add a pdf?
Again, following the pathology:
http://www.cheertech.com.tw/Niko-sem/Data%20sheet%5CP2003BVG.pdf
http://datasheetz.com/data/Discrete%20Semicon...OSFETs%20-%20Single/FDS6690AS-datasheetz.html
http://www.unikc.com.cn/UploadFile/products/201578170504-UNIKCP1203BVREV1.0.pdf
You can make a comparison with the comparison?
If you had any doubts, I would use FDS6690AS, not forgetting what I wrote about the driver.

wentyl215 · Answer

I found a very similar ME4410A, replaced it, gave it power and got 0.41 for "stanby", but when it tried to switch it on, it drops to zero and the diodes go out.

I do not know whether to exchange the second Mosfet ... after cleaning the plate with alcohol everything looked OK, as if the openly damaged singed everything around.

boro1234567 · Answer

I wrote you something but how hard you are in my earnest.

wentyl215 · Answer

I did not understand ... did you mean the bones of the bios? It looks fine, I wrote, editing the post, that after cleaning everything looked ok.

boro1234567 · Answer

You had to measure / check / replace the second key and driver.

wentyl215 · Answer

I exchanged the other, but I do not know where the driver you are writing about.

lisek · Answer

Driver (driver) is this system , which has? pins connected to Gate (gate) of transistors

ME4410A is a typical field N-ch used early in laptops in DC-DC chips. stanby, power supply of the processor or RAM
Link_ datasheet ME4410A_Matsuki

For example, the Stby system

If you have "seared" after inserting it, look for other damaged R elements, maybe C in its surroundings or the mentioned driver.

wentyl215 · Answer

No, I meant that the initial picture shows damage to the transistor and probably other parts, but after cleaning and the bone of the bios and other parts looked like new.

After all, I replaced both transistors, and now I need to find the driver.

boro1234567 · Answer

. Items are measured / replacing not watching. transistors That's how you find him. W / g me it is him. Confirm.

lisek · Answer

There is no SM for this CD, so we can only use similar solutions from Asus. If we talk about - BQ24740 charger is in layout we have field inputs, channel type P (first, eg TPC8107) and second N-ch (stands behind measuring resistor (R010)) * check the BQ voltage on pin.10 (VREF./ 3.3V) and compare ... * something like for example here - Stby + LDO + 5V (for Hall and KBC sensor (IT8572E)) we have there RT8206L and its out. we have half the same type of N-ch. * bit differently than in RT8206A / B see role pin.20 ** datasheet in app. *** L - say it is 8206A Link __________________ Power supply Bios comes with + 3VM_SPI> created with + 3VSUS (after Stby) ps Probably we talk about Chip Richtek Power Supply Controller RT8206L-M
