Help! I backed up my Acer Aspire E5-551-T374's recovery partition to the USB with the erecovery software already installed on the computer. Later, after I re-partitioned the hard drive removing all of the partitions including the hidden recovery partition, I tried to restore it with the USB recovery stick. I plugged it in and set the USB as the first thing to boot in the BIOS. When the normal Acer boot logo came up, it stayed there until I force shut it off. I noticed that at some point it will shut off by itself if it is unplugged. The battery was not dead though. If anyone had this problem and they know what it is, that would be great!
