Your power supply is probably bad. Try plugging in directly to the wall and try it. If you have a meter, you can open it up and turn it on. Check the voltage on one of the unused plugs coming out of the power supply, the box in the back with the a/c receptacle on it. Find a plug with a yellow, 2 black and a red wire. Yellow/Black should be 12v, Red/Black should be 5v. Normally people lose the 12v (get only 8v) so the motherboard comes on but not the HDD.
If your prw supply tests OK remove any cards you have and try turing it on with no cards. If it powers on, add the cards back one at a time until it won't power on and that card is bad. Normally this would be a modem card that connects to a phone line.
If the pwr supply test bad, take some pictures of the inside with your phone and remove the power supply (4 screws on the back) and disconnect all the cables that go to it. Check the label for watt ratings and a part number or take the whole P/S to a computer store where they will be $45. Make sure the one you buy has the same type connectors, same or more watts and screw holes in the same place (ask for help). Or you maybe able to order online using the HP part number ($80) or from eBay. Replace the power supply, plug everything back in and turn on. Really pretty easy.

Hi,

Have you tried to power the machine without the surge protector? This will enable you isolate the issue. If your motherboard is off when you turn on the power, then it sounds like your power unit got fried. Just replace the power unit and you should be ok.

Won't initialize or start


Hi Kathleen Morris,

I would be happy to help you with your Officejet Pro 276dw. I understand from your description that is gets stuck in a loop and will not start or initialize.

I suggest using the following link to ensure you have the latest firmware update: http://h20565.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5273948&swLangOid=8&swEnvOid=4182

Also, do you have the printer connected directly to a wall outlet or is it in a surge protector or power bar? Even if you have been using a surge protector/power bar all this time and you feel it is not the cause, please connect it to a wall outlet just so we can eliminate the power source as the root cause. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector In this document you will see, ISSUE: Problems or issues may arise when an HP LaserJet series printer is connected to an uninterruptible power supply (UPS), a power strip, or a surge protector
^ This is not limited to Laserjet printers.

I hope this helps.
I work on behalf of HP.

No power cannot turn on


Suggest you check the simple stuff first.

Not checking is akin to a car that won't start, and tearing apart the entire fuel system, only to find it was just out of gas.

1) Make sure the receptacle the surge protector is plugged into, has power. Surge protector Power On light should be lit.

2) Check THE receptacle in the surge protector, that the computer itself, is plugged into.
Have had a number of expense surge protectors, where just THAT receptacle was bad.

("Hmmm, surge protector Power On LED light is lit. Monitor, printer, sound system, and router plugged into the surge protector has power. Should be good to go.

NOT!
Plug a table lamp, or similar device into THAT receptacle.
Make SURE it has power)

Surge protector, and receptacle in surge protector checks out?
Bypass the Power On switch.

See if the problem is a $5 Power On switch, or the Power Supply.

(Generic ATX Power On switch that I have found fits many computers,

http://www.directron.com/atxswitch.html

{The Power On switch, is located inside the plastic Power On button assembly}

This is information about computer Power Supply's,

http://en.wikipedia.org/wiki/Computer_power_supply

This is a basic example of an SMPS, (Photo at upper right. You can click on the photo to enlarge), and info about.
(Switched-Mode Power Supply. The main type of power supply used in personal computers),

http://en.wikipedia.org/wiki/Switched-mode_power_supply

By bypassing the Power On switch, you will be able to determine if the problem is the switch, or Power Supply.

Bypassing the Power On switch turns the Power Supply on?
Bad Power On switch.

Bypassing the Power On switch does Not turn the Power Supply on?
Bad Power Supply.

A jumper wire is used on the 20, or 24-pin ATX main power cable.
The jumper wire goes to the Soft Power On, (PS_ON. Green in color), to ANY Ground wire.
(ALL Black wires are Ground wires)
A MOMENTARY contact is used.

(Example of a 24-pin ATX main power cable, and it's respective connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24 )

In order to guide you in this procedure, I need to know the computer manufacturer name, and Model Number.

On a desktop computer this will be located on the Back of the computer tower, (Next to the Windows product key), or up on the side of the tower.
Some models have it where there is a door you open in the front, and the product number, or model number is located there.

Tower won't turn on


Brandi,

Please check the following:

1. Make sure the the surge protector is securely plugged into the wall. Test this by plugging in a light / lamp to it, to make sure it's working.
2. Make sure that the surge protector is turned on.
3. Check to make sure that the power cable from the computer to the power surge protector is securely plugged in.
4. Check to see if the computer will power on now.

5. If this still isn't working, remove the power strip/surge protector and connect the computer directly to the wall.

6. If this STILL isn't working, try plugging your computer into a different outlet in the house to see if the outlet in your home might be bad.

6. If your computer STILL isn't powering on then I'm afraid the worse has happened, which is one of the following issues:

1. Bad power supply (they are cheap, around $20-40)
2. Bad motherboard (they are sort of pricey, around $50-200)
3. Bad CMOS battery (they are cheap, around $5-10)

I can fix all of the above and order parts for all of the above, if you are in need of parts.

I hope this troubleshooting guide helps you! If this resolves your issues, please mark this question as resolved and select my answer. This will assure customers that I can help them with their issues.

Thank you,

Blinking green light front and back. Clicking sound from inside.


Do you mean the little green LED light near where you plug the power cable into the back of the computer? If that's the blinking light then unfortunately, this means that power is getting to the power supply but it is not going from the Power Supply to the Motherboard/Devices. The power supply is broken and is not converting the power from the wall to the proper voltage for the Motherboard/Devices. You will have to replace the power supply.

Call HP, and I hope you are in warranty and get it replaced for free or you can order the exact same one from HP that originally comes with that model. 1-800-HP-INVENT for their tech support line.

Power issue


Sounds like your power supply may be shot on your computer. You can get a power supply tester and check it. Not sure what to do about the printer. If you had a surge protector in between your computer and ac. Plug the computer and printer back in to the AC outlet directly and see if that helps. Hopefully only your surge protector is damaged.

Please rate, Thanks.
