I'm sure none of those 15 years of experience has been dealing with Windows 10.  UEFI over BIOS now, get with the times.

Do you have the issue? or are uou going to be the same people that are giving false resolution "its a hardware problem"?  Numerous people in this thread and other posts have already replaced their battery and power supply AND IT DIDN'T RESOLVE THEIR PROBLEM. So suggesting to boot without a power supply is really not doing anything new.

You would think if you had 15 years experience of doing something, you would have learned to read the thread first and see what others have done already 😒

More than 15 years fixing computers do give an idea of what i'm talking about.

Notice that what i said only applies if the computer is turned off. The computer turning itself off by disconnecting the charger can be a windows problem, i admit. However, I asked if the computer would not turn on if the charger was disconnected.. if this is the case, windows has nothing to do with it. This is a fact.

I don't need to be a chemist or physicist to know that the water that comes from my tap is in liquid form. The same way i don't need to see your computer to know windows has nothing to do with it (if the problem is what i've stated).

Think of it this way, if your laptop had an hard drive (where windows is installed) and you removed it, try to turn the laptop on and it would still behave the same way, would you still blame windows? If your answer is no, then why do you blame it when it's still not even loaded in memory?

You haven't done enough reaearch or experienced the problem, so please don't comment like you actually know what you're talking about.

I've had the issue and was able resolve it via software rollback.  IT IS NOT A HARDWARE ISSUE.

If you can't turn the computer on and go to the bios then the problem isn't windows, period. When the computer is turned off, window's isn´t even loaded.
