How to check weather computer is set to the correct voltage.

When the STANDBY indicator

flashes

Immediately unplug the power cord

and check the following items.

• If your unit have a voltage selector,

is the voltage selector set to the

correct voltage?

Check the voltage for your region,

then make sure the voltage selector

is set correctly.

• Are the + and - speaker cords shortcircuited?

• Are you using the supplied

speakers?

• Is anything blocking the ventilation

holes on the rear of the unit?

After checking the above items and

fixing any problems, plug in the power

cord again and turn on the unit. If the

STANDBY indicator still flashes, or if

the cause of the problem cannot be

found even after checking all the

above items, consult your dealer.

Hi,

9 beeps means that the input voltage to the PC's power supply is incorrect, have you changed the switch at the back of the PC from 110 to 240v or vice versa. If the PC was not bought in the UK then it may be set to 110v in which case the voltage selector at the back of the PC needs to be changed to 240v. If there is no voltage selector would recommend changing the power supply.

If by changing the selector to the correct voltage it still beeps 9 times you are looking at a new power supply unit which you can buy from HP at a high cost or buy a used one from:

Hope this helps!!!

Hi,when Element does not heat up correctly

1. Test for power to determine that the unit is receiving the correct voltages.
2. If the power voltages are correct and you have standard surface burner elements:
1. Test Surface Burner.
2. Test the Receptacle.
3. Test the Burner Switch.
3. If the power voltages are correct and you have solid-disc elements:
1. Test the solid-disc element.
2. Test the Burner Switch.
4. If the power voltages are correct and you have radiant heating elements:
1. Test the radiant heating element.
2. Test the Burner Switch.


1. Make sure the controls are set properly that the oven selector switch is set correctly and that the temperature switch is set to the desired temperature. Where applicable, make sure the oven timer is set to manual.

2. Make sure the oven door is slightly ajar as per your owner's manual.

3. If nothing else on the Range, Oven or Cooktop is working then:
1. Check the circuit breaker or fuse
2. Test for power

4. Test the broiler element.

5. Check the oven thermostat.

6. Check selector switch.

7. Check oven cycling relay.


REMEMBER YOU ARE WORKING WITH 220 VOLTS - USE EXTREME CAUTION .

Please if no experience, please contact a skillful personnel for assistance.

STEP: Ensure Correct Power Button Is Used and Is Not Sticking or Broken. If the power button remains depressed during the power-on attempt, the computer immediately powers off, mimicking a "no power" symptom. Ensure the button is not being held down too long or binding against the bezel or chassis. If necessary, remove the front cover to press the button directly.
2. or else...STEP: Check the Power Button LED on the Front of the Computer (on Blinking yellow)
Initial state of LED at power up.
Indicates system has power, but the POWER_GOOD signal is not yet active.
If the hard drive LED is off, it is probable that the power supply needs to be replaced.
If the hard drive LED is on, it is probable that an onboard regulator or VRM has failed. Look at the diagnostic LEDs for further information. or lese..
3. STEP: Restart the Computer Using the Power Button.Press and hold the power button down until the computer powers off. This should not require more than 10 - 15 seconds.Press the power button to turn on the computer.
4. STEP: Verify the Power Supply Voltage Selector Is Correct for the Region. Verify the setting for the power supply:
*Unplug the power cable from the back of the system. *Press and hold the power button for at least 5 seconds to discharge remaining power.*Inspect the voltage selector setting on the back of the machine (Figure 1). Ensure that the voltage select is set in the correct position for the region the in which the system is operating: For Europe and Asia, the voltage setting should be 230V.In North America, Mexico, parts of Central and South America, and parts of the Caribbean, the voltage setting should be 115V.*Plug the power cord back into the back of the system.*Turn on the power.
STEP: Try a Different Known-Good Wall Outlet.
STEP: Remove All External Devices. Turn the system off.
Unplug everything from the front and back of the system except for the power cord or AC adapter, including: keyboard mouse monitor speakers printers scanners USB devices handheld PDAs external Zip or CD-R drives joysticks/game pads, etc
Attempt to turn the system on.
STEP: Check the Power Button LED on the Front of the Computer

Blinking Amber/yellow: Initial state of LED at power up.
Indicates system has power, but the POWER_GOOD signal is not yet active.
If the hard drive LED is off, it is probable that the power supply needs to be replaced.
If the hard drive LED is on, it is probable that an onboard regulator or VRM has failed.
If all the lead is off, then have the mother board replaced

sounds like the cpu is dead, if your fan was full of dust theres a high chance it wasnt working properly for a while which would of caused the cpu to fry from lack of proper cooling and also the dust in the vents would have prevented heat from escapeing so its highly probable that the cpu is dead try replaceing it, i cannot gaurentee that anything else internally got fried from the heat tho, i had a similar problem a week ago

IF A&B are yellow and C&D are green it indicates a memory error.

If A&B are yellow and C&D are off then it indicates that the computer is in sleep or reduced power mode.

What was your symptoms before you replaced the video card? Sometimes if the power supply is weak or bad or you have a bad motherboard then you get no video output. Check your cpacitors on your mobo for leaking or swelling. Let us know what you find out.
