All in One will not power up

[johnskipp]

My All-In-One will not boot up.

No pilot light or any sounds.

Power supply checks out, - 19.5v DC at the plug.

Tried the 'Bot' assistant and power reset, no luck.

Does any one have any suggestions please ?

thanks

@johnskipp There could be an issue with the power connector that connects to the adapter, the best way to confirm the issue, is to simply check if the device powers on when connected to another wall outlet, also, if that doesn't work, I have a few recommendations that will:

(simply select your description of the issue from the bottom of the screen to gain access to the next set of steps that should resolve your concern).

If the issue persists, follow the below steps:

Step 1: Remove discs and devices

Before troubleshooting startup issues, remove or disconnect all discs and devices from the computer.

1. Turn off the computer.

2. Remove any discs and USB devices.

3. Remove memory cards from the card reader slot.

4. Disconnect all non-essential devices such as printers, scanners, external hard drives.

5. Leave only the mouse, keyboard, and monitor connected.

After you have removed all discs and devices, turn on the computer.

• If the computer starts, reconnect devices one at a time, to determine which disc or device is causing the problem. If the issue is solved, troubleshooting is complete.

• If the computer still does not start and exhibits the same problem, press and hold the Power button to turn off the computer. Do not connect anything, and then continue troubleshooting.

As mentioned in my post, -

the power adaptor is providing 19.5v at the (PC-end) plug,

already done the power reset,

already been thro the troubleshooting 'bot', and " Advanced Startup Troubleshooting "

There are no peripherals connected.

There are no sounds and no power light,

I'm all out of on-line guidance checks.
