The Num Lock key is turned on. Press the Num Lock key. The Num Lock light must be off if
you want to use the arrow keys on the keypad. You can also
disable or enable the Num Lock key in Computer Setup at
Advanced > Device Options.
There is no sound or sound volume is too low.
Cause Solution
System volume may be set low or muted. 1. Check the Computer Setup settings to make sure the
internal system speaker is not muted (this setting does
not affect the external speakers).
2. Make sure the external speakers are properly
connected and powered on and that the speakers'
volume control is set correctly.
3. Use the system volume control available in the
operating system to make sure the speakers are not
muted or to increase the volume.
Cannot remove computer cover or access panel.
Cause Solution
Smart Cover Lock, featured on some computers, is locked. Unlock the Smart Cover Lock using Computer Setup.
In case of forgotten password, power loss, or computer
malfunction, you must manually disable the Smart Cover
lock . A key to unlock the Smart Cover Lock is not available
from HP. Keys are typically available from a hardware store.
Poor performance.
Cause Solution
Processor is too hot. 1. Make sure airflow to the computer is not blocked. Leave
a 10.2-cm (4-inch) clearance on all vented sides of the
computer and above the monitor to permit the required
airflow.
2. Make sure fans are connected and working properly
(some fans only operate when needed).
3. Make sure the processor heat sink is installed properly.
Hard drive is full. Transfer data from the hard drive to create more space on
the hard drive.
Low on memory. Add more memory.
Hard drive fragmented. Defragment hard drive.
