laptop switches off when unplug power cable

[clifftopdweller]

hi.
i recently noticed that when i unplug my laptop power cable, the laptop switches off within 10secs or so...
and when i reboot, get message about going into BIOS if i choose... i just reboot. and all is fine... but, can't use laptop with cable presently.

the battery is pretty new. i got a new one maybe around a year ago... so don't expect the batter is dead yet..
i pretty much use it plugged all the time, so as far as im aware, the battery is bypassed, and doesn't go through cycles of losing charge etc? is this the best practice? i heard from my tech friend that best to always use plugged, so not draining battery, allowing it to last longer.

so, any pointers on why laptop is switching off like this be much appreciated.
of course ive explored my settings. it's not something as simple as laptop switching off when unplugged.

here's what i see for my battery check, which all look great as far as i can see.

thanks.

Hi @clifftopdweller,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing an issue with your HP Product. Not to worry I will help you to get a resolution to resolve the issue.

It sounds like there might be an issue with how your laptop is handling power from the battery. Here are a few potential causes and solutions to explore:

1. Battery Connection Issue

Even though the battery is relatively new, it could still have a loose connection or some form of physical damage. Try reseating the battery:

• Turn off the laptop and remove the battery.
• Clean the battery contacts and the connectors in the laptop.
• Reinsert the battery and make sure it’s securely connected.

2. Power Settings

Check your power settings to ensure that your laptop is set to use the battery properly when unplugged:

• Open your power settings and make sure the settings for battery usage are appropriate.
• Disable any "Power Saver" modes or other settings that might affect battery performance.

3. Battery Calibration

Sometimes, the battery needs to be recalibrated to report its charge level accurately:

• Fully charge the battery to 100%.
• Unplug the laptop and let the battery drain completely until the laptop shuts down.
• Plug the laptop back in and fully charge it again without interruption.

4. Battery Health

Although the battery is new, it’s worth checking its health more deeply: acpi -i
 

5. BIOS Settings

Check if the BIOS has any settings related to power management that might need adjustment:

• Enter BIOS by pressing the relevant key during startup (often F2, F10, DEL, or ESC).
• Look for any settings related to battery or power management and make sure they are set correctly.

6. Battery Driver Issues

Although Linux handles drivers differently, sometimes reinstalling or updating your kernel might help resolve battery-related issues:

• Update your Linux kernel to the latest stable version if you’re not already using it.
• Check for any updates specific to battery management in your Linux distribution.

7. Hardware Issue

If none of the above solutions work, there might be a hardware issue with the battery or the laptop’s power circuit. In this case please run the hardware test HP PCs - Testing for hardware failures
 

Refer to this document:  HP Notebook - 14-bp076sa User manual 

I hope this helps. 

Take care and have a good day.

hi gaya,

thanks so much for the very detailed response!

im sorry i'm just seeing it now... i expected to get an email when response came, but didn't.. will look at my settings now.

so, seems there are quite some things for me to try...

from my last post today, i'm also seeing that my CMOS battery could need changing... if so, then i could likely take a look at both together, if possible...

will go through the list you've offered, and see which ones i can try out (without opening up the laptop, yet).

thanks again.
