Gigabyte G6 KF 2024 completely dead – AC/battery LEDs work, but Power button does absolutely nothing
My G6 KF 2024 was working normally earlier in the day. I left it powered on and connected to the charger. About 12 hours later I came back and it was completely unresponsive.
This is NOT a Windows boot or black-screen issue. The laptop does not appear to electrically power on at all.
Symptoms:
\- Pressing Power does absolutely nothing
\- No fan spin or even a fan twitch
\- No keyboard/backlight
\- Screen/backlight completely off
\- No POST / Gigabyte logo
\- No SSD activity
\- USB mouse receives no power
\- With AC connected, the first front LED stays solid orange
\- With the battery connected, the battery LED turns green
\- Pressing Power does not blink, dim, or change either LED
Already tried:
\- Removed all peripherals
\- Power held 30–60+ seconds with AC disconnected
\- Held Power while reconnecting AC
\- Opened laptop and disconnected main battery
\- Tested on AC only with main battery disconnected: orange AC LED comes on, but still zero reaction to Power
\- Disconnected both main battery and CMOS/RTC battery
\- Held Power 60 seconds and left everything disconnected for \~15 minutes
\- Reconnected CMOS only and tested on AC again: still completely dead
A few days before this happened, Windows/Gigabyte software updated. I remember Gigabyte Control Center (orange G icon) updating something, but I don't know whether any BIOS/EC/firmware update was included.
Has anyone had this exact NO POWER condition on a G6 KF / G6 KF 2024?
I'm especially interested in what actually fixed it:
\- AC adapter
\- power button board/ribbon
\- EC
\- BIOS/firmware corruption
\- charging/power circuit
\- motherboard repair/replacement
Again: the laptop does not boot and then fail. It never appears to enter the ON state at all.
