I have an Acer Aspire R7, which has had the same issue since I bought it. When I shut down the machine, the creen goes black, BUT THE MACHINE DOES NOT POWER DOWN. The only way I have ever been able to shut off my machine is to do a FORCE SHUTDOWN.
Again, this issue was supposed to be fixed (4 times) by Acer when it was under warranty and the issue continues.
When I try to contact Acer for them to fix the machine, I am told I have to pay for the service, EVEN THOUGH THE PROBLEM WAS NEVER FIXED (THE FOUR TIMES I HAD TO SEND IT TO ACER)
SOMEBODY PLEASE HELP!
