Yes, I followed one of those in the past when I changed the fan, but 
it's not a ribbon rather a round cable ...

Dell Inspiron 15R Owner’s Manual*

p35 Removing the Display Assembly

Prerequisites
1 Remove the battery. See "Removing the Battery" on page 13.
2 Remove the keyboard. See "Removing the Keyboard" on page 15.
3 Remove the base cover. See "Removing the Base Cover" on page 17.
4 Remove the palm rest. See "Removing the Palm Rest" on page 27.

p27 Removing the Palm Rest

Prerequisites
1 Remove the battery. See "Removing the Battery" on page 13.
2 Remove the keyboard. See "Removing the Keyboard" on page 15.
3 Remove the base cover. See "Removing the Base Cover" on page 17.

Procedure
1 Remove the screws that secure the palm rest to the computer base.
2 Turn the computer over.
3 Lift the connector latches and pull the pull-tabs to disconnect the 
power-button board cable, touchpad cable, and hot-key board cable from 
the connectors on the system board.

[11 screws and three connectors over and above what you've already 
removed to get this far, then 'spludge'  -  perhaps that should be 
'kludge'  -  the palm-rest off the base, and only then can you access 
the hinge screws and the display and WiFi connections.]

Incidentally, this is a model where only an option made at purchase time 
included an extra card connector on the underside of the daughterboard 
for the card slot(s), so most daughterboards don't even have the extra 
connector, meaning you can't upgrade a second-hand/used machine with an 
onboard SSD unless you can somehow get hold of a daughterboard with the 
extra connector, and even then you must go through all the above and 
more just to fit an onboard SSD.  By comparison, with a Precision M6700, 
you simply take off the bottom cover  -  just two screws.  It rather 
reminds me of stories of having to take the engine out of a mini to 
change the battery, or the Citroen GSA (IMS) where everything was so 
cluttered under the bonnet that to do any significant work in there was 
an absolute bloody nightmare.

* A Dell irritation, what effectively are Service Manuals are frequently 
called Owner's Manuals.

It means they distort the sound verging on unacceptably.

Not worth it, second-hand maybe, but then you don't know whether the 
replacements would be any better.
