Desktop powers down after short break of inactivity

HP Recommended
HP Slimline Desktop 270 a016

I have a HP Slimline Desktop 270 a016 and notice that the computer powers down and off after a very short time of inactivity and have to completely reboot and turn on computer with button to use again each time.     Have had previous HP desktops where computer stayed on all the time and only had to hit a key or mouse to access computer without rebooting.    Is there a way to set it up that way or increase the length of time the computer stays on if I have to leave for a period of time?


Thank you

Thank you for posting on HP Support Community.


Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

  1. In Windows, search for and open Power Options.

  2. Click Choose what the power buttons do.

    Figure : Choose what the power buttons do

    Power Options window with Choose what the power buttons do highlighted
  3. Click Change settings that are currently unavailable.

  4. In the Shutdown settings section, make sure the check boxes next to the shutdown options you want to see in the shutdown options are checked.

    Shutdown settings with Sleep and Hibernate checked and highlighted
  5. Click Save changes. The options you chose are now displayed in the shutdown options.

To adjust the amount of time before your computer enters Hibernate Mode, do the following:

  1. In Windows, search for and open Power Options.

  2. In the Choose or customize a power plan window, click Change plan settings next to the plan you want to change.

  3. In the Change settings for the plan window, click Change advanced power settings.

    Figure : Change advanced power settings

    Change advanced power settings highlighted
  4. Click the plus sign (+) next to Sleep to expand the list, then click the plus sign (+) next to Hibernate after.

  5. In the Setting (Minutes) drop-down box, set the time for the computer to be idle, in minutes, before the computer goes into Hibernate Mode.

  6. Click OK, then click Save changes. The computer hibernates after it has been idle for the specified amount of time.

Hope this helps! Keep me posted for further assistance.
