HP Laptop 15s-fq5347TU battery discharges while hibernating

[ppantangco]

hello everyone. i noticed that my laptop discharges fast over time while it is hibernating. i do understand that batteries discharge over time even if the laptop is not in use, but this seems to be extreme. attached is a screen shot of the battery usage over the past 7 days while the laptop is hibernating.

the laptop actually discharged completely over the second half of the week. the first half of the week it slowly lost charge over a period of 3 days, then completely discharged over the next 2 days.

@ppantangco, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Based on the graph and your description, it does seem that your HP Laptop 15s-fq5347TU is experiencing unusually rapid battery drain even while in hibernation, which typically should consume negligible power. Here are some key points and troubleshooting steps you can take:

Why this might be happening

• Hibernation not fully triggering: Sometimes the system may appear to hibernate but actually enters a low-power sleep or connected standby state.
• Wake timers or background activity: Certain Windows settings or scheduled tasks may intermittently wake the system.
• Fast Startup: Enabled by default in Windows 11, it can cause the system to partially hibernate but still allow some background processes to run.
• USB or peripheral drain: External devices (USB dongles, receivers, etc.) may be drawing power during hibernation.

Recommended Fixes

Check for Connected Standby

• Open Command Prompt (Admin) and run: powercfg /a
• If you see "Standby (Connected)", your system may not truly hibernate. Disable it via registry if not needed.

Disable Wake Timers

• Go to Control Panel > Power Options > Change plan settings > Advanced power settings
• Expand Sleep > Allow wake timers and set both Battery and Plugged in to Disable.

Turn off Fast Startup

• Go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable
• Uncheck Turn on fast startup (recommended)

Update BIOS and drivers

• Go to HP Support and install the latest BIOS, chipset, and power management drivers specific to your model.

USB selective suspend

• In Power Options, under USB settings > USB selective suspend setting, set to Enabled.

Run Battery Report

Run:

• powercfg /batteryreport

Then open the generated HTML file and look for irregular sleep/hibernate/wake events.
 

I hope this helps. 

Take care and have a good day.

Thanks for the reply to my support request. Here are the things I have managed to do:

Check for Connected Standby - disabled this as per your instructions

Disable Wake Timers - disabled

Turn off Fast Startup - turned off

I also updated the BIOS, but I did not do USB selective suspend since this was not found in the Power Options on my laptop.

However, there still seems to be some battery drain over a couple of days since I did these:

The previous 5 days it was on AC power and was thus at 100%. I applied the changes on the fifth day and placed the laptop on hibernate. It went from 100% to 93% in a couple of days. That still seems to me to be an unusual battery drain.

@ppantangco, Thanks for the detailed update, and good job systematically applying the changes. From your latest battery chart and observations, it looks like the discharge rate after all optimizations is roughly 7% over 2 days of hibernation.

Additional Suggestions to Try:

Force Hibernate via Command Line

Use this command to ensure you're invoking a true hibernation state:

shutdown /h

Then monitor battery levels over the next 24–48 hours again.

USB Selective Suspend Workaround

Even if the setting isn’t available in the Power Options GUI:

• Run this in Command Prompt (Admin):

powercfg -attributes SUB_USB 2a737441-1930-4402-8d77-b2bebba308a3 -ATTRIB_HIDE

• Then check again in Power Options > Advanced Settings > USB Settings to enable USB selective suspend manually.

Check for Wake Events (Just in Case)

Open CMD as admin and run:

powercfg /lastwake
powercfg /waketimers

These commands help check if anything is waking the system even briefly, which can disrupt hibernation.

Battery Report Insight

If this still doesn't solve the issue, generate a battery report:

powercfg /batteryreport

Open the resulting .html file and check for unusual activity during the hibernation period (especially in the "Usage History" and "Battery Capacity History" sections).

I hope this helps!

The previous solution to this appears to have worked as my laptop only drained by 1% over 7 days of hibernation.

I tried applying your new proposed solution -

USB Selective Suspend Workaround

Even if the setting isn’t available in the Power Options GUI:

• Run this in Command Prompt (Admin):

powercfg -attributes SUB_USB 2a737441-1930-4402-8d77-b2bebba308a3 -ATTRIB_HIDE

Copied and pasted this to the command line but i get an error message of invalid parameters.
