There may be several things to check:
Miscunfigured system:
- Try to deactivated your LAN connection and re-activated it (or reboot the system, the results would be the same: the driver gets reset)
- Check the setting of your connection - DHCP on/off? When no DHCP -> IP, subnet and gateway (for example: 192.168.0.5, 255.255.255.0, 192.168.0.1)
- Shut down firewalls (Windows xp offers a build-in firewall which might be activated be a Microsoft security patch)
- Keep the connection as simple as possible to spot the point of error.
Broken hardware:
- check if there are any LED signals at the network port on your computer, most network ports show two LEDs above the RJ45 plugin, one should be green all the time, the other one will flash when there is traffic on the line. When there is no LED lit, there is no (electrical) connection between the Hub/Switch and your computer.
- Try exchanging the patch cable
- Try resetting the Hub/switch
- Last shot: Try reinstalling your network driver (it is unlikely but might be a driver problem)
It indicates that it is a spur off of the mainline highway (Interstate 76). In this case it does not reconnect to the mainline but to a different mainline (Interstate 95).
PRESUMING you have already unplugged it and removed the cover, ground yourself by attaching a grounding strap to your wrist and the computer case to prevent static discharge
This message means someone tried to start the computer with the case open, AND that the BIOS is set to halt if the chassis intrustion switch indicates that the case is open.
Disconnect the negative battery terminal and leave it unplugged for 30min or so. On most odb2 vehicles there is a capacitor system that maintains a charge for a while. This is for temporary data storage, airbag deployment, etc. in case of power loss. With some cars/trucks depressing the brake pedal while the battery is unplugged will drain it sooner.
A computers power supply can cause a shock even when unplugged but it's not dangerous. The monitor stores enough power to kill for many years after being unplugged. Never open the case of a monitor.
A case protects a computer when it is dropped.
Case
Yes bring him to the vet just in case
That can be a problem with the fuse, the switch might be faulty. The motor at the transfer case might be unplugged.
Simply put, the monitor is not receiving a signal from the computer because.... A. The computer is off B. The signal cable has come unplugged somehow or, worst case scenario.. C. The power interruption (and resulting surge) has fried something inside your computer. I seriously doubt that there is anything with the monitor, if that were the case it wouldn't work well enough to show you the floating box.
2U indicates a case that occupies two spaces in a rack.
in any case
