I have Dell Inspiron 15 7548 with this problem too. Touchpad works for a while, then stops. Sometimes it comes back. Sometimes the cursor jumps around the screen while typing. The touchpad stopped on this site as I was clicking on the subscription fields. Its working now. But sometimes it never comes back unless I reboot. Sometimes it works but doesn't scroll. Sometimes it doesn't zoom. Sometimes it zooms instead of scrolls. Sometimes it does nothing and the mouse pointer just sits there. Sometimes the mouse pointer disappears. In a pinch I can use the touch screen but I don't like putting finger prints on the beautiful 4K display.
Win 8.1, Device manager shows Human Interface Devices, Touchpad, No driver files required. Also shows two mouse drivers, each HID Compliant Mouse. I'm using a Logitech usb mouse on a single usb port. This usb mouse always works and unfortunately is the only way I am not constantly rebooting. Rebooting is not a fix for this issue.
Ha! Very resourceful. Me, I just always always have a wireless mouse in reach. Or nearby. But it pretty much exhibits the same behavior all the time. Having no clear reason. Sometimes I'd think it was my hands temperature. If got sweaty, no good.
I'm hoping this new bios firmware is the fix we all been waiting for. I haven't noticed an outage since new bios but who knows. I'll have to wait a few days to be able to tell for sure.
hi @burgesszachary1, you should try putting ipad screen guard on it, I also thought it was because my hand sweats like a waterfalls. because it works nice when my hands aren't sweatin, there's one time when the trackpad error came up while my hand is sweating then I tried to put a plastic cover on it because the trackpad is full of sweat, and it works, that's how the idea of putting an ipad screen guard came up. it works fine. you should try it.
