Logitech WIRELESS SOLAR KB & MSE MK750 Repair

The MK750 Wireless Solar combo pairs Logitech’s slim, full‑size K750 solar keyboard with a Marathon-style wireless mouse in a sustainable, low-profile package. The keyboard is powered by an integrated solar panel and designed for everyday productivity with a numeric keypad and ultra‑thin profile. The product is built from durable plastic materials and low‑profile keycaps, with an emphasis on sustainability across components and manufacturing. Key features include wireless operation via a USB receiver, long run time from light exposure, and multiple regional keyboard layouts.

Common repair-relevant faults include loss of charging (solar panel/battery), unresponsive keys, and wireless connectivity failures.

For key faults, remove keycaps to inspect for debris or switch damage; re-pairing or receiver replacement often resolves connectivity issues.
