[jayrhu12]

I bought my Laptop HP 15s 3045au on January 30, 2023, now I have a problem regarding the battery power icon showing and stuck on 99% while I'm using it will auto shutdown without warning, and that is a time saying my laptop needs to charge even it showing 99%. I already reset my PC to default factory settings and I always run for a battery check and say my battery is normal. I know my battery is normal because this is brand new, but I am not sure, The issue is how can I monitor my battery if do I need to charge it. Because it will always show and be stuck at 99%? I already follow the instruction what is saying but here but nothing happen still stuck at 99%  HP Notebook PCs - Testing and Calibrating the Battery (Windows) | HP® Customer Support

Hi @jayrhu12,

Welcome to HP Support Community.  

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

For better clarity and to assist you better I would require more information regarding this:

• Has it worked before when you first got it? Did it charge to 100%?
• Did it happen after a software or Windows update?

For now please try these steps:

Please uninstall the ACPI battery drivers from device manager by following these steps:

• Right-Click on start button> click device manager> expand Batteries>then select all the drivers including the ACPI drivers and uninstall it one at a time. Then restart the computer and check again.

If it does not get resolved, then calibrate the battery and restore the power plan to default. Link to calibrate the battery and restore power plan to defaults: http://hp.care/2syuGOs

Then update the bios and chipset drivers from this link http://hp.care/2syreDe and follow the on-screen instructions.

Then check if the issue is resolved.

If it does not, then continue troubleshooting by following these steps:

Also, go to power options>change plan settings under balanced option> advanced power settings> Low battery level> on battery> change it to 20%

• Do the same for plugged in also.
• Critical Battery level > change it to 10%
• Plugged in > also to 10%
• Low battery notification>  change it to on
• Plugged in and also change it to on.
• Low battery action > Change it to Do nothing
• Plugged in > change it to do nothing
• Reserve battery level> change it to 10%
• Plugged in> change it to 10%
• Then check if it gets resolved and shows the battery notification when the battery levels deplete.
• For further assistance, please follow all the relevant steps that match your current issue from this link: http://hp.care/2syheXK
• Also, make a note of any failure code for a failed component like the battery or adapter (charger)
• Please re-calibrate the battery as well from this link: http://hp.care/2symZV5

Some tips to enhance battery life:

• Please always charge the battery to 100% and use it on battery standby.
• Then when the charger is plugged in, there is no issue here. However, when you continue to sue the computer on battery standby, make sure to drain down the battery to lower than 15% before recharging the battery again.
• Once in a while, for example, once in 15 days, save up all your work when the battery shows a notification that it is low on charge and allow it to drain down completely before charging again, which enhances the battery’s life and performance.
• This across devices like camera, cell phones, or notebooks.
• This is because, with each charge and discharge, the battery completes 1 charging cycle and the life cycle of the battery diminishes.
• The battery has a life cycle of a standard amount of charges and discharges only. (depends on the size of the battery)
• It is never a good idea to charge the battery to 100% and deplete 30% of its charge and connect the charger to it again.
• Because you lose out on 70% of its remaining charge and complete only battery charging cycle if you plug the charger back to charge the battery.
• As it goes from 70% to 100% charge and completes 1 charging cycle.

Also, this link: http://hp.care/2iykJdH should help if the temperature of the battery raises,

Please perform all these steps patiently as it is critical to resolving the issue. 

I hope this helps. 
Take care and have a good day.
