Two Simple Methods to Check Laptop Temperature

For those who often work on laptops, it's easy to dismiss the heat buildup during prolonged use as normal. However, in reality, abnormal laptop temperatures could indicate underlying issues. With the following two methods, you can accurately check your laptop's temperature to quickly diagnose its condition and take it for timely maintenance.

What Causes Laptop Overheating? 

The most common reason for laptop overheating is continuous operation for extended periods, causing the CPU to run constantly. Additionally, other factors such as malfunctioning cooling components, excessive dust buildup, high ambient temperatures, poor CPU quality, etc., can also contribute.

Risks of Excessive Laptop Heat 

When your laptop's temperature rises, you'll often encounter issues such as lagging, freezing, sudden shutdowns, or even it going into a 'hibernation' state from which it cannot wake up.

If you notice unusual heat, slowdowns, or lags, it's time to give your laptop a break and take it to a service center for early diagnosis.

Check Computer Temperature via BIOS (or UEFI) 

Every laptop comes with a BIOS, and newer models have upgraded to UEFI, which controls basic functions of the machine. Using BIOS, you can accurately determine your laptop's temperature. Here's how to access BIOS:

Restart your machine. When you see the manufacturer's logo, quickly press the designated function keys to access BIOS. These keys could be F2, F10, F12, Del, etc.

Some common BIOS activation keys for different brands:

Acer: F2 or DEL

ASUS: F2 or Del

Dell, HP, Lenovo: F2 or Fn + F2

Lenovo Desktops: F1

Lenovo ThinkPads: Press Enter + F1.

MSI: DEL

Microsoft Surface Tablets: Press and hold the volume up button

Samsung, Sony: F1, F2, or F3

Toshiba: F2

After entering BIOS, navigate to the “Power” section. The “CPU Temperature” line will show you the current temperature of your CPU. For UEFI systems, you'll find the CPU temperature under the “Temperature” section.

Conclusion

With just a few simple steps, you can check your laptop's temperature. However, these are basic temperature checks. If you notice your laptop behaving abnormally due to high temperatures frequently, promptly take it to reputable maintenance centers for thorough inspection and timely repairs.
