Question Asus Zephyrus G14 - Shorted diode? Help!

[mannyloomis]

I redid the thermal paste on my G14 the other day and when i was reconnecting the battery I believe I shorted the diode that charges the battery and reads battery percentage. It currently stays at “100% charged” and only boots on AC power.

This is my first assumption because sparks flew in an area seperate from the laptop’s battery connector. I feel that I didn’t short the battery itself because it still charges through usb-c power delivery (not ideal because it constantly cycles the battery, and i still cant read percentage) and when it initially was broken the battery still had a charge and it worked on battery power.

Do you know of any way I can fix this? I have a soldering iron and a multimeter but i have no clue how to read the blueprint for which diodes to check. I don’t want to buy a new motherboard because replacement is going to be $500+. It’s an Asus Zephyrus G14 G401QM

I have tried:

Disconnecting the battery and holding the power button for sixty seconds.

Calibrating the battery: letting it fully die, sit for six hours, then try to charge.

Uninstalled and reinstalled battery and AC power drivers.

Charging when both AC and power delivery at the same time. (Only works 1 out of a few times.)

Use your phone's camera and take a video with the light one and whether or not you take a video you can use your phone as a "lighted magnifying glass". Look for decolorization, blast marks, where the molten lava reformed, etc, and take a picture of that area. You'll know it when you see it.

Zoom your picture out enough for folks to get context and post it here.

Sounds good, although I’m unsure which one it is. I’m away from the laptop for the holiday but will update the post with it when I get back. Figured I’d get the post up and collect some suggestions in the meantime. Appreciation your reply
