Quite a mean feat to accomplish on some machines. I've run into:
BIOS needed an update.
CMOS battery was on the edge.
RAM failure (in sleep our RAM is keep alive so RAM issues can exist in Sleep but no where else which confuses some.)
BIOS settings (try S1 versus S3).
When I first installed Win 7 RC about a month ago, I was initially very impressed with what I saw. My computer was "perky or snappy". However recently it has started to slow down loading programs, etc.
Now, the last couple of days, it has locked up in the sleep mode. I assume its in the sleep mode as I left it running when I left. Previously, all I had to do to bring it out of sleep was to move the mouse a couple of inches.
Now, the only way to wake the computer is to hit the reset switch and do a reboot, pausing at the screen about "safe mode-normal mode". After continuing the boot process, it works normally except that it has lost the snappy feeling.
I haven't loaded ANY games on the system. The only 2 programs I have on the machine are Office Pro and Quicken.
I hate to say it, but it looks like I'm sinking into a Vista like slime pool. If this is what to expect when the program comes out in October, I won't be buying it.
This morning I've turned off going into sleep mode to see if that prevents lockups.
Very disappointed at the moment.
