Solved!

My HP Envy All-in-One started having 4 fast beeps followed by 3 short beeps!

HP Recommended
Envy Quad AIO
Microsoft Windows 10 (64-bit)

My HP All-in-one Desktop, for no reason at all, recently started up with 4 fast beeps followed by 3 long beeps & after doing that 4-5 times goes to a black screen saying "unsupported adapter installed" & then shuts down. Can anyone help with this since there doesn't seem to be any published date for this?

@khearrean 

Even though All-in-Ones are considered desktops, in reality, they are oversized laptops but with external mouse and keyboard -- so they suffer from the same limitations as laptops, including overheating.

 

Unfortunately, that error code means the AIO has overheated and shut down.  That is supposed to correct itself after cooling down -- presuming no damage was done -- and that is supposed to be the case because there are thermal sensors that will power it off if it overheats.

 

But if it is not turning on, it may be suffering other hardware failures due to the overheating.  

 

To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

To contact HP Support see the following link to create yourself a case number, then call and it may help speed up the call process:

Step 1. Here is the link: https://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options - click on Get phone number

Case number and phone number appear.
--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
https://www.service-center-locator.com/hp-hewlett-packard/hp-hewlett-packard-service-center.htm

If that link does not get you a useful page, then use the main HP link:

Good Luck

Well, guess what? I took my unit w/ power-cord to my local PC shop & they immediately plugged it up & it powered up pretty as you please! Turns out the power-strip I had it plugged into somehow became faulty, so he advised me to plug it in directly to the wall outlet. So when I got back home, I did & bingo; powered right up! That however brought up another mystery, which is the couple other components plugged into the same strip work just fine...weird! But that’s ok; my PC is fine & all that matters.. but thanks for the response.
