HP Latop 15 battery drained in sleep mode

[GeneralSherman]

I got a HP Laptop 15 the other day and was using it plugged in while working, but unplugged it before I put it into sleep mode. When I went to unsleep the computer the next day, the battery was totally drained. This hadn't even happened with my old Dell, whose battery had started to go. What's going on that it drain a full charge in sleep mode in less than 24 hours?

My settings are simple as is what happens when I push the power button. Everything sleeps at no longer than 15 minutes of inaction, so it definitely wasn't - or shouldn't - have been awake when I closed it down for the night.

Hi @GeneralSherman,
 

Welcome to HP Support Community.

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

Here are a few reasons why your HP laptop might be experiencing excessive battery drain while in sleep mode. Here are some troubleshooting steps and considerations:

Power Settings:

• Make sure your power settings are configured properly. Go to "Control Panel" > "Power Options" and check the settings for when your laptop is on battery power. Ensure that the sleep and hibernate settings are configured appropriately.

Update Drivers:

• Ensure that all your drivers, especially graphics and power-related drivers, are up to date. Visit the HP support website for your laptop model and download the latest drivers.

Windows Updates:

• Make sure your Windows operating system is fully updated. Sometimes, Microsoft releases updates that can address power management issues.

BIOS Update:

• Check if there's a BIOS update available for your laptop. BIOS updates can sometimes include improvements in power management.

Background Apps:

• Some background applications may prevent your laptop from entering a low-power state. Check your task manager to see if any applications are using a significant amount of CPU resources.

Network Connections:

• Disable or adjust your network connections' power settings. Sometimes, network activity can prevent your laptop from entering a low-power state. Go to "Device Manager," find your network adapters, right-click, and check the power management settings.

Hybrid Sleep:

• If you are using hybrid sleep, try turning it off. Hybrid sleep writes the contents of memory to a hibernation file in addition to keeping it in RAM, which can consume more power.

Wake Timers:

• Check for wake timers that might be preventing your laptop from entering a deep sleep state. You can do this by running the command prompt as an administrator and entering the command: powercfg -waketimers

Battery Report:

• Generate a battery report to see if there are any irregularities. Open a command prompt as an administrator and type: powercfg /batteryreport. This will create a report detailing your battery usage.

Run a battery test: https://support.hp.com/in-en/document/ish_2268927-1713329-16
If the test fails, it must be a hardware issue.
 

I hope this helps.

Take care and have a good day.

The BIOS and driver update suggestions are far too general for me to know what to do. We're going to have to narrow this down. My computer sleeps when I push the button, close the screen, or after so many minutes not in use.

Hi @GeneralSherman,

Welcome to HP Support Community.

Thank you for your response.  I will try my best to help you.
Since you have done the steps mentioned above. I suggest you to please perform a system test on the unit.
 
Please  Click Here  to perform the system test.
If the system test is passed, I request you to perform a system restore.

Restore your computer when Windows starts normally:

If the computer stops working correctly, but Windows starts as expected, you can restore it to a previous point in time when it was working.

Restore your computer when Windows starts normally

• Restore your computer to a previous point in time.
• Save any open files, and then close all open programs.
• In Windows, search for and open Create a restore point.
• On the System Protection tab, click System Restore.
• 
• In the System Restore window, click Next.
• Select the restore point you want to use, and then click Next.
•        
• Review your selection, and then click Finish.
• Read the warning about not interrupting System Restore, and then click Yes.
• System Restore returns the computer configuration to a previous point in time and restarts the computer.
  
  Please take a backup of the data 🙂

I hope this helps.

Take care and have a good day.
