I'm having trouble using bitlocker. I recently disabled bitlocker before upgrading BIOS to 1.19.2.
I'm running the following setup:
Dell XPS 15 9560 Windows 10 Pro
I got TPM & Secure boot enabled in BIOS:
Running TPM.MSC gives the following:
Trying to enable bitlocker on C: gives this:
Viewing the TPM module in device manager shows no warnings or errors:
I re-installed Windows 10 multiple times. Using Legacy-BIOS mode and UEFI mode, both no succes. Current install is Windows 10 Pro UEFI mode. These are the specs:
Looking at the Security Provider Details in the Windows Settings, I get this information. It seems it is missing the Manufacturer and the Attestation? See print-screen:
I have downloaded and applied all SupportAssist and Windows 10 updates, see the following two print-screens:
Running PowerShell GET-TPM command shows the following:
I reviewed all existing issues and the Dell Support Most Common TPM document. But they don't seem to cover this explicit issue:
- It's available and enabled in BIOS; - it's visible in device manager and showing no exceptions.
I tried to revert to a lower BIOS version (1.18, 1.16 and 1.12). But ever since 1.19.2 Windows won't reboot normally. Every time I choose "restart" or an installation processes tries to restart, the device shutsdown. It wont come back to life. So I need to push the power button to start the machine again. I've checked that the Fast Reboot option is disabled:
Does any one got some advice on how to probably fix this? I will take all suggestions :).
