Hello, I've noticed that my Windows Task Manager and CMD - command "systeminfo" shows me wrong boot/up time my Windows 7 machine. Have a look at this screen:http://img412.imageshack.us/img412/3323/systeminfo.pngWindows Task Manager shows me this value:http://img145.imageshack.us/img145/4118/wtmsysinfo.pngSo it shows me only my online uptime without sleep or hibernation time - it's OK, but why in CMD "systeminfo" value Boot Time still changes (when I sleep and wake up my machine) and shows incorrect data (should be 2009-11-12 not 2009-11-16)? Any ideas? (Today date: 2009-11-19) Thanks,

I have noticed that others have the same issue connected with sleep/hibernate mode:http://superuser.com/questions/52027/windows-7-systeminfo-reporting-incorrect-system-boot-timeStill no solution of this problem.

I see this problem too (Win7Pro x64). The event viewer confirms that the system last rebooted several days earlier than the Task Manager or systeminfo reports it rebooted. (Also, I leave a lot of windows open all the time and would have noticed if they had disappeared due to a spontaneous reboot.)

I have the exact same problem. Running Windows 7 x64. i think it does differentiate between sleep/hibernate and rebooting.

Looks like a BIOS update might cure some of these ACPI problems. Vote if answered or helpful, I am running for Office (joke)! IT/Developer, Windows/Linux/Mainframe
