PC crashes when it wakes up from sleep
Posted on 2011-03-01
I know this is a really complicated situation to troubleshoot, but here is my problem. My media PC running windows 7, freezes when waking from sleep. The HDD light remains perminantly on. Sometimes the computer gets to the desktop but I cannot do anything as it freezes after the first interaction I make with the computer.
I have reinstalled Windows 7 with the BIOS already set to S3 before hand and that has made no difference.
When I use 'powercfg /a' it reports it's good for S3, but when I use the program 'dumppo.exe admin' it says the minsleep is S1
If I type the command 'dumppo.exe admin /ac minsleep=S3' it reports the change but after a reboot of the system it's back to S1 again.
'powercfg -energy' reports a few errors with USB but then so does my laptop and that works fine.
Funny thing is, if I put the PC into hybernate it boots up no problem at all!!!
I have spent months on this and been googling for hours but nothing works. The only solution is to leave it on 24/7.
Sometimes after a wake fail, the HDD is not listed in the BIOS so the PC does not boot-up untill I shutdown and power off completely again, then I have to enter the BIOS to place that HDD 1st in the boot seqence.
My question is, does anyone know of any tips?
Is the HDD simply not powering up after resuming from sleep?

Hope someone can help.
