FW 13 11gen Water Damage

[Gustje04]

Hi everyone,

I have a Framework 13 (11th Gen), and a few days ago I unfortunately caused some water damage. The water got in from underneath the laptop through the bottom vents.

After that, the device was completely dead — no lights, no response. It turned out to be a short circuit.

I managed to fix that fairly quickly (about 2 hours — my first time doing board-level repair!).

Now the boot diagnostic LEDs show the following pattern:

GGGGGGGG RR GG

So the red LEDs are:

• 9 Fan detected and spins up
  I can actually see the fan spin briefly, then stop.
• 10 CPU reached S0 state
  I couldn’t find much information about this. Could this mean there’s still a short or fault in the CPU power supply? Is the CPU just done?

Any ideas on what my next steps should look like?

Thanks in advance!

Try disconnecting the battery, a short circuit on the mainboard may damage the battery management system (BMS)

[Gustje04]

Hi, no damage to the BMS is no issue. Like i sad i fixed the shortcircut now when i connect the board to the Lab Power supply it dose not draw too much current.

In the mean time i read out the EC debug messages

I am not so shure what to make out of this but i keep digging

[Charlie_6]

I guess I were wrong about the battery. The problem could still be the mainboard

[Gustje04]

You know they say RTFM TI BQZ50 Datasheet on page 35 under 9.2.2.2.4 . I think that explains all my battery issues.

[2disbetter]

I would suggest that you contact customer support. 9 and 10 being red means that those things were not detected. The CPU being able to reach S0 is the suspend state of modern standby. It in conjunction with the fan control not working speak to a power issue / damage.

[Gustje04]

Thanks for your suggestion. I wanted to give a bit more context about what happened. While debugging the short circuit on my FW13 (11th Gen mainboard), I traced the issue back to the 5V buck converter. During troubleshooting, I noticed that PLZ101 was getting quite hot, so I removed it.

I’m not entirely sure what PLZ101 is — it seems to be an inductor (“L”), but I accidentally lost it (it fell out of my tweezers; it’s an 0805 SMD). Removing it made the short disappear, but it looks like PLZ101 mainly bridges the 17V rail to the input side of the 5V buck converter. After carefully injecting voltage to the 5V buck converter, I identified the real shorted capacitor, but I had forgotten to bridge PLZ101.

After making the post, I realized I had wasted a lot of time troubleshooting, and then remembered that the removed PLZ101 could be the issue.

As a quick fix, I replaced PLZ101 with an SMD fuse I had on hand in the same package, acting as a temporary bridge. The laptop is now working, and I’m writing this from my repaired FW13.

I am now coordinating with a local repair shop (whose owner I know) to get access to the official schematic, so I can replace the two components with the correct parts.
