I'm using a Dell Inspiron 620S desktop with windows 7.
I have a very strange problem. We recently installed the software for a wireless Bluetooth adapter to be used with our Bose Soundlink. Shortly afterwards, we noticed that the Dell USB wired keyboard, if left unused for an hour or so, would not respond. After rebooting it worked fine.
Realizing that the only change to the system recently was the Bluetooth software installation, I did a system restore to just before it was installed. The keyboard worked fine, even if sitting for extended periods, and I never had to reboot.
I then went ahead and installed the wireless Bluetooth adapter software again, and the problem with the keyboard has returned.
What in the world could be contained in that software that makes the keyboard refuse to respond when it hasn't been used for an hour or so?
I appreciate any help you can give me with this weird problem.
You can try this:
Sorry for the long delay in answering your response. Unfortunately this didn't work. After sitting for awhile inactive, the keyboard still refuses to respond without rebooting the machine. Thanks for trying.
Turn off the USB Power save feature on all ports. Change BIOS to S1 sleep not S3 sleep. Enable Legacy mode in bios and enable WAKE FROM SLEEP ON USB in BIOS.
