Ok last night my hp all in one unplugged while on and when I went to start it back up, it began beeping….two different semi long beeps and screen won’t come on. What is going on and how can I fix it?

A list of beep codes is here be sure to expand the bios sections at the bottom.  The suggestions on what to do are good.

 

That being said, frequently the motherboard manufacturer has their own beep codes as sort of mentioned in that bios section.

 

Should have been on a surge protector, but if unplugged from it then the protector not useful.

 

I am not familiar with "all in one".  Is there a cover in the back where memory slots can be accessed?  If so, reseat the sticks of memory.  Since the display does not turn on there is a real problem and not just a stuck key on the keyboard.
