Green light blinking

[Anonymous]

My desktop won't turn on. There is a blinking green light by the power cord behind the tower. I have tried unplugging my power cord, pressing and holding the power button for ten seconds, and then plugging the power cord back in; this did not work. There is also no voltage switch.

The only solution I've come across for a non-tech savvy user like me is to use a hair dryer to blow hot air into the fan vent by the power source. This solution definitely works for HP Pavillon but I am unsure if it will work for an HP Envy 700. My fan vent is further below unlike the HP Pavillon. Should I try to blow hot air into a vent, and if so, which vent do I use? The vent by the power source or the fan vent which is located below?  Here is a picture of the back of my tower.

I have not tried yet because I don't own a hair dryer, so I will have to go out to the store after work tomorrow to buy one. Please give me your thoughts in the meantime.

This is a great location to get assistance! I read your post and see that you are getting no power issue on  HP Envy 700 Desktop. I would like to help you resolve this issue.

Perform a hard reset.

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset." Use the following steps to perform a hard reset on a computer:

1. Turn off the computer completely; disconnect the power cord from the back of the computer.

2. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

3. Reconnect the power cord and turn on the power.

If the issue persists,

Let me know how it goes.

Cheers.

Hi sandytech20,

Thank you for the reply. Unfortunately, unplugging the desktop and holding the power button for 5 seconds before replugging the desktop did not work for me. I have also tried unplugging the desktop, pressing the power button once and waiting for 10 seconds before replugging the desktop also did not work for me.

Are there any other methods?

The blow dryer technique does not work. I was aiming the blow dryer at the bottom vent for at least 1 minute for several times. Was there something I was doing wrong?

It looks like you were interacting with @sandytechy20, but he is out for the day & I'll be glad to help you out, 

I'm the Riddle_Decipher & I'm at your service. 

As described in the article shared by the previous tech, if the light on the back of the PSU is flashing - (it should not flash with all connectors removed), plug the power cable into a different power outlet that is known to be good. If the LED still flashes, the power supply should be replaced.

I recommend you Contact HP to have it either replaced:

HP Technical Support can be reached by clicking on the following link: http://h22207.www2.hp.com/us-en/?openCLC=true

(1) Once the support page opens please select the country in which you're located. Next, enter your HP model number on the right.

(2) Next, choose the 'Contact Support' tab at the top and scroll down to the bottom of the 'HP Support- Contact' page to fill out the form provided with your contact information.

(3) Once completed click the 'Show Options' icon on the bottom right.

(4) Lastly, scroll down to the bottom of the page and select 'Get the phone number.' A case number and phone number will now populate for you.

They will be happy to assist you immediately. 

If the unit is under warranty repair services under the manufacturer's warranty will be free of charge.

If I have helped you resolve the issue,

Hi Riddle_Decipher,

If I contact HP, does this mean that I will have to mail the desktop for servicing? Or will HP send out a replacement battery? My four-year old unit is no longer warrantied.

I was thinking about bringing the desktop to Geek Squad at Best Buy. Does this seem like a decent option, or will they not know how to fix the desktop?

Thank you for responding,

It's great to have you back 😉

HP would recommend replacing the Power Supply Unit (PSU) and you could do that either by shipping it off to HP or by replacing it on your own,

Click here to find the universal part number for your PSU and you may order it either on the HP Parts Store or the local retailer such as best buy etc...

And yes, alternatively you may have it repaired by the geek squad as well, they should be able to help you out too, I hope.

I hope you have a good day ahead,

And Feel free to ask any other queries as  well,

Considering, this forum has some of the best people in the world available and ready to help.
