All Lights blinking with beeping...

Turn off the printer and leave it off for several
minutes; then turn on the printer again.

No Display, so does it seem like the computer booted up and is running except that the Display is black? Do you hear fans running, disk drive spinning, blinking lights or beeps?

I'm going to assume that in your case since you mentioned a red light that it is not booting up all the way. Therefore your problem is probably with the memory, the video card or some other motherboard issue.

Remove the Power Cord, Remove the Battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Replace the fan or your computer will run hot and keep turning off.

Or are you saying this is what happens when you power on the computer? if so: When you press the power button do you hear fansrunning, hard drive spinning, lights on the computer, hear any beeps or lightsconstantly blinking, hear the DvD/CD drive click and the light on the drawer ofthe DvD/CD turn on for a second or two? If so the laptop is trying toboot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Solutions List:

• Replace or reinstall the BJ Cartridge ( Print Head ) - BJC-85
• The BJC-85 may require repair
• Turn the printer off for at least 15 minutes

The manual for a related printer suggests that you have a printer failure issue. If the paper lights are off, then it is a scanner failure. If the paper lights are also blinking, then it's a fatal error. Turn off the printer, unplug the unit and then wait one minute. Plug it back in and turn it on, if the lights keep blinking then call HP support. (If it is under warranty, then it may be worth fixing.)

If I misunderstood your post and the power light is steady but the other lights are blinking, then you may have the cover incorrectly positioned or something blocking the ink carriage. Open it up and check for anything out of place.

I hope this helps.

This is a temperature error, and may be caused by a defective print head. If replacing the print head does not fix it, the main board is defective.

Buttons and lights on the printer Two buttons and three lights are located on the front of an HP Deskjet printer.

• The lights tell when the printer is working or when it needs attention.
• The buttons help control the printer.

Buttons and lights Purpose POWER button and light Push the POWER button to turn the printer off and on. When lit, the light shows that the printer is turned on. RESUME button and light The light blinks when there is a problem with paper. When the problem is corrected, press the button. Print cartridge light The light blinks when there is a problem with a print cartridge. When the problem is corrected and the top cover is closed, the light will stop blinking. Troubleshooting blinking printer lights Blinking lights Reason

All lights are off. The printer is off (asleep).

Press the POWER button to turn the printer on.

The printer should turn on automatically when a print job is sent to it.

The POWER (top) light is on. The printer is idle.

The printer is ready to print a document.

The POWER (top) light is blinking. The printer is busy printing.

Allow enough time to print. When a document has many fonts or graphics or uses complex color such as a color photo, it takes longer to begin printing.

The PRINT CARTRIDGE (bottom) light is blinking. Possible causes:

• The front cover is open. Make sure the front cover is completely closed.
• The print cartridge is missing. Make sure the print cartridge has been installed correctly.
• The print cartridge is broken or incompatible. Lift the front cover, and wait for the print-cartridge cradle to slide out. Check the part numbers on the print cartridge:

Black: 51645A

Color: C1823D,

If the print cartridges are compatible and correctly installed, they may be defective. Try replacing the print cartridges.

If none of the above suggestions fix the problem, and, if the error message still occurs, it may be a hardware failure. Call the HP Customer Support Center.
