He did include the mb code,it does look more like a model number though , its 330S_ARR_V06 , its silkscreened between the CPU and RAM slot. There`s no schematic available at the moment .

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.
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.

This is a site for free help,you`ll get help if you post the schematic or not. With the schematic it may be easier to track down the problem.First of all you need to correctly ID the motherboard part number,it should be silkscreened in white between the RAM slot and CPU .Post the part number or a picture as an attachment.
Thank you for replying, I see the Part Number now.

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.
Its simple. the burnt part is a capacitor. Remove it.Clean the pads and rebuild the track. Check that 2R2 resistor. It could be bad as well. Do check resistance on the caps pads. You may leave it without the cap for test purpose.
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” or specialty tester
This part of the laptop forum is for schematic requests only. The main laptop forum is here - https://www.badcaps.net/forum/forumdisplay.php?f=23 please start a new thread there for help with the repair,and please attach images directly as an attachment.
The part number isn`t P/N: 431204237090 ,its above that,itll say something similar to 330S_KBL ,tell us the full name .
Hi I'm trying to figure out whats the matter with my laptop Lenovo 330S-15ARR-81FB. I need the schematics to figure out if the bios is "OK" and which component are damage. the laptop start, fan i running, led light is white and charger is working, keyboard light is working perfectly, Caps look light and num lock light doesn't work, no video. I press FN + R and the charger light start blinking 3 times and keep blinking in a endless loop.
Please I need the schematics and if you can give any help I would appreciate it.
Hello Mindtain, could you send me the schematic archive? I need it to make a project with the laptop computer, my idea is to make a desktop and I can't go on this withou the schematic
