USB power question
On the PC desktop here (Gigabyte MB) the USB power is on at all times the
PC is plugged into the mains. The separate web cam has a couple of LED indicators. I assume this is under BIOS control, but can't find a setting. But then the BIOS uses all sort of acronyms I don't understand. Any easy way of disabling this? So USB power only comes on when I boot the PC? -- *Since light travels faster than sound, some people appear bright until you hear them speak.

Sometimes these tabs go AWOL. |

I seem to recall that on many pcs there are two usbs which cannot be powered
off as they are for keyboard and mouse so if you put it off, one assumes any attempt to bring it out of deep sleep might not work well if you cannot have the power on.

These power measurements are done with DIPM enabled. ’ Spinup current is measured from the time of power-on to the time that the drive spindle reaches operating speed. ’ Read/Write current is measured with the heads on track, based on three 64 sector read or write operations every 100 ms. ’ The drive supports two idle modes: Active Idle mode and Low Power Idle mode. ¬ Power Dissipation 5TB, 4TB & 3TB models +5V input average (25Β° C) Ό € Spinup (max) 1.2A (6W) Ό € Write average 2.10W Ό € Read average 1.90W Ό € Idle, low power mode 0.85W Ό € Standby/sleep 0.18W ΄ Standby power is measured at steady state (after 200ms from transition) /q from: https://superuser.com/questions/1171...ve-connected-t |

I dont any since I have changed over to those magnetic things, mainly to keep the lightning port on the 6S blocked so it doesnt get fluff and dirt in it in your pocket. I used to use a little rubber plug but those arent available anymore for some reason and are fiddly to remove and replace every time you charge the phone and easy to lose. The magnetic thing stays in the port forever and the other magnet snaps on when you want to charge the phone. It comes with all the 3 connectors so I have the micro usb in the headset now and charge it the same way, using the phone charger, but I did use the PC USB previously. Same with the cordless keyboard. |

No news and irrelevant to that comment to Brian. just for enabling or disabling it and which connector it comes out on when you dont want it on the back panel. What? Most of the USB ports are on the motherboard itself, and are on the back of the case when the motherboard is mounted in the case. It is more convenient to have at leas some USB ports on the front of the case and most motherboards do have stakes on the motherboard that the computer end of the front USB port cable(s) can be plugged into. |

Define relative :-) My 9 year old Gigabyte MB supports what it calls, "On/Off Charge Technology", where it "allows you to charge your iPhone, iPad and iPod Touch regardless of whether your PC is on, in standby mode or even off". |

Not really sure the age of the original Asus. It certainly started off with XP, before going to Win7. Couldn't get it to work with Win10 hence changing to an all singing and dancing Gigabyte. And now I've got on top of the various things needed to get it to do what the old MB did, performs rather well. Still find the BIOS settings anything but intuitive, though. With the handbook not much help. -- *I got a job at a bakery because I kneaded dough.* Dave Plowman London SW To e-mail, change noise into sound. |
