Hp Laptop Not Turning On Caps Lock Blinking: How to Fix?

Having an HP laptop that won’t turn on with the caps lock blinking away can be seriously frustrating. This is a common issue, often signaling some form of internal hardware failure or power connection problem.

Our article will provide simple yet effective fixes for this nerve-racking situation. Let’s dive in and make your HP laptop work as smoothly as ever!

Reasons Behind the HP Laptop Caps Lock Blinking Issue

The HP Laptop Caps Lock blinking issue can occur due to internal failures, CPU issues, power connection problems, or BIOS errors.

Internal failure

The internal failure of an HP laptop often manifests as a blinking Caps Lock key. This could be due to various reasons such as overheating, dust accumulation in the hardware, or even faulty components within the device.

Situations like these can prevent your laptop from turning on properly. Regular cleaning and servicing help mitigate this issue, ensuring the smooth functioning of the laptop’s internal elements.

Some instances may require the replacement of defective parts to rectify the problem entirely.

CPU issue

CPU failure is a major reason behind the HP laptop caps lock blinking issue. The central processing unit (CPU), often referred to as the brain of the computer, carries out most of the processes.

If it encounters problems, you may experience complications like your HP laptop not turning on and the caps lock key blinking continuously.

A common sign of CPU trouble is when the “Caps Lock” LED light blinks in a specific pattern. This usually involves one long blink followed by two shorter ones. In such cases, your screen remains black or unresponsive due to this critical component’s malfunctioning.

Power connection problem

A faulty power connection often results in your HP laptop not turning on while the Caps Lock keeps blinking. Power issues can stem from a drained battery, improper plugging of the charger, damaged power cord, or even malfunctions at the socket where you plug your charger.

A defective AC adapter can also trigger this problem; it might fail to charge the laptop effectively, leading to caps lock blinks as a warning sign of inadequate power supply. It’s crucial then to ensure your charging cable and adapter are working well; try using different outlets or another compatible charger if necessary.

Regularly check for any visible damage on these components and replace them promptly if need be.

BIOS error

The BIOS error can also cause the caps to lock on an HP laptop to blink. This error occurs when there is a problem with the Basic Input/Output System (BIOS) software that controls your computer’s hardware.

When the BIOS encounters an issue, it may display a black screen or fail to start up properly. Resolving this error requires resetting the laptop’s BIOS settings or updating the BIOS firmware to fix any bugs or glitches that may be causing the blinking caps lock issue.

Solutions to Fix HP Laptop Caps Lock Blinking Issue

To fix the HP laptop caps lock blinking issue, you can clean air vents and hardware, perform a hard reset, reset the laptop’s BIOS, check power connections, and reinstall the hardware.

Read on for detailed steps to resolve this problem.

Clean air vents and hardware

To fix the issue of an HP laptop not turning on with the caps lock blinking, it is important to clean the air vents and hardware. Dust and debris can accumulate over time, which can obstruct the airflow and cause overheating.

This can lead to various issues, including the laptop not powering on properly. By cleaning the air vents using compressed air or a soft brush, you can remove any buildup that might be hindering proper ventilation.

Additionally, it is recommended to clean other hardware components such as the fan and heat sink to ensure optimal performance and prevent further issues in the future.

By regularly maintaining and cleaning your laptop’s air vents and hardware, you can improve its overall performance and avoid problems like black screens or blinking caps lock lights.

Perform a hard reset

Performing a hard reset can often resolve the issue of an HP laptop not turning on with a blinking caps lock. To do this, start by disconnecting the laptop from any power sources and removing the battery if possible.

Then, press and hold down the power button for around 15 seconds to drain any residual power. After that, plug in the charger or put the battery back in and try powering on the laptop again.

A hard reset helps in resetting any temporary software glitches that might be causing the problem, allowing you to potentially fix the issue without further troubleshooting steps.

Reset the laptop’s BIOS

To fix the blinking caps lock issue on your HP laptop, you can try resetting the laptop’s BIOS. This can help resolve any errors or conflicts in the system settings that might be causing the problem.

To do this, you’ll need to access the BIOS menu by pressing a specific key during startup. Once in the BIOS menu, you can choose to reset it to its default settings or update it if there is an available update.

Resetting the BIOS can often solve issues related to hardware and software configuration, allowing your laptop to start up properly again.

Check power connections

To troubleshoot the HP laptop caps lock blinking issue, it is important to check the power connections. Make sure that the power adapter is properly plugged into both the wall outlet and the laptop.

Also, ensure that there are no loose connections or damaged cables. In addition, try using a different power adapter or charging cable to rule out any issues with those components.

By checking and ensuring proper power connections, you can eliminate any potential power-related problems as the cause of the caps lock blinking issue on your HP laptop.

Reinstall hardware

To fix the caps lock blinking issue on your HP laptop, one possible solution is to reinstall the hardware. Sometimes, faulty or loose hardware connections can prevent your laptop from turning on properly.

By carefully removing and reattaching components such as RAM modules and hard drives, you can ensure that everything is securely in place. This simple act of reinstalling the hardware may resolve any connection-related issues and help your laptop start up normally again.

It’s important to handle the hardware with care and follow proper procedures to avoid damaging any components during the process.

In addition to checking for loose connections, you can also consider cleaning the connectors before reinstalling them. Dust or debris buildup can interfere with proper contact between components, leading to startup problems.


To conclude, if you’re experiencing the issue of your HP laptop not turning on with a blinking caps lock, there are several possible reasons and solutions to consider. Internal failures, CPU issues, power connection problems, and BIOS errors could be the culprits behind this problem.

However, by cleaning air vents and hardware, performing a hard reset, resetting the laptop’s BIOS, checking power connections, or reinstalling hardware, you may be able to resolve the blinking caps lock issue and get your laptop up and running again.
