I have an Acer E15 E5 laptop two usb3 ports and one usb2, and when I
plug a flashdrive into one of the USB3 (but not the other ports) it lights up even when the computer is off, and when it's not plugged in. What's with that? I've never seen this mentioned in a spec. Is it about waking up the laptop? (Will this be true on my desktop too?) I've heard of wake-up on LAN and iirc wake-up on phone (???), but not wake-up on USB. |

What a good idea. But I never heard about it before. :-) RwP |

What's with that? Its done like that so you can have wake on keyboard or mouse. I've never seen this mentioned in a spec. Its common with the best desktop motherboard manuals. Is it about waking up the laptop? Yep, when you have a keyboard or mouse plugged into that port. (Will this be true on my desktop too?) Yep. I've heard of wake-up on LAN and iirc wake-up on phone (???), but not wake-up on USB. Its normally called wake on mouse or keyboard. Obviously with usb keyboards and mice. |

That would have attracted my attention even more, using words I know like mouse and keyboard. (I still have trouble with high tech like USB, so I skim over them. ) But this is good. I always use and external mouse and keyboard, so I'll plug one of them into that jack. Haha, the only reason I plugged it in was because I was trying to see if I could plug in two things side by side. Flashdrives are narrow but this laptop has no 3.5mm jacks, so I need** a USB to 3.5 adapter and they have an amazing amount of circuity in them which makes them either 0.79 or 0.81 inches, except for the first one below which puts the electronics at the 3.5mm end, not the USB end. narrow one https://www.amazon.com/gp/product/B0...T49GGF3B&psc=1 wider one https://www.amazon.com/gp/product/B0...TGSOMSJG&psc=1 This one and another one push the fact that they are narrower than some others, but they're still wider than one above that puts the electronics at the other end! **Wait!! I fixed the desktop so I don't need the laptop while I'm home. I'll talk about that in another thread. https://www.amazon.com/gp/product/B0...T49GGF3B&psc=1 |

I've heard of wake-up on LAN and iirc wake-up on phone (???), but not wake-up on USB. It does say it in the owner's manual. I read it but didn't understand what it meant: "USB port with power-off charging" On page 57 it says "Some USB 3.0 ports support charging devices when the computer is in Hibernate or turned off.", but I hadn't read that. And there's a headset/speaker jack too. I forgot I'd read that and the little hole is hardly noticeable. |

That problem is trivially fixed by using a tiny usb extension cord or a usb hub. **Wait!! I fixed the desktop so I don't need the laptop while I'm home.
