I'm looking for the CORRECT schematic and component layout for a Lenovo 320S-14IKB motherboard. I have found one which is SUPPOSED to be correct, but the component designations look wrong. Does anyone have a link please or recommend a safe site for download? There's one called realschematic.com and another laptop-schematics.com> First one is cheaper but is it good? Thanks!

What is the board number? NM-xxxx? LA-xxxx?
If it's LA-E541P check here:

I quite agree that it should be free!! Unfortunately, alisaler does not have 320S-14IKB schematics 🙁

Oh yes!! That is the one! Thank you - I should have spotted that myself. I have a blown PL504 inductor on sheet 41, so possibly a shorted 10uF cap or the DC-DC chip itself. Cap more likely, I guess.
Thanks for your help.

Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:
The schematic... -
Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this... -
Laptop name Acer Aspire E5-574G. Processor = i7-6500u. GPU = NVIDIA GEFORCE 940M. Motherboard Model = DA0ZRWMB6G0
This laptop was not powering on at all so I started investigating. The blue light would come on for a second, and then disappear. Fan would sometimes turn on for a second and then shut off immediately, and at other times would not turn on at all.
To start with, about 3 months ago I had no clue about soldering, motherboard schematics, board view, and then I stumbled about this forum and other stuff online. I have never done any of those before. But to ask... -
Hi guys, I'm working on a MSI Ventus RTX 4080 16G. The GPU has 12v, 5v, however what I assume is the 1.8v rail has 1.1v and what I assume to be PEX is 0v. As you may have guessed already there is no Vmem and no Vcore.
I have looked around in related forum posts for a schematic so Much appreciated if anyone can share a Broadview schematic.
Thanks. -
Please help, i need schematic diagram for Dell inspiron 3537 board LA-9982P rev 3.0 (A02). Specific for A02.
I have a one beep with no display problem. Did reprogrammed the bios but no luck. i tried to troubleshoot using rev 3.0 (A08) version schematic and boardview but there's components/rails in the schematic that is none in my actual board, this is why I'm having problem checking every power rail needed if ok. attached is the photo of my actual board.
I'm not sure if A02 and A08 is really different schematic version from each other, but I have to try....
