Absolutely. Leave it alone, you don’t need to run the risks of removing this cable, I did the replacement fine without it
The new speakers don’t come with adhesive, so some double sided tape is handy. Also, the right speaker cable can be rather long, so some tape is useful to carefully loop it out the way.
This is the GPU failing, see the solution above. It gets either stuck on a grey screen, or sometimes just goes through an endless rebooting loop
