PXE-E61 Error message showing due to Media cable failure.You have to fix this media cable failure one must return to the BIOS screen at start up. Depending on the model of the laptop, press f1, f2, or delete to enter the BIOS screen (the computer will tell you what keys to press). At the bottom of the BIOS screen, there will be a menu. One of the options should be "setup defaults." By pressing the corresponding key, it will return all of your settings back to how they where originally. Hopefully it will help you

if the key is actually broken, you need to order a replacement, if it is not broken and is still in one piece it should be very easy to reconnect, you just need to find someone who knows how to reconnect keys
