Hello, I have the i7-4600U variant of Lifebook T904. I have a few questions about it:
Can I replace the WWAN card in this laptop with a MSATA SSD?
Occasionally there is a constant buzzing sound both on speakers and headphones. On Linux I've managed to fix it by reducing the PCM value of the soundcard below 50. Is there a way to fix this on Windows as well?
The white labels on my keyboard have started to yellow a bit which makes the backlit keyboard much less effective. I've tried to clean it with wet wipes and cologne however that didn't change much. What can effectively clean the yellowing on the keys without damaging the plastic?
Thank you
