Question details

The user needs to restore recent edits in a Microsoft Word document that were lost due to an unexpected computer shutdown from a battery failure.

Product: Microsoft Word
Device & OS: not provided
Scenario: Document recovery after sudden power loss or battery failure.
Observed behavior: Word reopens an older version of the document, and recent changes appear missing despite AutoSave being enabled.

Before you start

Ensure your computer is plugged into a reliable power source before attempting recovery to prevent another unexpected shutdown during the file restoration process.

Solution 1Recommended

Use Word's Recover Unsaved Documents Feature

This built-in feature is the fastest way to retrieve drafts that were interrupted by a power failure or system crash.

Microsoft Word's AutoRecover feature continuously saves your progress in the background. When your computer shuts down unexpectedly, Word stores these backups in a dedicated UnsavedFiles folder.

Open File Options

Launch Microsoft Word and click on the 'File' tab located in the top-left corner of the window.

Navigate to Manage Document

Click on 'Info' in the left-hand sidebar, then select the 'Manage Document' button.

Recover Unsaved Documents

Select 'Recover Unsaved Documents' from the dropdown menu. This will open a file explorer window pointing to the UnsavedFiles folder.

Open the .asd File

Look for files with a '.asd' extension. Select the file corresponding to the time of your battery failure and click 'Open'. Once opened, immediately click 'Save As' to secure your document.

Verify AutoRecover Settings: To prevent future data loss, go to File > Options > Save and ensure 'Save AutoRecover information every X minutes' is checked and set to a low interval (e.g., 5 or 10 minutes).

Solution 2

Restore Previous Versions from OneDrive

If your document was saved to OneDrive or SharePoint, you can use Version History to revert to a recently synced version.

Solution 3

Search for Temporary (.tmp) Files

When standard recovery fails, manually searching for temporary files created by Word might help you recover raw document data.

Frequently Asked Questions

Where are Microsoft Word AutoRecover files stored?

By default, AutoRecover files (.asd) are stored in C:\Users\[YourUsername]\AppData\Roaming\Microsoft\Word\ or C:\Users\[YourUsername]\AppData\Local\Microsoft\Office\UnsavedFiles. Note that the AppData folder is hidden by default in Windows.

How often does AutoSave/AutoRecover save my work?

By default, Microsoft Word's AutoRecover saves your document every 10 minutes. You can adjust this interval by going to File > Options > Save and modifying the minutes next to 'Save AutoRecover information every'.

Why didn't Word's AutoSave work when my battery died?

AutoSave applies primarily to files continuously syncing to OneDrive or SharePoint. If the file was saved locally, it relies on AutoRecover, which only saves at specific intervals. If the battery failed between these intervals, the most recent unrecorded changes may be lost.

Can I recover a Word document if AutoRecover was turned off?

If AutoRecover was disabled, your best option is to check the Windows Temp folder for temporary files (.tmp) created while the document was open, or check your cloud storage version history if the file happened to be stored online.
