The Real Reasons Behind a Slow Laptop – And How to Fix Them
We’ve all been there. You open your laptop running slow, wait… and wait… until you feel like throwing it across the room. As someone who’s repaired hundreds of laptops at iRepair Mobiles Reading, I can tell you—most of these slowdowns are easy to fix if you know what to look for.
1. Identify Resource-Heavy Programs First
When your laptop running slow, chances are, it’s because of resource-heavy programs hogging the CPU, memory, or disk. You can open the Task Manager by pressing Ctrl, Alt, Delete, then clicking the Processes tab to see which apps are taking up most of the processing power. You’ll notice some programs sitting idle, yet still using up memory power.
Once you spot them, you can reallocate resources or permanently remove them if unnecessary. This simple step can go a long way in speeding up your old laptop and improving its performance.
2. Prevent Unwanted Start-Up Programs
Too many start-up programs slow down your boot up time. These apps run in the background automatically every time you turn your laptop on. To manage this, go to Task Manager, click the Startup tab, and Disable anything that isn’t essential. This leads to a faster start-up time and freed up resources for the tasks you actually need.
3. Uninstall Unused Programs
Your system may be clogged with programs, apps, or even pre-installed software you don’t use. These take up disk space and slow down your machine. Go to Control Panel > Programs and Features, and hit Uninstall on any software that’s not necessary to run your tasks. Deleting them helps free up disk space and gives your laptop breathing room.
4. Check Your Storage Capacity
Your storage situation directly affects your laptop’s speed and performance. A full hard disk drive (HDD) slows down your processor, especially when trying to retrieve file data. Consider upgrading to a solid state drive (SSD) for better speed up results. SSDs are built with flash memory, have no moving parts, and help with everyday tasks like file loading and app launching.
To check your current storage capacity, press the Windows button > Settings > System > Storage. You’ll see your free space and file types. If you’re close to maxing out, consider installing a new SATA SSD or NVMe SSD, both of which improve speed and battery power while being more durable.
5. Use an External Drive
For those who are regularly on the go, using an external drive is a smart way to expand storage. Devices like Crucial X10 Pro or Crucial X9 Pro come in 1TB, 2TB, and 4TB options with speeds up to 2100 MB/s, ideal for video editing and large file transfers. They connect via USB cable or Thunderbolt, and offer fast, plug-and-play storage for both Windows and MacBooks.
Whether it’s for backups, games, or heavy files, these budget-friendly options provide a big performance lift without opening your laptop.
6. Do You Need More RAM?
Not enough RAM means your system’s performance suffers. If your laptop struggles even with simplest tasks, it’s time to upgrade. Open Task Manager > Performance tab > Memory window to see if you’re maxing out usage. Upgrading RAM (e.g., DDR3, DDR4, DDR5) leads to increased responsiveness, smoother multitasking, and better overall performance improvements.
Use tools like Crucial System Scanner to find compatible RAM for your device and follow their 10 quick steps for a safe upgrade.
7. Clean Up Your Disk
A cluttered system can slow you down. Start cleaning your disk by deleting temporary files, Recycle Bin junk, and other data that can be safely deleted. Search for Disk Clean up in the Windows taskbar, open the app, select your C: drive, and check Files to delete based on your preference. It helps your computer find files quickly and stay organized.
8. Defragment Your Hard Drive
If you still use an HDD, it’s important to defragment it occasionally. Data gets stored in fragments, which increases time to access information. Defragging rearranges these files into a more logical formation, making your system run quicker. Note: this is not necessary for SSDs.
9. Optimize Your Web Browser
Sometimes, your laptop running slowly might just be due to your web browser. Make sure you’re using the most recent version, and install new versions automatically. Go into the browser’s menu, look for About, and ensure you’ve enabled add-ons and extensions that are necessary only. Delete the rest to reduce slow web browsing.
10. Don’t Forget the Dust!
Dust build up is often overlooked but a serious performance killer. It blocks your fan, causing your laptop to overheat, which in turn reduces performance. Every month, take time to gently clean the dust using compressed air, especially around the keyboard, case, and fan vents. Use short bursts to avoid damaging components.
11. Restart Your Laptop Often
Leaving your laptop on 24/7 may seem convenient, but it eats up memory resources. A simple restarting computer process helps clear memory cache, close running programs, and apply system updates. Go to Start menu > Power > Restart for a clean, fresh start.
Conclusion
A laptop running slow is frustrating, especially when you’re stuck waiting for every task. But fixing it doesn’t require monumental changes—just a few smart, small manageable fixes. From managing start-up programs to RAM upgrades and cleaning your disk, these steps offer immediate lasting results.
If you’ve tried everything and still feel stuck, it might be time to speak to a technician or, as a last resort, considering replacement. At iRepair Mobiles Reading, we’ve helped thousands bring their laptops back to life. Stop by, and let’s fix that slow machine together!
