AZ3-715-UR61: Wont Power Up After Power Outage

Computer was on, then power went out and came back on quickly. Once router was powered up i tired to power up the computer and no go. It was plugged into the same surge plate as the router and every other thing plugged into the surge plate works as it did before the power outage. I tried unplugging and replugging in the ac/dc adapter and using a wall plug but nothing works.

When i press the power button theres no sign of anything starting up at all. Is there any kind of reset function? or some procedure to get computer to power up?

Unplug the charger. Gently insert a paperclip into the battery disconnect pinhole on the bottom for about one minute. Plug the charger back in. But wait for the battery charge LED to turn from solid orange to solid blue. Then try to turn the laptop on again.

Thanks Jack,

But this is a all-in-one PC so there isn't a pinhole on the bottom of it although i wish there were. Still hoping theres a reset function but not holding my breath. Ordered another ac dc adapter.

Sorry, Are you sure of the model number? I only find the Aspire Z3-771 All-in-One. Or perhapst a Veriton All-in-One?

johnrm

Sorry bout that. Its a AZ3-715-UN61

Unplug the adapter. Press & hold the power button for about a minute, Keep an eye on the power LEDs while plugging the adapter back in, then while pushing the power button. Does the LED flash, blink or otherwise show any life now?

Jack,

I tired this as well yesterday and it didnt work. My adapter doesnt have LED lights so i cant whether its dead .

JackE

I meant the monitor's LEDs, not the adapter.?

johnrm

Morning Jack,

The monitor LED showed no sign of life which leads me to think that the adapter is toast...

JackE

Do you have a multimeter to check it's output voltage between the plug barrel and center hole? Should be about 19volts. If dead, google the part nos. are either KP.09003.005 or KP.0900H.001. About $35usd.

Thanks,

i dont have a multimeter but i did found this replacement on amazon: https://www.amazon.com/gp/product/B00B8EEPJE/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1

And should have by 5/5. Sure hope it fixes things otherwise its replacement time and i dont want to spend the $$$ let alone recovering everything off the drive

Good luck. Ir's unusual that the PSU would react to a power outage unless there was a fairly large voltage spike or surge when the power came back on. However, this usually causes damage to more delicate devices downstream of the PSU without a mains surge protector. I'll keep my fingers crossed for you. If you order the PSU from Amazon, you might also want to consider picking up a fairly inexpensive digital multimeter at the same time. They can save you money in situations like this especially if the charger is in fact OK and something else failed.

Also be aware the surge arrestors have a service life, each time there's a little fluctuation in the power (normal in most environments) the components degrade slightly. I typically swap mine out for new about every five years. When they get degraded enough the symptom is they let the surge through to your equipment and then it's too late...

Jack if not the PSU then what should i check? The power went out for less then a minute and came back on pretty abruptly so i think thats what did the PSU in. As i mentioned nothing else in the house suffered from the outage which was strange.

Bill: the PC is about 10 years old and i bought it as a refurb, with a 2003 production date so that could mean the PSU is almost 20 years old.

Thanks again for the help and and im curious to hear what next steps i might need to take if the PSU isnt the culprit.

Interesting. New z3-715 debuted about 6 years ago. Are you sure that you have a z3-715?

billsey

He says A23-7 in the thread title, if the system is close to 20 years old the model numbering would be quite different than what Acer uses now. Our assumption it is a AZ3-7xx might be wrong...

JackE

johnrm>>> Its a AZ3-715-UN61>>>

Yeah, that's why his earlier response needs to be re-checked.

johnrm

Yes, i missspoke about age. i took delivery in 2017. Got my amazon adapter but it has the wrong tip configuration and wont plug into the PC. Can i change the tip?

Ive been w/o the PC for a week now and dont even know if the adapter is the problem. this is pretty frustrating.

JackE

Is the color code also yellow on the old PSU tip?

johnrm

the original is orange, and the replacement is yellow. the difference is that the hole diameters is smaller on the yellow one.

billsey

Yeah, we really need to figure out what system you actually have, so we can help get the right supply. The full model number should be on the same sticker than has the SN and SNID. It should be something like Z3-7xx-xxxx, although the numbers and letter could also be different.

The power plugs come with different hole sizes and a too big hole won't work as, well as a too small hole. Same with the outside diameter, though there are few options usually found with those.
