Dell power adapter LA90PM130 dimming pattern on the power cable led indicator!!!

Hello,

I have recently bought a new spare Dell power adapter LA90PM130.

I have noticed a strange behaviour when I started using it. When it is not plugged into the laptop the white led indicator on the power cable goes from bright to dim regularly within a few second in a continuous pattern. When I plug it into the laptop it stays solid.

I am a bit concerned whether it is normal with this model since I had a power adapter with blue led light and it always stayed solid blue.

Can anyone with a similar adapter shed some light, please?
