I do not know anything about computers and bought my last computer 10 years ago.  I do not like the fact that this computer did not contain an owners manual and the serial number on the back of the console is not correct in fact it's unsearchable.  It looks like they put the wrong one on by accident.  I looked it up internally by running a program. The serial number given internally did not have the full name of product bought or a manufacturer date.  I went online for technical support and called an Acer technician and they were unable to get this information for me.  They had part of the name of the model, but not the full name so incomplete model information and no manufacturer date and it's impossible to know.  I am keeping the computer, but just letting everybody know.
