Troubleshooting and Maintenance 55
Performance
Symptom Possible solution
Computer displays a
processor speed that is
lower than expected. This happens when the processor is automatically running in a
lower power state, because the applications running do not
require the maximum processing power.
Software programs and
files take longer than
expected to open or
respond. If you created multiple user accounts on your computer, ensure
other users are not logged in. If there are multiple users logged
in simultaneously, system resources must be shared among
them.
For information about other tasks, see “Maintenance tasks to
improve performance” on page 61.

The device may have too many connections. Either wait until
the device is less busy, or set the other devices so they are not
discoverable. For information on how to turn off discoverability,
refer to the device instructions.
Ensure other devices that use radio frequencies (for example,
microwave ovens, cordless phones, and 802.11 wireless
networks) are not creating interference. Try moving the device
that is not working farther away from other devices.
