Powerless Plugged In: Unraveling the Mystery of HP Laptops That Won’t Turn On

Table of Contents


Picture this: You have an important assignment to complete or a crucial work project to finish within the next few hours. You reach for your trusty HP laptop, only to discover that it won’t turn on even when plugged in. This issue can be frustrating and disruptive, but knowing how to address these problems effectively is essential. In this article, we will explore the possible causes of this issue and discuss troubleshooting steps that one can take to resolve the problem.

Possible Reasons for the Issue

Dead or malfunctioning battery

A laptop’s battery might be dead or malfunctioning, which can result in an HP laptop that won’t turn on even when plugged in. Over time, a laptop’s battery capacity will naturally degrade, preventing it from holding a charge and powering the laptop.

Faulty power adapter

Another possible reason for the problem is a faulty power adapter. If the adapter is damaged or not working correctly, it will not provide sufficient power to the laptop, and the laptop will not turn on.

Damaged power socket or laptop DC port

A damaged power socket or laptop DC port can also contribute to the issue. If either of these components is damaged or obstructed in any way, it may prevent power from being supplied to the laptop.

Corrupt system BIOS

A corrupt system BIOS can also prevent an HP laptop from turning on even when plugged in. If the BIOS (Basic Input Output System) is corrupt, it will not function properly and cause problems in the system boot process.

Hardware issues

Sometimes, specific hardware issues can cause the laptop not to turn on. These issues could include problems with the laptop’s RAM, hard drive, or motherboard.

Troubleshooting Steps

1. Check the battery condition

a. Remove and reinsert the battery

If you suspect that the battery might be the issue, try removing and reinserting it. This process can help reestablish a proper connection for the battery.

b. Attempt charging with another compatible battery

If you have access to another compatible battery, try swapping the batteries to determine if the battery is indeed the cause.

2. Inspect the power adapter

a. Confirm proper connection to the power source

Ensure that the power adapter is connected securely to both the power outlet and the laptop.

b. Use a multimeter to test the adapter’s voltage output

A multimeter can be used to test whether the power adapter is supplying the correct voltage for your laptop.

c. Test the adapter with another compatible device

If possible, try connecting the power adapter to another compatible HP laptop to determine if it is functioning correctly.

3. Examine the power socket and laptop DC port

a. Check for physical damage or debris

Inspect the power socket and the laptop DC port for damage or debris that may be blocking the connection.

b. Ensure a secure connection between the adapter and the port

Make sure the power adapter fits snugly into the laptop DC port.

c. Try connecting to a different power outlet

See if the problem persists when connecting to a different power outlet.

4. Reset the System BIOS

a. Understand the risks involved in BIOS resetting

Keep in mind that resetting the BIOS can potentially cause problems if not done correctly. Ensure that you understand the risks and follow the proper steps.

b. Follow HP’s guidelines for BIOS reset

Consult the HP support website or contact their support team for guidelines on how to reset the BIOS on your specific laptop model.

5. Explore potential hardware issues

a. Perform a hard reset of the laptop

Try performing a hard reset, which involves unplugging the laptop, removing the battery, and then holding the power button for around 30 seconds.

b. Check for RAM-related issues

If the problem persists, consider whether there might be an issue with the laptop’s RAM, as defective RAM can prevent a laptop from starting.

c. Consider consulting a professional technician

If you’ve exhausted all possible troubleshooting steps and the HP laptop still won’t turn on even when plugged in, it might be time to seek professional help from a technician.

Preventative Measures

Maintain healthy battery practices

To prolong the life of your laptop’s battery, try to avoid overcharging it and ensure that the battery never fully drains.

Use surge protectors to prevent electrical damage

Invest in a surge protector to protect your laptop from power surges that could potentially cause damage.

Regularly update system BIOS and other software

Keep your laptop’s system BIOS and other software up-to-date to help prevent compatibility and stability issues.

Keep the laptop clean and free from debris

Regularly cleaning your laptop by getting rid of dust and debris can help prevent problems related to airflow and overheating.


In summary, there are various potential reasons why an HP laptop won’t turn on even when plugged in, ranging from battery issues to hardware problems. By following the troubleshooting steps outlined in this article, you can effectively identify and resolve the problem. Not only will this save you time, but it will also ensure that your laptop remains functional and reliable.
