@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
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
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.
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.
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.
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.
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.
Does Framework replace the out-of-warranty mainboards that had the overheating/plastic-melting ZB08P03 chips? These MOSFETs were on mainbards of the batches 5 and 6, iirc. Some reports mention or suggest a high CPU load while charging the battery- If that is not the regular use of the working mainboards and they carry the same fault, the defect may manifest much later after a period of such high-load situations.
And to satisfy our curiosity: has the root cause ever been found?
