Hi All,
Is it possible that the USB cable from the printer could cause the following:
- shocks when touching the computer case
- eventual loss of some or all USB ports in the computer
The first time this happened, attempts to print to the printer started giving errors, reinstall did nothing, plugging the printer into different USB ports did nothing. The computer still worked, but I would get shocks (heavier than a static shock) touching the case, any USB port, or my mouse's USB connector (exposed metal at the mouse).
The motherboard and power supply were replaced. A UPS was purchased and everything was plugged into it.
The second time, attempts to print gave errors, touching the case gave a shock, plugging the printer into a different USB port worked. The next morning the machine would not even boot into safe mode.
The motherboard has been replaced with a different type; the CPU and the hard drive have been replaced.
This computer was built by a technician.
Questions:
- Would replacing the USB cable with a parallel connection help? I believe parallel cables do not carry power.
- Should I call HP? The printer is under warranty.
My situation: partially disabled, equipment being provided by a state grant. This tech says he won't repair the machine again if it fails. Computer is less than 6 months old. Computer contains a fancy video board with connections to copy video to burn DVDs.
Any help you can provide is appreciated.
