5 minutes after delivery I put the adapter in the ThinkPad to test with an LCD it work despite not enough resolution ... when removing the pc surprise there it blocks despite having to press the brake to disengage nothing to do it remains stuck abnormally I redo the manip it comes off of a plastic in my hand and pine remains in the pc so c damn it reminds me of China products, I am a computer and know manipulate my devices so that means everything. In summary functional but too fragile product may damage the HDMI port without problems of thinkpad
