System IP Address not found and says Media is Disconnected ? I have tried ipconfig /release and ipconfig /renew but didn't get result...Please solve this problem

Re: Communications

  • IP addresses are four numbers separated by periods. The four numbers can each range from 0 to 255. They are used on the Internet and on local networks. A current Internet IP address is Local network IP addresses all start with 192.168 and an example is


  • When the IP address of each computer on the network is checked, two will be the same. The IP address of a computer can be found by running "cmd" and then "ipconfig" in the black pop-up box which appears. Each computer will show an address like and two will be the same, resulting in the conflict message.


  • The IP address of one of the two machines which has the same address will have to be changed. IP addresses are set in the Network Properties section under Protocol (TCP/IP). The last three numbers of one of the conflict machines must be changed to a number different from all the other IP addresses. The machine must be restarted and the error message will no longer appear.

Compaq BIOS update F.37 bricks Presario?

BIOS is not corrupted. yo download the wrong BIOS. either for the worng machine (I do think so-twice?). or you download the earlier version.
nothing you can do.
go to ebay or criglist see if any body is selling the same motherboard that works.
get it and replace the BIOS chip, you don't nee to replace the whole motherboard. just the BIOS chip.

Targus chill mat not working properly

This problem is being caused by a wire becoming disconnected from the switch in the usb power cord. The easiest way to solve this problem is to open the switch using a flat blade like a knife, and either reconnect the loose wire yourself or to completely remove the switch and connect the wires together completing the circuit and allowing the fan to operate. I hope this helps.
