I'm not sure what I did - the touchpad was behaving VERY badly, I tried to download and reinstall drivers (used Synaptics because I could not tell what was on my machine)...but now I have nothing:
running Windows 7
Under "Input" in System Information (not Device Manager) - "Keyboard" has USB Input Device (Logitech Download Assistant) [that's a Logitech M505 mouse with USB bluetooth - the built-in Atheros USB hasn't worked in years] and PS/2 Standard Keyboard. "Pointing Device" has only HID-compliant mouse (driver is mouhid.sys). Nothing for PS/2-compliant mouse, or any touchpad.
With system diagnostics I get the following:
| Symptom: | Device cannot start. |
| Cause: | A device has a configuration problem that prevents it from starting properly. |
| Details: | The device, PS/2 Compatible Mouse, cannot start properly. It may not have the correct driver installed or may be experiencing a hardware failure. The Plug and Play ID for this device is ACPI\SYN1B5F\4-C721B88-0. |
| Resolution: | 1. Verify the correct driver is installed. |
| | 2. Try updating the drivers using Windows Update. |
| | 3. Check with the manufacturer for an updated driver. |
| | 4. Attempt to uninstall and then reinstall the device using Device Manager. |
I don't know which touchpad I have, synaptics or elantech, and since it doesn't show up on device manager or system information, I cannot tell. The Synaptics driver said it would not install because it could not find any applicable device. The Acer website is not telling me what driver I need from my serial number or SNID - it says Service Not Available.
Please advise!!
