SONY PCGRT170 Lid closure sensor - getting to it

Threaded View
I have a SONY PCG GRT170 laptop.  It looks as if the lid closed sensor
is preventing the display backlight from illuminating.  I can activate
the backlight by pushing on the switch with a screwdriver - although
the backlight isn't as intense.

Looking at the bottom of the laptop, I'm trying to determine which
screws to remove.  I want to try this before opting for repair.

I believe that the GRT is assembled buttom to top as the GRV is, so
disassembly is top to bottom.

Remove the DC power, the battery, and any peripherals. Start at the top.
  The trim containing the power switch and speakers has a retaining
screw on the left margin.  If this is like the GRV it will be hidden in
the USB or iLink port areas.  Remove the screw and slide the trim piece
left about 1/4 inch and lift up gently. Place against the screen.  You
can then see a retaining screw for the keyboard that swings up and to
the front.  Both the trim piece and the keyboard have ribbon cables that
are very fragile.  Do NOT remove either end of these cables unless you
are prepared to replace them.  The interior is accessed by removing the
sheet metal emission shield.

Further disassembly involves removing the bottom screws marked with ==>
to remove the palmrest assembly.

Find a service manual for it, laptops are incredibly complicated to
disassemble if you don't have some idea. There tend to be hidden
screws under keyboards and other stuff on the top of the case, and
annoying plastic or metal clips that hold the case together.
