A slow laptop doesn’t always mean it’s time for a new one. In most cases, a few simple changes can dramatically improve performance — often within minutes. Before you spend hundreds on a replacement, try these 10 proven fixes.
1. Restart Your Laptop Regularly
Restarting clears temporary files, applies pending updates, and frees up RAM that background processes have been hoarding. A full restart is always the first step when a laptop feels sluggish.
2. Disable Startup Programs
Many apps launch automatically when your laptop starts, consuming memory immediately. On Windows, press Ctrl + Shift + Esc, click the Startup tab, and disable anything unnecessary. On Mac, go to System Settings → General → Login Items.
3. Free Up Storage Space
When your hard drive is more than 80% full, performance drops significantly. Delete files you no longer need, empty your Recycle Bin, and move photos and videos to an external drive or cloud storage. Keep at least 15–20% of your drive free.
4. Run a Malware Scan
Malware and adware silently consume CPU and memory. Run a full scan with Windows Defender or Malwarebytes. If your laptop started slowing down suddenly, this is one of the first things to check.
5. Update Your Operating System and Drivers
Outdated software creates compatibility issues and performance bugs. Ensure Windows or macOS is up to date, and check that your graphics and network drivers are current.
6. Adjust Your Power Settings
If your laptop is set to Power Saver mode, it deliberately throttles performance. Switch to Balanced or High Performance when plugged in. On Windows: Settings → System → Power & Sleep → Additional Power Settings.
7. Clean Up Your Browser
Too many open tabs, extensions, and cached data make browsing sluggish. Close unused tabs, disable unnecessary extensions, and clear your cache regularly.
8. Upgrade to an SSD
If your laptop still has a traditional spinning hard disk drive, upgrading to a solid-state drive (SSD) is the single most impactful hardware upgrade you can make. SSDs are typically 5–10x faster. A 500GB SSD can cost as little as £40–£60.
9. Add More RAM
If you frequently run multiple applications, your laptop may be running low on RAM. 8GB is the practical minimum in 2026; 16GB is comfortable for most users.
10. Reinstall Your Operating System
A clean reinstall of Windows or macOS can breathe new life into a slow laptop. Back up your files first, then use Windows’ Reset this PC option or macOS’s Recovery Mode reinstall.
Frequently Asked Questions
How do I know if my laptop needs hardware or just a software fix?
Start with software fixes. If still slow, check CPU and RAM usage in Task Manager while idle. High usage with nothing open suggests a hardware limitation or malware.
Will upgrading RAM make my laptop faster?
Yes, if RAM shortage is the bottleneck. If you regularly see 90%+ RAM usage, more RAM will help significantly.
Is it worth fixing a 5-year-old laptop?
Generally yes, especially if an SSD upgrade can extend its life by 2–3 years at a fraction of replacement cost.
Can too many browser tabs slow down my whole laptop?
Absolutely. Each Chrome tab consumes RAM — 20+ tabs can easily use 4–6GB, leaving little for anything else.
How often should I defragment my hard drive?
Only traditional HDDs benefit from defragmentation. Never defragment an SSD — it shortens the drive’s lifespan without any performance benefit.
