Probook 440 G8 Freezing on battery after March 2026 updates

[JamieLucas]

After March Windows updates HP Probook 440 G8 and some Elitebook 840 G7's are freezing only when on battery power. nothing in event logs, installing OOB windows updates doesn't help. installing the latest driver and BIOS doesn't help. rolling back doesn't seem to help either. Is there an official acknowledgement or fix from Microsoft or HP?

Do this:

- Press Win + R, type services.msc, Enter.
- Find HP One Agent Service, right-click > Properties.
- Set Startup type to Disabled; click Stop if running > apply and ok.
- Close window, restart laptop.
- Test it.

Thanks but we don't have that service on our laptops.

Perform clean boot it will disable 3rd party startup apps and the one causing this. You can use those app normally when open it just won't launch automatically.

Perform Clean Boot:
1. Press Windows + R, type msconfig, hit Enter.
2. General tab: "Select Selective startup," uncheck "Load startup items."
3. Services tab: Check "Hide all Microsoft services," then "Disable all"; Apply.
4. Startup tab: Click "Open Task Manager," disable all enabled items; close Task Manager.
5. OK > Restart; test

The issue is still persisting after doing this

So Far i have found that updating to KB5086672 and running the below commands on an elevated CMD has (for the time being) stopped the crashing. This does seem to drain the battery more but that is better than the crashing. I will try to contact HP and Microsoft with this information as it seems to be caused by a bad update/driver/firmware etc.

reg add HKLM\SYSTEM\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0 /f

and

powercfg /setdcvalueindex scheme_current sub_processor PROCTHROTTLEMIN 50

powercfg /setdcvalueindex scheme_current sub_processor PROCTHROTTLEMAX 99

powercfg /setdcvalueindex scheme_current sub_processor IDLEDISABLE 1

powercfg /setdcvalueindex scheme_current sub_sleep STANDBYIDLE 0

powercfg /setactive scheme_current

We have also found that reinstalling Windows and simply updating to the latest KB5086672 has also seemingly resolved this issue.

Never mind, both reduce the crashing but the issue is still persisting.

So someone today said that it can be intel driver issue too. So to check. Download DDU (Display driver uninstaller) from browser. 

• Then Boot into safe mode, then open DDU, and if the Options window doesn’t appear, click the "Options" button; then check "Prevent downloads of drivers from Windows Update when Windows search for a driver for a device" (found at the bottom), and after selecting these, close the Options window. 
• Set the device type to GPU.  Select GPU brand to Intel, click "Clean and Restart". When the system boots normally after this, the uninstallation process is complete. 
• Now visit HP driver page of your laptop, download and install Intel VGA driver or use hp support assistent if installed. (Don't use driver directly from Intel that they may be causing freezing issue).

After installation, restart and check.

Hi, how are you? Were you able to solve this problem? I'm experiencing the same issue on several devices of this model.
