Thinkpads Forum

Hey All,

When I press FN+F5 I get a message stating:

"Unable to change power state of 802.11 wireless radio. Update the driver for the wireless adapter."

After clicking on OK, it goes to the Bluetooth and WWAN options only. I know I have seen this before, but this was due to me using the non Lenovo drivers. I thought it might be a new driver bug as this is the most recent driver 10.5.1 (I believe), so I rolled back to the previous version by first uninstalling first: still no go.

Another issue I have is that when I used to press caps lock or scroll lock it would show a message in the lower right-hand corner about the specific key being pressed. It does not do this anymore.
I uninstalling and reinstalling the FN on screen application and it still did not work.

Any help with these two issues would be great.

Thank you!

Sounds like you need to reinstall the Hotkey utility driver.

I had this problem and it was complicated to fix. i'd do an image backup first or at least restore point.

do you use access connections? if so I'd remove that also.

remove wireless driver
remove hotkey software
remove acpi power mgt

install acpi power mgt (reboot when necessary on all reinstalls)
install hotkey software
install wireless driver test with windows after a reboot
install access connections.

i called tech support and this is what they told me for the same error on a t43.. its frustrating because as far as i can tell they never mention it in any of the individual installs or readme (but i could have missed it).

i have one t42 that i can't fix it with, and for that if you go into the network connections you can just disable and enable the wireless as a workaround, hope it helps

Thank you very much both of you. I will try these suggestions and let you know what happens.

Thank you
