My Ps4 fell down except for the warning from the Ps4 that the power cable should not be pulled out while the Ps4 is on, there were no noticeable problems.
Then she's going, right?
If you can still play your games on PS4 without any problems, then everything should be fine. But take care not that something really breaks in the end…
The warning is only an indication so that successes are not lost.
Which the PS4 only saves when you turn it off, then it turns off.
