I am an extensive Windows user but this problem has me totally confused. I have done lot of searching on web but cannot find a good answer.
Windows 7 home premium, 64-bit
HP Envy 3D laptop with 8GB memory, no custom hardware
I have configured a backup job which wakes up the laptop at midnight, takes a backup and puts laptop into standby again. All this happens with the laptop lid closed. The power scheme is configured to put laptop into standby when lid is closed.
The resume from standby, backup and suspend after backup is controlled by Windows Home Server (2003) console which is installed on the laptop. I had purchased the HP laptop in October of last year and this job used to work just fine. Sometime in March of this year, the backup stopped working.
After checking the logs and physically observing the laptop at midnight, I found that the laptop resumes from standby at the scheduled time but immediately goes into standby if the lid is closed. The backup fails. Windows event logs indicate that laptop lid close action is putting system into standby.
If the lid is open, then the laptop resumes from standby, stays awake, backup proceeds and laptop goes into standby again.
Here are my problems:
a) Why did the backup work for several months and then stopped working?
b) I have other laptops in the house running Windows 7 home premium on variety of hardware (all HP) and they do not have any issue. Even with the lid closed, they resume from standby, do a backup and go into standby again. The power scheme on all these laptops is set to put laptop into standby when lid is closed. I have verified from physically observing the laptops during backup time.
I have checked all the usual suspects like BIOS updates, driver
updates, run sfc, completely deleted the Windows Home Server console from laptop and re-installed after deleting all past backups but nothing seems to help. Is there some setting that I have overlooked? Any ideas will be greatly appreciated.
