What is the locked led for?

The LOCKED LED light just tells you what digital device is ready for use. If your PC is on and running and hooked up via USB, then the USB LOCKED light will be off, meaning that your PC is on and ready to be used. If you have your HDTV turned on and hooked up via OPTICAL, then when you toggle over to OPTICAL you will see that the LED light is off. If you have a third device like an Apple TV hooked up via COAX but that device is turned off, then when you switch over to COAX, you will see that the LED light is ON. The LOCKED LED light is red.

It has a hold feature on it, that keeps you from accidentally changing any of the settings. If that's not what you need to know, describe what you mean by "lock" and I'll try again to answer your question.

I'm pretty sure it's a small NiCad battery, the type used on OLD computer motherboards to keep time/date info while the computer was off. I have no idea why this was included with the light.

Are any of the three LED in the upper right corner of the keyboard lit? Sometimes when it boots one of the locks defaults to on and you have to shut it off. It might be SysRq which you disable holding the function key.

It has a blue LED that's pretty well blocked when both ports are occupied. I haven't opened it up so I'm not sure about protection. The housing states 2.1A max per port.

There is no LED connected via caps lock and num lock keys to indicate connectivity

i'm not exactly sure... but I think the lock switch disables all functions to avoid pocket unintended turn ons.

Hello Garcia. Thank you for your question. Unfortunately you cannot disable the Led indicator. The only way is to cover it with something (like the piece of parer or cloth).

It is a non user serviceable sealed assembly. The LEDs should last 10's of thousands of hours. However if one goes out then 3 will because there are 4 x parallel series of 3 LEDs. If one series of LEDs goes out the odds are the problem is the driver circuit not the LED itself, so you would either accept that it became a ~ 15W light that's a little dimmer or buy a new one.

Led I don't know but it works with UV light...I don't know the difference between the two

Either the batteries are installed improperly or the light is defective. Does the lock work?

The Caps Lock and Num Lock keys appear in an LED window at the top middle of the keyboard. While it shows as white/clear light in the window, it is very easy to know if the Caps Lock key is engaged as an uppercase A appears. The number 1 appears to show that the Num Lockis engaged. In my review with Logitech, my suggestion is that it may be helpful if the LED appeared as blue, red, amber or some other color.

You may be using the wrong flasher. LEDs require a solid state flasher because they have very low current.

it does not have indicator lights, i think because it helps save the batter live. you can download many different programs to have the status of the num-lock, caps lock displayed on the desktop. hear is one example: http://support.microsoft.com/kb/894037

the only thing I have been able to use it for is testing. As faw as I can figure out the thing of by-passing the bad socket does not work at all. Light are lights whether LED or not

Yep, it is a replacement LED should the on board LED go out. I disassembled the unit by mistake (thought I had to insert the battery, da!) I'm not one for reading directions! I hope this helps.......

You have a turn key to lock and un-lock the door. the battery is for the light and the keypad itself.
