Try cleaning it before you mess with any settings.

Cause:
Your keyboard or number pad may collect dust and other deposits from regular use. Occasional maintenance helps keep the device looking clean and functioning properly.
WARNING: Before cleaning any electrical device or equipment, ALWAYS remove the device from its power source.

Solution:

  • For cordless keyboards or number pads, remove all batteries before cleaning.
  • For the diNovo Edge (a rechargeable keyboard with a built-in, non-removable battery), or any other similar device, switch the keyboard OFF before cleaning.
  • For corded keyboards or number pads, shut down your computer and disconnect the keyboard from the computer before cleaning.
Keyboard and number pad cleaning suggestions:
  • Use compressed air to blow dust and other debris from between the keys. Logitech suggests using an air duster squeeze bulb specially made for keyboard cleaning to limit the force of the air pressure.
    NOTE: Avoid using high pressure air hoses and nozzles. Excess air pressure can remove keys or cause other damage to your device.
  • Use a small tipped vacuum cleaner to remove dust and other debris from between the keys. Logitech suggests the use of a small tipped vacuum cleaner specially made for keyboard cleaning. Many come with USB power cords and can run off your PC or laptop.
    NOTE: Avoid using vacuum cleaners other than the type previously described. An excess vacuum level and/or large vacuum tip can remove keys or cause other damage to your device.
  • Use a dry, lint-free, non-abrasive micro-fiber cloth to gently wipe clean the surface of your device. Logitech suggests using cloths which are specially made for keyboard cleaning.
    Note: Avoid using dusted disinfectant cloths or cloths dampened with liquids unless specifically designed for keyboard cleaning. Many cleaning solvents, chemicals, and other liquids can cause electrical and/or material damage your device. This includes leftover residues which can eventually damage your device over time.
Additional information:
Many consumer electronics stores and online re sellers offer third-party computer cleaning kits which include dry wipes, swabs, air duster bulbs, and micro-fiber cleaning cloths. Some higher-end cleaning kits come with keyboard vacuum cleaners, and/or product-safe disinfecting liquid for dampening wipes, for use in disinfecting the surface of the device. These liquid disinfectants are supposed to be non-conductive electically; quickly evaporate from the sevice and leave no residue. Logitech suggests you make sure these characteristics are plainly stated and guaranteed on the product package. These specially made keyboard cleaning kits are highly recommended.
IMPORTANT NOTES:
  • DO NOT pour any liquids onto the device.
  • DO NOT submerge the device in any liquids.
  • DO NOT use a dishwasher, ultra-sound cleaner, or any other washing machine to clean your device.
  • DO NOT remove keys from the device.
  • DO NOT use cleaning solvents. Many cleaning solvents contain caustic chemicals which may cause damage your device.
  • DO NOT use drying machines, fireplaces or ovens (even set at lowest temperature) to dry moisture from your device.
Removing keys; submerging or pouring liquids on your device; using washing machines; exposing your device to excessive heat; or using caustic cleaning solvents may cause permanent damage to your device and will void the warranty.

I'd suggest downloading the most recent software and drivers for the Performance MX mouse to see if that makes a difference. You can get that software directly from their site at this link: http://www.logitech.com/en-us/428/783?section=downloads.

They also have a fairly good FAQs and troubleshooting section for their products. Your devices page should be this link: http://www.logitech.com/en-us/support-downloads/downloads/mice/devices/783.

If neither of those help you'll have to contact Logitech directly regarding your warranty question. You can either email them or call them, and their contact info is listed on their website: http://www.logitech.com/en-us/support-downloads.

How to make logitech keyboard & mouse work??


Hi there: I was also facing the same problem. But when you see on back of the keyboard the instructions are there. or follow these steps.
1. insert new batteries both in keyboard and mouse. 2. decide what device you want to connect 1st (Lets connect Keyboard first) 3. Pres and Hold the connect button for both key board and receiver for about 5 secs. 4. don't press any key on key board till 10 secs (During this time it trying to connect with receiver) 5. Check the key board connectivity if it works then take it away or put it behind some barrier so that when you are connecting the mouse it don't interrupt. 6. now for the mouse do the same process as you have connected the keyboard.(step 3 & 4) 7. now check both key board and mouse they will work fine. Thanks
