That's 5445?

Yes, but it was me who tried it on a G3420, not D.Draker, and it worked on a desktop PC. Again, Pentium G3420, 32bit XP.

I assume they did something to that driver since it'smarked as "FORCED", but I hadn't dig deep enough to be sure.

I noticed a side-effect when using Windows XP 64-bit on my Dell Inspiron 3542 after using the modded ACPI.sys @K4sum1 gave me; The mouse doesn't work, and is not detected at all, and it tells me to plug my laptop into a charger, even though it is. These problems do not happen on Windows 7 and later. One thing I also noticed is that this touchpad is an I2C/PS2 combo touchpad, but, this one is different than later ones. Usually, when you have a touchpad like this, there would be a setting in the BIOS to switch between I2C and PS/2 (so, for Acer's, it would be Advance for I2C and Basic for PS/2), but, for this Dell, there is no setting in the BIOS and it is dependent on the OS installed. For example, XP 64-bit has no mouse detected whatsoever, Windows 7, it is PS/2, and Windows 8 and later, it is I2C. I have not even tried Vista on this due to the Haswell bugs, but I wouldn't mind trying that if a fix is found for that. I'm gonna also post this in the ACPI thread as well to see if a solution can be found.

I guess my E7250 is PS/2 only as it just works. I also didn't have the charger issue, however I don't have a working battery so might be that idk.
