Re: Asus Zenbook ux31a component identification
I have forgot to do this but better late then never.
I got the backlight to work after replacing the inductor. The fault was a defective LVDS connector which shorted the backlight net to ground. So all worked after this. Thanks again Atsio for the help!

Re: Asus Zenbook ux31a component identification
Atsio could you help me out here, i am going to order the components now but I got really confused (again!) here as the burnt inductor L4510 that was seated before looks very different to the one you proposed, also i wonder if the current/voltage rating is to low on thatone considered this is the AC_Bat line which to my head should be rated higher than around 150mA/5Vdc?
Could a 120Ohm/100Mhz ferrite bead which i understand also is a inductor type component like this have been used? [url]http://au.element14.com/taiyo-yuden/bkp1608hs121-t/ferrite-bead-0-035ohm-2-7a-0603/dp/1786262[/url]...

Can you send me the photos of the Asus Zenbook motherboard you took in large resolution (the largest you got). I collect them.

Re: Asus Zenbook ux31a component identification
Ok, that sounds like good news then! I think i order the inductor and cap and do a temporary fix to the lvds connector and see what happens from there. I get back later with an update how things ended up!
Big thanks for all the help atsio, i would never have figured this out on my own! I gotta learn how to read those schematics.

Re: Asus Zenbook ux31a component identification
Have checked continuity between C965H and USB, dont mind the placement of the numbers they are only used to navigate from =) Came up with this:
Continuity C965H pin 3 and usb 2
Continuity C965H pin 6 and usb 3
Continuity C965H pin 2 and usb 4
Also measured 5V at USB Pin1 with power on. Are this to any help?...

Re: Asus Zenbook ux31a component identification
Yes, i checked continuity from pin 8-11 to the no 19v pad and they are connected so i think you spotted the right component here. There seems to be no short as of now.
No i didnt measure 12v anywhere, my point was maybe it is strange that 12v voltage was missing. But maybe its nothing strange at all with that as i am the newbie here =)
I have also looked for "C965H" with no luck. The only thing that makes me believe the schematic are right is that the model name "UX31A2 Rev 2.0" matches...

Re: Asus Zenbook ux31a component identification
Good evening.
Thats some really good info there, thanks for that Atsio! I have removed the cap and the broken inductor as you said and checked some voltage. Seems something is wrong about those components, is also 12V missing? I dont know if that would be present at those places. The 6 pin smd reads "C965H" and the 8 pin "IC" reads "UA DY" but not really sure about thatone its hard to see.
When i order a new L4510, how do i know which one to buy? Inductance value seems to...

Asus Zenbook ux31a component identification
Hello all!
I am new here but have followed this forum for some time now. This is my first post and i was wondering if someone could help me identify the components i marked out! This is all about a Asus Zenbook ux31a bought defective. It starts up without any screen. I also attach the schematic file to this mainboard. Unfortunately i do not have the "board view" file. Is it possible to identify those marked components without the boardview? I sure cant =)
I also see that pin 10+11 on the LVDS connector have been shorted, dont know how that happened. It has...
