Lenovo Laptop Running Slow or Freezing? Here's Why and How to Speed it Up
Last update: April 26, 2017 | by Justin Hawks
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 start to change. You notice your Lenovo begins 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 run slowly and what you can do 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 Lenovo PCs over the past ten years.
1. You have too many programs running at once (especially on startup)
The brain of a computer (CPU, memory, etc.) is like that of a human. Handling multiple things at once will make you inefficient — that's why I don't believe in multitasking! The symptoms of having 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 disabling applications that automatically start every time your Lenovo boots. If you are using a new laptop that's bundled with pre-installed programs, uninstall them. To save time, you can do so in CleanMyPC (via the "Complete Uninstall" feature)
Next, check what tasks are running in the background and how much system resources they are using. You can have a clear overview through "Task Manager". Knock out those heavy processes that you don't currently need. Note that many times it's security software that is over-consuming system resources. Make sure you are use a good 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 Lenovo laptop acts up: everything lags seriously, you are unable to shut down the system, web browsers are 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) has the functionality, but the program is not that powerful; I find Plumbytes Anti-Malware a greater option and it's much easier to use. Keep in mind that you'd 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 and eliminate freezing issues based on my personal experience. Also, Windows generally alerts you of "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. You can start transferring big files like pictures, videos as they tend to occupy more disk space; Then uninstall applications you don't often use, especially those heavy programs that could take gigabytes in size.
But, there is an easier way to get this done. CleanMyPC is great tool that can keep your Lenovo clean, and it includes several awesome utilities to remove applications and clean up system junk that they leave behind. you can do all of these with the click of a button.
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 hard trying to cool it down. If, 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 a overheated Lenovo can include: your laptop keeps freezing, system lags badly or even shuts 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, try avoid opening several heavy programs at the same time, because that is 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 refers 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, 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, and latest Windows 10 needs 16GB+ in hard drive (source: Microsoft).
So, if you've tried everything else and your Lenovo is still sluggish, try hardware upgrades. 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 .
A faster PC is better than a slow one. Not only does a fast Lenovo boost your work productivity, but it's also good for your health — yes, recent study also shows that 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. Hope you find this guide useful.
