The gateway w340ui is a LAPTOP if I am correct.
Please refer to my other posts on the topic of replacing
laptop keyboards, if you can find them for detailed
INFO common to most laptops.
Every laptop is different, and the first challenge is to find
and download a disassembly manual from the WEB.
You want to GOOGLE for the keywords:
Gateway w340ui Disassembly
Many people put up diagrams and instructions for free.
If this fails, the look to D/La service Manual, which will give
you all the info you will ever need plus some, bu it may
cost a few bucks. $15 is reasonable, $20 is pushing it.
Anything over that is a scalper.
Most keyboards are easy to replace, but the challenge is
getting the cabinet opened. The disass'y manual will be a
1) Shut down Windows
2) Turn off the PC using the power switch.
3) Unplug all the cables and remove the main battery
(This step is very important)
4) Press the power button again as if trying to turn the
PC back on. This should drain any remaining power in
the internal capacitors, but give it a few minutes just to
5) Now you need to get the top off. This may require removing
all plug-in gadgets, floppy, CD drive, Internal Hard drive...
etc. to get at hidden screws from below....
or there could be hidden clips and catches from the top.
There may even be a single hidden screw near the
keypad's perimeter, underneath one of the keys,
which will allow the keyboard to slide out.
Sometimes you can slide a very small and thin exacto
knife in-between the plastic body sections to see where
the binding posts are.
6) Once you have physically plucked out the keyboard or
remove the top cover, you will see a very thin ribbon cable,
(transparent, thin, flexible printed circuit) connecting the
keyboard to the main board.
7) This cable is extremely fragile and very tightly inserted
into the edge connector.
It can be very hard to take out and even harder to put back in.
8) When removing it use long, hooked needle-nose pliers,
and gently tug at each side of the cable until it comes
out. Wrap some soft tape over the pliers to make sure
you don't damage the printed circuit on the ribbon
cable. Take you time !!!!!!
When putting it back, alignment is very critical, and you
have to use the pliers to bend the cable so it is perfectly
aligned and parallel to the connector. It will NOT go in
at an angle or if it is not in the same plane as the
connector. Don't FORCE it, but it has to go all the way in.
Hooked plastic surgical clamps or tweezers also work,
but always wrap something soft around jaws:
tape, rubber tubing, etc.
Hope this helps,
place rate my answers.

your Gateway computer is
switched off, it still keeps track of various system information such
as the date and time, thanks to a small battery that never powers
off. The size and thickness of a dime, the CMOS battery can run out

fingernail under one side of the battery and lift it off the
