I made the mistake of waiting too long to power the computer up. It is cripplingly slow even after time to update and restarts. I emailed tekrefurbs (they suggest email for quick resolution) hoping for some kind of product support as a courtesy- help with a diagnostic, etc. as many companies still offer some basic phone or online support after warranty. After they did not respond to my email for 5 days, I called. They stated it is out of warranty and ended the call. Reality is they shipped a defective product. I can't say what their warranty service would have otherwise been.
