Holding ALT+TAB will activate the flip 2D to switch from a window to another. The problem is that this function remains active for a very short time and I'm not able to select the window I want in the foreground. I also noticed that when I put the cursor on an icon on the taskbar, the live preview thumbnail disappears quickly.
I noticed that this problem disappears in 2 situations: 1) with a safe mode restart 2) when I deactivate the charging of the battery from the manufacturer(Dell) software for the battery.
PS I can't remove manually the battery because the laptop is unibody.
Any suggestions for this annoiyng problem?
