To display memorized error (Protective operation)
status:
1. Turn power on.
2. Press the CHECK button on the remote controller
continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote
controller. The code "H00" (no abnormality) will be
displayed and signal will be transmitted to the main
unit. The power LED lights up. If no abnormality is
stored in the memory, three beeps sound will be
heard.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit
and code transmitted from the remote controller are
matched, power LED will light up for 30 seconds and
a beep sound (continuously for 4 seconds) will be
heard. If no codes are matched, power LED will light
up for 0.5 seconds and no sound will be heard. 7. The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5
seconds or operating the unit for 30 seconds. 8. The same diagnosis can be repeated by turning
power on again.
To clear memorized error (Protective operation) status after repair:1. Turn power on.
2. Press the AUTO button for 5 seconds (A beep
receiving sound) on the main unit to operate the unit
at Forced Cooling Operation mode.
3. Press the CHECK button on the remote controller for
about 1 second with a pointed object to transmit
signal to main unit. A beep sound is heard from main
unit and the data is cleared.
• Temporary Operation (Depending on breakdown status)
1. Press the AUTO button (A beep receiving sound) on
the main unit to operate the unit. (Remote control will
become possible.)
2. The unit can temporarily be used until repaired

Hp compaq dc 7100 , my problem is that as i start my pc than 4 beep with time interval 0.2 sec with led than after 0.5 sec it start again , remain continously


Are they Long Beeps? Does the RED led light on the front show up?
If there is no RED led light blinking, then the problem is your RAM.
If there IS a RED led Light showing up, then the problem is your Power Supply.

I have a Graco baby monitor, it started making a noise for the last 2 days, could it be a battery problem (even with power connected)? The monitor is about 1.5 years old.


Annoying! happens to us too frequently, but this works. We ended up buying a new one and returning our broken one after owning for three months From Manual:) 5. Turn on the Nursery Unit using the On/Off switch on the side. The green power light should come on. 6. Within a few seconds, the Parent Unit will lock on to the Nursery Unit and the top four (4) green LEDs will shut off. A second later, you will hear a series of beeps and the connection LED should change from red to green. Your monitor is now ready for use. 7. If the top four (4) LEDs do not shut off, power off the Parent Unit and the Nursery Unit and repeat steps 4 and 5 above. 8. If the connection LED on the Parent Unit does not change from red to green and the unit begins to beep, press the channel "ch" button on the Nursery Unit. Within a few seconds, the Parent Unit should lock in on the Nursery Unit and the connection LED should change from red to green. You may hear an audible beep during this process. 9. If the Parent Unit is still unable to lock in on the Nursery Unit (connection LED will be red and the unit will beep), power down both the Parent Unit and the Nursery Unit. Wait for 10 seconds then hold the volume down button on the Parent Unit while pressing the On/Off switch. When the unit powers up, you will hear a single beep and all of the soundlights will illuminate. Release the volume down switch and within 2 seconds you will hear two beeps and all of the Sound Light LEDs will stay lit and the bottom LED will be red. 10. Repeat steps 5

Computer will not start


It all depends how many beeps there were.
From http://h18000.www1.hp.com/products/quickspecs/12253_div/12253_div.HTML
Diagnostic LED Explanation Table Number of 1-second red LED blinks followed by 2-second pause, then repeats:
2-processor thermal protection activated
3-processor not installed
4-power supply failure
5-memory error
6-video error
7-PCA failure (ROM detected failure prior to video)
8-invalid ROM, bootblock recover mode

I have only really come across 4 beeps = order new Power Supply or 5 Beeps = reseat the memory and hope it works

My d530 minitower powers off unexpectedly and red lights starts to blink on System's LED//


Hi Kindly let me know how many times the red light blinks
Condition Code Service Actions Processor thermal protection activated. Power LED blinks red twice, once a second, followed by a two second pause.
  1. Make sure the computer air vents are not blocked and that the cooling fan is running.
  2. Open the hood, press the power button, and see if the processor fan spins. If the fan is not spinning, make sure the fan cable is plugged into the cable header on the system board, and that the fan is properly installed and seated.
  3. If the fan is plugged in and seated properly, but is still not spinning, replace the processor fan.
  4. Reseat the processor heatsink and make sure the fan assembly is attached to the heatsink properly.
Processor is not installed. Power LED blinks red three times, once a second, followed by a two second pause.
NOTE: This condition indicates a missing or improperly installed processor, not a defective one.

Make sure there is a processor in the system. Reseat the processor and verify that it is installed properly. Power failure (power supply is overloaded) Power LED blinks red four times, once a second, followed by a two second pause.
  1. Check the voltage selector, located on the rear of the power supply, is set to the correct voltage (the correct setting depends on the region).
  2. Open the hood and make sure the 4-wire power supply cable is fully connected to the power connector on the system board.
  3. Check if a device is causing the problem by removing all attached devices (such as disk drives and expansion cards), then power on the system. If the system enters POST, power off and replace one device at a time, repeating the procedure until the system power failure reoccurs. Replace the device that caused the failure, then replace each of the other devices and confirm that they are functioning properly.
  4. If you cannot isolate the failure to a specific device in the previous step, replace the power supply. **
  5. Replace the system board.*
Pre-video memory error. Power LED blinks red five times, once a second, followed by a two second pause, and five simultaneous beeps are sounded
  1. Reseat the DIMMs in the memory slots on the system board, then power on the system.
  2. Replace the DIMMs one at a time to isolate the faulty module.
  3. Replace 3rd-party memory with HP memory.
  4. Replace the system board.*
Pre-video graphics error. Power LED blinks red six times, once every second, followed by a two second pause, and six simultaneous beeps are sounded. For systems with a graphic card:

  1. Reseat the graphics card and then power on the system.
  2. Replace the graphics card.
  3. Replace the system board.*


For systems with integrated (on-board) graphics, replace the system board. PCA (system board) failure. ROM detected failure prior to video. Power LED blinks red seven times, once a second, followed by a two second pause, and seven simultaneous beeps are sounded. Replace the system board. Invalid ROM based on bad checksum Power LED blinks red eight times, once a second, followed by a two second pause, and eight simultaneous beeps are sounded.
  1. Reflash the ROM using a ROMPaq diskette.
  2. Replace the system board.*
System does not power on. No beeps or blinks since the system is not functioning. Press and hold the power button for less than four seconds. Perform the following steps depending on whether the hard drive LED turns green.

If the hard drive LED turns green, then:

  1. Make sure the voltage selector (which is located on the back of the power supply) is set to the correct voltage for your region.
  2. Remove the expansion cards one at a time until the 3.3V auxiliary light on the system board turns on. If removing a card turns the light on, replace the card and then see if the system works.
  3. Replace the system board.*


If the hard drive LED does not turn green, then:

  1. Make sure the computer is plugged into a functioning AC power outlet.
  2. Open the hood and make sure the power button is securely fastened in the power harness and that the harness is connected properly to the power connector on the system board. In other words, make sure that the power button is making contact with the power circuit.
  3. Make sure the power supply cables are connected properly to the power connectors on the system board.
  4. Check to see if the 3.3V auxiliary light on the system board is not turned on, replace the power supply. **
  5. Replace the system board.*

one light is for hardrive activity , the other is to show the power is on.. the flashing one is most likely the power light as most computers will tell you when thier ill....the beeping is an error code and should be in some pattern EG: Power LED blinks red twice, once a second, followed by a two second pause. Or something like that. Take note of the pattern and repost it here, then we can give you a specific area to look at.

The following procedure will re-establish the communication link between the Headphones and the Wireless adapter, this is called "pairing". Before you start please make sure both the headphones and the wireless adapter are fully charged and turned off.
Note: The headphones and the wireless adapter come pre-paired from the factory.
1. Press and hold the power button on the headphones. See Figure 1.
headphone.jpg
Figure 1

2. Continue to hold the button down until the LED starts flashing red/blue in an alternating pattern. Release the button when the LED starts flashing red/blue. See Figure 2.
headphone-flash.gif
Figure 2
3. Once the headphones LED is flashing red/blue, press and hold the power button on the wireless adapter. See Figure 3.
receiver.jpg
Figure 3
4. Hold down the button until the LED starts flashing red/blue in an alternating patter. The LED will blink blue, then turn off for a few seconds then blink red/blue. Release the button when the LED starts flashing red/blue. See Figure 4.
receiver-flash.gif
Figure 4
5. Once both the headphones LED and the adapter LED is blinking red/blue, press the volume up button once on the headphones. See Figure 5.
headphone-volumeup.jpg
Figure 5
Once the headphones is paired with the adapter, the LED on the headphones will blink blue once every two seconds. See Figure 6.
headphone-flash2.gif
Figure 6
When the adapter is paired the LED will be solid blue. See Figure 7.
receiversolid.jpg
Figure 7
The adapter may continue to blink red/blue for a few seconds even after the headphones LED starting blinking blue. This is normal; the adapter may take a few additional seconds before the LED turn solid blue.
Once the headphones and the adapter are paired, it is not necessary to pair them again even if the batteries on both units are completely drained.
Additional Note: Repeated pairing will not improve the sound quality or give the headphones and the adapter a cleaner connection.

it all depends on the number of flashes , pause, repeat.
Since the problem did not indicate any beeps her is the following info


Power LED blinks RED 2 times, one every second, followed by a
2-second pause. = Processor Thermal Protection Activated


3 blinks 1 second apart = Processor not installed (not an indicator for a bad processor).

4 blinks 1 second apart .= Power Failure (power supply is overloaded)

Other possibilities are:
5 blinks 1 second apart No memory
6 blinks 1 second apart No graphics
7 blinks 1 second apart System board failure (detected prior to video)
8 blinks 1 second apart Invalid ROM
