Lenovo Laptop Running Slow or Freezing? Here's Why and How to Speed it Up

Remember the feeling of a brand new Lenovo laptop? A laptop without slowdowns or frozen issues. Everything was just perfect! It's funny how everyone always thinks the same thing when they have a new PC at hand:

Okay, this time I won't play any games on it. I'll keep it clean and won’t install anything that’s likely to lag its performance!

Over time, things change. You notice your Lenovo starts to act up: taking longer to boot, freezing randomly, etc. And you can’t help but screaming out: why is my Lenovo so slow?

If that happen to you, and you want to fix the issues seriously, then you should take a look at this guide:

Top 5 reasons why a Lenovo computer may slow down and how to speed it up.

There are obviously more causes out there, but I’ll just list the main culprits based on my personal experience using two Lenovos over the past ten years.

1. You have too many programs running at once (especially on startup)

A computer's brain (processor, memory, etc) is like human's as well. Handling multiple things at once will make you inefficient — that's why I don't believe in multitasking! The symptoms of have loads of applications running simultaneously on a Lenovo laptop include:

  • Windows OS takes longer or forever to start up;
  • The software you run becomes unresponsive;
  • The mouse cursor freezes or barely moves;
  • Even worse, the whole system crashes.

Start with managing the startup items by removing or disabling applications that automatically start each time your Lenovo boots. If you are using a new laptop that's bundled with pre-installed programs, uninstall all of them unless you find some of them really useful.

Next, check what tasks are running in the background and how much system resource they are using. You can have a clear overview through "Task Manager". Knock out those heavy processes that you don’t need at the moment. Note that many times it’s the security software that is over-consuming system resources. Make sure you are use a decent one and adjust relevant settings.

2. Virus/malware is slowing you down and causing other problems

It's not news that viruses or malicious software can damage any Windows PC, including bogging down its overall performance. Once you feel your laptop really acts up: everything lags seriously, you are unable to shut down the system, web browsers locked up with flying ads, etc; Most likely they’ve got you.

To check if your Lenovo has been infected, you need to scan your PC immediately with an anti-virus or spyware removal tool. Microsoft Security Essential (now called Windows Defender in Windows 10) equipped with any Windows operating system has functionality, but bad news is that the program is not powerful enough; I find MalwareBytes is a greater solution and it is much easier to use. There are plenty of good ones available, one thing to keep in mind that to update your security software regularly.

3. Your hard disk drive is running out of space

Though it's a myth that emptying disk space will tune up a computer in general, maintaining a good percentage of free space on your Lenovo hard drive helps boost performance quite a bit and eliminate freezing issues based on my personal experience. Also, Windows generally alerts you to "low disk space" if that is the case.

So go ahead and clean your hard drive. Unfortunately it isn't always as easy as it sounds because you can't do so with a magic utility. I'd recommend you start transferring big files like pictures, videos as they tend to occupy more disk space; Then uninstall applications you don't use that often, especially those big programs that take gigabytes in size. Last but least, use CCleaner to clear up web browser junks.

4. Overheating is "burning" everything

When the CPU is running hard to process requests, your Lenovo laptop will start to heat up and the fan will work trying to cool it down. Due to some reasons, for example, the heatsink tubes are filled with dust, or your laptop is exposed to a high-temperature environment, chances are overheating is going to take place. The consequences of overheating can include: your Lenovo keeps freezing, system lags badly or even shut down unexpectedly.

The fixes are simple. First off, get a cooling pad or mat for your Lenovo (cost estimate: $20-30); Also, if the heatsink is stuffed, use a can or air compressor to blow out the machine. In addition, if you can, try avoid opening several heavy programs at the same time, because it's likely to drain the CPU. Once again — less multitasking!

5. Your hardware configuration is either too low or faulty

If you are using an old Lenovo, the reason why it's running super slow is probably that — hardware ages. The hardware I'm talking about here mainly refer to memory (RAM), low-capacity hard disk drive (HDD). Any computer is composed of two parts: software and hardware. While software can be upgraded easily, but hardware can't. Often times, software usually has a clear list of minimum requirements on hardware configuration. For instance, Windows 8 needs at least 4GB RAM in memory to run smoothly.

So, if you've tried everything else and your Lenovo is still sluggish, try upgrade the hardware. The best practices are: adding more RAM, and replace your HDD with an SSD (yes, solid-state drive is faster and quieter). Sure, it costs money but it’s worth it and you'll get real performance boost. Be sure to have a geeky friend nearby when you do the upgrade, and remember to backup your data before you proceed just in case any data loss scenarios.

Conclusion

A faster PC is better than a slow one. Not only does it boost your work productivity, but it’s good for your health — yes, recent study also shows a slow computer affects human health. By understanding why your Lenovo is running slow or freezing, you know where to get started to make things right. Some speed up solutions listed above may work better than others, it's up to you to choose which ones(s) to try. That's all from us.
