Many Logitech products look alike, but use different parts. To ensure that you get the correct replacement, you'll need to find the part number of your Logitech device and match it to one of the numbers displayed in italics below the descriptions at left. This number will be in the format of P/N:8xxxxx or 8xx-xxxxxx, and can be found in the following locations:

Bottom or rear of device

Underneath battery cover

Behind foam ear cushion

Go here and put your number in: http://buy.logitech.com/store/logib2c/en...|downloads||dd

Here how to replace it:

Carefully peel off the orange back of the keyboard. Do not tear it as we will replace it during reassembly.

Remove the 19 screws. 19th screw is under the black Bluetooth sticker under the charging pin.

Pry open the keyboard.

Replace the battery.

Sqeeze the keyboard back together making sure the on/off switch functions correctly.

Looking at the glue patterns on the gray side of the orange backer mark each screw.

Drill all marks with a 5/16" drill bit. This will allow the keyboard to be taken apart without peeling off the backer next time.

Spray the gray side of the backer with spray adhesive (3M Spray Mount in my case).

Press the orange backer back in place.

Very thorough +

The instructions are a bleeping nightmare. I'll go buy a wired one thanks. Cheaper than a mechanical engineering degree.

i thought mayer's description was pretty good!

Mayer, I thought you did an excellent job of explaining this procedure and along with the youtube video to change the Dinovo Battery, https://www.youtube.com/watch?v=x0b0rMDY...

Wired keyboards are my choice ;-)

Hi,

I have, somewhat, the same problem.

I've tested the battery and it's fine, I took it to a specialist and he told me that the chip responsible is the one controlling the charging process.

Is there a schematic for this keyboard?

He showed me the part but the text printed on it is "home labeled". How can I find the correct part?

He told me it's the first chip above the battery connector on the board. (20+4 pins).

Thanks

Update

Here's an image

can you describe the symptoms of your failed chip. Ive replaced my battery but i still doesnt stay charged for long. when charged it flashes red->red->red->green is the battery likely faulty? i could buy a genuine logitech battery but its getting to the point where i might as well buy a new keyboard...

Permanent Solution to Logitech diNovo Edge Planned Obsolescence Battery Problem

If you don't really need a wireless keyboard, here's a permanent solution that is working for me.

Main parts required:

- Jameco Electronics 1-Amp Power Supply Kit, Item # 117621 ($14)

- case opener

- small screwdriver

- quick connect

- small box

- male connector to draw power from your PC's power supply

- 2-conductor low-voltage wire

You need to know how to open the keyboard. The video from Newpower99

https://www.youtube.com/watch?v=x0b0rMDY... shows you how.

1. Build and test the power supply.

2. Adjust the voltage to about 4 volts. Dialing it in precisely is a little hard. Mine is set to 4.1 volts and it seems fine. The battery states a rating of 3.7 volts, but when I first adjusted the power supply it didn't work. I checked the output on the battery, and saw on my DMM that it was putting out a bit over 4 volts. They keyboard draws about 40 milliamps so you don't need to worry about sucking too much power from your computer.

3. Remove battery and solder your leads to the battery connector cable. I forget the polarity, just copy the polarity shown on the battery. The center contact on the battery is for a thermistor and it sends 4 volts. They keyboard won't work unless you bridge one of the leads to the center contact as well.

4. Make a small hole in the keyboard case, run the line out to your quick-connect.

5. Run the quick-connect to your computer. I'm pulling 12 volts off the yellow wire, but it will probably work pulling 6 volts off of the red wire too.

No more battery charging issues.

No more waiting for charging the battery.
