Now a problem with mouse driver

If the power line for that mouse is disconnected (ie fuse or automatic resetting circuit breaker open), then the mouse is powered via signal lines. That would cause corrupted serial data - would explain the symptoms I read. An LED and a 200 ohm resistor temporarily touching the two pins would even test for that. Your problem is why more responsible computer manufacturers provide comprehensive hardware diagnostics for free. Many who buy computers on price do not get those (what you need to solve the problem) diagnostics. Numerious other useful facts might be provided if you could provide then necessary measurements or access. Some facts may have already been provided. But too much information is scattered among other posts that recommend nonsense - such as a defective BIOS. If s BIOS is corrupted, then BIOS completely crashes the computer. Anyone with basic programming knowledge would have known that. If I was doing this (without diagnostics), I might write a short program to read data direct from the mouse - to actually see what the mouse is outtputing. Or measure voltage on the appropriate wire with a meter. But that assumes I had to fix it. Apparently the loss is acceptable. |
