Touchpad of notebook sometimes does not work after booting

Question

I've freshly installed Windows 7 final on a Fujitsu Siemens Esprimo Mobile V5505. It is all installed with default drivers, since Fujitsu Siemens has yet not offered any Win7 drivers.

Problem is, roundabout every 4th time I start the notebook, the touchpad does not work. These times, in the event log will be two events from the source i8042prt, one error (EventID 22) stating "could not set the mouse sample rate" followed by one warning (EventID 18) "The device sent an incorrect response(s) following a mouse reset.".

After a reboot the system usually works like charm.

Any ideas what might cause these glitches? There is no external hardware attached, I can't see any pattern what might cause this.

Answer 1

It sounds like a device driver issue. You can try to find a driver that supports your touchpad, even if Fujitsu hasn't released an official one yet. Find out what touchpad you are using in the device manager and try to track down a current driver at that company's site.

For example, I have a Lenovo Thinkpad, that uses a Synaptics touchpad. I could go to Synaptics.com and download their driver - although I don't need to since Lenovo provides it on their site and through their update software.

Another thing to consider is that this might be an actual device failure. Usually, the default Windows drivers are good enough when it comes to HIDs (human input devices like mice and keyboards). You could take it for a technical inspection, if still under warranty.

Answer 2

I think that most of the time it is a lack of moisture in your fingers. I am new to laptops, but I work with electricity a lot and I have a small device that can be used to check fuses and light bulbs. To use this great little tool you touch one end of the fuse with finger and touch the other end of the fuse with the end of this tool while touching a metal contact point on this tool with one of your fingrs that you are holding the tool with. If your fingers are very dry the tool will not work. If I just moisten my fingers that come in contact with the fuse and the contact point on the tool the tool will work great.
