Wireless LED Indicator doesn't turn off in Aiplane Mode.
Is it normal behavior?
In addition, CMOS battery had just 0.28V.
Is it ok for 3 years laptop?
Is it just bad battery quality or something wrong with the laptop?

Do airplane mode and wireless function work properly?

Do airplane mode and wireless function work properly?

Yes, all wireless functions work properly.
P.S. One guy told me his GP75 also has the same problem.
However, I don't think it's a normal laptop behavior.
