The title pretty much sums it up, however here are the details.
I have managed to get a hold of my laptop's schematics due to them being
leaked.I am currently working with someone over at Bios-Mods to modify the
firmware ("unlocking it").Interestingly, this laptop (which I had already
updated it's firmware), has no WiFi whitelist, and I had bought brand-new,
about a month after it came out.
The EC controller, an ITE IT8586E-LQFP, is connected via the LCP bus, and the
touchpad, internal keyboard, and the NCT7718W thermal sensor are all connected
to it, according to the schematics.I forget whether I have the same exact chip
(though I believe it to be so) on my laptop, as 99% of the details match my
laptop.
The schematics refer to 2 SPI chips, an 8MB W25Q64FVSSIQ_SO8 on UC3 as the main
SPI chip, and an 4MB W25Q32FVSSIQ_SO8 on UC6 as backup.I have only one SPI
chip, an 8MB W25Q64FVS1011532 on UC3, with the UC6 solder point existing, so I
could theoretically solder a backup SPI chip.A TPM chip, the Z32H320TC, also
sits on the LCP bus, with a direct connection to the chipset, unlike the
touchpad, internal keyboard and the thermal sensor, according to the
schematics.I forget whether I have this TPM chip, but once again, I believe
that it is so.
The IdeaPad 300-15's motherboard is codenamed "Paris".
It also (optionally) comes with an AMD dGPU, without direct connection to any
graphical output.My specific model only has no dGPU.
Can anyone help me with my research? I'm still not very experienced with the
actual work regarding electronics, most of my experience is with researching
them.If there is any more information required from the schematics, I'll gladly
share them, and if anyone wants the schematics, I can send them over.
