Acer Aspire One sleep problem

[macschwag14]

Hi!

I bought an old Acer Aspire One D250/AOD250 and installed Win 7 Professional on it. Everything was working fine for a good month until just a few weeks ago, when suddenly the sleep function would do a hard shutdown on the netbook. It now doesn't matter which way I do it - close the lid, push the power button, or use the keyboard function - the sleep function kills the machine.

I've updated the drivers and checked my power options. I even switched sleep to hibernate, but now hibernation is a suicide option as well:confused. Seriously confused about this one.

Thanks!
