I purchased this computer for my wife for Chrismas along with the 2 year extended warranty offered by Amazon since it was refurbished.  Worked ok during the 90 Amazon warranty then the  Bluetooth /wifi  USB  module  went bad.  I tried going through Amazon and the extended warranty company and got nowhere.  I finally went through another source and finally got another one but was without internet for 2 weeks.  Further, I purchased external speakers for the computer through Amazon which worked well for a month then quit.  I ordered a set of speakers through Amazon thinking the first ones were bad and the second set will not work either.  Plugged both sets into an old computer and they both work.  So obviously it's not the speakers...It's the computer.
