Chromebooks are fast when new but can slow down significantly over time. The causes are usually software-related, not hardware — which means most slowness is fixable without buying anything new. Here are the 10 most effective fixes, starting with the quickest.

Fix 1: Close Tabs You’re Not Using

This is the single most common cause of Chromebook slowness. Each open Chrome tab uses RAM. Chromebooks typically have 4GB or 8GB RAM — 20+ open tabs will saturate it. Close tabs you’re not actively using or use a tab manager extension like The Great Suspender to automatically freeze inactive tabs.

Fix 2: Disable Unnecessary Chrome Extensions

Extensions run in the background and consume CPU and RAM continuously. Open chrome://extensions and turn off every extension you don’t regularly use. Even well-made extensions add overhead. Removing 5–10 unused extensions can make a noticeable speed difference.

Fix 3: Clear Cache and Browsing Data

A bloated cache can slow Chrome significantly on devices with limited storage. Press Ctrl + Shift + Delete → set time range to “All time” → check “Cached images and files” and “Cookies and other site data” → click “Clear data”. This frees storage and removes corrupted cache files.

Fix 4: Check Storage Space

Chromebooks with low storage (under 10% free) run noticeably slower. Go to Settings → Device → Storage Management. Common culprits: downloaded files, offline Google Docs files, Android app data. Delete files you don’t need or move them to Google Drive.

Fix 5: Restart Your Chromebook (Properly)

Chromebooks often stay in sleep mode for days without a full restart. A full restart (not just closing the lid) clears RAM, restarts system processes, and applies pending updates. Click the clock → Power button → Restart (not Shut Down then Power On — that’s slower).

Fix 6: Check for and Install Updates

A pending ChromeOS update can cause slowness while the system waits to install it. Go to Settings → About ChromeOS → Check for Updates. Install any available updates and restart. Keeping ChromeOS current also patches security vulnerabilities that can cause performance issues.

Fix 7: Disable or Limit Android Apps

Android apps on Chromebook run inside a virtual machine and are significantly more resource-intensive than web apps. If you have Android apps installed you rarely use, uninstall them. Go to Settings → Apps → Google Play Store → Manage Android Preferences → see installed apps.

Fix 8: Turn Off Linux (Beta) If You Don’t Use It

The Linux development environment (Crostini) uses substantial RAM even when idle. If you enabled it but don’t use it regularly, go to Settings → Developers → Linux development environment → Turn Off. This reclaims significant memory.

Fix 9: Reset Chrome Flags to Default

Experimental Chrome flags (chrome://flags) can cause instability and slowness. If you’ve ever enabled experimental features, reset them: go to chrome://flags → click Reset all button at the top → restart. This reverts any problematic experimental settings.

Fix 10: Powerwash (Factory Reset) as a Last Resort

If nothing else works, a Powerwash (factory reset) gives you a clean Chromebook. It deletes everything stored locally but your Google Account data (Drive, bookmarks, settings) syncs back automatically. Go to Settings → Advanced → Reset Settings → Powerwash → Restart. The Chromebook returns to out-of-box speed.
