Yes, you can use the laptop without the AccelerometerP11. That is a solution available on Dell laptops and it's said to protect the laptop's hard drive, but if it's not compatible with Windows 10, then it might be removed automatically. However, it doesn't mean the laptop won't work anymore. It's just a simple feature that won't be available. If the laptop will be fully supported on Windows 10, then you might expect the return of AccelerometerP11 in the future. The software is not available for downloading. It's automatically embedded on Dell by Dell Technicians.
