I purchased based on the rating placed on the item (excellent).  Excellent is the top rating for renewed laptops.  This item was not at all in the claimed condition. CMD prompt Battery Health report revealed "no batteries at all."  Even after being plugged in for 90 minutes.  Then the laptop started turning off repeatedly after a warning flashing on screen "need to install a working battery." False advertising to rate this item as "Excellent Condition."  I've now had seven of these "Amazon certified renewed" laptops, all rated in Excellent condition.  Every one of them were "maybe" in the Poor category.  Lenovo ThinkPad T480's are very good machines, but apparently not from these renewers here on Amazon.
