Why did the laptop not turn on, and then turn on after two weeks of inactivity?

Question

laptops

The laptop stopped turning on, did not react in any way to pressing the power button. PSU is good, no battery. After 2 weeks they tried to turn it on again and it just turned on as usual.
I want to know, if this happens, then for what possible reason? I'm not rummaging through the hardware, I just assume there must be some characteristic cause of this kind of malfunction.

Answer 1

The fixes have been fixed, I'm afraid it's impossible to draw another conclusion

Answer 2

The encoders in the power supply are dry.

Answer 3

Offtopic. Sorry, I can't resist. Once 2 weeks, then the quarantine survived.
I had this because of the wire

Answer 4

I watched something similar on an old laptop, there was a little connector in the laptop itself where the wire powered by the power supply was plugged in, after moving it a little everything started up normally

Answer 5

There may be a problem with the power button.
If it repeats, try pressing harder and in different places.
As an option.

Answer 6

Maybe static. While working for those. support, with such a call every couple of weeks. The laptop is not HP for an hour? The advice was, if it already happened: Press the power button 2 times for 15 seconds, with the power supply and battery turned off.
