There are a few possible reasons why your Photosmart 7520 printer may be shutting off after only 4 seconds:

  1. Power supply: If the power adapter light is turning off, it could indicate a problem with the power supply. Try unplugging the power adapter from both the printer and the wall outlet, then plug it back in and try turning the printer on again. If the problem persists, you may need to replace the power adapter.
  2. Overheating: If the printer is overheating, it may shut off as a safety feature to prevent damage. Make sure the printer is not in direct sunlight or near a heat source, and that it has adequate ventilation. You may also want to try turning the printer off and letting it cool down for a while before trying again.
  3. Hardware failure: If neither of the above solutions work, it's possible that there is a hardware problem with the printer. This could be caused by a variety of factors, such as a faulty power button or a malfunctioning circuit board. In this case, you may need to take the printer to a repair shop or contact the manufacturer for support.
It's also possible that there is an issue with the printer's firmware or software. Try updating the firmware and drivers to see if that resolves the problem. You can find these updates on the HP website.

You will have to check the equipment driver itself. While attempting to print, try changing the page size (go to page setup). This will give you an idea.

I have an ASPIRE 7520/7220 series laptop(17").

yeah, make sure the CPU is not getting heated, check for any loose connections, check the power supply is working, if this is a new computer and it has warranty, I advise to take it back and have it checked or replaced by a professional.

3- Press and hold # and 6 on printer while plugging the power cord
4- Printer may shut off itself
5- Press power button to turn it on
6- Select country and language
7- It will clean and align itself. May take 7-9 minutes
8- It will print an alignment page, place the alignment page on scanner glass and press ok

Hello sir,my laptop is acer aspire 7520 no charging,no run on main,run on battry only,laptop power adaptor led is damage,

this could be due to the fault in the ac adapter,please try swapping another adapter if it works then you need to replace your adapter.

Shut off and won't come back. It's like it is dead.

follow this procedure:
1. unplug the ac adapter and keep it unplugged.
2. Remove the battery and keep the battery unplugged.
3. Hold the power button down for 15-20 seconds(Nothing will appear on the display and none of the lights will light up)
4. Release the power button and plug in the ac adapter ONLY. (A power indicator light should be lit on the ac adapter when it is plugged in)
5. Normally power on the notebook.
6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
7. Plug the ac adapter back into the system, the battery charging indicator light will light up. If the battery indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

Asus ac adapter will not wrk green light on adapter

First check the wall socket make sure you are getting power, plug a lamp into it for instance. If there is no green light on the adapter then it is bad and you will need to order a new one from your computer manufactor.
