Power connection status LED blacked out after safety removal

After purchasing the WD NEW My Passport 1TB (hdd), to operate the external hard drive safely for a long time.
While waiting for 30 seconds after safety removal, the newly purchased WD LED does not blink slowly and does not wait.
…so I doubt that the power supply is unstable.
In the end, it is judged that the power saving mode is not working.
I asked the seller, but the LED behavior of the new WD seems to have changed.
So, do you have a new manual?
Seller… There is no new manual…

eventually refunding

My new WD LED movement is…
When the power is connected after safety is removed,
The LED is blinking slowly and the system is waiting.
It’s the same model, but why are the LED movements different?
