I came into a MX Mechanical (full size) at a local discount store, and though new in box upon opening it revealed a dent on the top right corner. That established, the device takes power and has a full battery, the LED pulses when charging, but the on switch doesn't seem to serve any function, as it doesn't present itself for discovery. I've tried Bluetooth on three different devices, the included bolt receiver and an older logi unifying receiver all to no avail. I've gone as far as dissembling the device, and though the brown cable does appear a bit pinched, it isn't by any means (visibly) severed. I've tried the Esc+O (2x), Esc+B, reset along with Esc+Fn all to no avail. I'd appreciate any guidance!

• latest firmware
• blow air to clean dust (sometimes help for little while)
• turn off&on power
• change to bluetooth connection
• change RF receiver

My fix was to disconnect one of the wires inside of keyboard to totally disable proximity sensor.

Logitech do not want to own the issue.

Really sad when you pay nearly $200 and it barely outlasts the warranty period. Last Logitech peripheral I ever buy but would love to see if there's a way to salvage this paper weight. Would like to know which replacement parts might be available and when so I can weight out my options.

until another character is keyed in eg an S so you get aaaaaaaaaaaaaaaaaas and then the letter a wont work till the keyboard is switched off then back on and you get the letter a...aa again.

I have taken the A cap off the keyboard and cleaned around underneath but its still stuck so suppose the microswitch/ contact/ logic gate is permenantly closed. Without a disassembly protocol/circuit diagrame or spare parts available can this be fixed?

!!!!!!!!!!!!!!! I should add that using another standard MS keyboard all characters work properly but no access to Swedish spcial ones !!!!!!!!!!!

I understand besides the ML2032 can one use other re-chargeables like VL2032 or LIR2032 ?

VL2032

VL Battery Chemistry

A Lithium Ion chemistry that works well in camcorder and rechargeable electronics applications. Batteries with the VL designation have no memory effect, meaning they can be charged to full capacity at any point in the charge cycle. You don’t need to empty the charge before recharging.

VL Batteries:

Have a high energy capacity

Are perfect for camcorders

Can be recharged at any point in the charge cycle

LIR2032

LIR Battery Chemistry

Unlike the other chemistries, the LIR chemisty has a voltage of 3.6V instead of 3V. This chemistry is rechargeable, however a protective circuit is absolutely necessary due to the very high energy density of this type of cell. LIR2032 batteries are frequently used in car security systems, memory backup batteries in electronic devices, electronic watches, and many other applications.

LIR Batteries:

Have a voltage of 3.6V rather than 3V

Have an extremely high energy density

Are rechargeable, but require a protection circuit

My Logitech K810 Wireless Keyboard suddenly started typing weird. As example if I type "A" it give "LA" (both for uppercase and lowercase) and even more oddly it does the same when I type "L" (results as "LA"). Adding on that when I type "S" it results as "S + Enter" and vice versa "Enter" results as "S + Enter". The left arrow gives an "M" and this weird issue appeared the day I came back from a long vacation when everything was OFF (keyboard, mouse and ofcourse the desktop PC). I did try to remove the driver for both the keyboard and bluetooth receiver but it didn't help. I have no clue how and why that happened. I never, absolutely NEVER spilled water or any other liquid on it. Logitech support didn't give any rational answer except telling me that the warranty is already off. Some other letters on the keyboard act weird as well. Does anyone have any clue what could have happened and if there is any way to fix it? Any useful answer would be highly appreciated. Thank you!

I bought myself a wireless solar keyboard which worked perfectly until I poured some drink into it.

I dissasembled it and washed it in distilled water and isopropyl alcohol. Upon battery replacement, the keyboard worked well until the battery became flat.

In the photos is non-rechargeable batter cr2032, however the rechargeable had same results.

I am getting appropriate voltage from the solar cells but the rechargeable LED-indicator doesn't light up upon pressing the button and the battery eventually runs flat.

I am no pro in circuit board repairs, any suggestions will be appreciated.

I read that you've just started offering all OEM parts for this product and was hoping to buy a replacement body kit (I believe that's the correct term).

Where on your site might I find this part?

Many thanks, in advance, for your help!
