My Omen notebook is not charging above 75% and does not turn on unless plugged to the charger

[lexsilva1]

My Notebook started behaving very strangely yesterday. It turned itself off out of nowhere and then back on. After that i noticed the battery was charging but at 75%, which is stranger given the notebook has been plugged to the charger all day. I though it might not be connected properly and unplugged the charger to plug it again. as soon as i unplugged it the computer shut down. and without the charger plugged in it wint turn on.

@lexsilva1,

Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Check the Power Adapter and Charging Cable

• Inspect the charger and cable: Ensure that the charging cable and adapter are not damaged. Look for any visible frays, bends, or signs of wear.
• Try another outlet: Plug the charger into a different power outlet to rule out a possible problem with the socket.
• Test with a different charger (if available): If you have access to another compatible charger, try using that to see if the problem persists.

Perform a Hard Reset

A hard reset can often fix power issues by resetting the internal components.

• Disconnect the charger: Unplug the charger from the notebook.
• Remove the battery (if removable): If your notebook has a removable battery, take it out. If not, skip this step.
• Hold the power button: Press and hold the power button for about 15-30 seconds. This will discharge any residual power.
• Reattach the battery (if removed) and plug the charger back in.
• Turn on the notebook: Try to power it up again.

Check Battery Health

• Battery Status/Health: Many laptops have a built-in diagnostic tool to check the battery’s health. Depending on your system, there might be a way to access this from the BIOS or through software. For example:
  • Windows: You can run a battery report by typing powercfg /batteryreport in the command prompt. This will generate a report on your battery’s health.
• Battery Wear: If the battery is in poor condition, it may not charge or hold a charge properly, even when plugged in.

Check Power Settings

• Battery Settings: Ensure that your power settings are correctly configured, and that the laptop isn’t set to shut down when it reaches a certain battery percentage (in case there’s a power-saving setting causing it to shut off unexpectedly).
• BIOS/UEFI Settings: Some systems have power-related settings in the BIOS or UEFI that could be impacting the battery charging process. Access your BIOS/UEFI (usually by pressing F2 or F12 during startup) and check for any unusual settings related to power or charging.

Test Without Battery (If Removable)

• If your laptop has a removable battery, try running it directly from the power adapter without the battery installed. If it powers on, it indicates the battery might be the issue.
• If the system doesn’t turn on, it could mean an issue with the motherboard or power components.

Inspect the Charging Port

• Physical damage: Check if there is any dust, dirt, or visible damage in the charging port. Clean it gently if necessary.
• Connector problems: Sometimes the port may become loose or the internal connections might be damaged. If the charger isn't being properly detected, it could be due to issues with the port.

Update BIOS/Drivers

• Sometimes issues with charging and power management can be fixed by updating the BIOS or firmware. Check your laptop manufacturer’s website for any available updates, especially those related to power management or charging.
• Update Drivers: Make sure your power management drivers are up to date.

Consider Battery Replacement

If you’ve tried all of the above and your notebook still behaves strangely with charging, it could indicate a failing battery. If the battery is not holding charge or causing instability, it may need to be replaced.
