There is a problem with the power supply cable that I have found in several of these. The wires break or short at the plug. You can purchase a replacement Multi-volt power supply from Walmart, set it for no more than 5 volts and plug it into the fan. It will work. I actually have mine set at 1.5 volts. Another problem with this could be that the USB port you are using is not coming on or has shorted out. Test the port with a thumb drive to make sure it still works. If it does then use the external power supply.

What are the other ports used for, and can I use them to run the fans?

Do you mean the USB-ports on your laptop? If so, than yes, you will need one free USB-port to connect the Chill Mat to.

Acer laptop comes on then turns off

Sounds like the CPU is overheating. That's about how long it takes if there is no cooling to it. Check the air inlet and exhaust openings on the sides of the laptop. Listen for the fan(s) when you turn it in. If the ports are clogged, or the fans are not operating, this is a good reason for your problem. Many people will try to use a laptop laying on a bed or sofa. This can cause blockage of air intake and result i overheating and overworking the fans causing premature failure. A computer repair center can replace fans, or you can get a good quality external cooling mat to aid you.

I got a Targus PA248U Notebook Chill Pad, the part inside where I plug the cable in is messed up I think and it won't power on. How do I open it up to have a look to see if I can fix it?

I opened the case and hard wired the power cord directly to the wires of the fans. There are 4 philips-head screws at the four top corners under the rubber adhesive pads. Separate the top from the bottom. Two wires come from each of the fans. Cut and twist the two positive wires together and the two negative wires together. Cut the end off the power cord that is NOT the USB end and strip the wire insulation back. You will find a white insulated wire surrounded by another wire. Twist the ends of each separately making sure they are separated by the white insulation. Remove the circuit board using the tiny screws where the switch is and put the power cord end through the switch hole. Tie a knot in the cord to prevent cord from pulling out. Make sure the USB end can reach a USB port on your computer. Carefully test which wires to twist together by touching each to see if the fans turn. One way will work and other way won't. When sure of correct wires, you can solder them together and insulate properly with small wire nuts or electrical tape. Reassemble case with screws and plug in USB cord end when you want the fans to cool your notebook computer. I hope that this helps.

1 Answer changed my motherboard and no longer have a 3 pin connection for the case fan on the motherboard. I know that + goes to yellow and - goes to black but where does the sensor wire go?

An option for you is to just purchase a cheap adapter to plug your case fan into a unused power supply plug, such as one that plugs into a hard drive or optical drive.

The fan rotor is stuck due to accumulation of dust. Take out the fan and clean it. Put a few drops of alcohol or lacquer thinner on the rotor/bushing assembly while manually turning its blades to loosen the hardened dirt until the fan freely spins like the good one. If it does not work, replace the defective fan if spare is available.
