Slow Laptop? 10 Fixes That Actually Speed It Up

A laptop that takes forever to start, freezes when you open a browser tab, or sounds like a jet engine is frustrating. The good news is that slowness usually has a few common causes, and most of them are free to fix.

Work through these steps in order. They go from the quickest wins to the bigger changes, and they apply to both Windows laptops and MacBooks unless noted.

Quick wins (10 minutes)

1. Restart properly. Many people only close the lid for weeks. A full restart clears memory, finishes updates and stops stuck background processes.
2. Close what you're not using. Every open app and browser tab uses memory. Twenty tabs can slow down even a fast machine.
3. Check what's hogging resources. On Windows press Ctrl + Shift + Esc to open Task Manager. On a Mac open Activity Monitor. Sort by CPU or memory to find the culprit.

Clean up startup and storage

Many programs set themselves to launch every time your laptop turns on. Over time, that list grows and startup slows to a crawl.

4. Disable startup apps. On Windows go to Task Manager → Startup apps and disable anything you don't need instantly. On a Mac go to System Settings → General → Login Items.
5. Free up disk space. When your drive is nearly full, everything slows down. Aim to keep at least 15–20% free. Delete old downloads, empty the trash and move large photo or video folders to cloud or external storage.
6. Uninstall what you never use. Old trial software and games often run background services you never see.

Update and scan

Updates are not only about new features. They frequently include performance fixes and security patches.

7. Install system updates. Run Windows Update or macOS Software Update, then restart.
8. Run a malware scan. On Windows, the built-in Windows Security scan is a good start. Unexpected pop-ups, a new browser homepage or constant high CPU use are warning signs.

Check heat and hardware

Laptops slow themselves down when they get too hot to protect their parts. Using a laptop on a bed or sofa can block the air vents.

9. Keep it cool. Use it on a hard, flat surface and gently clean dusty vents with compressed air.
10. Consider a simple upgrade. If your laptop still has an old spinning hard drive, switching to an SSD is the single biggest speed boost you can buy. Adding more RAM also helps if you often run out of memory — check whether your model supports upgrades first.

When it's time for a new laptop

If your laptop no longer receives system updates, the battery barely lasts, and it is still slow after every step above, a replacement may make more sense than repairs.

Before you shop, back up your files and note which apps you really use. That tells you exactly how much power you need — and stops you paying for more than you will ever use.
