There have been some reports for some machines experiencing delayed or missing keystrokes at the Preboot Authentication screen (PBA). The following models are currently known to have this issue:
*HP 250 G7 (System ID 8532)
*HP 250 G8
This issue is observed with both Symantec Endpoint Encryption (SEE) and Symantec Encryption Desktop (PGP).
This issue is observed only with Non-US English keyboard layouts configured for the preboot screen.
HP and Insyde have included a fix for this and will be released soon.
One of the workarounds to this issue is to plug in an external keyboard, which has been known to allow full keyboard entry.
Alternatively, setting the keyboard layout to US English while this is being reviewed will allow proper keystroke entry.
To do this with Symantec Encryption Desktop (PGP), run the following command:
C:\Program Files (x86)\PGP Corporation\PGP Desktop>pgpwde --set-language --disk 0 --keyboard en --display en --admin-passphrase passphrase

To do this with Symantec Endpoint Encryption (SEE), run the following command:
C:\Program Files\Symantec\Endpoint Encryption Clients\Drive Encryption>eedadmincli --set-language --disk 0 --keyboard en --au adminUsername
This will prompt for the passphrese, and once entered, the keyboard layout should be set to US English. Run the following command to confirm:
eedAdminCli.exe --get-language -d 0
Important Note: If you are unable to use the above options or you are affected by different models, reach out to Symantec Encryption Support for further guidance. In all of these cases, it is possible to invoke a temporary bypass so that the preboot could be skipped. In these situations, you would be required to login to the Windows prompt rather than the preboot screen.
