Found that FN+on/off button booted to the Dell PSA diagnostic we had used to 1st get a confirmation that the original HD failed.
Running PSA this time found the new HD was not set, but then it corrected that and it now shows in a list that the F12 key shows at bootup.
The F2 key, brings up the old DOS style BIOS. Here, it does not work if we try to enable UEFI, and there is no list of hardware devices should you want to re-order their boot preference.
Boots from hibernate in 30-40 sec, and Martha seems to think it booted faster back when UEFI worked.
Sleep works, but cannot seem to stop a hibernate/shutdown(?) after leaving it unattended for several hours.
Seems to be stable otherwise, and I hope it continues to.
