Blinking WiFi LED Light - Turn it OFF

#1 Post by Rhino » Wed Sep 21, 2005 2:51 am

Second only to the fan problem comes the (green) LED blinking. This is by the Intel WiFi controller. The LED is on the LED strip located underneath the LCD. This thing blinks enough to put you in an epileptic siezure (not really).

My question is, how can I turn this LED OFF?! I know I can open the Thinkpad up and then do some splicing/cutting/unplugging, but is there another way?

I can't WAIT to get this blinking to stop!

I don't notice it. If you don't use wireless just disable it from within Network Connection in the Control Panel.

You could try not looking at it. Seriously. I use wireless a lot and I just don't notice the light. It seems to me (I'll check later) that if I am wired and Access Connections turns off the radio, then the light doesn't operate.

Later note: If you use Access Connections and set it to turn off the wireless radio when using wired, then the indicator turns off with it. When I am using wireless, I want it there so it all works perfectly for me.

> My question is, how can I turn this LED OFF?!

Fn+F5 the select the Click To Change Status button (on the "Wireless Radio" tab page), until it the "Status" shows "Off".

Cheers,

Wirelss light on 2668 Q2U can't be turned off if you are over wireless network ....

it only blinks when there is an wireless network activity.

in IBM a/b/g cards it flashes so rapidly that you feel see light is on and some thing inside light is flashing (bascally light doesn't goes completly off and comes back)

with intel it goes of and then comes back. first I thought some malfunction but I realized that it's not coz I was still connected.

you can turn it off only when you are not using wireless card.

I would suggest to use one of those round stick-on screw covers that IBM uses over the screws on the ThinkPad. Stick cover over lighted icon. If yours is like my T42, there is already one of those round covers about 3/4" to the left, so it really wouldn't stand out very much.

AFAIK there is no way to have it off and use your wireless card simultaineously - short of disconnecting the LED.

I have a little sheet of those black sticky screw hole covers, if you send me a private box msg with your address, I will put a few in an envelope and send them to you, no charge! I put electrical tape over my blinking annoying clock on the vcr so I sympathize.

My light blinks with traffic (that is irregularly) and I use the IBM card. I would not expect a card change like this to change the indicator behaviour (just like changing the Hard Drive does not change the hard drive indicator behaviour). ... JD Hurst

Windows 7 (may work for XP, VIsta....just look for the key. Its not OS specific, its device specific)

Click start, Run, type: regedit
Go to: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0011

On right, scroll down to LED mode
Double click LED Mode to change value

Mine had value: 3, continual blinking while on
Value 2, 1 and 0 appear to have same result; stable on unless transmitting, off when radio off.

All I know is, it stopped blinking ALL THE TIME.

This is the solution if you want to enable/disable or turn on blink LED on network activity, (only works on Intel cards apparently).

it works on a windows 10 T400 with a intel Wifi link 5100AGN. in my case, the LED was always on if the Wifi was connected, by i wanted to blink on network activity, so i created the DWORD value "LedMode" with the value 1, now it blinks only on network traffic just like i wanted.

my registry path is: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\0002

the trick is to make sure you are on the right Wifi card folder just like they explain in the link, in my case, was the folder 0002.
