None of my attempts to fix the issue thus far have worked. Will be attempting the trackpad grounding fix I have read about in a couple of days. The "directions" are not specific to this notebook so I am not sure how long it will take to dissasemble all of the required parts and find the required leads etc... Will keep you posted on my progress.
Opened up the notebook and did some discovery on the touchpad. The touchpad is packed in tight and I couldn't find a way to remove it or most of the brackets on top of it to find the grounding pad on the touchpad board. Attached the wire to the metal bracket on top of the, or rather on the bottom of the pad. I then ran a wire to one of the screws that looks like it is grounded. Tested the pad and it did not fail in the first 10 minutes as usual so I closed up the chassis. The wire I used to ground the touchpad is a little thick so the battery didn't sit quite flush. Will have to wait and test out if it is working. The buttons are not pressable, not sure why there isn't anything obstructing it from functioning from what I can see. Other wise the pad is work so far, will continue to keep my eye on it. For screenshots go to the bottom of this article.
Day 2 and so far so good. I have made a modification to the cable I was using. Decided the cable was too thick so I stripped away the plastic from the copper wire that goes under the battery. I then made contact with the original mesh tape that connects the touchpad to the metal grounding frame attached to the keyboard and the touchpad. Also connected the grounding wire to the touchpad metal from underneath. The battery is now able to sit flush preventing obstruction to the notebook case.. If the touchpad continues to work I will post some pics of the modification. One downside so far of the mod is I am not able to push down to click the touchpad buttons. The touchpad tap to click however still works. Will look into this further if the mod continues to work.
Grounding the touchpad seems to have worked. It has been a day and a half and I have not had the crazy freak outs on my touchpad. The notebook never went more than a few hours without the touchpad going crazy so I would call this a success. I will however continue to keep my eye on it. After the touchpad started to work I noticed my mouse/keyboard or both would stop working after bringing the notebook out of suspend. From all of the research I have done this is however an OS issue and not hardware. Will next look into the touchpad clicking issue and the attempt to tackle the suspend problem.
Fixed the touchpad by removing a bracket that seemed to be doing the opposite of what it was intended for. The battery was was pressing on the bracket bending it slightly causing it to push down on the switch under the touch pad. My touchpad is now fully functional and will continue to watch it to make sure it doesn't start freaking out again. Have also posted new photos below of the changes I made.
As it turns out Ubuntu was causing an issue with the USB bus when sleeping requireing a reboot of the bus after sleep. Implemented a work around in the bios preventing the USB bus from powering down during sleep. Now when the notebook comes out f sleep the mouse works properly. The keyboard now works as well, the only change I made for the keyboard is disabling wake on keyboard in the bios.
Now that these changes have been discovered my major complaints with this notebook have been satisfied. I hope this information helps you fix the touchpad on your Radius 12 4k notebook.
Since using the Toshiba Satellite Radius 12 notebook the Touch Pad has been freezing and been rather useless. Wanting my notebook to be fully functional and not have to carry an external pointing device with me every where I go I set out on a quest to find a solution to the pointer problem. Since researching this issue I discovered it is not isolated to the Radius 12, it also is found on the Dell XPS 13 according to this article here. Knowing this issue exists on other platforms I am creating a new article to keep track of my progress. On to the heart of this article.
During my time troubleshooting and researching I have discovered three possible workarounds to the touch pad problem.
Till next time..............
Below are the revised changes I made to the grounding wire for the touchpad. Also, the first picture shown is the bracket I remove from the bottom of the touchpad.
