Laptop speed depends mostly on the processor, the amount of RAM, the type of storage, and how well the laptop stays cool. A laptop usually slows down because too many apps run at startup, the storage drive is nearly full, updates are missing, or dust is trapping heat. Most slow laptops speed up with a few simple fixes, and older laptops often get a big boost from an SSD or more RAM.
In this laptop speed glossary, we explain what affects laptop performance, how to speed up a slow or old laptop, why laptop fans get loud, and what FPS means for gaming. For more laptop terms, visit our laptop glossary.
What Affects Laptop Speed?
Laptop speed comes from a combination of hardware and conditions. The processor, RAM, and storage set how fast a laptop can be, while heat, power settings, background apps, and software health decide how fast it actually feels day to day. A powerful laptop can still feel slow if it’s overheating or its storage is full.
Hardware that affects laptop speed
| Part | How it affects speed | Learn more |
|---|---|---|
| Processor (CPU) | Runs apps and the operating system; more cores and newer generations handle more at once | Processors |
| RAM | Holds open apps and tabs; too little RAM causes slowdowns when multitasking | Memory and storage |
| Storage | SSDs load apps and start Windows much faster than hard drives or eMMC | Storage types |
| Graphics (GPU) | Draws games, video, and 3D; affects frame rates and editing speed | Graphics cards |
| Cooling | Keeps the processor from slowing down to protect itself from heat | Cooling |
Conditions that slow a laptop down
- Too many startup apps: Programs that launch automatically use memory and processor time from the moment you sign in
- A nearly full drive: Windows needs free space to run smoothly; aim to keep at least 10% to 15% of the drive free
- Missing updates: Older drivers and software can cause bugs and slowdowns
- Overheating: Dust in the vents or a soft surface under the laptop traps heat and triggers thermal throttling
- Power-saving mode: Battery-saving settings reduce performance to extend run time
- Malware: Unwanted software can use system resources in the background
- Aging battery: A worn battery may limit performance when the laptop is unplugged
To see what’s slowing your laptop, open Task Manager with Ctrl + Shift + Esc and check which apps are using the most CPU, memory, and disk. Our guide on how to check PC specs shows how to read your laptop’s hardware details.
How to Speed Up a Slow Laptop
To speed up a slow laptop, restart it, install updates, turn off unneeded startup apps, free up storage space, and switch to a higher-performance power mode. Then clean the vents and scan for malware. If your laptop is still slow, adding RAM or replacing an old hard drive with an SSD can make a big difference.
Step-by-step: speed up a slow Windows laptop
- Restart the laptop. A restart clears temporary files and closes stuck background processes.
- Install updates. Go to Settings > Windows Update and install all updates, then update HP drivers and BIOS through the HP app or HP Support Assistant.
- Turn off startup apps. Open Task Manager, select Startup apps, and disable programs you don’t need right away.
- Free up storage. Go to Settings > System > Storage, turn on Storage Sense, and remove apps and files you no longer use.
- Change the power mode. Go to Settings > System > Power & battery and choose Best performance when you’re plugged in.
- Scan for malware. Run a full scan with Windows Security or your security software.
- Clean the vents. Clear dust from fans and vents so the laptop stays cool; see our cleaning and care glossary.
- Close extra browser tabs. Each open tab uses memory, especially video and web apps.
How to speed up an old laptop
| Option | What it does | Best for |
|---|---|---|
| Replace a hard drive with an SSD | Cuts startup and app load times dramatically | Older laptops with spinning hard drives |
| Add more RAM | Lets you run more apps and tabs without slowdowns | Laptops with removable memory slots and 8GB or less |
| Reset Windows | Removes built-up clutter and returns the laptop to a clean state | Laptops that have slowed down over years of use |
| Replace the battery | Restores full performance on battery power | Laptops with worn batteries |
| Use lighter apps | Reduces the load on older processors | Laptops with older, slower processors |
Before upgrading or resetting, back up your files. Learn more in our laptop installations and upgrades glossary, our backups, troubleshooting, and resets glossary, and our article on how to upgrade your laptop. If your laptop is too old to support current updates, it may be time for a new one; see our laptop picking and setup guide.
Laptop Fan Speed
Laptop fans speed up automatically when the processor or graphics card gets hot, so some fan noise during demanding tasks is normal. Fans that run loudly all the time, even during light use, usually mean the laptop is working harder than it should because of dust, blocked vents, background apps, or a high-performance power mode.
Why is my laptop fan so loud?
| Cause | What to do |
|---|---|
| Demanding apps, games, or video exports | Normal; fans should quiet down when the task ends |
| Dust in the vents | Clean the vents with short bursts of compressed air while the laptop is off |
| Blocked airflow | Use the laptop on a hard, flat surface, not a bed, couch, or lap |
| Background apps | Check Task Manager for apps using a lot of CPU and close or disable them |
| Performance power mode | Switch to Balanced or a quiet mode when you don’t need full speed |
| Warm room | Move to a cooler spot or use a stand or cooling pad |
| Outdated BIOS or drivers | Install the latest HP BIOS and driver updates, which can improve fan control |
How to control laptop fan speed
Most laptops manage fan speed automatically, and that’s usually the safest setting. You can influence it by changing the power or performance mode in Windows Settings or in HP’s software on supported models, which often includes quiet, balanced, and performance options. Some HP laptops also offer a BIOS setting that keeps the fan running at all times for more consistent cooling. Avoid third-party tools that force fans to run slower, because they can let the laptop overheat.
If the fan makes grinding or clicking sounds, or the laptop shuts down from heat, it may need service. Learn more in our cooling glossary and our creative and technical laptops glossary, which covers performance modes and cooling pads.
FPS on a Laptop
FPS (frames per second) is the number of images a laptop draws on screen each second in a game or animation. Higher FPS looks smoother and feels more responsive. Most games feel smooth at 60 FPS, while competitive players aim for 120 FPS or more on a high refresh rate display. FPS depends mostly on the graphics card, but the processor, RAM, cooling, and game settings matter too.
What affects FPS on a laptop
| Factor | How it affects FPS |
|---|---|
| Graphics card (GPU) | The biggest factor; a dedicated GPU delivers much higher FPS than integrated graphics |
| Game settings | Higher resolution, textures, shadows, and ray tracing lower FPS |
| Processor (CPU) | Matters most in fast-paced and strategy games with many objects on screen |
| RAM | Too little RAM causes stutters; 16GB is the standard for gaming |
| Heat | Thermal throttling lowers FPS during long sessions |
| Power | Laptops usually limit GPU power on battery, which lowers FPS |
How to improve FPS on a laptop
- Plug in the charger. Laptops deliver full GPU performance only on AC power.
- Use the dedicated GPU. On laptops with two GPUs, set games to use the high-performance GPU in Settings > System > Display > Graphics.
- Choose a performance mode. Switch to Best performance in Windows or a gaming mode in HP’s software.
- Update graphics drivers. New drivers often improve performance in recent games.
- Lower demanding settings. Reduce shadows, resolution, or ray tracing, or turn on upscaling such as NVIDIA DLSS or AMD FSR.
- Close background apps. Browser tabs, downloads, and streaming apps take resources from the game.
- Keep it cool. Clean the vents and play on a hard surface or cooling pad.
To see your FPS, turn on the Game Bar performance overlay by pressing the Windows key + G. Learn more in our gaming laptops glossary and gaming performance glossary, and see how refresh rate works in our refresh rate and response time glossary.
Laptop Speed FAQs
Why is my laptop so slow?
A laptop is usually slow because too many apps run at startup, the storage drive is nearly full, updates are missing, or dust is causing the laptop to overheat. Older laptops with hard drives or 4GB to 8GB of RAM also slow down with modern apps.
How can I make my laptop faster?
To make a laptop faster, restart it, install all updates, disable unneeded startup apps, free up storage space, and switch to a higher-performance power mode. Upgrading to an SSD or adding RAM gives older laptops the biggest speed boost.
Does more RAM make a laptop faster?
More RAM makes a laptop faster when it runs many apps, browser tabs, or large files at once. Adding RAM won’t noticeably speed up a laptop that already has enough for its workload.
Is it normal for a laptop fan to be loud?
It is normal for a laptop fan to get louder during gaming, video editing, or other demanding tasks. A fan that stays loud during light use often means dust, blocked vents, or background apps are making the laptop work too hard.
How do I lower my laptop fan speed?
To lower laptop fan speed, clean the vents, use the laptop on a hard surface, close demanding background apps, and switch to a balanced or quiet power mode. Avoid tools that force fans to slow down, because they can cause overheating.
What is a good FPS for a laptop?
60 FPS is a good frame rate for most laptop games and feels smooth. Competitive gamers often aim for 120 FPS or more on a high refresh rate display.
Why is my laptop FPS low?
Low FPS on a laptop usually comes from running on battery, using integrated graphics instead of the dedicated GPU, outdated drivers, game settings that are too high, or overheating. Plugging in and lowering demanding settings often helps right away.
Does an SSD make a laptop faster?
Yes, an SSD makes a laptop much faster than a hard drive, especially at startup, when opening apps, and when loading files. Replacing a hard drive with an SSD is one of the most effective upgrades for an older laptop.
