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:

2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not...

Good morning,

Please help me identify an electronic component. The component is in an SOT89-5 package with leads as shown in the photo. It is used on a keyboard board and controls the operation of a specific key row.

The keyboard is a SteelSeries Apex Pro (US). I cannot find a boardview or schematic online. I have already searched AllTransistors, AllDatasheet, etc., and found several candidate types (voltage...

Hello, I am working on a surface go 2 that died due to an input power issue with the charger. I have identified this component labeled 2920M as a possibly bad part. This component starts screaming on thermal imaging as soon as the charger is plugged in. Problem is I cannot for the life of me find a datasheet or anything on this. I can't tell if it's a type of mosfet or what. Anyone have any ideas?
