I previously owned and used an HP Elitebook 8470P daily for 11 years (not a typo).  Started out with a Windows XP O.S. and ended up with Linux Mint on it.  Best machine I ever owned but physically wore out, with the final straw being the screen/lid hinge broke.  Yes, it was heavy and yes, it was tough.Purchased this refurbished Elitebook with the main difference being a SSD vs HDD.  As advertised, SSD is notably faster, especially during startup/boot. The Windows OS was replaced with Linux Mint OS again (personal preference).  Everything appears to be in satisfactorily working order with no complaints.  DVD, speakers, bluetooth, mic, camera, cpu temperature, all perform well.  All specifications are as advertised.  After one week, very content with this product.
