Is the Lenovo 135W charger causing Framework 12 battery issues?

Continuing the discussion from [Solved] - [Framework 12] Battery exhausively/deep discharged/drained in BIOS/UEFI (no LED/power light). How to power?:

So yeah, I solved the issue with Framework’s support (shoutout to them! They are really good!). Indeed they sent me a new mainboard and I could replace it. (Really worst thing was [connecting the wifi card antennas/cables

Still the correlation to the battery drain (at 0%) is striking to me, IMHO. For the record: The laptop also started charging at 0%. While the battery could have gone empty if it really was charged up until 80% as previously thought, I really doubt it.
Well… that stays a mystery I guess – unless Framework analyzes the mainboard that gets shipped back to them.


Above was a draft reply, I forgot to send. The sad thing: actually it just happened again.
Why this happened, I have no idea, this time. Yeah the device was low on battery again. But iirc this time I plugged it in soonish and while being at that charger, it died.

Also already tried the reset button and powering the laptop without any battery. Seems another (?) mainboard problem?
Though iirc I had used the saame charger (original Lenovo 135W) that I had been using before. I have no idea why this happens.

Also people: be careful with these wifi cables, it’s annoying as hell.

Again no led has any light at all. Neither the outer nor the inner one.

Okay hmm I begin to strongly suspect the USB C power supply.

It is a 135W Lenovo “brick” and it looks very sturdy, has all kinds of signs and Lenovo is also a well-known manufacturer. So why?

It’s one of these: 135W USB-C Lenovo ThinkPad power adapter (just arrived with T16)

Why?

  • I had the original framework issue, see old thread.
  • then I had an issue with a Lenovo IdeaPad (IdeaPad 1 15IGL7 Laptop - Type 82V7) where I also attached that charger (iirc also because it was running low or already at 0%, but maybe I tried a different lower powered charger first, maybe even the framework 60w one)
    This one thankfully needed no repair, but the usual hardware reset button you find on Lenovo devices on the bottom. The one you need a paper clip or SIM tool for. (but not the novo button)
  • then the Framework 12 again while being attached to that charger(!), aka this thread
  • just after I noticed that, I tried plugging in my phone (Fairphone 4 FP4), which did not detect any charging activity(!). I even plugged that into the framework 12 60w charger afterwards and it also did not charge, so I was already going nuts thinking two devices could break? At the same time? Thankfully, for the phone just rebooting seems to have solved it.
    But yet alone this should indicate something is wrong with that charger, is not it?

Anyway this is all very strange and I have no less wqhats going on or what could be wrong – about that charger, I guess.

It seems possible that the Lenovo charger is causing some problems. Many devices have some self-protective behavior in their hardware and/or software layers that will disable ports at the moment an external electrical issue appears [out-of-spec voltage, overcurrent, shorting, etc.]. This protective behavior may persist until the electrical controller resets. To me, that sounds like what you’ve done by rebooting your phone and pressing the hardware reset button on your Lenovo machine.

There may be some hard-to-see damage to the charger’s USB-C connector, but that’s a total guess. If I were you, I wouldn’t use that charger anymore.

Thanks yeah, its there some way to diagnose this/issues?

Also, as for the framework, it seems to have no such reset button? Is there any way to fix it? If the theory is correct, it also “disabled” all usb-c ports.

There are some threads throughout the FW13 and FW16 topics that you should be able to apply to the FW12 to perform an EC reset. It MIGHT be as simple as booting into your BIOS, hitting the “disconnect battery” choice, then rebooting your laptop, but it might be a bit more involved.

Okay so already impossible as it does not boot at all. :upside_down_face:

Question: This probably doesn’t need to be asked, but have you tried charging via each port?

Also, here’s a mainboard reset guide specifically for the FW12. I don’t know the source of your current issue, so it might be the case that this isn’t helpful and you get to step 7 only to find that the status indicator it mentions doesn’t blink. If one port doesn’t have a blinking indicator there, I’d try each other port.

Yeah thanks, tried both, does not work.

If the charger is causing malfunctions on multiple devices, it’s not safe to continue use
