Mom's computer is getting a message that Acer's power management is not compatible with Win7 and that we should contact Acer for an upgrade.  She has an Aspire One D257-1648.  She is finding that she can no longer fully shut down the computer, it appears to hang with a blank screen.  A forced power off can be done by holding the power button.  Can someone help. Thank you!
