Scheduled tasks and hibernation

[Ebbe]

Hey!

Q 1:
I have scheduled a task (backup, using a .bat script, running some Winzip
tasks) to run at a certain hour.
The task is set up to "Wake the computer to run this task".

I have also instructed the power manage system to hibernate after 30 minutes
of inactivity.

The question is:
What happens if the scheduled task last longer than 30 minutes?
Will the system suspend the running task after 30 minutes run, or will the
system hibernate 30 minutes after the task has ended?

Q 2:
My normal login on the computer has no password.
When I try to run a task using the scheduler under the user without
password, she scheduler claims that the task was not run because of no
password.

I have then added an other user on the computer and added a password to that
user.
Scheduled tasks under that user runs perfectly.

Is it impossible to run scheduled tasks under a user, that has no password?

Hi Ebbe,

1) Hibernate should set in 30 minutes after the task completes. However, if
the machine is hibernating when the task is supposed to begin, as opposed to
just being in standby, then the task will not run. Hibernate is a power off
state, so nothing is running at that point. The only difference between it
and a shutdown is that it preserves the current user state by copying the
ram contents to the hiberfil.sys file before shutting down.

2) See:

However, from MVP Kelly (a workaround):

For Pro: Start/Control Panel/Administrative Tools/Local Security
Policy/Local Policies/Security options.
In the right hand pane (third down). Accounts: Limit local account use of
blank passwords to console logon only. This is enabled by default, disable
it.

For Home: Backup your registry before modifying. Locate the following
registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

Value name: limitblankpassworduse
Type: REG_DWORD
Data: 0 (disabled) 1 (enabled)

It is enabled by default. Disable it and scheduled tasks should run.

Hey Rick

1) Hibernate should set in 30 minutes after the task completes.

My computer is able to wake up from hibernation and run a task.
Do I understand you correctly, that this running task will not bee
interrupted by a new hibernation, if it last more than the 30 minutes?

Hi,

Your computer is able to wake from standby and run tasks, not hibernate -
they are two different things. Hibernate mode is the same as a power-off
except for the contents of the ram being saved. Standby would not interfere
with scheduled tasks in most cases.
