Reference number: CH000232
When booting computer I receive
several beeps.
Issue:When booting computer I receive several beeps.
Cause:
This can be caused by one following
possibilities:
- Keyboard has a stuck key.
- Computer has a password.
- System Chassis alarm.
- Computer does not pass POST.
Solution:Keyboard has a stuck
key
A stuck key or a
keyboard that has failed can cause the computer
to beep abnormally.
- Turn off the computer and temporarily disconnect the computer
keyboard and turn on the computer. If the beeping does not occur
when the computer keyboard is disconnected it is likely that a
key is stuck or that the keyboard is bad. Slapping the back of a
keyboard to dislodge any dust, dirt, or hair may help ensure there
are no stuck keys on the keyboard.
Computer has a
password
Some computers have the capability
of having a BIOS keyboard password. This password will sometimes
cause the computer to beep and the keyboard not to work. To
determine if this is the case look at the keyboard
LEDs (Num Lock /
Caps Lock / Scroll Lock) if these are flashing continuously the
computer has a password.
System Chassis
alarm
A beeping or buzzing tone can also
be caused by the system chassis alarm also known as the intruder
alarm when the system case is removed. Verify that the beeping or
buzzing noise does not also occur when the computer is off. If this
is the case attempt to remove and cover of the case and then put the
case back on.
Computer does not
pass POST
The more likely possibility of abnormal
beeping is when the computer does not pass the
POST (Power On Self
Test). When the computer fails this test it will sound a 'Beep Code'
indicating what caused it to not pass the POST.
- See document CH000607 for
additional steps in troubleshooting issues related to the POST.
- If you're getting a continuous beep or a beep that does not stop
and no display see document CH000995
for additional steps in troubleshooting this issue.
