I've had this laptop for about a month and the touchpad (ETPS/2 Elantech Touchpad) was working fine. Yesterday that changed. I had this weird issue with my battery where it didn't recognize that I even had a battery (acpitool said battery: not available) and therefore it would turn off right when I unplugged the charger, as if it were a desktop computer and not a portable laptop with a rechargeable battery. Anyway, after one of these shutdowns my touchpad stopped working. Now the battery is working fine but the touchpad is not. I checked out all of the similar questions on this site but none of them worked or matched my circumstances.Here are the details:No X11 cursor shows up.I'm running debian jessie with kernel 3.16.0-4-amd64.My touchpad is both recognized and enabledmy synaptic touchpad package is fully updatedxev shows no response from any interaction with the touchpada usb mouse works, which I'm using right nowI don't have an xorg.confThanks all. I'll add anything that will help if asked. I cannot figure out what could be causing this. @debian:~$ xinput Virtual core pointer                      id=2    [master pointer  (3)]    Virtual core XTEST pointer                id=4    [slave  pointer  (2)]    Mitsumi Electric Apple Optical USB Mouse  id=10   [slave  pointer  (2)] Virtual core keyboard                     id=3    [master keyboard (2)]     Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]     Power Button                              id=6    [slave  keyboard (3)]     Video Bus                                 id=7    [slave  keyboard (3)]     Power Button                              id=8    [slave  keyboard (3)]     Sleep Button                              id=9    [slave  keyboard (3)]     HD WebCam                                 id=11   [slave  keyboard (3)]     AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]relevant crap in /var/log/Xorg.0.log:[     3.878] (II) config/udev: Adding input device ETPS/2 Elantech Touchpad (/dev/input/event2)[     3.878] (**) ETPS/2 Elantech Touchpad: Applying InputClass evdev touchpad catchall[     3.878] (**) ETPS/2 Elantech Touchpad: Applying InputClass touchpad catchall[     3.878] (**) ETPS/2 Elantech Touchpad: Applying InputClass Default clickpad buttons[     3.878] (II) LoadModule: synaptics[     3.879] (II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so[     3.880] (II) Module synaptics: vendor=X.Org Foundation[     3.880]    compiled for 1.16.0.901, module version = 1.8.99[     3.880]    Module class: X.Org XInput Driver[     3.880]    ABI class: X.Org XInput driver, version 21.0[     3.880] (II) Using input driver 'synaptics' for 'ETPS/2 Elantech    \Touchpad'[     3.880] (**) ETPS/2 Elantech Touchpad: always reports core events[     3.880] (**) Option Device /dev/input/event2[     3.913] (II) synaptics: ETPS/2 Elantech Touchpad: ignoring touch events for semi-multitouch device[     3.913] (--) synaptics: ETPS/2 Elantech Touchpad: x-axis range 0 - 3080 (res 0)[     3.913] (--) synaptics: ETPS/2 Elantech Touchpad: y-axis range 0 - 1120 (res 0)[     3.913] (--) synaptics: ETPS/2 Elantech Touchpad: pressure range 0 - 255[     3.913] (--) synaptics: ETPS/2 Elantech Touchpad: finger width range 0 - 15[     3.913] (--) synaptics: ETPS/2 Elantech Touchpad: buttons: left right double triple[     3.914] (--) synaptics: ETPS/2 Elantech Touchpad: Vendor 0x2 Product 0xe[     3.914] (--) synaptics: ETPS/2 Elantech Touchpad: touchpad found[     3.914] (**) ETPS/2 Elantech Touchpad: always reports core events[     3.968] (**) Option config_info udev:/sys/devices/platform/i8042 /serio1/input/input2/event2[     3.968] (II) XINPUT: Adding extended input device ETPS/2 Elantech   Touchpad (type: TOUCHPAD, id 13)[     3.968] (**) synaptics: ETPS/2 Elantech Touchpad: (accel) MinSpeed is now constant deceleration 2.5[     3.968] (**) synaptics: ETPS/2 Elantech Touchpad: (accel) MaxSpeed  is now 1.75[     3.968] (**) synaptics: ETPS/2 Elantech Touchpad: (accel) AccelFactor is now 0.061[     3.968] (**) ETPS/2 Elantech Touchpad: (accel) keeping acceleration scheme 1[     3.968] (**) ETPS/2 Elantech Touchpad: (accel) acceleration profile 1[     3.968] (**) ETPS/2 Elantech Touchpad: (accel) acceleration factor: 2.000[     3.968] (**) ETPS/2 Elantech Touchpad: (accel) acceleration threshold: 4[     3.968] (--) synaptics: ETPS/2 Elantech Touchpad: touchpad found[     3.968] (II) config/udev: Adding input device ETPS/2 Elantech Touchpad (/dev/input/mouse1)[     3.968] (**) ETPS/2 Elantech Touchpad: Ignoring device from InputClass touchpad ignore duplicates
