Changed battery but still no signs of life?

I have bought and replaced the battery with an Maxell ML2032, but the keyboard doesn't show any signs of life. There is no green or red LED in the top right corner and the keyboard is not found by the unifying software. Each of the solar panels gives about 1.5v output when tested with voltmeter and the battery itself gives just over 2.8v (the old battery has less charge and gives about 1.2v).

Is there anything else that I might be able to do to fix the keyboard, I don't want to have to replace it?

Thanks in advance for any suggestions.

Scott.

Turn the battery over. With the keyboard right side up you should see the smaller negative side up.

You could have a look at the power (On Off) switch. On my K750, this switch is starting to fail causing symptoms like you describe.

I have this problem (Logitech has put obsolescence on the switch too to kill the keyboard). Curiously, the switch is always "on" and drain the battery even if we do not use it.

Have you solve the problem ? How ?

Thanks.

Hi Scott, my guess would be that the logic board may need to be replaced OR a cable could have come dis-connected from the board or the battery itself. I suggest trying to re-install the new battery.

Turning battery over was the game changer, installed replacement wrong and then just put old one back in (battery goes in opposite of what you'd think). Also used a hack of turning off keyboard, holding CAPS LOCK down and pressing buttons for 5 seconds and then turning keyboard back while under direct light.... .those 2 things revived my keyboard.

Larry Jackson and Rob Lazott, you both just made my K750 keyboard go from dead to back to life! Thanks so much for the tips on turning over the battery AND the CAPS LOCK trick. I'm back to seeing green! :D
