Touchscreen not working after disassembly and reassembly

[DavidNick]

I have a HP ENVY  Product: E1P14AV Model: 17t-j100.  The left hinge was broken and the fan locked up so I took it apart and found dozens of little pieces of plastic and loose gromets inside the machine.  A gromet was lodged in the fan causing the fan problem.  The left hinge was broken loose and was so hard to operate that it is no wonder it broke loose.  To adjust the hinge I had to remove the touchscreen.  After adjusting the hinge, I cleaned out all the plastic,  secured the hinge and put everything back together. It all works well except for the touchscreen.  The computer does not seem to recognize that there is a touchscreen. In settings I get the message that "no pen or touch input is available for this display. " It worked fine prior to my working on the system.  Please advise what I should do to resolve this issue!  Thanks for any help!!!

Thank you for joining HP Forums. 

I'll be glad to help you 🙂 

As I understand the touchscreen not working after disassembly and reassembly

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

If you did the reassembly on your own, did you ensure the digitizer cable was connected properly?

Have you ensured all cables and connections are secured well before putting the panels back on?

While you respond to that, I must let you know that HP doesn't recommend replacing or reassembling parts as such unless a HP Certified tech is working on the PC, that said, if you are able to ensure all cables are back in where they belong and yet the issue persists, you may attempt to check if the touchscreen works on the BIOS screen (tap on F10 to access during a restart) and if it doesn't work on BIOS as well., it would be confirmed to be a hardware malfunction and I recommend you Contact HP to set up a repair/replacement service order:
