Hello harley,

 

For your security, remove the Serial Number from your post. Go to Options and choose Edit from the dropdown menu.

 

That is an All in One type of computer. Not much you can do with those.

Check the power cord. Plug it into a different outlet, NOT a power strip to see if you get power.

IF no power, it could be several things hardware related internally.

It has an external power supply (DC converter block on the cord) and it could be faulty.

 

You can also take a look at the HP trouble shooting guide.

 

If the computer is still under warranty, you will need to contact HP Support for your area.

Re: HP pavilion 23 all in one won't turn on

The solution I found which worked to cure this problem was to replace the CMOS battery on the Motherboard.

 

To do this, follow the instructions below:

 

Disconnect anything connected to the Monitor; i.e. mouse, keeyboard, power supply etc.

 

Place the Monitor on a hard flat surface with the Monitor glass side down and back side facing up - protect the glass side by placing a towel or something like that on the hard flat surface first.

 

Release the two screws on the back of the Monitor - they are captivated so will not come out.

 

Ground yourself by touching something metallic - like a radiator and then do not move about too much.

 

Gently prise the back cover off the  Monitor all way round and remove the cover.

 

The CMOS battery is on the Motherboard which is on the right hand side under a large nmetal cover.

 

Remove the two screws retaining the metal cover - look at the cover, the location of the screws are marked with arrows.

 

The cover then pivots from left to right in order to remove it.

 

The CMOS battery is the the only shiny button shaped item on the Motherboard.  Carefully prise it out of its socket - idealy with something plastic. 

 

Make a note of which way round the battery is to be fitted.

 

Replace the battery with the same type, voltage etc or an exact equivalent.

 

Re-fit the Motherboard cover and rear cover of the Monitor.

 

Job done for the cost of a £1 GBP battery.

 

Just a note - this is the second HP PC I have repaired with this type of fault - the other one was a Laptop!

 

Hope this helps anyone else with a similar problem - what have you gor to loose for the price of such a low cost item!!
