Just saw this on another forum. On some caps it looks like a plastic coating is peeling/falling apart.
Does anyone knows what's up with those caps?

Looks like some kind of insect damage, The aluminum is not touched, it is just the coating that is being eaten.Comment

Hi folks,
This HP Pavilion Aero 13-be1021AU came to me for a repair. And it seems to have a weird BIOS chip. (Pic attached)
I asked my CH341A to read it and doesn't even know what to do with this. We are both very confused.
BIOS - XMC 25RU128CH10 (1.8v)
What the heck is this? I looked all over the MB. This is the only bios.
When I asked the NeoProgrammer to detect it, it just pops up an empty screen, and asked me to enter the bios number. And when I did, it doesn't do anything. NeoProgrammer showed me just this SPI ID: 204418. Don't know what... -
2022 was crazy busy around here....I really didn't get to play with many of my toys.....
Lets start out 2023 a little better on that front, beginning with a bad Quadro FX5800....
...but this is what I was after, the outer shell...
The casing surrounding the heatsinks is plastic....however the backplate feels like magnesium or some alloy....not completely sure, but it's not plastic.
This will make more sense as the project develops....especially what weird build it's going in...but HAPPY 2023!!

This started a few days ago and does this about every 8 hours
After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup
The battery backup is about 3 or 4 years old
Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start -
So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:
1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.
2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not... -
