hELLO qUEEN eVIE,
iTS mE, y'ALL
Yes, I can use my touchpad.
Interesting, just as 'I' thought.
In fact, I tried this very thing yesterday, as I had the idea that this may have an effect.
I did this just to see if there was a difference, or to see if anything else showed up.
I unplugged the mouse.
When I then went to the Device Manager, the PS/2 Compatible Mouse driver still showed up in this list.
In fact, just as before under this section, "the mice and other pointing devices" section, this was the only thing there!
This does not occur when the mouse is plugged in.
When the mouse is unplugged, and I only use the touchpad -- this is when you see it.
With the touchpad, the cursor steers normally with your fingers when you use it.
Sometimes, after you take your hands off of the laptop and wait several seconds to a minute, the cursor decides to just start floating in one direction in a slow but steady course continually across the screen
When you are not touching the laptop, you can sit and watch the cursor just drift on down the screen slowly.
But now that I am trying to analyze it, I have noticed that the cursor seems to be drifting in a "/" diagonal direction, either up or down, but mostly down.
Though it may have gone other directions before.
There is also another interesting facet to this whole thing:
When I press the touchpad top or bottom left or right button, the cursor ALWAYS immediately does a quick strafe across the screen, making it difficult to point and click on specific boxes on the screen and for the computer to have "seen" that I had been pointing at that exact spot 'before' I clicked the touchpad button.
Example: I am pointing here --> "X", but when I press the touchpad button, the cursor and the computer registers the click as this point, "Y" here, instead.
However, the distance between point and click is only about 1", so it would be, "X" and --> "Y".
In conclusion, it is very difficult to successfully click a box or such.
I became concerned recently when I had had my computer on for several hours, during which time the cursor worked just fine with the mouse plugged in.
After this point, after I had left the room for some time and came back, 'now' the cursor ALSO started to drift with the mouse!!!!!!!!
Oh NOOOO!! This can't be happening. This is not good.
It has NEVER done this before with the mouse plugged in!!!!!!!
I switched mouses and now it worked just fine as normal. Phew! [I wipe the sweat off my forhead]
That was close. Much too close!!!
I got this computer used.
For as long as I have had this computer the touchpad had always done the "Drifting" and the "Pointing Strafe" effect.
However, occassionally, the computer won't do this.
Like for example, yesterday, I didn't think that if I unplugged the mouse and tried to go to the Device Manager, that I would be able to do it with the touchpad, and that I would be reduced to using the "TAB" key the whole way -- and major and slowly painful way of navigating the computer.
But 'instead', the computer reacted without any adverse effects, though this could have something to do with how long the cursor is unplugged, as when the laptop had its mouse unplugged for several hours, then the effects happen.
But I have not experiemented with what could be causing this or how, since it seems kind of random sometimes, and hard to pinpoint.
Just now, just as you said, I double tested it by unplugging the mouse and going to the Device Manager for a second time.
It works just fine, with no problems to either the "Driting" and "Button Strafing", though I may not have waited long enough for the effects to take place once again.
The mouse was unplugged for several seconds before I attempted to try this both times.
