Who I have the same questioned this topic

I have a Verizon 8800L hotspot and it overheats.  It gets very hot to the touch and says it will not continue to charge until it cools off.  It is not near any heat source.  This started to happen a month or so ago.  Before that (for over two years) it worked fine.  Is there a solution that will not require me to purchase a brand new unit?
