boothibernatewindows 7
I recently got a Windows 7 laptop from my office. I am observing that it starts up (boot up/ wake up from hibernate) whenever it is connected to power source. This happens whether it is in shut down or is in hibernated state. There is no change of state when it is already powered on.
This does not happen in my personal laptop. Does anyone know of any option that is causing this? And how to disable this?
Windows Update or Back-up and Restore shouldn't be doing this, search the root cause in your event log and also try the powercfg -lastwake command which will list what the last wake was.
Disable that option, see what powercfg -devicequery wake_armed lists and disable their wake.
Yes, you can have the Thinkpad go into hibernation from the sleep state. If the machine in connected to power, you can make it work by setting for sleep in 20 and hibernate in 25. This causes hibernation to kick in 25 minutes after sleep has started.
However, if you are running on batteries (as most people are who wants a sleeping machine to hibernate), it does require a BIOS configuration change. In the BIOS choose Config, Power and enable "Timer Wake with Battery Operation".
Warning: Lenovo do not recommend you do that as it may damage your hard disk if you are moving the machine around when it decides it is time to go from sleep to hibernate. Also you have to be sure about other scheduled tasks so they don't risk waking the machine and draining your battery.
