Troubleshooting Common Laptop Issues: A DIY Guide

5 February 2026

Laptops are an essential part of our daily lives, whether for work, study, or entertainment. But like any piece of technology, they can run into problems. Before you panic or rush to a technician, try troubleshooting—many issues have simple DIY fixes.

This guide will walk you through common laptop problems and how to resolve them, saving you time and money.

1. Laptop Won’t Turn On

Nothing is more frustrating than pressing the power button and getting no response. Here’s what you can do:

Check the Power Supply

- Ensure the charger is plugged into both the laptop and the wall outlet.
- Test the outlet with another device to confirm it’s working.
- Try a different charger if available—your current one might be faulty.

Remove External Devices

- Sometimes, peripherals like USB drives or external hard disks can prevent booting.
- Unplug everything and try turning the laptop on again.

Perform a Hard Reset

- If the battery is removable, take it out, hold the power button down for 30 seconds, then reinsert the battery and try again.
- If the battery is internal, press and hold the power button for about 60 seconds and then try turning it on.

If none of these work, the issue could be with the motherboard, power jack, or battery, requiring professional help.

2. Slow Performance

If your laptop takes forever to load, it might be time for some cleanup.

Check for Background Processes

- Press `Ctrl + Shift + Esc` to open Task Manager.
- Look for programs using high CPU or memory and close unnecessary ones.

Disable Startup Programs

- Open Task Manager, go to the Startup tab, and disable unwanted programs from launching at boot.

Increase Virtual Memory

- Go to Control Panel > System > Advanced system settings > Performance settings > Advanced tab.
- Under Virtual Memory, increase the size for better performance.

Upgrade RAM or Storage

- If your laptop has low RAM (4GB or less), upgrading to at least 8GB can significantly improve speed.
- Replacing an old HDD with an SSD can make a world of difference.

3. Overheating and Noisy Fan

A hot laptop can slow down performance and even shut down unexpectedly.

Clean the Vents and Fan

- Dust buildup is a major cause of overheating.
- Use compressed air to blow out dust from the vents.

Use a Cooling Pad

- A cooling pad can provide additional airflow to prevent overheating.

Check for High CPU Usage

- If a program is hogging resources, it could cause excessive heat.
- Open Task Manager and close unnecessary processes.

Update BIOS and Drivers

- Sometimes, outdated firmware can lead to poor heat management.
- Check the manufacturer’s website for BIOS and driver updates.

4. Battery Draining Too Fast

If your battery dies quicker than expected, try these fixes.

Adjust Power Settings

- Go to Control Panel > Power Options and select Power Saver mode to extend battery life.

Reduce Screen Brightness

- Lowering brightness can significantly impact battery longevity.

Turn Off Unnecessary Background Apps

- Open Task Manager and close apps running in the background.

Unplug Peripherals

- USB devices, external hard drives, and even a wireless mouse can drain battery life.

Check Battery Health

- On Windows, open Command Prompt and type:

  powercfg /batteryreport
  

- This generates a report showing battery health and estimated lifespan.
- If your battery health is poor, consider replacing it.

5. Wi-Fi Connectivity Issues

Laptop not connecting to Wi-Fi? Here are some troubleshooting steps.

Restart the Router and Laptop

- Sometimes, a simple restart resolves connectivity issues.

Forget and Reconnect to the Network

Run Windows Troubleshooter

- Go to Settings > Update & Security > Troubleshoot > Internet Connections and run the troubleshooter.

Check Airplane Mode

- Ensure that Airplane Mode is turned off, as it disables all network connections.

6. Laptop Freezing or Crashing

A freezing laptop can be seriously annoying, but there are ways to fix it.

Check for Software Conflicts

- If the issue started after installing a program, try uninstalling it.

Run a Virus Scan

- Malware can slow down or crash your system. Use Windows Defender or a trusted antivirus program.

Update Windows and Drivers

- Keeping your system updated reduces crashes caused by outdated software.

Perform a System Restore

- If issues started recently, restore your laptop to an earlier point where it was functioning well.

7. Keyboard or Touchpad Not Working

If your keyboard or touchpad stops responding, don’t worry.

Restart Your Laptop

- A simple restart can fix unresponsive inputs.

Check for Dirt and Debris

- Use compressed air to remove dust from the keyboard.

Enable Touchpad

- If the touchpad isn’t working, it might be disabled.
- Press `Fn + F7` (or a similar key combination) to toggle the touchpad.

Update or Reinstall Drivers

- Open Device Manager > Keyboards (or Mice and other pointing devices) and update the driver.

If your keyboard or touchpad is physically damaged, you may need to replace them.

8. Blue Screen of Death (BSOD)

Seeing the Blue Screen of Death can be terrifying, but it’s usually fixable.

Note the Error Code

- The error code on the BSOD screen can provide clues on what’s wrong.

Remove Recently Installed Software or Hardware

- A new driver or hardware might be causing conflicts.

Check for Corrupt System Files

- Open Command Prompt (Admin) and run:

  sfc /scannow
  

- This scans and repairs corrupt system files.

Update Drivers

- Outdated or corrupt drivers often cause BSODs, so update all essential drivers.

Run a Memory Check

- Faulty RAM can trigger BSOD.
- Open Windows Memory Diagnostic and let it scan for issues.
