After certain amount of time as no activity (connected device off), power LED was off. It is usual behavior as power save ?

for some reason suddenly my connection stopped working. I have tried to reconnect it, but no luck.

Yes, I have found that the lights will go off but when it is connected into a active connection it will work as normal.

Same thing happens to mine. However as soon as I turn on a connected device it lights back up and is connected so I think it's probably a power save mode.

Usually by going to control panel and then display. Could also be a function your power saver mode sometimes reducing the brightness to save power. Jon A

Once it is plugged in, the unit is off (meaning no LED will light up) unless turned on.When in that situation, LED will automatically power on during power failure.If it is not plugged to the wall outlet, it will not do any thing once it is power off.

No, the color of the light don't go to default when power off, always maintain the last setting when we turn it on again.......

Have not had this issue, but would think you maybe right on the money. Your computer may be dropping "vampires" (Items hooked up to your USB that are using power (although very minimal in this case)). As i generally do a daily shut down I have not had this issue.

I have not had this issue, but I do not leave mine plugged in. I would check to see if a power surge took out the unit, or a battery issue

This hasn't happened to me, maybe your power or negative source came loose. Check those connections .

Usually the mouse goes into power save mode. Clicking a button pulls it out of power save. Hope this advice helps.

Doito, went dead, no LED light indicates to me that your batter is nolonger connected, Check to make sure it has not disconnected, make sure it's not bad. Even new batteries are bad out of the box. I experienced this first hand as an electronics tech

Looks like the drive is set up to go to "sleep" after a period of time. That affects a lot of operations, and there's no direct fix for it.

Mine has never done that. battery power lasts a long time. Once and a while the keyboard gets quirky but it comes back when i shut down and boot up again. check for settings. when the keyboard icon is up at the bottom right of you screen it should work. The icon is near the time and wifi icons.

According to the manual it is SUPPOSED to turn itself off ( doesnt say about lights off power down, so I assumed it meant power off the internal amp) after 30 min of inactivity. I have yet to see a sign of that happening even after hours of inactivity. If you are brave you can TRY HK support, but good luck with that. I think i would rather try to communicate with the stray cats I feed about sun spots!!

If the lights remain lit when the computer is off, then the USB port into which this mouse is plugged is still being powered. This is not a fault with the mouse, but results from a setting within Windows or your motherboard. I recommended checking the USB selective suspend options in the advanced section of your selected power plan (even if it's a desktop computer) and the power management settings for the mouse in the device manager.edit: after doing some Googling, I've found some motherboards have what is called 'ErP support/compliance' or 'Deep S5 sleep' modes. If you know how to boot into your BIOS, look for a setting with one of those identifiers, and enable it.

Whenever the unit gains power back it defaults to a power on state, which if memory serves right just turns on the last built in macro of the unit that you were using the last time it got powered off. Hope this helps.

I can't say what that means but mine only goes on when it has been tripped. If there is a sensitivity setting, and I am not sure there is, back it off until the LED shuts off. If there is no setting, there is probably a problem..

Mine does that the LED power meter, though it doesn't appear to light up at all. As the other person responded, is better to have the power meter icon in your system tray in lower right corner, easier to read, more informative, etc.

The power light should go off when the computer is powered off. Since the connector for the device is connected directly to the motherboard, when the motherboard has no power, the device will have no power. Make sure you are not just putting the computer to sleep or in hibernation. Use the full shut down. If you unplug the computer from the power strip or the wall, the light should for certain go off.
