Logitech K750 Keyboard: Changed battery but still no signs of life?

Tue, 24 Feb 2026 16:32:42 -0700

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.

Logitech K750 Keyboard: There's a key too sensible, can it be repaired?

Wed, 26 Mar 2025 10:58:41 -0700

Y got this keyboard second hand, after some time figured out that a key (B in this case) is too sensible, just holding softly the finger on it gets pressed, this does not happen in other keys, I understand that something is broken in the inside, do you think this can be repaired? I've heard that this can be the membrane, and is costly, does not worth it, any clues? Thanks in advance.

Logitech K750 Keyboard: The on/off switch does not work anymore

Wed, 30 Oct 2024 01:42:45 -0700

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

Have anyone solve the problem ? How ?

Thanks.

Logitech K750 Keyboard: Can I use other rechargeable batteries?

Wed, 14 Feb 2024 05:47:01 -0700

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

Logitech K750 Keyboard: Caps Lock LED Indicator?

Sun, 16 Jan 2022 23:11:51 -0700

Is there supposed to be an LED indicator for the Caps Lock key on my Logitech K750 keyboard?

Passwords that require mixed characters where you can't see what you are typing are a real pain if you hit caps lock instead of shift.

Logitech K750 Keyboard: How are the plastic parts under the spacebar arranged?

Fri, 23 Apr 2021 07:45:33 -0700

I cleaned under the spacebar but can’t properly snap it back into place. There are four black plastic rectangles that must be positioned correctly for it to snap back. I’ve tried several arrangements for the rectangles but can’t find the correct one. Logitech won’t publish a simple picture of the proper configuration. Is anyone else able to show or describe the proper configuration of these small plastic rectangles under the spacebar?

Logitech K750 Keyboard: Keys stop being responsive.

Wed, 22 Apr 2020 03:08:27 -0700

I have been using this keyboard for years and I really like it.

I only had to replace the battery two times.

Unfortunately some keys are gradually becoming less responsive, requiring more force to be applied to register a key press. Notably the 7,8,9 numbers on the numpad and the ~ key under the esc key.

I have seen that it can be opened but can it be fixed by simply cleaning the internals or something similar? Or are replacement parts of any kine required?

Logitech K750 Keyboard: Do you sell replacement plastic feet used to elevate the Keyboard?

Tue, 16 Jul 2019 23:21:11 -0700

One of the plastic feet used to elevate my K750 keyboard broke and the only place I can get the replacement feet (pair) is from the US website for Logitech but they do not ship outside of the US.

Do you have an equivalent part available that I can purchase and have delivered to Australia?

Many thanks

Logitech K750 Keyboard: Battery recharging in solar keyboard doesn't work after water damage

Thu, 15 Mar 2018 07:04:39 -0700

Hi,

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.
