accelerometerdll.dll system error

[danielbarra]

Hi guys,

I recently aquired a refurbished HP Envy x360 - model 15t-AQ100.

When I boot the pc, I get te message that there is a system error and that accelerometer.dll is not being found. ("AccelerometerST.exe System error. The application cannot start because accelerometerdll.DLL is missing on your computer. You could potentially solve this by reinstalling this application.")

I have already uninstalled the 3D driveguard device, rebooted my pc and installed the latest HP 3D DriveGuard Software (HP ProtectSmart Hard Drive Protection). The file name is sp81142.exe.

After installation, I rebooted and i still get the same message.

Also, two times, when my pc was turning the screen around (I was using the notebook upside down, for presentation mode), I got a blue screen informing that the pc had stumbled on an error and had to restart.

Don't know if that is related.

Can you guys please give me a hand? I'm going crazy over this.

Hi,

Try the following.

Download the version of HP 3D DriveGuard on the following link and save it to your Downloads folder.

http://ftp.hp.com/pub/softpaq/sp81001-81500/sp81142.exe

Download and install the x64 version of 7-Zip on the link below.

http://www.7-zip.org/

When you've installed 7-Zip, open your Downloads folder, right click on the sp81142 package, select 7-Zip, select extract files and then click Ok.

Cut this newly extracted folder and paste it on your Desktop so it's easy to find.

When done, hold down the Windows key and press R

Into the Run window, type devmgmt.msc and hit enter.

In Device Manager, expand System devices, right click the HP Mobile Data Protection Sensor entry and select 'Update Driver Software'.

In the following window, select 'Browser my computer for driver software' and then select 'Let me pick from a list of device drivers on my computer'.

In the next window, click the 'Have Disk' button and then browse to the extracted  sp81142 folder you pasted on your Desktop.

Browse into the sub-folder InstallFiles, open the folder Win10, left click on the file accelerometer to highlight it and then click Open.

Click on 'Ok' and then click 'Next' and wait for the driver to install.

When done, click 'Close' and then click 'Yes' to restart the notebook.
