Helix 1st Gen won't boot after fan replacement

2019-09-26, 10:53 AM

I just finished replacing the fan and heat sink in the tablet portion with new heatsink compound.  Initially the tablet portion was working ok but the keyboard was not working.  I couldn't get anything after trying several times to reset the keyboard and the tablet.  I took the tablet apart and double checked all of my connections and when I put it back together it won't boot up now.  I've tried reseating all the cables and resetting the tablet many times and nothing is working.


I really like this laptop and would really like to salvage it.  Is there anything I may have missed that might get this working again?

I haven't worked on that model in a while, but I remember 2 things.  There was a cable that ran from under the motherboard to the top surface, near the battery that was easy to forget.  Also, there are 3 cables from the LCD to the motherboard (video, misc. connections and touch) that are fairly tight.  They can be difficult to get inserted all the way.  The whole machine is tightly packed. Just reseat all the connections
