I am running Windows 7 in an Acer Aspire E1 771 laptop. It’s about 1 ½ years old but has not been used much in this time. Recently, when I try to shut down the computer it goes into a “sleep” or “hibernate” mode rather than turning completely off. (I’m not sure which mode it is in.) If left for several days, the battery is low or dead. When I try to start the computer (using the power button) after experiencing this type of shut down, there is no response. In order to restart the unit I have been removing and replacing the battery. (It starts using the power button after doing this.) I’ve checked the Power Options / Choose What the Power Buttons Do and the power button is set for “Shutdown”. I’ve investigated this problem “on line” and found that I can bring the computer back to life by pressing “Windows key” and releasing it, followed by pressing ‘right arrow’ twice, and then enter. I’ve also found that I can get the unit to completely shut down by pressing “Windows key” and releasing it, followed by ‘right arrow’ once, and then enter. The computer worked fine for the first year or so. This problem as developed in just the past 2 or 3 months. If anyone has comments or other suggested diagnostics that should be performed, please leave comments. Thanks in advance.
