When i switch on my laptop the wireless keyboard and mouse works but after sometime it doesnt i tried connecting it but it failed

Try bypassing the USB hub and plugging the receiver directly into a USB port on the computer. Sometimes devices won't recognize properly if they're going through a hub.

The GCS632U has keyboard and mouse emulation that may not work with all wireless combos. If your wireless combo is going to work the single USB connection would need to go into the keyboard port as that is the only port that will recognize the hot key switching commands. If the wireless combo still has problems then try using a USB wired keyboard to ensure the GCS632U is working correctly.

Did you ensure the ON/OFF Switch is set to ON? Did you also try replacing the batteries, then pressing the connect button on the receiver followed by the connect button on the bottom of the mouse?

Normal 0 Press the Receiver button (and the lights will start flashing.
Then if the Keyboard isn't working, press the small RESET/CONNECT button on the back of the board to connect the keyboard to the receiver.

If the MOUSE isn’t working, push the small RESET/CONNECT button on the back of the mouse to connect to the receiver. Then they should work okay.
Hope this helps. Bud

No need to disable the touchpad they should both work at the same time. Have you tried both the mice on another PC?. The first mouse should have the correct software already installed but you will most probably need to install software for the microsoft mouse. I hope you have tried resetting by hitting the button on the receiver then while its flashing the button on bottom of the mouse? If all this fails do have any other USB devices you can test on laptop?......good luck

PS I hope its not the batteries

you need adriver for it.

open the Logitech utility and try to reconnect the keyboard and pair it with the mouse. if it doesnt work uninstall/reinstall the software for your wireless mouse/keyboard.

Firstly, try changing the batteries in the keyboard.

If still has issues, try moving the receiver to another area. Try to remove from other sources of interference such as Monitors, Speakers and Power Supplies.

If this doesn't work, try using a non-wireless mouse, and see if the keyboard still has issues.

If all this fails, then I would consider replacment.

First download and run regscrub xp and ccleaner to clean up your system then try uninstalling and reinstalling the logitech setpoint software and try the keyboard and mouse again. Let me know if this works. 

once you have switched pc you will need to re-sync the wireless keyboard and mouse with the new pc, because although you have switched pc the keyboard and mouse do not know this. there should be a reset/resync button on the bottom of both the keyboard and mouse
