Why laptops slow down
Common causes include too many startup programs, a full drive, outdated software, overheating and malware. Older laptops with hard drives (HDD) and 4GB of RAM also struggle with modern apps. Most of these problems are easy to fix.
How to speed up a slow laptop: 12 fixes that work
1. Restart properly
Restarting clears memory and finishes pending updates. Many people only close the lid for weeks, which lets problems build up.
2. Disable startup programs
Press Ctrl + Shift + Esc to open Task Manager. Open the Startup apps tab and disable programs you don’t need at boot.
3. Free up disk space
Open Settings › System › Storage and turn on Storage Sense. Delete temporary files, old downloads and apps you no longer use. Keep at least 15% of the drive free.
4. Uninstall unused programs
Go to Settings › Apps › Installed apps. Remove trial software, old games and toolbars.
5. Update Windows and drivers
Open Settings › Windows Update and install all updates. Updated drivers, especially graphics drivers, improve speed and stability. Microsoft explains more in its official performance tips.
6. Scan for malware
Run a full scan with Windows Security. Malware often runs hidden in the background and slows everything down.
7. Change the power mode
Open Settings › System › Power & battery. Set Power mode to Best performance when plugged in.
8. Reduce visual effects
Search for “Adjust the appearance and performance of Windows”. Choose Adjust for best performance, then re-enable smooth fonts if text looks rough.
9. Limit browser tabs and extensions
Browsers use lots of memory. Close unused tabs and remove extensions you don’t need. Turn on Memory Saver in Chrome or Sleeping Tabs in Edge.
10. Clean the vents and keep it cool
Dust blocks airflow and causes overheating. When laptops overheat, they slow down to protect themselves. Use the laptop on a hard surface, not a bed or pillow.
11. Upgrade to an SSD
If your laptop still uses a hard drive, an SSD is the single biggest upgrade. Boot times often drop from minutes to seconds.
12. Add more RAM
8GB of RAM is the minimum for smooth Windows 11 use; 16GB is better. Check whether your laptop has a free RAM slot.
Check what is slowing it down
Task Manager shows exactly what uses your laptop’s resources. Open it with Ctrl + Shift + Esc and click the CPU, Memory and Disk columns to sort them.
- CPU near 100%: a program or update is working hard. End tasks you don’t recognise only after searching their names.
- Memory near 100%: close tabs and apps, or consider more RAM.
- Disk near 100%: common with old hard drives. An SSD upgrade usually solves it.
Reset Windows as a last resort
If nothing helps, reset Windows. Go to Settings › System › Recovery › Reset this PC. Choose Keep my files to remove apps and settings but keep documents. Back up everything first, just in case. A fresh install often makes an old laptop feel new again.
When a slow laptop needs replacing
If your laptop is very old, can’t be upgraded, or still lags after these fixes, it may be time for a new one. For work and study, see the Honor MagicBook Pro 14 (2026) or the Surface Laptop 8. For games, read our gaming laptop buying guide.
Protect your laptop from power problems
Sudden power cuts and surges can corrupt files and damage hardware. Use a surge protector, and consider clean backup power. Our guide to the best inverter generators in Nigeria explains your options.
Frequently asked questions
What is the fastest way to speed up a slow laptop?
Restart it, disable startup apps and free up disk space. These three steps help most laptops immediately.
Does an SSD make a laptop faster?
Yes. Replacing a hard drive with an SSD is usually the biggest speed improvement for older laptops.
How much RAM do I need for Windows 11?
At least 8GB for smooth everyday use, and 16GB for heavy multitasking.
How often should I restart my laptop?
Once a day is ideal, and at least a few times a week. Restarting clears memory, finishes updates and stops small problems from building up over time.
