Noted, will create a thread and figure out proper ways of showing information.

Re: schematic for lenovo 330s-15arr

I appreciate your confidence lol, so indeed that blown component is a capactitor and the 2r2s being resistors, I couldn’t find them online as the only repair place in town is asking for what the part is and some are saying to find what blew it up.

Does the topside and bottom of the motherboard interact? I put a picture of the spot where it is burn and maybe some of the pathways(?) go to the Dualband wireless ac. Sorry for my ignorance.


Edit: also can I get away with computer safe DMM or invest in a “fluke”...

Re: schematic for lenovo 330s-15arr

Thank you for replying, I see the Part Number now.

P/N: 431204237090

I have pictures I've compared with to the schematic (didn't have to purchase to see) and the area that is affected is exactly the same silkscreened numbers and shape, so all looks good for that.

I can post pictures of the areas and schematic comparison.

Re: schematic for lenovo 330s-15arr

Edit: I'll buy the schematics and post them here if someone is willing to help, if that's how this site works, It looks identical to my MB from what my untrained eye can see.

Re: schematic for lenovo 330s-15arr

Hello, not sure if this will be seen in such an old post but I cant post a thread.

I have a lenovo IP330s-15ikb(HSB J MV-6 94V-0 E89382), not sure if CPU(IKB/ARR) changes what the schematics are but i found some on a pay site, (I read i'm not allowed to post pay sites, but you can zoom into the pics pretty good.) I am brand new to this stuff so I am also wondering if the schematic can help isolate what blew a component on my MB. ..+a few other questions.
