Ok, did more check. I was wrong. The file UX310UV is really the right one for my UX410UV. I was not enough experimented but after some time, I've got used to the software and I'm now sure, the file is correct
.Thanks...

Re: ASUS ux410u - No power no charge
Hi,
Did voltage injection: really hard to feel any hot spot on this line. I had to go 2.2V and 1.6A.
There, I had a light feeling of hot on CPU. I've put some alcohol and the result is this one:[url]https://youtu.be/j4vOIhsMhRM[/url]. It's not as clear as the EC but the alcohol is really "alive" and as soon as I inject voltage, I see it moving differently.
I tried to put alcohol on caps that are under this area to assert the CPU is not hot only because a component behind is hot. No effect.

Re: ASUS ux410u - No power no charge
Will do that. Not have a lot of time today.
Actually, while looking at the board view, I realized that the highest probability were either pu8801 or a dead cpu (because most/all of the other elements on this line seems to be resistors that have a low failure rate). This line is totally shorted....Leave a comment:

Re: ASUS ux410u - No power no charge
Ok, I have the boardview now and it seems mostly accurate.
The component I was trying to identify is PU8801 which is POWER SW. SN1409049DPUR [URL="https://www.ti.com/lit/an/scba017d/scba017d.pdf?ts=1616878722179"]TI QFN-14[/URL]. The shorted cap is PC8816. It means I have +3VSUS shorted which goes to 62 points on the board.
So, I will do another round of voltage injection on this line. Will see.
@spider: thank you so much for your help today and the ebay seller thanks you too!Re: ASUS ux410uLeave a comment:

Re: Asus UX410U or UX310U
Ok, after looking more closely: my board is similar to the ASUS UX310UV : the general layout is the same (position of CPU, GPU, RAM, jack) but some components seems slightly different. It's better than nothing because some areas are really similar/same but if we can get the real one, that would be even better
Mon2, if you can share your file, it would be great to compare.Last edited by alexvan59; 03-27-2021, 02:57 PM.Leave a comment:

Re: Asus UX410U or UX310U
Hi SMFFlea,
Thank you very much.
The boardview is correct for my board, it will really help.
The repair guide is for UX410UQ. The pictures of the mainboard are different from mine.
Thank you again!Leave a comment:

Re: ASUS ux410u - No power no charge
Seems like another forum members has my boardview (I've seen you replied to him too). Maybe better to wait a little bit. Getting the boardview would really help me....Leave a comment:

Re: ASUS ux410u - Boardview and/or schematic
Hi,
It really looks like this one. Not sure at this size but it seems to match perfectly.
May you share the files?

Re: ASUS ux410u - No power no charge
Yes, it's actually my personal computer (initially, I bought the "dead" one to make sure I have all pieces in case something goes wrong with it). I wanted to avoid opening it. Will continue for now to try to do without it (because I want to learn). If unsuccessfull, I will reopen my personal one

ASUS ux410u - Boardview and/or schematic
Hi,
I was not able to find anything for ASUS UX410U. Does anybody have the schematic and/or the boardview?
I believe the board is similar to ASUS UX310 but not sure (asus said that just the screen is different).
Thanks for any help

Re: ASUS ux410u - No power no charge
Actually, I bought this computer 10€ to a company that wanted to trash it : I didn't test the screen but I strongly believe it's good => so whatever happens to the mainboard, I'm good. I bought it only to learn and to see if I can avoid ewaste.
Thanks for all your tips, it really helps me.
I don't give up until I'm sure it's total game over...

Re: ASUS ux410u - No power no charge
The chip close to the cap has "548 TI 711 ATCK". Didn't find the datasheet yet.
Just to be sure: you believe top pad is ground because we have a huge track or is there any other reasoning?Leave a comment:

Re: ASUS ux410u - No power no charge
[LIST][*] Nice approach. Seems obvious when you say it but I didn't think about it[*] Maybe it was not fully melted. First time it happened to me
. I try to never put too much heat (I've trained my skills on many "dead" boards before). I will look at how to repair them once I'm sure it's worth to try. For the moment, as long as I have a short, it seems a waste of time to fix the chip.[*] can't find the schematic/boardview, seems unavailable [/LIST]- Re: ASUS ux410u - No power no charge
[LIST] - Nice

Re: ASUS ux410u - No power no charge
Ok, will prefer the option of buying preprogrammed if I can.
So, I did 1 and so, removed the chip:
* the three caps around the ec are no more shorted
* one cap behind still totally shorted (see picture)
I removed the remaing cap to see if it could be it. However, the short remain. Since I really don't know which side is + (0 ohms and was 0v), I'm a little bit lost on how to find out what could generate this short.
The bad news is that, while removing the chip, 2 pads are gone =>...

Great, I will do step one. I've contacted the seller too. Will keep this thread updated....Leave a comment:

Re: ASUS ux410u - No power no charge
Hi,
Made the voltage injection this morning. Here are the results:[LIST][*] I had nothing with 1V and not so much amps were consumed (less than 1A). Decided to increase the voltage.[*] No better results with 1.5V.[*] I started to feel some heat with my finger around 2V. Still less than 1A. Decided not go further.[*] Made the videos of alcohol on the EC => injected two times: [url]https://youtu.be/e4m7ZoyPm3Q[/url][*] Came to the conclusion this chip is faulty[/LIST]
The chip ITE IT8995VG-128 is cheap (on AliExpress)....Leave a comment:

Re: ASUS ux410u - No power no charge
Adding a picture to show the shorted caps (in case somebody else get a similar issue in the future).
I have another caps behind the board that seems totally shorted (less than 1ohm on both sides of it)....Leave a comment:

Re: ASUS ux410u - No power no charge
Ok, will try that tomorrow.
Currently, on the + side of these 3 caps, I get ~0.18V and 1 ohm to GND.Leave a comment:

Re: ASUS ux410u - No power no charge
Thanks for the feedback. I knew what super io was but didn't know EC could be the same component.
So, I did some more tests and I believe I'm making progresses. The facts I have right now are:[LIST][*]my main power rail is OK (19.6V)[*]my RT8249C is getting hot. Its pins doesn't get correct voltage. 0.8V on pin 3 and 0v on pin 13. I don't know what would be the expectations on the pin 6&20 but 0.175v doesn't seem normal.[*]My EC SIO is ITE IT8995VG-128. Under "normal" operation(charger plug in), I don't notice any hot...Last edited by alexvan59; 03-26-2021, 07:15 AM.Leave a comment:

Answering to myself at least on one question: EC stands for Embedded Controler.Leave a comment:
