If you DO NOT have the mouse plugged DIRECTLY into a USB port built into the laptop, try unplugging whatever you have plugged to a USB port, such as a multiple port Hub, and plug the mouse DIRECTLY into the USB port built into the laptop.

If that doesn't get rid of the message, try unplugging everything plugged into all USB ports built into the computer.

If that doesn't get rid of the message, examine the USB ports built into the laptop to see whether any of them are damaged. Is the plastic blocking plug that prevents you from plugging in a USB plug upside down still there ? Are any of the metal contacts in the port bent or touching another one or touching the port's metal exterior (shell) ? You may need to flip the laptop upside down to see the contacts in the port.

(You can also examine the USB plugs on the USB devices you plug in to see if they are damaged.)

If that doesn't get rid of the message, either there is a loose connection inside the laptop or something inside the laptop is damaged.

Those things can be commonly caused by:

- dropping the laptop or subjecting it to a physical jolt otherwise.

- spilling liquid on the laptop, or exposing it to liquid such as rain or by spraying it with liquid.

Less commonly - the laptop was subjected to a power failure event that produced power spikes or power surges that caused damage, when the AC adapter was plugged into it.

Are you using a hub like tubesandwires asked? Do you have an internal memory card reader in your computer?

tubesandsand------ thanks for your reply it looks like it could be due to a over all power surge to my house as my home appliances are all effected. time to call the power guys.

tubesandsand, I like that one, LOL

When the power in the house fluctuates it can affect the final product going to the components in your computer. That is true. However, it may not affect them nearly as much as appliances that run on 120VAC as the final current.

Your power supply has both a transformer and a DC rectifier inside. 120VAC is converted to 12VDC, 5VDC & 3.3VDC. The motherboard further reduces the current to less than that for your processor and RAM, possibly other items too. In addition, your power supply may be capable of running on input current ranging from 100VAC to 240VAC. What I am saying is that even if you are having issues with the line voltage, your final current to the hardware components may still be within specs.

Download a monitoring program like speedfan that can sit in the tray and provide real time measurements. That will tell you for sure if the current is within specs.

SIW will also supply the voltages on the various rails. Get both Speedfan and SIW at the links below.
