My laptop got stuck, so I tried hard reseting it but I left the power supply in, so it shut down but the keyboard back light stayed on. I tried restarting it again, but it won't.
That doesn't work and it's not a removable battery.Press and hold the power button on the laptop for 10 seconds. It should be off. Press the power button to turn it back on. If needed, remove the battery and try with it plugged into the wall.
Yeah, the only light that's on is the keyboard backlight. It's ASUS TUF Gaming FX505DY BQ002TSo, the only thing you can see is the keyboard light? Nothing else? No light activity for the HD if you have it? What about eth port? Do you have one of those? What make/model laptop?
