Be careful because that other PSU has higher amp output. You don't want to fry things...
And/or you might get a warning that it's not the "recommended" PSU and it might refuse to boot with that one.

I am thinking of trying a new power supply as next step. The current power adapter is Dell # HA65NS5-00. It is 19.5 V and 3.34 Amp output.
I have a Dell laptop adapter that provides 19.5 V and 4.62 amp output. It is PA-10 Family.
Would it be ok to try it using this adapter? I thought since it is bigger, it would be ok.
Since the voltages match, it should be ok. Right, higher Amps is OK because it only draws what it needs.
The AiO might still complain about it's digital-identity if there is an AC-Adapter white-list.

1. I checked the output of the external power supply and it showed 19V before the battery in my multimeter died. I'll be checking the amperage as soon as I replace it.
2. Things to know:
- We had power fluctuations (brown outs) earlier this week during a storm.
- The surge protector got turned off. That's actually how the PC got shut off. I've been unable to power-up since.
1. Right, initial volts check is correct. However, the volts of the SMPS really need to be checked while there is a full-load on it.
Since this is a "laptop like" power system, there is likely a "Power Board" inside (DC-DC Converter) ... so check it's outputs.
2. All my desktops (and TVs, Home-Theater, etc.) get a good UPS with not only a battery but also voltage-regulation (like a nice mid-level consumer-class APC unit). They have saved me many times. Misc smaller devices without them eventual die during storms.
Open a cheap Surge Suppressor sometime ... you will see there is basically nothing inside. Your only hope there is that they will act like a fuse and self-destruct.

You measure the voltage of the SMPS output-side. When the SMPS is securely sealed, I've done it from the back-side of the main-DC-power-In connector (inside the machine itself).
If you are not a trained electronics or appliance technician, you should not be trying this. :Smile:

2. I have an HP 854057-001 that has same diameter plug and plugs in but is slightly longer. It says it is 19.5 v and 3.33 A and 65 watts. I plugged it into the computer and no light on the computer.
3. It looks like the Dell computer is 15 months old. (3 months out of warranty).
Do you have any other troubleshooting ideas for no power at computer? I am afraid it is a board problem.
1. OK
2. I don't know about all that. You said you wanted to use :
I have a Dell laptop adapter that provides 19.5 V and 4.62 amp output. It is PA-10 Family.
which would have been fine for a test
3. Yeah, I can't teach you to be a computer technician in a forum. Google and YouTube are good. If you have a specific question, feel free to ask. You could have a local qualified computer technician take a look at it. Best Buy is sometimes OK if they have smart techs that care.
I wrote this a while back. It's Dell focused and purposely not too technical, but it's for desktops ... the All-In-Ones are really more like a giant laptops.
