Hi
I have a dead Lenovo S440 here that I need to fix.
Anyone have the schematic for it, COMPAL LA-9761P (VIUV1)?
Cheers

For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

Hi everyone, I replaced this motherboard because it was important to get it working, but it's been with me for a very long time. Now I finally have time to figure out what the problem is,
I've never encountered something like this before;

Good afternoon, colleagues. I have a Lenovo ThinkPad S440 with the 1-3-3-1 beep sequence. I've seen videos about removing the memory because it won't connect properly, but that's not it. I don't know if the issue is with the internal memory, and I was wondering if anyone had a way to disable that memory and test if that's the case.
The power-up sequence is that when you turn it on, it makes those beeps, and the fan and the laptop turn off.
My suspicions are either the CPU or the internal memory. Has anyone had a computer with similar problems?
I'm adding information. I've seen... -
Hi, I have dead t14 gen1 with nm-c931 motherboard.
Laptop doesn't turn on and does not show any sings of life.(battery is completely flat, do I need it for power on??)
When I connect usb c power adapter it draws 0.02A at 20v, I get voltage 20.5V up to 2nd mosfet and nothing out (PQ0006 before current resistor and buck-boost) when I touch gate pin of PQ0006 with tweezers it opens and I get 20.5v on current resistor;
But even with that "trick" I cant get laptop to turn on, that's probably because BQ25700ARSNR is not happy and not making VSYS15 rail.

Good morning everyone, this is my first post and I apologize in advance if there are any mistakes in the post.
I have a Lenovo Legion Slim 5 16IRH8_LOQ with the typical issue of stripes on the screen, but I made the mistake of replacing the screen without physically removing the battery, thinking that just pressing the SW2 button would be enough – it wasn't. The board showed consumption, with LED6301 lit up and PU301 getting very hot. I replaced PU301. Now, the board is not working correctly, but it has no consumption, LED6301 stays on, and I haven't found any other signs of a short...
