I should be writing a 5 star review.  Laptop arrived 2 days ahead of schedule.  It is in almost new condition.  I'm not a stranger to purchasing refurbished products.  The 2 comments alone should be enought to give a better rating.  The issues are the battery and charger.  I'm very familiar with the Lenovo T480.  I purchased to have a slim light laptop.  This laptop came with the extended life 6 cell battery.  5 hours estimate battery life. To many this  may have been a happy accident but this extended life battery make the laptop heavy and bulky,not what I was expecting.  The after market charger, while it has printed on it that it is a 65 watt charger, when rebooting the laptop there is a DOS message that an insuffienct charger is attached. This again is likely because of the larger battery.  I sent messages to the seller thru Amazon.  Amazon sent a reply asking if the seller had responded and solved my issue.  The seller has not replied.  I asked the seller if an exchange of battery to the standard could be arranged but no reply at all.
