Laptop is an advent 4401. So, I've got problems with my touchpad, in as much as it doesn't work. To make it work I have to go into the device manager and uninstall the 'Synaptics PS/2 Port Pointing Device', then restart and it works fine. Only problem is Windows automatically detects it when you restart and the next time you restart it finishes the installation and then the touchpad doesn't work again. I can't disable, only uninstall. I can disable it through the mouse options in Control Panel but that doesn't make any difference. I've tried using updated synaptic touchpad drivers and none at all (just the generic one's Windows installs), even did a fresh install of XP (I'm giving it to my dad anyway), but that didn't make any difference either. The BIOS is pretty limited and there is nothing resembling legacy USB support so I can't turn that off. I also found two files under Driver Details through Device manager; C:..WINDOWS..system32..drivers..i8042prt.sys and C:..WINDOWS..system32..drivers..mouclass.sys, deleted both of those files (just to see if it would make any difference), but it didn't do anything. As soon as you restart it doesn't work again. I'm getting around it at the moment by disabling the plug and play service, but that's not a fix (my dad will be mainly using it for watching movies and tv on the go, so needs the plug and play functionality for external devices). The laptop is fairly new (a few months), and I haven't even been using it (the touchpad) for like 2-3 months, it's been on my desk being used with synergy and my normal mouse/keyboard. I only noticed it didn't work when I went to take it somewhere the other day and I couldn't use the touchpad. That's why I wasn't too bothered about reinstalling XP, as I thought maybe the synergy installation had messed with it somehow, but even after a fresh install it's the same. The touchpad works, just not when Windows installs what it wants to to get it to work, if I could somehow stop just the auto update for the touchpad it would be fine. Any thoughts?
