Problems
Unable to use the
keyboard
Possible causes
The white LED indicator
at top of the keyboard
does not light up when
the keyboard is turned
on
Possible solutions
1. Check if the battery is inserted
correctly.
Battery "+" and "-" ends must
follow those indicated on the
battery compartment label.
2. Check the battery level.
• If the keyboard uses a
rechargeable battery,
ensure that the battery
is fully charged.
• If the battery is exhausted,
replace it with a new one.
3. Turn the keyboard off,
and then turn on again.
Check if the battery-status
light is flashing amber,
indicating that the battery
power is low. If the battery
is fully depleted, the battery-
status light will not turn on.
4. Ensure that the Dell Univeral
USB receiver is directly
connected to your computer.
Avoid using the port replicators,
USB hubs, and so on.
5. Change the USB port.
Insert the Dell Univeral USB
receiver into another USB
port on your computer.
