It behaves in a way that makes me think it is not hardware-related.
This is on a Samsung X1 laptop running Win XP SP2. If I plug in an external USB mouse then this works fine untl the problem happens again. This laptop is made with a keyboard pointing stick but has no touchpad.
It's like this:
1. At the signon screen and for a few minutes after starting up, the mouse is dead in the water. The laptop pointing stick does not work at all.
2. After a few minutes the mouse is suddenly available and responsive, all seems to work fine. (As if some piece of software has kicked in)
3. Suddenly the mouse pointer runs to bottom left corner of screen. If I use the real mouse I am battling against it, pushing the opposite way. While it kicks in, it's just like someone else is using another mouse in the opposite direction on the same pointer. Mouse may then suddenly decide to head upwards and stick at top of screen, although bottom left is the most common.
4. then it works fine for a while- say 5 - 30 mins, depending, then without warning it repeats aa in number 3. or similar again.
I have tried a lot of googles, which talk about hardware issues. i don't think it is hardware because of the way it kicks in for a minute or so and then stops, on and off. Also the same thing happens with an external mouse. I have now managed to disable the built-in pointer and plug in a USB mouse, but the same thing happens. This means the problem is not in the mouse hardware.
I've uninstalled the mouse and reinstalled the drivers. Every time I uninstall the mouse , by deleting it in device manager it reinstalls itself. The external normal USB mouse can be uninstalled and reinstalled and disabled but the embedded pointing device mouse does not let itself be deleted in device manager. It stays permanently in Device manager even when deleted.
I went through the registry manually and removed all traces of the mouse driver. I copied the keys for a standard microsoft mouse driver. Then I hit add/remove programs and the thing reinstalled.
I can't use my laptop a lot nowadays because the *** mouse is doing this dive all over the place without warning.
A lot of the time it is rock-solid, no diving or drift then all of a sudden it takes off as if someone is dragging it to the left and down. then after some time this stops dead.
I've tried ad-aware and I am running spybot and found nothing yet.
I've tried using Spy from the C++ SDK to see where the mouse messages are coming from (which window using process explorer) but the tool shows you the messages in the window receiving them, it does not show you which EXE is axctually generating them, which is a shame.
Any advice would be very gratefully receicved. Samsung tech support said reinstall the driver, then reinstall windows, then if it is still a prolem they will look at it . I'm not keen to reinstall everything since everything else is fine.... I found one other user who had this problem, who said it went away by itself.
Any advice would be gratefully received. I've started by turning off anything I can and by looking at running processes and services. Nothing there that I can see, but maybe there is and I can't see it . . .
