"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."
