Windows 10 Unexpectedly Shutting Down

I was using windows 8.1 on my laptop (HP ProBook 440 G2) and decided to completely format the disk and install Windows 10 from scratch. Downloaded the ISO from microsoft's website, installed it and upgraded to the latest version with all the updates available on the Windows Update. It's currently on Windows 10 version 1511.

The problem is, after long periods of usage ( don't know an exact number ), I would say more than an hour, when I close my laptop's lid, the power LED and the charging LED both start blinking and then windows just shuts down, with no messages whatsoever. Windows is configured to SUSPEND when the lid is closed, both when on battery and when charging. On a fresh boot, if I turn on the laptop and open a few apps and and then close the lid, it suspends normally like it should.

It used to work just fine on Windows 8.1. I tried to update the BIOS to the latest version but it didn,t work. Also tried to deactivate all "power saving" features from the BIOS, but also didn't solve the problem. All drivers are up to date, I manually updated every single one of them, but the issue persists. I'm running out of ideas. It's extremelly annoying when I need it to suspend and it shuts down and I end up losing some of my work.

The HDD is a Seagate Barracuda 5400rpm SATA III 500Gb drive, and it's brand new. It has less than 2 months of usage. All benchmarks seems fine, and Crystaldisk doesn't report any "health" issues, no bad blocks or whatsoever.

Anyone has a clue of what is going on? Really appreciate any help.
Thanks.

  1. Look in Device Manager for any entry with ! or ? to the left. That would indicate the need for a driver you should get from your manufacturer's web site.

    Good luck.

    There is no driver needing updates, as I said in my post, I manually updated every single one of them. I managed to narrow down the culprit to the Intel(R) Wireless Bluetooth driver, which wasn't entering sleep mode, causing some sort of malfunction and making the system shut down unexpectedly. Disabling the driver worked, the system is suspending just fine again, but I'm seeking for a way to make it enable Bluetooth again and keep it all working, since I use Bluetooth now and then.
