I have sahara n1356 laptop which freezes mouse and keyboard when i start it. what could be a problem
Try following tips:
Try to connect your keyboard and mouse directly to your laptop's USB
ports (instead of using the USB hub) and see if they still freeze.
It sounds like you're using an unpowered hub, which in my experience
tends to cause most common errors with USB peripherals. It's definitely
not recommended to connect any USB devices which aren't supplied with a
power adapter (for instance some 2.5" external HDs and those small
photo printers). These sort of devices should be connected directly to
your laptop at all times.
You could also consider buying a powered hub,
i.e. an USB hub which draws its power from a separate power adapter
(and not your single laptop USB port).
if it doesn't work you can try this..
Click Start, and type device manager in the Start Search box.
Click Device Manager in the Programs list.
If you are prompted for an administrator password or confirmation, type your password or click Continue.
In the Device Manager dialog box, expand Universal Serial Bus controllers.
Right-click USB Root Hub and then click Properties.
In the USB Root Hub Properties dialog box, click the Power Management tab.
Remove the check from the Allow the computer to turn off this device to
save power check box. Repeat steps 1 through 4 for each USB Root Hub
listed in the Device Manager.
Under Power settings, check the 'USB settings' -> 'USB selective suspend settings' and make sure it is disabled.
Check Thumbnail, highlighted: Open Device manager, Double click on
Universal Serial Bus controller at the bottom, Double Click USB Root
Hub, Click Power Management on top right, Uncheck Allow Power...
Hope it works for you.
