Question details

The user needs to stop their Surface Pro 8 from overheating and generating loud fan noise when editing Microsoft Word documents stored in OneDrive for Business.

Fix Word Causing Surface Pro 8 to Overheat When Editing OneDrive Files

Product: Microsoft Word, OneDrive for Business
Device & OS: Surface Pro 8, Windows
Scenario: Editing cloud-synced documents in Microsoft Word via a OneDrive for Business account.
Observed behavior: CPU usage spikes between 70% and 100%, causing the device to overheat and the fans to spin rapidly. This behavior does not occur when editing locally stored files or using a personal OneDrive account.

Before you start

Ensure your Surface Pro 8 is placed on a hard, flat surface to allow for proper ventilation, and temporarily pause your OneDrive sync to prevent data conflicts while troubleshooting.

Solution 1Recommended

Save the Document Locally to Bypass Sync Issues

Moving the file to your local drive prevents continuous background syncing with SharePoint or OneDrive for Business, which is the primary cause of the CPU spike.

Since the overheating issue is isolated to OneDrive for Business and SharePoint files, copying the document to your local machine will immediately stop the continuous network synchronization attempts that are straining the CPU.

Save a local copy

Open the affected document in Word, click on 'File' in the top-left corner, and select 'Save As'.

Choose local destination

Select 'This PC' or 'Browse', and choose a local folder such as your Desktop or Documents folder.

Edit and upload later

Continue editing the file locally without overheating issues. Once finished, manually upload the updated file back to your OneDrive for Business folder.

Temporary Relief: This acts as an immediate workaround to keep your device cool while Microsoft investigates this specific OneDrive for Business synchronization bug.

Solution 2

Run Word in Safe Mode and Disable Add-ins

Safe Mode launches Word without background extensions, helping identify if a third-party add-in is conflicting with OneDrive for Business and causing the high CPU usage.

Solution 3

Check for Office and Windows Updates

Applying the latest patches can resolve known bugs related to Office sync processes and background AI tools that trigger high CPU utilization.

Frequently Asked Questions

Why does OneDrive for Business cause Word to overheat on my Surface Pro 8?

This is often due to a bug in how Word continuously synchronizes changes with SharePoint or OneDrive for Business servers. Background AI processes and auto-save features constantly communicate with the server, leading to 70-100% CPU usage which naturally increases the device's temperature.

Does this high CPU issue also affect Microsoft Excel or PowerPoint?

Typically, no. Based on most user reports, this specific aggressive syncing behavior and resulting overheating seems strictly isolated to Microsoft Word when handling business cloud files. Excel and PowerPoint generally perform normally under the same conditions.

Can pausing OneDrive sync fix the Word overheating issue temporarily?

Yes. Pausing your OneDrive sync from the taskbar icon can temporarily stop the background communication that causes the CPU spike. However, the most reliable workaround until a patch is released is saving a copy of the document to your local desktop to edit.
