Product
Adobe Acrobat
Device & OS
Windows
Scenario
Editing a PDF file stored on a domain network server when the laptop goes into and resumes from standby mode.

Before you start

Solution 1Recommended

Adjust Auto-Save Settings and Edit Locally

Change the auto-save interval to a shorter duration and work on local copies to avoid network dropout issues during standby.

Network interruptions during system hibernation or standby can corrupt the temporary files Adobe Acrobat uses to track changes.

Editing a local copy of the file and syncing it to the server later prevents Error 109 from occurring when the server connection drops.

1
Copy file locally

Before editing, copy the PDF from your domain network server to your local Desktop or Documents folder.

2
Open Preferences

Open Adobe Acrobat, click on 'Edit' in the top menu bar, and select 'Preferences'.

3
Adjust Save Settings

Select 'Documents' from the left-hand pane. Under 'Save Settings', ensure 'Automatically save document changes to temporary file' is checked and set the interval to 5 minutes.

4
Save before standby

Manually save the document by pressing Ctrl + S before walking away or closing your laptop lid to enter standby mode.

Frequently Asked Questions

What causes Adobe Acrobat Error 109?

Error 109 typically indicates a problem reading the document. This often happens if the file gets corrupted during a save process, if network connectivity drops unexpectedly during sleep mode, or due to incompatible third-party browser plugins.

Can I recover my PDF if it turns blank after Windows standby?

If the PDF appears blank upon waking your computer, do not save over the file. Close Acrobat immediately, ensure your network connection is restored, and reopen the file. If the file is corrupted, you may need to restore it from a server backup or previous version.

How do I ensure my mapped network drives reconnect after sleep mode?

You can configure Windows to automatically reconnect mapped drives by ensuring the 'Reconnect at sign-in' box is checked when mapping the drive. Alternatively, your IT department can enforce a Group Policy to keep network drives persistent across standby states.
