Question about HP Compaq Presario 7AP135 PC Desktop

1 Answer

I am unable to turn the computer on. There is nothing wrong with the electrical outlet or the power strip that I am using. The power button on the computer does not have any tactile response. Could the power button be defective? Could there be something wrong with the computer's internal power supply?

When I turn on my Sony TV, ti stays on about 30 seconds then shuts off, What do you think is wrong?


Do a Power Reset.
1. Turn off TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.
If issue persists after doing the steps, reset the TV to factory default settings.
1. Turn on the TV.
2. Using the supplied remote, press and hold the UP arrow button.
3. While holding the UP arrow button press the POWER button on the TV itself.
4. When the TV goes off, release the POWER and UP arrow button.
5. The TV will turn on by itself and the initial setup screen will be displayed. Just follow the on-screen prompts to finish the setup.

When i cleaned my dell demension i put everything back exactly how it was now when i turn on my computer none of my external devices mouse pc screen keyboard is not turning on i need help


I would first check and verify that the electrical outlet or power strip that they are plugged into is working. If a plug gets in a bind it could have blown a fuse on the power strip or the power strip might have a reset switch on it. Or the power strip might have failed. If you have a uninteruptable powersupply that you plug everything into you will need to confirm that it is working as well, test it and look for reset buttons or a fuse holder on it. Your electrical cords could have been pulled out from the wall outlet itself while cleaning sometimes even wall outlets if put in a bind from pressure will blow a fuse or the cord might pull out just enough that it is not making a good connection.
You might get a lamp with a bulb that you know works and plug it into the same electrical receptical that you have the dell computers power cord plugged into and then test the monitor power source the same way.
If the outlets or power strip are getting power and that is confirmed by testing them, and then you plug in the Monitor and Dell power cords into the sources that you have confirmed are getting power, and they do not come on we have a different problem.
If the monitor is hooked up wrong to the computer or not even hooked to the computer the light should come on on the front of the monitor incicating that it is getting power. If you plug it into a confirmed working electrical outlet the light should come on on the power button of the monitor. If it does not come on then somehting might hve possibly damaged all of the epuipment that was plugged in like a power spike on the electrical lines going into your home, this would be very rare but not impossible.
I am sorry for all of the senerios but you were not really clear on what you were using as power sources going to the equipment and I wanted to try and cover the most common possibilities in one email. Please let me know if this helps

Power failure


by plugging it directly into the wall... what was it plugged into before. and have you actually taken some other electrical device and plugged it in to make sure the wall socket is still live.
there is also a reset button on most power strips... it may have tripped.

Try those and let us know.

Printer doesn't turn's on


Per Canon:

Solution: Disconnect and Reconnect AC power adapter or power cord to the device and electrical source

Secure all Power Connections
  • Disconnect the AC Power Adapter or power cord from both the device and the electrical source.
  • Then reconnect it.
  • If you are still unable to obtain power to the device, try another power outlet.
  • If possible, try connecting power directly to a wall outlet (as opposed to using a surge protector or power strip...just as a troubleshooting measure).
If this does not work, have you tried a different outlet to ensure that the outlet isn't the issue? Also, when you press the POWER button, does the printer respond at all, or is it basically dead?

Please post back if you need further help, otherwise, thank you for using and rating FixYa!
