Hi Sarah,
That’s very odd as we would absolutely want to get this board back for review. Can you please DM me with your order number please? Thanks!

I received an email afterwards saying I’ll get sent a return label as well as a new mainboard, I haven’t received an order number or a confirmation for a new mainboard yet however.
Gen 11, the first November batch, running linux mint at the time, with I think bios 5.03?
Just adding mine to the pile, I was watching the tempreture senses when it died and the main chips were in the balmy mid 60s, which meant the fan was on low but by the time I realised the chasis on the left was now too hot to touch, it crashed.
I had an external dac pluged in the bottom left side along with charging the framework through the top left, so it seems like the extra heat from the current was just too much.
No error codes to speak of, I think because the left led also got roasted

@Matt_Hartley I’m the pushy Kiwi that used our national post’s forwarding address and then had to get Kevin Crawford to authorise a “one-time courtesy” shipment for a fan replacement, so also probably one of the reasons there is now a specific ‘no forwarders’ note on the shipping page.
So definitly not under warranty, though if the engineering team want another subject to dissect I’m happy to talk to support and send it back

Hi @Liam_Beaumont,
Yep, that was me. Please contact Support regardless and let them know I sent you and to be escalated to Tier 3. While you are correct this is likely CID, we’ll see what options are available. I sincerely appreciate your honesty.

Just contacted Support probably 20 minutes ago but just had the same issue happen to me. I was in batch 5 or 6 cant remember. Was charging on the upper left side under medium/high duty use
Thanks for sharing this with us. Contacting support for resolution is the correct step to getting this sorted.

Batch 4 DIY 11th gen here (1165-G7), found this thread when I was researching tb docks and just popped mine open to check. There’s no sign of melting/overheating. Do keep us posted though.
I also charge on the upper left side, have a mainboard from batch 5, and have a melted plastic cover. I noticed it because I was looking to reset the mainboard after my laptop died, but wasn’t seeing any lights on the left hand side.
Now that I see the damage, I’m guessing it might be the cause of the laptop/left USBs not working.
Is it still worth sending this in for analysis?
Edit: edited “because the USBs aren’t working” to correctly order cause and effect. Also, I contacted support ^-^
Both of the USB ports on that side don’t work?
If so, the overheating of that chip could be the reason those ports stopped working.
You have a 2nd Gen Framework? Regardless of the generation, I’d suggest contacting support.

The overheated component does look a lot like a mosfet and it is a bit far away from the cpu to part of the vrm so if that is part of the power routing to the ports on that side it would explain the usb ports not working. That does however not mean it would be the initial cause of the problem, mosfets tend to die from issues down/upstream a lot more than just by themselves.
Very curious what support finds out. Unfortunately normal users can’t get the actual schematic and board-view, cause then you could exactly tell what component that was and what it was connected to.
I believe it’s one of these EMZB08P03 MOSFETs.
The number on the chips can be read here [IN TICKET] Piece of mainboard partially melted - #6 by Yunlee, and the logo is clear in other pictures.

Hi guys, firing up an older thread but, we’ve got 1 of 24 of our framework laptops doing this same thing. Mosfets show up to 302F/150C while plugged into a 20v 45w PD power supply. If I can get the computer to boot without flashing codes, it boots with zero USB port functionality and no errors in the device manager. Tried installing latest bios release and it then failed to boot. Anyone having luck getting these boards replaced being out of warranty?

Mosfets can get pretty hot, but if you’re seeing parts of the mainboard melting, you should absolutely contact support so that they can look over the hardware and help you with a possible replacement.

Yesterday my left rear port stopped charging, opening up show the same melted spot. Reported to support today.
Mine is a batch 10. Order date april 1 2022. DIY i7-1165G7

And a question to all who had such a board. Did you charge mainly through the left rear port? The melting locations point to specific MOSFETs. Those for the right ports are on the backside and have no plastic cover to indicate too much heat, but they could slowly cook the memory in slot 0.
Now there are 18Edit: 12 of the BnnP03ZB08P03 type (‘Z’ is manufacturer? Third line is a time/batch marker) on the board that may fail later on.
Frameworkers: Does Framework still exchange boards with this issue, even when they are out of warranty?`
The manufacturer, Excelliance MOS, is represented by the stylized “M” logo.

Follow the link for datasheet
Users have posted quite a few pictures, and every one shows overheating in only one mosfet, the one located right next to the LED. There is no reason to believe that all of those chips are inherently bad or destined to fail. Rather, it looks like there was an issue that overloaded just the one chip in that particular spot.

Ah, thanks! I had thought the B08/B09/B12/B20/… were all the same only with different ratings, and read one datasheet only.
I had to correct their number, it’s only twelve B08P03, six per side (of laptop, as well as of board).
I beg to differ. Here is a mainboard for sale where also the second chip I marked in the pic had been too hot. The seller has likely drawn a high current (to conclude from 64GB RAM included in the offer), possibly while charging the battery, through a left side USB port. When it failed, he tried the other left port, until it overheated, too. Is that correct, @Reese_Borel?
In this thread, where the port is mentioned, is is the left rear port, hence always the same chip. For the other ports and chips, “absence of evidence is not evidence of absence”.
The backside B08P03 chips were found too hot, too, pointing to a right-hand port.
@Usernames: Can you confirm/debunk that this happened when the power went through a right side port?
FW seeks the root cause upstream, the diagnosis went from FW to mainboard manufacturer to chip manufacturer.
To me the most likely the root cause is a (sub)batch of bad chips. Those chips would have come on the same reel, placed on the same board together, and die successively from too high currents, causing a variety of different symptoms: Black Screen Issue, intermittent contact with USB storage, thunderbolt not working, etc.
@TheTwistgibber: Has the real cause been found?
FYI he no longer works at Framework.
