I have bought the U9200 for years. Every thing seemed fine except one day I used the LAN instead of WiFi for data retrieval. It was OK while using LAN. However, by the time I switched to WiFi, I lost the network connection. I tried to see the setup BIOS if any setting went wrong. Yet, to my further dismay that no matter what combination of boot sequence I used, the XP keep on rebooting. Error message shew 'PXE-E61: Media test failure, check cable'. I tried to boot using the usb, yet XP setup shew no D: drive was found. In fact the CD was out of order (malfunctioned for a year). I don't think there is any major damage to U9200 as I went to the shop and checked the hard disk is OK. How can I have it fixed. Please help!
