ISB Port One of my ISB Ports, on the back of the Laptop, stopped working. It isn't getting any electrical power. For example, I plug in my mouse and no light.

Things I see here.
1) The second Keyboard you plugged wasn't any good either.

2) The PS/2 port for your keyboard on your motherboard, isn't any good anymore.
Computer off, plug it into the Mouse PS/2 port, and use a USB mouse.
BIOS will reset the I/O address for that PS/2 port, and set it for the Keyboard, when the computer is turned back on.

You may have to;
A) Turn the computer off
B) Unplug from power.

C) Press the Power On button in, and hold it in for a count of 10 seconds. Let go of the Power On button. Do this same procedure two more times.

What you are doing is draining residual power, clearing CMOS Error Codes, and resetting BIOS back to the factory default settings.

Keyboard plugged in, USB mouse plugged in, plug the computer back into power. WAIT 1 minute, turn the computer on.

Still no?
Motherboard replacement.

You didn't unplug the old Keyboard, WITH the computer on, and plug the new Keyboard in, did you? It isn't a hot-swap device. The computer must be off when unplugging a mouse, or keyboard.

For additional questions please post in a Comment.

Make sure the hardware associated with the mouse (cord, plug, etc.) are working properly and plugged into the correct port in the computer. After this is complete restart your computer. If the problem persists contact me.

Make sure there is nothing touching the trackpad on the laptop, as that will stop the mouse functioning correctly.

You could also try attaching the receiver to a different USB port on the laptop, to make sure it isnt a dead USB port.

Lastly, you could try downloading and re-installing the drivers from http://support.microsoft.com/kb/258785

• Put in the batteries Find the battery covers and slides it off. Insert the appropriate batteries. The wireless receiver that plugs into the computer runs off the computer's power and needs no batteries.
• Plug in the receiver to the computer. Usually the receiver will plug into the USB port, but some plug into the mouse port. If all of your USB ports are filled, see if the mouse came with a USB adapter. The adapter fits into the mouse port. Be careful not to accidentally force the mouse adapter into the keyboard port.
• Connect the mouse once you have it plugged in. The receiver should have a visible button that is easily push able by the average human finger. The mouse will usually have a very small hole with a button inside it that can only be pushed by something like a pencil or paper clip. Push both buttons at the same time with the receiver and the mouse relatively close to each other for about 5 seconds or more.
• Position the receiver in a place that isn't far away from the mouse. Depending on where you are, you can place it on the monitor, on the tower, on the back of your laptop (if you are installing the mouse to your laptop) or on the desk. The furthest a wireless mouse can get away from the receiver without working very well is about 9 feet (2.7 meters), so keep that in mind.
• Test your new mouse.

Hope this help. Goodluck!

get a reg. computer mouse plug in your port then go to start then go to programs and files tool bar put the mouse in you will see 2 mouses go to your lap top mouse click on now change settings around then restart laptop.

unplugged the power cable for a minute and plug it back let the power drain. if you are using laptop, take out the battery

Get a new mouse. On my opinion I perfer a ball mouse then a laser type mouse because they just break fast.

see the very first thing is that what u can try is that try and connect the same mouse that u had and that had worked and if works then the prob is with the mouse that u have right now and if that also doesnt work then the usb port on the laptop has gone bad and u need to replace the motherboard of the computer but before replacing the motherboard try and connect some other usb device on the same usb port.........

try to get a mouse built for laptops or get a mouse from the same brand as the laptop. and check to see if when you plug in the mouse on screen it says 'new hard ware found' if not it is not reconizeing it.
