Hello,
Thank you for posting in the HP Support forum.
Such things can happen due to hardware issues or software issues. From what you describe it actually froze, did not shut down automatically. It was you who removed the batter to force it stop.
You may want to review these articles from HP about similar situations:

Since this happened once only so far, I'd recommend you do not change anything at this moment but just check few major things to ensure the most critical parts are OK.
- You can go to Start >> Settings >> Control Panel >> Administrative tools >> Event viewer to review logs of latest activity.
You can check the Windows logs (Application and System).
Please, don't be scared if you see lots of Red or Yellow items - not all of them are critical - this is just a logging system
- You can check your computer for malware/viruses to ensure there are not any. Some could cause locks.
You can check with the free tools like these:

ESET Online Scanner >> http://download.eset.com/special/eos/esetsmartinstaller_enu.exe (www.eset.com)
Sophos HitmanPro >> http://www.surfright.nl/en/hitmanpro
Remove any threats if found
- Check Windows Update status in Control Panel and ensure it is not set to Automatic but instead set to to notify you before downloading and installing updates. Sometimes, if an updates takes longer to download/install, a computer might freeze.
- You can check your computer's hardware for hardware issues. Here is how to:
