Assuming you mean Alpha and not Adobe (or even amber), I don't see where it makes a difference. When in standby mode, "
IF" a LED is lit, I still have only seen 1 LED. But that certainly does not mean there are no boards that light multiple LEDs when simply shutdown (put in one of several stand-by modes). I'm just not aware of any, nor do I see a purpose for more than one lit LED when in stand-by.
It should be noted there is no industry standard for LED lights on motherboards. None are required. If any are present, there is no standard for the color. And regardless the color, there is no industry standard for their function. When powered up, a lit LED can mean anything - depending on what the motherboard maker chooses. They could be solely for aesthetics. Or they could simply indicate power is present. Or, if more than one, they could represent some code that is supposed to be useful in troubleshooting.
All I am saying is when in standby, a lit LED usually just indicates there is still voltage present on the board.
I meant addressable the ones that can output multiple colours on a strip or fan.
Right. The thing about hibernate mode and notebooks is the notebook is supposed to boot back to exactly where it was when it went to sleep (or you closed the lid) - with all your programs running and open windows opened as they were - even if the battery runs down completely. So the notebook is not just booting to the Windows desktop, but if you had a Word document or Excel spreadsheet running, and your browser was open with several tabs open, they are all supposed to be restored too. That's why notebooks, even under normal conditions, often take longer to come out of hibernate mode - especially if your network/Internet connection is not the fastest. But the point is, you "shouldn't" lose any data (most recent Word doc edits, for example) when coming out of hibernate mode.
The function does work perfectly
most of the time. But as Mussels noted, sometimes it doesn't.
I have found one of the common reasons for hibernate failures is low free disk space.
Note for PCs, there is the "hybrid" sleep mode. This is different from hibernate in that the +5Vsb standby voltages also keeps the data in your RAM alive for even faster wake speeds. DDR4 really takes advantage of this.
But if the computer loses power for any reason when in hybrid sleep mode, no problem because the hiberfil.sys file (used by hibernate) was also created when it went to sleep and that's the file that restores all your open programs, open windows and documents.
