Hello, Larry. My name is ***** ***** I'll be happy to assist you today. I'm sorry to hear that the upgrade didn't turn out well. I have experienced this a time or two myself.I haven't taken apart an Aspire E-15 specifically, but with any laptop, upgrading hardware is a tedious process.
You said the display doesn't work. Does it stay completely off or does it brighten-up but stay black? What I'm trying to find out is if any power goes to the monitor at all.
