SOURCE: replace keypad gateway w340ui

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
great help.

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
be sure.

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.

I how do I replace cmos battery

Get in contact with Gateway before you change it. On some devices removing the CMOS battery and leaving it out for about 1 minute will clear all passwords, but please check with Gateway first, as it may result in you bricking your PC.

Need to replace cmos battery in Gateway MP8708

Power down PC. Open the PC tower. Look at the motherboard and find the CMOS battery. Looks like the picture below. Make sure you touch some sort of metal area on the PC to ground yourself before touching the components. Use something thin to pop the old CMOS battery out. The CMOS batteries are usually universal. CR2032 is the usual type used. These can be found at a CVS or Walgreens. Once you have acquired the next battery, make sure the CR2032 is facing up and just press it in.

CMOS location in gateway model # 6332

The CMOS battery on the Gateway M-6332 is located either next to or underneath the WiFi card. With the laptop upside down, loosen the three screws along the rear edge of the panel next to the fromt of the laptop. Remove the panel and you'll see the hard drive and the WiFi card. There will be one or two Mini PCI Express slots. I've replaced the mainboard in this one, don't recall if the original only had one slot, the one I installed has two.

That's where the CMOS battery is, held to the board with a piece of double sided tape and connected by a pair of wires to a small plug.

What is the correct battery for the BIOS memory for a Gateway model 4025GZ notebook ?


When 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 and need to be replaced. You can swap out a dead CMOS battery with a new one by removing the Gateway computer's side access panel.

Difficulty: Moderate
Instructions Things You'll Need:

  • Phillips-head screwdriver

  • CMOS battery replacement

  1. 1

    Shut down the computer. Remove the power cable from the back of the computer case. Disconnect the cables for the monitor, mouse, keyboard, and printer.

  2. 2

    Set the computer case over on its side. Use the Phillips-head screwdriver to remove the two case screws at the far left end of the case.

  3. 3

    Slide the side access panel to the left and remove it from the computer case. Find the CMOS battery port, which will be located to the lower left of the processor in most Gateway computer models.

  4. 4

    Lift up the plastic clip holding the CMOS battery in place. Slide a fingernail under one side of the battery and lift it off the motherboard port.

  5. 5

    Check the orientation of the new battery and compare it to the CMOS motherboard port. Push the new battery into place in the same direction that the old battery was facing. Push down the plastic clip.

  6. 6

    Set the side access panel back onto the Gateway computer case and reattach the case screws. Plug in the Gateway computer and power it on.

I have a Gateway W340UI. powercord connection

When you wriggle the plug in the power socket on the laptop and the charge LED flashes and in the right position it charges, this indicates that the power socket is faulty or there is a dry solder joint on the motherboard where this power socket is attached.
To get at the power socket will require dismantling the laptop completely. A computer repair shop can do the repair, I suggest you get a quote first.

Gateway 450rog cmos battery

The CMOS battery is located on the motherboard, just under the bottom left side of the keyboard, by the letter 'V". It looks like a clock battery, marked 3V (volts). The battery comes out of its "cage/connector" by gently lifting it with a small flat screwdriver. Replacement CMOS batteries are inexpensive and readily available at any computer shop. Hope that helps
