Bottom of T430 motherboard

#1 Post by skx » Sat Mar 02, 2019 8:50 am

I need to flash the bios chips of my T430 to install coreboot/neuter intel ME. For X220/X230 it is very easy as the bios chips are located under the palmrest. For the T420 and T430 it is sadly located at the bottom/downside of the T430 motherboard. Is there a way to remove the bottom case without fully disassembling the motherboard? I want to avoid removing heatsink and repasting the CPU.

No no no no no no no no.

Did I mention that wouldn't work?

Ok exaggerating aside, literally the motherboard the top top pieces of the shell are screwed to the bottom. *Pun intended* your really kinda screwed here.

yes, but can we detach the motherboard from the bottom case without actually removing the heatsink... that was the question. we know the motherboard is attached to the bottom case with screws, I just want to avoid removing heatsink for a 5min bios flashing operation, we do manage to remove screws :mrgreen:

You probably could, I've done it on other Thinkpads in the past, not specifically a T430. Just make sure to support the heatsink to ensure you don't put unnecessary stress on the CPU or heatpipe.

Having just motherboard-swapped my T430 the sad truth is that yes, you have to COMPLETELY dissasemble the laptop. (I am removing whitelist for wifi, but need the T430 working)

The infuriating thing? if you are good with tools, you can remove a section of (creat an opening in) the Mag main chassis, which then only requires removal of the KB and palmrest, Nothing more and this COULD have been done at the factory, but hey, we are not supposed to know how to flash the BIOS are we?!?!?!

I measured out and marked my spare Mag-Chassis as I intend to do this mod when I swap back my original mobo into my T430. I'll grab a phot later and post it so you can see the location and amount of material. It's not much, but enough to get the SOIC in and hooked up.

Thank you for your clarification. I will as such plan a full saturday soon to properly disassemble and to look into rebuilding the chassis a bit to facilitate future disassemblies :) I confirm, it is a pain in the *** compared to the x series to flash our bios chips hehe

It honestly took me less than 30 minutes to dissasemble my T430 and about the same to rebuild with the interim motherboard.

The main problem being that unless an access is cut in the Mag-Alloy main chassis, a full strip is required. A small acess opening will stop that requirement and simply mean removing the KB and Palmrest in order to flash the bios. Less than 15 minutes work overall.

I have the photo I needed to take, so once transfered, I will post it up so you have the positioning and size of aperture.

I'm interested to see this photo.

@Erbenzähler
Did you make a spelling mistake when you entered your username Erbenzähler?
Are you a counter of heirs?
Or did you mean to use the name: Erbsenzähler, which is a bean counter?
(just nitpicking here :) )

Yea I messaged admin about it. I joined this forum using my cell phone because my computer was bricked at the time. I made a typo. Trust me, as a nit-picker, this makes me cringe.

You can start nitpicking now, I just made you a bean counter! :mrgreen:

At least on the T430 the SPI flash signals are routed to the connector headers J14 and J27 which can be accessed from the top of the mainboard but I guess both are hidden under the structure frame.
See the second picture on this page of the bottom area with J14 and parts of J27.
